Heart health innovation is at a major moment in history — and Houston is at the center of it.

Last summer, Dr. Joseph Rogers, president and CEO of the Houston-based Texas Heart Institute, joined the Houston Innovators Podcast to share how he came to be at the helm of THI, as well as the incredible technologies the institute is working on to address heart failure, a global epidemic affecting at least 26 million people worldwide, 6.2 million adults in the U.S.

This month, one of THI’s technologies reached a major milestone. BiVACOR, a Houston company successfully implanted the company's first Total Artificial Heart in a human. The device was implanted in the patient on July 9. Eight days later, a donor heart became available and was transplanted into the patient, removing the TAH, establishing the device as a successful bridge-to-heart-transplant solution for patients, THI reported.

In addition to this breakthrough in health tech, THI is focused on addressing Cardiometabolic Syndrome at a new conference on Friday, August 23, in Houston. The full-day symposium will take place in collaboration with Arianna Huffington, the founder and CEO of Thrive Global. Dr. Rogers is co-directing the program with Dr. Stephanie Coulter, medical director for THI Center for Women’s Heart & Vascular Health.


In the episode, Rogers explains why he's bullish on Houston and THI leading heart health innovation alongside other health care organizations — nonprofits, universities, local government — to collaborate in ways never been done before. And THI is dedicated to this mission.

"We should act as a convener," Rogers says. "Houston is the place to do this.

"The reason I think this is such an important community to address this problem is it's the most diverse city in the United States. And I've never lived anywhere or heard of another city that I was so convinced believed they could do anything they set their minds to. It's about making the community aware of the problem and a potential solution — and then working on trying to solve it," he continues. "But I think all of the pieces are here to show the world how to do this at a community level."

Houston health care organization to host conference about cardiac health crisis

heartbeat heroes

Cardiometabolic Syndrome (CMS) is a major danger to public health around the world. No one knows this better than the Texas Heart Institute, which will host its first Cardiometabolic Syndrome Conference on Friday, August 23.

The conference’s subtitle, “A population health crisis” brings home the unpleasant reality that many recent projections anticipate drastic growth for the condition.

CMS is a combination of interrelated metabolic maladies that are risk factors not just for cardiovascular disease, but also fatty liver disease and cancer. According to THI, the underlying conditions for CMS may include hypertension, insulin resistance and type II diabetes, elevated serum lipids, and obesity, all increasingly common among the global population.

The conference will address the crisis with the help of Arianna Huffington, the founder and CEO of Thrive Global and former editor in chief of The Huffington Post Media Group. Thrive's behavior change technology may be a possible step in the right direction to prevent CMS.

“We are at a pivotal moment in the fight against cardiometabolic syndrome,” Huffington says in a press release. “This conference is not just a gathering of experts, but a catalyst for innovative thinking and actionable solutions. By integrating diverse perspectives and harnessing the collective expertise of our attendees, we can transform disease prevention strategies and improve health outcomes globally.”

THI experts will both lead the conference and participate in discussions. The co-directors are renowned cardiologists, Dr. Joseph G. Rogers, CEO and president of The Texas Heart Institute, and Dr. Stephanie Coulter, medical director for THI Center for Women’s Heart & Vascular Health. Topics will include screening and treatment guidelines, the impact of CMS on children, and integrating social determinants of health into clinical practice. Health professionals among the attendees will include cardiologists, hepatologists and endocrinologists.

“We must transcend traditional healthcare solutions to effectively tackle the rising burden of cardiometabolic syndrome,” says Rogers. “By bringing together key stakeholders and encouraging collaboration among multidisciplinary healthcare professionals, we aim to ignite groundbreaking ideas and forge novel strategies to combat this pressing health crisis."

Speaking of novel technologies, THI and BiVACOR this month reported that they successfully implanted the company's first Total Artificial Heart in a human at Baylor St. Luke’s Medical Center in the TMC.

Houston medical device startup implants artificial heart in first human patient

big win

Heart health tech company BiVACOR and The Texas Heart Institute announced that they successfully implanted the company's first Total Artificial Heart in a human at Baylor St. Luke’s Medical Center in the TMC.

The milestone is part of an FDA-approved early feasibility study that will test the safety and performance of the TAH device, which is based on a magnetically levitated rotor that takes over functions of a failing heart while a patient is awaiting a heart transplant, according to a statement from the organizations.

The "bridge-to-transplant" device could support an active adult male, as well as many women and children suffering from severe biventricular heart failure or univentricular heart failure.

"With heart failure remaining a leading cause of mortality globally, the BiVACOR TAH offers a beacon of hope for countless patients awaiting a heart transplant,” Dr. Joseph Rogers, president and CEO of THI and national principal investigator on the research, says in a statement. “We are proud to be at the forefront of this medical breakthrough, working alongside the dedicated teams at BiVACOR, Baylor College of Medicine, and Baylor St. Luke’s Medical Center to transform the future of heart failure therapy for this vulnerable population.”

BiVACOR received approval from the FDA for the early feasibility study in late 2023 and has four other patients enrolled in the study. At the time the study was approved, 10 hospitals were enrolled as possible sites.

“I’m incredibly proud to witness the successful first-in-human implant of our TAH. This achievement would not have been possible without the courage of our first patient and their family, the dedication of our team, and our expert collaborators at The Texas Heart Institute ... our TAH brings us one step closer to providing a desperately needed option for people with end-stage heart failure who require support while waiting for a heart transplant. I look forward to continuing the next phase of our clinical trial,” Daniel Timms, PhD, founder and CTO of BiVACOR, adds.

About 100,000 patients suffering from severe heart failure could benefit from BiVACOR’s artificial heart, the company says. Globally, only about 6,000 heart transplants are performed each year, while 26 million people worldwide are affected by heart failure.

BiVACOR was founded in 2008 and maintains its headquarters in Houston, along with offices in Huntington Beach, California, and Brisbane, Australia.

To date, the company has raised nearly $50.8 million, according to CB Insights. The company raised $18 million in 2023, and $22 million in 2021.

Earlier this year, BiVACOR named a new CEO in Jim Dillon, a longtime executive in the medical device sector.

Last summer, Rogers joined the Houston Innovators Podcast to share his excitement with THI's innovations.

Houston health tech innovator collaborates on promising medical device funded by DOD

team work

The United States Department of Defense has awarded a grant that will allow the Texas Heart Institute and Rice University to continue to break ground on a novel left ventricular assist device (LVAD) that could be an alternative to current devices that prevent heart transplantation and are a long-term option in end-stage heart failure.

The grant is part of the DOD’s Congressionally Directed Medical Research Programs (CDMRP). It was awarded to Georgia Institute of Technology, one of four collaborators on the project that will be designed and evaluated by the co-investigator Yaxin Wang. Wang is part of O.H. “Bud” Frazier’s team at Texas Heart Institute, where she is director of Innovative Device & Engineering Applications Lab. The other institution working on the new LVAD is North Carolina State University.

The project is funded by a four-year, $7.8 million grant. THI will use about $2.94 million of that to fund its part of the research. As Wang explained to us last year, an LVAD is a minimally invasive device that mechanically pumps a person’s own heart. Frazier claims to have performed more than 900 LVAD implantations, but the devices are far from perfect.

The team working on this new research seeks to minimize near-eventualities like blood clot formation, blood damage, and driveline complications such as infection and limitations in mobility. The four institutions will try to innovate with a device featuring new engineering designs, antithrombotic slippery hydrophilic coatings (SLIC), wireless power transfer systems, and magnetically levitated driving systems.

Wang and her team believe that the non-contact-bearing technology will help to decrease the risk of blood clotting and damage when implanting an LVAD. The IDEA Lab will test the efficacy and safety of the SLIC LVAD developed by the multi-institutional team with a lab-bench-based blood flow loop, but also in preclinical models.

“The Texas Heart Institute continues to be a leading center for innovation in mechanical circulatory support systems,” said Joseph G. Rogers, MD, the president and CEO of THI, in a press release.

“This award will further the development and testing of the SLIC LVAD, a device intended to provide an option for a vulnerable patient population and another tool in the armamentarium of the heart failure teams worldwide.”

If it works as hypothesized, the SLIC LVAD will improve upon current LVAD technology, which will boost quality of life for countless heart patients. But the innovation won’t stop there. Technologies that IDEA Lab is testing include wireless power transfer for medical devices and coatings to reduce blood clotting could find applications in many other technologies that could help patients live longer, healthier lives.

Houston medical device company with long-lasting artificial heart reaches FDA milestone

feasibility focused

A Houston company with a breakthrough heart health tech has received a green light from the FDA.

BiVACOR, a Houston-headquartered medical device company, has received FDA approval for its Total Artificial Heart (BTAH) IDE first-in-human early feasibility study (EFS). The BTAH device itself is designed to take over all function for patients with heart failure. The BTAH is roughly the size of a human fist, which means that, while it could support an active adult male, it may also fit many women and children.

Led by CEO Thomas Vassiliades, a former heart surgeon, BiVACOR is based on a system of magnetic levitation. “Our pump is just one moving impeller that sits in the middle of the housing where the blood is. Imagine an artificial heart — the container that has your blood — and the device spinning in the inside — basically a wheel spinning your blood to the rest of your body. The device is suspended by magnets — it's not touching anything,” Vassiliades told InnovationMap in a podcast earlier this year.

Because of that, BiVACOR could potentially last for a patient’s entire life with no wear — something, Vassiliades explains, is new to the field.

The EFS includes 10 hospitals enrolled as possible sites and is slated to begin in 2024. One location is Houston’s own Texas Heart Institute.

“I am eager to begin the BiVACOR Total Artificial Heart EFS to evaluate what I believe is a promising and potentially life-saving technology,” Joseph Rogers, CEO of the Texas Heart Institute, says in a press release. “The implantation of a TAH system is a potential treatment option for patients with heart failure who need support while on the heart transplant waiting list and for those who do not qualify for a transplant. The BTAH is designed to replace the function of the native heart completely. It is an impressive technology, and I am excited to see the potential of BTAH in treating patients with severe heart failure.”

BiVACOR’s chief medical officer is Texas Heart Institute cardiac surgeon William Cohn. He said that this EFS is a “critical milestone” for him and the BiVACOR team.

“This device will provide a unique approach to help patients currently with limited clinical options,” he explains.

The upcoming study is planned for biventricular heart failure patients who need a mechanical circulatory support device as a bridge to later transplantation. However, the team hopes that future studies will follow to chart the BTAH’s success with short-term and long-term destination therapy.

Massive $32M gift from former patient, new UH deal pump big changes into Houston organization

all heart

Leadership at The Texas Heart Institute has two major things to celebrate. First, it just received a $32 million donation from a patient — the largest charitable donation in its history.

Shortly after that news came out, the institute announced a new partnership with the University of Houston Tilman J. Fertitta Family College of Medicine that allows those UH medical students to join a clinical rotation at The Texas Heart Institute. The alliance means valuable insights and experience with both inpatient and outpatient cardiology for UH's future doctors.

"Students will have the chance to develop their skills in the diagnosis and management of cardiovascular conditions and will be taught by outstanding clinical educators,” said Dr. Joseph G. Rogers, president and CEO of The Texas Heart Institute and heart failure specialist at The Texas Heart Institute Center for Cardiovascular Care, in a press release announcing the news.

A game-changing gift that's all heart

As for that mammoth gift, the $32 million donation comes from Dr. Frederick M. Weissman, a neurologist from New York who was a patient at the Institute 40 years ago. Fittingly, huis gift will be used to support cardiovascular research.

This isn't Weissman's first gift to the institution. That came following his experience there in the mid-1980s, when he was treated by world-renowned cardiac surgeon Dr. Denton A. Cooley.

In November of 1986, Weissman wrote a check for $5,000; another followed the next month, with a note that read, in part, “my conscience compels me to make another contribution to The Texas Heart Institute. I don’t think I could ever repay you for what you and your staff have done for me.” Weissman and Cooley would go on to be friends throughout their lives.

When Dr. Weissman died in 2005, he left The Texas Heart Institute $500,000. The organization recently received the residual of his estate — valued at more than $32 million.

“Those of us who were fortunate enough to work with and be trained by Dr. Cooley know he was much more than just an incredibly gifted surgeon," renowned transplant surgeon and Co-director of THI’s Center for Preclinical Surgical & Interventional Research, Dr. O.H. “Bud” Frazier, said in press materials announcing the donation. "He established lifelong relationships with his patients and encouraged all of us to do the same. Dr. Weissman’s extraordinary generosity reflects the impact Dr. Cooley still has on the Institute he founded.”

A big leap for THI and the Coogs

Looking ahead, this game-changing gift and new affiliation with UH promises big things for students, doctors, researchers, and patients.

Medical students in rotation at The Texas Heart Institute will be exposed to progressive clinical care, allowing them to gain a deep understanding of the etiology, pathophysiology and management of cardiovascular disease from prevention to the most contemporary treatments available today. This level of hands-on experience is invaluable for future physicians, and will certainly contribute to the advancement of cardiovascular medicine.

"We are honored to launch this new affiliation with Fertitta Family College of Medicine,” said Dr. Jorge Escobar, director of undergraduate medical education at The Texas Heart Institute. "With new advances in diagnostic imaging, bedside testing, and clinical trials coupled with the complex care we provide to our patients, the rotation will be an impactful experience for the students."

Pumping with growth

Meanwhile, THI recently established The Texas Heart Institute Research Innovation Fund to propel the next generation of cardiovascular research by sparking discovery, supporting innovation, and recognizing excellence in high-risk, high-reward scientific exploration.

To that end, $5 million of the Weissman bequest has been designated to match philanthropic commitments of $10,000 or greater made to THI’s Research Innovation Fund and its priority initiatives in 2023, allowing donors the opportunity to double the impact of their research investment.

Founded in 1962, THI performed the first successful heart transplant and total artificial heart implant in the United States. It has gone on to become one of the world's leading institutions for cardiovascular treatment and research.

Houston space tech co.'s lunar lander touches down on moon — condition unknown

Lunar Landing

A privately owned lunar lander touched down on the moon Thursday, but as the minutes dragged on, flight controllers could not confirm its condition or whether it was even upright near the south pole.

The last time Intuitive Machines landed a spacecraft on the moon, a year ago, it ended up sideways.

The company's newest Athena lander dropped out of lunar orbit as planned, carrying an ice drill, a drone and two rovers for NASA and others. The hourlong descent appeared to go well, but it took a while for Mission Control to confirm touchdown.

“We're on the surface,” reported mission director and co-founder Tim Crain. A few minutes later, he repeated, "It looks like we're down ... We are working to evaluate exactly what our orientation is on the surface.”

Launched last week, Athena was communicating with controllers more than 230,000 miles away and generating solar power, officials said. But nearly a half-hour after touchdown, Crain and his team still were unable to confirm if everything was all right with the 15-foot lander. NASA and Intuitive Machines abruptly ended their live webcast, promising more updates at a news conference later in the afternoon.

“OK team, keep working the problem," Crain urged.

Intuitive Machines last year put the U.S. back on the moon despite its lander tipping on its side.

Another U.S. company Firefly Aerospace on Sunday became the first to achieve complete success with its commercial lunar lander. A vacuum already has collected lunar dirt for analysis and a dust shield has shaken off the abrasive particles that cling to everything.

Intuitive Machines was aiming this time for a mountain plateau just 100 miles from the south pole, much closer than before.

This week's back-to-back moon landings are part of NASA’s commercial lunar delivery program meant to get the space agency’s experiments to the gray, dusty surface and jumpstart business. The commercial landers are also seen as scouts for the astronauts who will follow later this decade under NASA's Artemis program, the successor to Apollo.

NASA officials said before the landing that they knew going in that some of the low-cost missions would fail. But with more private missions to the moon, that increased the number of experiments getting there.

NASA spent tens of millions of dollars on the ice drill and two other instruments riding on Athena, and paid an additional $62 million for the lift. Most of the experiments were from private companies, including the two rovers. The rocket-powered drone came from Intuitive Machines — it's meant to hop into a permanently shadowed crater near the landing site in search of frozen water.

Intuitive Machines' Trent Martin said before the flight that Athena needed to land upright in order for the drone and rovers to deploy.

To lower costs even more, Intuitive Machines shared its SpaceX rocket launch with three spacecraft that went their separate ways. Two of them — NASA’s Lunar Trailblazer and AstroForge’s asteroid-chasing Odin — are in jeopardy.

NASA said this week that Lunar Trailblazer is spinning without radio contact and won’t reach its intended orbit around the moon for science observations. Odin is also silent, with its planned asteroid flyby unlikely.

As for Athena, Intuitive Machines made dozens of repairs and upgrades following the company’s sideways touchdown by its first lander. It still managed to operate briefly, ending America’s moon-landing drought of more than 50 years.

Until then, the U.S. had not landed on the moon since Apollo 17 in 1972. No one else has sent astronauts to the moon, the overriding goal of NASA’s Artemis program. And only four other countries have successfully landed robotic spacecraft on the moon: Russia, China, India and Japan.

Houston scientists make breakthrough in hearing science and treatment research

sounds good

Researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital have successfully mapped which cell populations are responsible for processing different types of sounds.

Working with a team at the Oregon Health & Science University, the Houston scientists have classified where in the cochlear nucleus our brains connect with various sounds, including speech and music. The research was published in the new edition of Nature Communications.

“Understanding these cell types and how they function is essential in advancing treatments for auditory disorders,” Matthew McGinley, assistant professor of neuroscience at Baylor, said in a release. “Think of how muscle cells in the heart are responsible for contraction, while valve cells control blood flow. The auditory brainstem operates in a similar fashion — different cell types respond to distinct aspects of sound.”

Though scientists have long thought that there are distinct types of cells in the cochlear nucleus, they didn’t have tools to distinguish them until now.

Lead author on the study, Xiaolong Jiang, associate professor of neuroscience at Baylor, added: “This study not only confirms many of the cell types we anticipated, but it also unveils entirely new ones, challenging long-standing principles of hearing processing in the brain and offering fresh avenues for therapeutic exploration.”

Jiang and his team have cooked up a comprehensive cellular and molecular atlas of the cochlear nucleus, which will help them to create more targeted and more effective treatments for patients struggling with their hearing.

The strategies that aided them in creating these tools included single-nucleus RNA sequencing, which made it possible to define neuronal populations on a molecular level. Phenotypic categorizations of the cells were made possible with patch sequencing.

This is a watershed moment for the development of targeted treatments for individuals with auditory disorders, including those with impaired function in the auditory nerve, for whom cochlear implants don’t work.

“If we can understand what each cell type is responsible for, and with the identification of new subtypes of cells, doctors can potentially develop treatments that target specific cells with greater accuracy,” McGinley explains. “These findings, thanks to the work of our collaborative team, make a significant step forward in the field of auditory research and get us closer to a more personalized treatment for each patient.”

Houston shines among top 10 tech metros in the South, study says

Tops in Tech

A study analyzing top U.S. locales for the tech industry ranked Houston the No. 9 best tech hub in the South.

The report by commercial real estate platform CommercialCafe examined the top 20 Southern metros across nine metrics, such as the growth rates of tech establishments and employment, median tech earnings, a quality of life index, and more.

Like other Texas metros, the study attributes Houston's tech powerhouse status to its growing presence of major tech companies. However, Houston leads the nation with the highest number of patents granted between 2020 and 2024.

"The second-largest metro by population in the South, Houston led the region with an impressive 8,691 tech patent grants in the last five years," the report said. "Once synonymous with oil, Houston is increasingly making its mark as a cleantech hub — and patents reflect this shift."

Houston also experienced an impressive 14 percent growth in tech establishments, with nearly 500 new tech companies moving to the metro. An impressive 32 percent job growth rate also accompanied this change, with over 30,500 tech jobs added between 2019 and 2023.

Here's how Houston stacked up across the remaining five rankings:
  • No. 11 – Tech establishment density
  • No. 15 – Median tech earnings
  • No. 19 – Median tech earnings growth
  • No. 20 – Tech job density
  • No. 20 – Quality of life index

In a separate 2024 report, Houston was the No. 22 best tech city nationwide, showing that the city is certainly making efforts to improve its friendliness toward the tech industry in 2025.

Other top Texas tech hubs in the South
The only other Texas metros to earn spots in the report were Austin (No. 1) and Dallas-Fort Worth (No. 4). Most notably, CommercialCafe says Austin saw a 25 percent increase in tech company density from 2019 to 2023, which is the third-highest growth rate out of all 20 metros.

"Moreover, the metro’s tech scene thrives on a diverse range of segments, including AI and green energy (bolstered by the University of Texas), as well as globally recognized events like [South by Southwest]," the report says. "Thus, with tech companies accounting for more than half of all office leasing activity in 2024, Austin remains a magnet for innovation, talent and investment."

Dallas, on the other hand, has a far greater diversity when it comes to its tech sector and its thriving economic opportunities.

"Not to be outdone, Dallas-Fort Worth moved up from sixth to fourth in this year’s rankings, driven by a 25.9 percent growth in tech company presence — the second-highest increase among the top 20 metros," the report said. "For instance, companies like iRely (which relocated to Irving, Texas) and Diversified (now in Plano, Texas) have joined homegrown successes, such as StackPath and Bestow."

The top 10 best tech metros in the South are:

  • No. 1 – Washington, D.C.
  • No. 2 – Austin, Texas
  • No. 3 – Raleigh, North Carolina
  • No. 4 – Dallas-Fort Worth, Texas
  • No. 5 – Huntsville, Alabama
  • No. 6 – Baltimore, Maryland
  • No. 7 – Durham, North Carolina
  • No. 8 – Atlanta, Georgia
  • No. 9 – Houston, Texas
  • No. 10 – Charlotte, North Carolina
