In 1969, Dr. Denton A. Cooley implanted the first total artificial heart in a living patient. Most Houstonians know Cooley’s name, but fewer can name his colleague, Dr. Domingo Liotta, who created the device. Liotta died last year at the age of 97, but his work continues at the Texas Heart Institute.

Meet Yaxin Wang, PhD. The research engineer leads the IDEA Lab at THI. IDEA stands for Innovative Device & Engineering Applications, an apt description of what Wang and her colleagues do. She’s currently focused intensely on projects that could radically change transplantation for patients in need of an artificial heart or new, healthy lungs.

Specifically, Wang is helping to develop a pediatric left ventricular assist device (NeoVAD) to mechanically pump that part of the heart in infants and small children born with heart defects.

“There aren’t a lot of options for very small kids,” explains Wang. “That’s why we’re working on an implantable LVAD for very young kids.”

In fact, as many as 14,000 children with congenital heart disease are hospitalized each year waiting for a new heart, but only around 500 pediatric transplants actually take place.

Essentially, once patients reach their teens, their chest cavities are large enough for an adult donor heart. But smaller children means smaller rib cages and fewer available hearts. For children born with heart disease, Wang’s LVAD could be a lifesaver. Because she has crafted minimally invasive devices that were developed for long-term use, patients could live far longer than before.

The project, funded by a $2.8 million NIH grant, has a big name attached. Dr. O.H. Frazier is a THI legend who claims to have performed 900 LVAD implantations, not to mention some 1,200 heart transplants. In April, the team published their initial findings regarding the success of and improvements in making rotary LVADs over the last half-century.

A different team, also led by Frazier and Wang, received a pair of grants this summer. That includes $2.8 million from the NIH and a total of $7.8 million from a DoD focused program and a THI sub-award. Their work will center on a novel centrifugal left-ventricular assist device intended for end-stage heart failure patients, a potentially safer alternative to a heart transplant.

But Wang isn’t solely focused on the heart. Working with Dr. Gabriel Loor, a cardiothoracic surgeon at Baylor College of Medicine, Wang is also responsible for a method of preserving the lungs for a longer stretch of time, which would allow for further transport, and in the more distant future, potential genetic modification before transplantation. Using animal models for the moment, “they can survive for several hours without any issues,” says Wang.

The pioneering researcher is well on her way to making a name for herself at the Texas Heart Institute and beyond. And soon, she’ll be saving countless lives.

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 students develop cost-effective glove to treat Parkinson's symptoms

smart glove

Two Rice undergraduate engineering students have developed a non-invasive vibrotactile glove that aims to alleviate the symptoms of Parkinson’s disease through therapeutic vibrations.

Emmie Casey and Tomi Kuye developed the project with support from the Oshman Engineering Design Kitchen (OEDK) and guidance from its director, Maria Oden, and Rice lecturer Heather Bisesti, according to a news release from the university.

The team based the design on research from the Peter Tass Lab at Stanford University, which explored how randomized vibratory stimuli delivered to the fingertips could help rewire misfiring neurons in the brain—a key component of Parkinson’s disease.

Clinical trials from Stanford showed that coordinated reset stimulation from the vibrations helped patients regain motor control and reduced abnormal brain activity. The effects lasted even after users removed the vibrotactile gloves.

Casey and Kuye set out to replicate the breakthrough at a lower cost. Their prototype replaced the expensive motors used in previous designs with motors found in smartphones that create similar tiny vibrations. They then embedded the motors into each fingertip of a wireless glove.

“We wanted to take this breakthrough and make it accessible to people who would never be able to afford an expensive medical device,” Casey said in the release. “We set out to design a glove that delivers the same therapeutic vibrations but at a fraction of the cost.”

Rice’s design also targets the root of the neurological disruption and attempts to retrain the brain. An early prototype was given to a family friend who had an early onset of the disease. According to anecdotal data from Rice, after six months of regularly using the gloves, the user was able to walk unaided.

“We’re not claiming it’s a cure,” Kuye said in the release. “But if it can give people just a little more control, a little more freedom, that’s life-changing.”

Casey and Kuye are working to develop a commercial version of the glove priced at $250. They are taking preorders and hope to release 500 pairs of gloves this fall. They've also published an open-source instruction manual online for others who want to try to build their own glove at home. They have also formed a nonprofit and plan to use a sliding scale price model to help users manage the cost.

“This project exemplifies what we strive for at the OEDK — empowering students to translate cutting-edge research into real-world solutions,” Oden added in the release. “Emmie and Tomi have shown extraordinary initiative and empathy in developing a device that could bring meaningful relief to people living with Parkinson’s, no matter their resources.”

New Austin tower eclipses Houston landmark as Texas' tallest building

Tallest in Texas

Texas officially has a new tallest tower. The title moves from Houston, for the JPMorgan Chase Tower, to Austin, for Waterline at 98 Red River St. The new tower will contain mixed-use spaces including apartments, offices, a hotel, restaurants, and retail. It is scheduled to open in full in 2026.

Waterline held a "topping out" ceremony in August, when the final beam was added to the top of the tower. It now reaches 74 stories and 1,025 feet — just 23 feet taller than the JPMorgan Chase Tower.

According to a press release, hundreds of construction workers and team project members attended the Waterline ceremony, and more than 4,750 people have worked on it since the project broke ground in 2022. An estimated 875 people were working onsite every day at the busiest time for construction.

The Waterline site is on a 3.3-acre campus with lots of views of Waller Creek and Lady Bird Lake. The building contains space for 352 luxury apartments, 700,000 square feet of offices, a hotel called 1 Hotel Austin with 251 rooms, and 24,000 square feet of retail stores and restaurants.

The only space that is open to new tenants already is the office space, with residential soon to follow. The hotel and residential units are expected to open in fall 2026.

“Seamlessly integrated with Waller Creek, Waterloo Greenway and the hike-and-bike trail around Lady Bird Lake, Waterline will quickly become a top downtown destination and activity center," said Lincoln executive vice president Seth Johnston in a press release. Project improvements will also make it far easier for people to access all of the public amenities in this area from Rainey Street, the new Austin Convention Center, and the rest of the Central Business District."
