Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

New innovation hub grows with the addition of 6 Houston startups

moving in

The East End Maker Hub in Houston's East End District is growing with the recent addition of six startups.

"All of these companies cite the East End Maker Hub's physical innovation infrastructure, customizable spaces, strategic location, and potential collaborators as motivations for moving their operations into the hub," Patrick Ezzell, president of Urban Partnerships Community Development Corp., one of the hub's creators, says in an April 26 news release. "All are in the process of growing their teams and view Houston and, more specifically, the East End as a key resource for human capital heading into the future."

The companies that recently joined the East End Maker Hub are:

  • Alchemy Industrial. The company is a contract manufacturer that uses advanced technologies to develop industrial products for the medical, renewable energy, and drone sectors. Mush Khan, a British-born entrepreneur, established the startup last year.
  • CarbonATM. Led by Frank Zamarron and a group of former NASA engineers, CarbonATM aims to improve monitoring of ambient air quality with a low-cost portable device.
  • Gbowo Inc. This startup, founded in 2020, seeks to help companies reduce the environmental and financial costs of last-mile deliveries through the use of low-speed electrical vehicles. Ganiu Ladejobi is the founder and CEO.
  • Horizon Aeromarine. Established in 2020, the startup develops software and electronics from unmanned aerial and marine vehicles. Laura Sammons and Denver Hopkins are the founders.
  • Parallax 621. Founded by Benjamin Peters and Phillip Lentz, the Parallax 621 tech think tank develops technology based on theoretical physics research.
  • Polyvascular. The startup, established in 2014, makes a polymer-based heart valve for children with congenital heart disease.

The East End Maker Hub, at 6501 Navigation Blvd., is a collaboration between TXRX Labs and Urban Partnerships Community Development that houses crafters, fabricators, and tech manufacturers. TXRX Labs invested $1.25 million in equity to set up the hub. Urban Partnerships Community Development raised $35.75 million in capital to get the project off the ground.

Houston startup with life-saving innovation receives $2M grant

for the children

A $2 million federal grant will enable Houston-based PolyVascular to launch human trials of what it hails as the first polymer-based heart valve for children.

In conjunction with the grant, Dr. Will Clifton has joined the medical device company as chief operating officer. He will oversee the grant as principal investigator, and will manage the company's operations and R&D. Clifton is president and co-founder of Houston-based Enventure, a medical innovation incubator and education hub. He previously was senior director of medical affairs at Houston-based Procyrion, a clinical-stage medical device company.

PolyVascular's Phase II grant came from the Small Business Innovation Research (SBIR) program, which promotes technological projects.

The PolyVascular heart valve will help treat congenital heart disease affecting more than 1 million around the world. PolyVascular plans to launch clinical trials of the valve in children 5 and over within two years.

"Congenital heart disease remains the most common category of birth defect and a leading cause of childhood death in the developed world," reads a March 30 news release from PolyVascular, founded in 2014.

PolyVascular says the valve can be implanted without surgery, and can avoid the use of valve replacements from humans or animals. Those valve replacements are difficult to find and often don't last too long, leading to frequent follow-up surgeries.

"Our aim at PolyVascular is to transform the care of children with congenital heart disease by developing an entirely new generation of valves made of medical-grade polymer devoid of any biological tissue," Dr. Henri Justino, chief medical officer at PolyVascular, says in a release. "The valves in use so far for children have been made of biological tissue. Unfortunately, our immune systems target and destroy this biological tissue, sometimes rapidly, rendering the valve ineffective."

The SBIR grant isn't the only win for PolyVascular in recent years.

In 2019, the startup came away with several honors in the 2019 Texas A&M New Ventures Competition. It won the pitch competition (complete with a $5,000 cash award), and received the Biotex Investment Prize, Amerra Visualization Services Prize, and GOOSE Society Investment Prize.

Also in 2019, PolyVascular, a member of TMCx's 2017 medical device cohort, won in the medical device and health disparities and equity categories at the fifth annual Impact Pediatric Health pitch competition. Additionally, the Southwest National Pediatric Device Consortium granted the company up to $25,000.

Last year, MedTech Innovator, a nonprofit accelerator in the medical technology sector, announced PolyVascular was one of 50 companies chosen to participate in the organization's flagship four-month accelerator program.

"During these uncertain and challenging times, the need for health innovations — specifically those that promise to deliver long-term value to the health care system and patients — is more critical than ever," said Paul Grand, CEO of MedTech Innovator.

Another Houston startup, Vivante Health, also was picked for the MedTech Innovator program. Vivante is a digital health company that helps people address digestive health and wellness.

Two Houston companies are walking away from SXSW with awards and grant funds.

PolyVascular, a member of TMCx's 2017 medical device cohort, won the fifth annual Impact Pediatric Health pitch competition's medical device and health disparities and equity categories. Additionally, the Southwest National Pediatric Device Consortium granted the company up to $25,000.

PolyVascular co-founder Henri Justino represented his company in three-minute pitch, and team members Dan Harrington and Kwon Soo Chun were also in attendance.

The company was one of 12 finalists in the competition, which took place on March 8 at SXSW in Austin. Among the judges was Houston doctor, Chester Koh, professor of urology, pediatrics, and OB/GYN at Baylor College of Medicine and Pediatric Urologist at Texas Children's Hospital.

"At the Southwest National Pediatric Device Consortium, we are always looking for the next cutting-edge breakthrough in the world of medical devices," says Koh in a release. "Impact Pediatric Health's reputation for bringing together the leaders in pediatric medical technology innovations makes it the perfect venue to help identify and accelerate the next generation of medical device companies impacting our youngest of patients."

Founded in 2014, PolyVascular produces polymeric transcatheter valves for children with congenital heart disease — the most common birth defect and number one cause of infant mortality in the developed world. The company's goal is to reduce that number of infant deaths by introducing a higher quality of valves.

Meanwhile, VastBiome, a 2018 biodesign TMCx company, received a $1,000 grant and is now one of two finalists for the San Francisco-based Illumina Accelerator program. The company works with scientists with ongoing clinical trials focusing on the microbiome as it pertains to therapy.

Another TMCx company, Zibrio, was up for an award in the 2019 SXSW Pitch event, but left the contest empty handed.

TMCx has multiple representatives at the festival, and the organization partnered with Energizing Health to host events throughout the first weekend of the conference.

Rice lands $15M U.S. Army award to launch next-gen wireless research center

defense funding

The U.S. Army Research Office has awarded Rice University $15 million to establish a new center for next-generation sensing and communications.

The five-year research center—dubbed the Center for Large Aperture Secure Sensing, Imaging and Communications (CLASSIC)—will unite researchers from universities and national laboratories to develop advanced antenna technologies for future wireless systems. Edward Knightly, the Sheafor-Lindsay Professor of Electrical and Computer Engineering at Rice, will lead the center that “combines expertise in wireless networking, antennas, radar, artificial intelligence, circuits and physics to address growing demands on wireless systems,” according to Rice.

“The challenges we’re tackling require advances that span physics, hardware, communications and computing," Knightly said in a news release. “By combining those strengths in a single center, we can accelerate the development and demonstration of technologies that would not be possible through individual efforts alone.”

Joining Knightly will be Ashutosh Sabharwal of Rice, Sensen Li of the University of Texas at Austin, Hou-Tong Chen of Los Alamos National Laboratory, Danijela Cabric of UCLA, Josep M. Jornet and Tommaso Melodia of Northeastern University, Daniel M. Mittleman of Brown University, and Willie Padilla of Duke University.

Industry partners include Booz Allen Hamilton, Intel, Keysight, Lockheed Martin, MITRE, Northrop Grumman, Qualcomm and Raytheon.

CLASSIC researchers will investigate how large-scale antenna arrays (ELSAAs) can expand the capabilities of wireless systems where technology is limited.

ELSAAs use thousands of coordinated antenna elements to direct radio waves. Researchers aim to develop ways to use the technology to help maintain steady communication when signals are blocked or disrupted and to detect and generate detailed images of concealed objects.

Along with ELSAAs, the center will work to develop sensing techniques for threat detection, study wireless jamming and build resilient high-speed wireless networks. Researchers will ultimately validate the technology in labs and via drone-based field trials.

CLASSIC will also work on developing an AI-driven modeling framework that will simulate complex electromagnetic environments in real time.

“This award demonstrates Rice’s leadership in tackling complex national research challenges through collaboration across disciplines and institutions,” David Sholl, executive vice president for research at Rice, added in the release.

UH scores $18M NIH grant for chronic disease research

research funding

The University of Houston has received a coveted $18.8 million grant from the National Institutes of Health to launch a program to address the root causes of chronic disease.

Only 22 institutions nationwide receive this NIH award, and the 5-year process aligns with the newly established UH Health’s mission to expand healthcare innovations in Texas and beyond. The initiative will be housed in the UH Population Health department.

"This generous funding allows us to directly confront the root causes of chronic illness that place a heavy burden on so many families," Dr. Jonathan McCullers, vice president for health affairs at UH, said in a news release. "With the recent launch of UH Health, we have an unprecedented opportunity to translate scientific discovery into healthier outcomes for our communities by bringing together experts from across the university to improve health where it matters most.”

Through the program, UH researchers from different areas of expertise will work together to address the challenges of chronic illness by looking at biological, social and behavioral factors.

According to the university, chronic diseases like heart disease, diabetes, strokes and others are the leading cause of illness, disability and death in the U.S. They account for 90 percent of the nation’s $5.3 trillion in annual healthcare spending.

Bettina Beech, chief of population health and translational science at UH, serves as principal investigator for the program.

“Chronic disease management largely happens during the 8,700 hours each year that people are not visiting their healthcare provider,” Beech added in the news release. “While healthcare is indispensable, it only accounts for 20 percent of how health is created — genetics accounts for another 10 percent, and the other 70 percent is determined by behavior, social conditions and environment.”

With the funds from the grant, UH will also be able to expand research infrastructure, add to community partnerships, support complementary research, and invest in early-career investigators, according to the news release. UH also aims to develop solutions that could help ease the economic burden of chronic disease.

Report: Where Texas ranks among best and worst states to live in 2026

Texas Talk

After earning its worst-ever ranking last year, Texas has improved slightly on an evaluation of the best states to live, but it's still at the bottom of the pack.

Each year, WalletHub's analysts compare all 50 states using 51 livability metrics to measure their affordability, economy, education and health, quality of life, and safety. Factors that were weighed include the cost of living, homeownership rates, population and income growth rates, wealth gaps, public school system quality, road quality, crime rates, and many others.

The Lone Star State landed at No. 36 in 2026, making it the 15th worth state to live right now. That's on par with its 2024 ranking, and it's a two-spot improvement over its 2025 performance.

While Texas residents can brag about living in a state with the No. 1 highest number of restaurants per capita and the 7th best quality of life in the country, that's about it. Texas earned middling-to-poor scores among the four remaining livability rankings: safety (No. 33), affordability (No. 35), economy (No. 37), and education and health (No. 40).

Here's how Texas fared in other nationwide rankings in the study:

  • No. 27 – Income Growth
  • No. 30 – Housing Costs
  • No. 39 – Percentage of Population in Poverty
  • No. 42 – Percentage of Adults in Fair or Poor Health
  • No. 46 – Homeownership Rate
  • No. 49 – Percentage of Population Aged 25 and Older with a High School Diploma or Higher
  • No. 48 – Average Weekly Work Hours
  • No. 50 – Percentage of Insured Population

Texas has a lot of work to do to improve its livability for all of its residents, but especially for women, according to several other 2026 WalletHub studies. Texas is the fourth-worst state for women, the ninth-worst state for working mothers, and the seventh-worst place to have a baby based on limited access to maternal and pediatric healthcare.

At the very bottom of the report is New Mexico, ranking 50th overall, with Louisiana (No. 49), Mississippi (No. 48), Alaska (No. 47), and Arkansas (No. 46) rounding out the bottom five.

After holding on as the No. 1 best state to live for a few years in a row, Massachusetts now ranks No. 4 and was overtaken by Idaho (No. 1), New Jersey (No. 2), and Wisconsin (No. 3). New Hampshire rounds out the top five best states to live.

WalletHub's top 10 best states to live in 2026 are:

  • No. 1 – Idaho
  • No. 2 – New Jersey
  • No. 3 – Wisconsin
  • No. 4 – Massachusetts
  • No. 5 – New Hampshire
  • No. 6 – Wyoming
  • No. 7 – Utah
  • No. 8 – Minnesota
  • No. 9 – Pennsylvania
  • No. 10 – Florida
