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 scores $120M in new cancer research and prevention grants

cancer funding

The Cancer Prevention and Research Institute of Texas has granted more than $120 million to Houston organizations and companies as part of 73 new awards issued statewide.

The funds are part of nearly $154 million approved by the CPRIT's governing board earlier this month, bringing the organization's total investment in cancer prevention and research to more than $4 billion since its inception.

“Today marks an important milestone for CPRIT and for every Texan affected by cancer,” CEO Kristen Doyle said in a news release. “Texas has invested $4 billion in the fight against one of the world’s greatest public health challenges. Over 16 years, that support has helped Texas lead the search for breakthrough treatments, develop new cancer-fighting drugs and devices, and—most importantly—save tens of thousands of lives through early cancer detection and prevention. Every Texan should know this effort matters, and we’re not finished yet. Together, we will conquer cancer.”

A portion of the funding will go toward recruiting leading cancer researchers to Houston. CPRIT granted $5 million to bring John Quackenbush to Baylor College of Medicine. Quackenbush comes from the Harvard T.H. Chan School of Public Health and is an expert in computational and systems biology. His research focuses on complex genomic data to understand cancer and develop targeted therapies.

The University of Texas M.D. Anderson Cancer Center also received $3 million to recruit Irfan Asangani, an associate professor at the University of Pennsylvania Perelman School of Medicine. His research focuses on how chromatin structure and epigenetic regulation drive the development and progression of cancer, especially prostate cancer.

Other funds will go towards research on a rare, aggressive kidney cancer that impacts children and young adults; screening programs for breast and cervical cancer; and diagnostic technology.

In total, cancer grants were given to:

  • The University of Texas M.D. Anderson Cancer Center: $29.02 million
