Miniaturized assist devices giving hope to more heart failure patients

Dr. Pal is a member of UT Medicine San Antonio, the multispecialty practice of physicians in the Health Science Center’s School of Medicine. Extensively trained at Duke University, the University of California, San Francisco and the Chicago Medical School, Dr. Pal specializes in heart and lung transplantation, VAD implantation, surgery for heart failure, coronary revascularization and valve surgery. He has operating privileges at University Hospital, CHRISTUS Santa Rosa Health Care and the South Texas Veterans Health Care System. With his arrival, San Antonio now has a specialty-trained heart transplant surgeon with extensive experience with mechanical circulatory support.

Ventricular assist devices have come a long way since the first model gained U.S. Food & Drug Administration (FDA) approval in 1994. VADs now are available to a wider range of patients, not only those who need a short-term bridge to transplant but also those for whom a VAD will be the sole means to provide improved, long-term cardiac function. The VAD is called “destination therapy” for these patients.

In January the FDA gave the green light for HeartMate II, a second-generation VAD, to be used in this acutely ill population. HeartMate II is a continuous-flow, left ventricular assist system that is implanted just below the heart to provide mechanical circulatory support, according to an FDA press release. The system is powered by an electrical cable that passes through the skin to a controller worn around the waist.

The FDA action came after a multicenter study found that HeartMate II significantly improved survival and decreased complication rates when compared to earlier-generation devices.

“The FDA approval of HeartMate II is significant for multiple reasons,” Dr. Pal said. “First, it confirms the safety and efficacy of this device in the treatment of advanced heart failure for extended periods in patients who are not eligible for heart transplantation. Second, it provides a proven treatment option for many patients who have significant limitations in quality of life due to heart failure. The new approval allows us to provide this lifesaving treatment to a new population of patients who were previously not candidates for mechanical circulatory support.”

For more information about this therapy, including patient eligibility, please call the cardiothoracic surgery group of UT Medicine San Antonio at (210) 358-8001.

The University of Texas Health Science Center at San Antonio, one of the country’s leading health sciences universities, ranks in the top 2 percent of all U.S. institutions receiving federal funding. Research and other sponsored program activity totaled a record $259 million in fiscal year 2009. The university’s schools of medicine, nursing, dentistry, health professions and graduate biomedical sciences have produced 27,000 graduates. The $753 million operating budget supports six campuses in San Antonio, Laredo, Harlingen and Edinburg. For more information on the many ways “We make lives better®,” visitwww.uthscsa.edu.
