ABOUT THE CO-DIRECTOR:
Dr. R. David Fish, a highly respected interventional cardiologist and leader at THI, is co-director of the Center for Heart Valve Disease. Dr. Fish also is director of Interventional Cardiology Research and Education at THI, with special interests in interventional cardiology, coronary and peripheral vascular stents, cardiac electrophysiology, and pacemakers.
For many years valvular heart disease (VHD) has been relegated to the back burner of cardiac diseases while heart attacks, heart failure and arrhythmia held center stage. However, in the past decade, interest in VHD has increased several fold, spurred by a rising incidence of the diseases fueled by an aging US population (VHD increases with age) and by exciting new therapies for VHD. The Texas Heart Institute is strategically positioned to become one of, and perhaps the
most prominent center for the treatment of VHD in the country.
The new Center for Heart Valve Disease focuses on all aspects of valvular heart disease, including improved replacement procedures with less invasive technology and the use of adult stem cell therapy.
Understanding Heart Valve Disease
Valvular heart disease is often seen as an affliction of the elderly and experts anticipate that as the general population ages, including millions of Baby Boomers, and people are living longer, the prevalence and costs of treating these afflictions will significantly rise. The disease, however, can afflict people at any age, and is sometimes congenital.
In addition, researchers worry that the disease often goes undiagnosed and that incidence rates might even be higher than reported. A study recently presented to the American Heart Association looked at patients in New York State and found that the incidences of hospitalization and treatment for heart valve disease have "progressively and constantly risen since the early 1980s," increasing at a rate of almost 10% per year.
VHD is a group of mechanical diseases that impose an overload on the heart that eventually destroys it. These mechanical problems have only a mechanical solution—correction of the lesion by valve repair or replacement.
Such correction has traditionally occurred in the operating room (OR), but new percutaneous (through the skin without surgery) approaches make correction feasible in the catheterization laboratory or in a hybrid OR for some patients. Percutaneous therapy has terrific appeal to patients who can benefit from it without the need for surgery. However, surgery is a proven commodity that produces extraordinary success. Weighing the best therapy for each patient will be a challenge for decades to come.
See the related topics on this website in the Heart Information Center:
Remarkably little is known about why the patient with VHD gets into trouble. What is it about the overload that causes the heart to fail? Such knowledge could lead to better timing of intervention before any adverse affects develop and could potentially lead to new therapeutic targets.

Artificial Heart Valve Carries Very Low Risk of Stroke, Study Says
A landmark artificial heart valve trial that included patients from Texas Heart Institute
showed positive results for those diagnosed with aortic stenosis, a
condition in which the aortic valve stiffens and fails to open properly.
The clinical trial evaluated the CoreValve System, an artificial heart
valve and nonsurgical delivery system made by Medtronic.

Artificial Heart Valve Undergoes Testing
Two great-grandmothers (Anna Jean Irwin, left, and Ana Riddel) share more than a first name after both underwent a unique procedure at THI to correct a life-threatening heart valve condition, severe aortic stenosis. Cardiologists Biswajit Kar, MD and Pranav Loyalka, MD, and cardiovascular surgeon Joseph Coselli, MD, implanted an artificial heart valve in each woman using a non-surgical technique.

Heart doctors praise new valve procedure
"Houston doctors have begun replacing worn-out heart valves without cracking open the patient's chest, an experimental procedure that could open treatment to roughly 100,000 Americans a year now considered too frail to have surgery." Dr. Biswajit Kar, THI cardiologist, discusses the benefits of the procedure and Dr. Blase Carabello, recently named director of THI's Center for Heart Valve Disease, calls it a "huge advance."
