We specialize in the treatment of the following conditions and diseases:
Aortic Valve Disease
We offer a range of treatment options for aortic valve disease, including balloon aortic valvuloplasty and transcatheter aortic valve replacement (TAVR) with innovative TAVR platforms, in addition to conventional surgical aortic valve replacement. We are able to treat patients with native aortic valve disease as well as patients who have a problem with a previously implanted surgical aortic valve. Our team is very experienced, having performed nearly 1000 TAVR procedures since 2011. In addition, we have participated in many of the pivotal clinical trials of TAVR valves, and we are currently participating in a clinical study for patients at low surgical risk.
Mitral Valve Disease
In addition to conventional open and minimally invasive surgical mitral valve replacement and repair, we specialize in the care of patients at higher risk for mitral valve surgery. We offer balloon mitral valvuloplasty, transcatheter mitral valve repair with a sophisticated MitraClip system, and transcatheter replacement of dysfunctional surgical mitral valves or mitral rings with innovative trancatheter valves. We are also participating in the clinical trial of a new transcatheter mitral valve replacement system.
Paravalvular Leak Closure
Occasionally, valves that are surgically implanted can develop leaking in the area next to but outside the valve. This is known as a “paravalvular leak.” When this causes symptoms or other problems, surgical closure of the leak is sometimes required. In certain situations, we can provide a minimally invasive alternative to surgery by placing a small device to seal the leak.
Prevention of Stroke in Atrial Fibrillation
Most patients with atrial fibrillation have an increased risk of stroke, and many take a blood thinning medication to reduce their risk. For various reasons (e.g., frequent bleeding), some patients are not able to take a blood thinner. Since approximately 90 percent of strokes due to atrial fibrillation involve a clot forming in the left atrial appendage, we offer several procedures to modify the left atrial appendage and therefore reduce the risk of stroke, including transcatheter implantation of the WATCHMAN™ left atrial appendage closure device.
Atrial Septal Defects and Patent Foramen Ovale
The foramen ovale is a connection between the top two chambers of the heart (the left and right atria) which normally closes shortly after birth. Approximately 25 percent of the population in the United States has a patent foramen ovale (PFO), meaning that this connection did not completely close. Younger patients who suffer a stroke or transient ischemic attack without a clear cause, and are found to have a PFO, can be considered for a transcatheter procedure to close the PFO. This procedure may prevent future strokes related to the PFO.
Larger defects in the atrial septum, called atrial septal defects (ASDs), can cause enlargement of the heart, elevated pressure in the lungs, and symptoms including shortness of breath and swelling of the ankles. We offer minimally invasive transcatheter ASD closure to many patients.
Some patients with hypertrophic cardiomyopathy develop abnormal thickening of the heart muscle, which limits the heart’s ability to pump blood to the rest of the body, especially during physical activity. This can cause symptoms including shortness of breath and chest discomfort or even fainting spells. For selected patients who have not had adequate relief of their symptoms with medications, we offer alcohol septal ablation, a minimally invasive catheter-based procedure, as a way to improve symptoms.
