TAVR at Henry Mayo Newhall Hospital
Henry Mayo Newhall Hospital is now offering Transcatheter Aortic Valve Replacement (TAVR), a cutting-edge minimally-invasive procedure (usually percutaneous) to replace narrowed aortic valves that fail to properly open.
Aortic stenosis is commonly caused by the accumulation of calcium on the valve, causing it to harden and restricting its movement. Once a patient with severe aortic stenosis develops symptoms (I.E. shortness of breath), they will have decreased survival unless it is treated. Mortality from severe symptomatic aortic stenosis is approximately 25% at 1 year, and 50% at 2 years. Because of this, timely medical intervention is critical. Historically this was only done surgically by opening the chest, but with advancements in technology and medical practice, this can be done minimally invasively with a transcatheter aortic valve replacement (TAVR).
Who Should get TAVR?
- Aortic stenosis is the most common type of heart disease in the elderly.
- More than 1 in 8 people over the age of 75 have moderate to severe valvular heart disease.
How does TAVR work?
- Surgical valve replacement (SAVR) typically requires an open-heart procedure with a “sternotomy”, in which the chest is opened for the procedure. However, with the TAVR procedure, a hybrid team consisting of a highly trained interventional cardiologist and cardiothoracic surgeon gain access to the heart through the blood vessels.
- Using wires and hollow tubes called catheters, the team guides a new valve across the opening of the diseased valve. The new valve is expanded into place, pushes the diseased valve aside, and uses it to secure itself in place. By restoring the structure and unrestricted movement of the valve, the function of the valve is restored.
TAVR at Henry Mayo
- To determine whether an individual is a candidate for TAVR, they need to undergo a comprehensive evaluation by a multidisciplinary Heart Valve Team. Led by a collaborative effort by Interventional Cardiology (Dr. Abhishek Sinha, MD, Structural Heart Director) and Cardiothoracic Surgery (Dr. Raffi Kotoyan, MD), the Henry Mayo Heart Valve team has years of experience with the TAVR procedure.
- The Henry Mayo cath lab has a track record of proven excellence in structural heart interventions (Patent Foramen Ovale Closure, since 2019) and recently received additional recognition for excellence in treatment of acute myocardial infarctions (STEMIs).
