Henry Mayo Newhall Hospital Launches a TAVR Program

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 the most common type of heart disease in the elderly.1 More than 1 in 8 people over the age of 75 have moderate to severe valvular heart disease.2 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 (ie. 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).

“TAVR is a milestone addition to the cardiovascular treatments we offer here,” said Rosella Dolan, RN, Cardiovascular Services nurse navigator at Henry Mayo. “We are very pleased to bring this life-changing procedure to our community.”

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.

While TAVR was initially approved for high surgical risk patients (2011), approval in intermediate (2016) and low risk individuals (2019) soon followed after additional clinical trials demonstrated that TAVR has several benefits over SAVR in these patient populations. The benefits shown in the low risk Edwards Sapien 3 valve trial (PARTNER 3) include decreased mortality and stroke (at one year), shorter hospital stay (three days vs seven days), improved quality of life, and decreased rehospitalizations. As a result, TAVR is now the most common method to replace the aortic valve.

To determine whether an individual is a candidate for TAVR, they need to undergo a comprehensive evaluation by a multidisciplinary Heart Valve Team.  A collaborative effort is led by Interventional Cardiologist Abhishek Sinha, MD, (Henry Mayo’s Structural Heart Director) and Cardiothoracic Surgeon Raffi Kotoyan, MD, who have years of experience with the TAVR procedure. The Henry Mayo Roberta G. Veloz Cardiac Cath Lab already 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).
