This year, Lexington Medical Heart Center will begin offering transcatheter aortic valve replacement, known as TAVR. This state-of-the-art cardiovascular technology allows doctors to replace the aortic valve without open heart surgery.“TAVR is the single most important advance in interventional cardiology since coronary angioplasty,” said Dr. Robert Leonardi of Lexington Cardiology, a Lexington Medical Center physician practice.
He will perform TAVR procedures as part of a highly skilled cardiac care team that includes Dr. Robert Malanuk of Lexington Cardiology and Dr. Jeffrey Travis of Lexington Cardiovascular Surgery, a Lexington Medical Center physician practice, as well as nurses, technicians and a cardiovascular anesthesiologist.
Currently, TAVR is for patients with severe aortic stenosis who are not candidates for open heart surgery because of their age, history of heart disease, or other health issues.
Patients with severe aortic stenosis have a narrowed aortic valve that does not allow blood to flow efficiently. As the heart works harder to pump enough blood through the smaller opening in the valve, the heart eventually becomes weak. Over time, that can lead to life-threatening heart problems.
TAVR offers a less invasive option than open heart surgery. To replace the diseased aortic valve, the new aortic valve is compressed into a tube-like device called a delivery catheter that’s slightly wider than a pencil. Doctors insert the delivery catheter and the new aortic valve into an artery and thread the catheter through the body to the inside of the diseased aortic valve. Then, doctors deploy the new valve from the delivery catheter inside the diseased aortic valve, which becomes the anchor for the new valve. The new valve is functional immediately and normal blood flow is restored.
Lexington Medical Heart Center will use the Edwards SAPIEN Transcatheter Heart Valve. It’s made of bovine tissue with a stainless steel frame. The TAVR procedure takes less than two hours.
“The main benefit is that patients feel better and live longer,” Dr. Leonardi said.
Studies show that TAVR reduces the mortality rate in patients by 20% in the first year after the procedure.
“Patients often want to know if there’s something we can do to make them feel better,” he added. “TAVR allows that to happen.”
