Virginia Mason Introduces TAVR Minimally Invasive Heart Valve Surgery
SEATTLE – (Nov. 14, 2014) – Virginia Mason has added transcatheter aortic valve replacement (TAVR), a minimally invasive alternative to open-heart surgery, to its array of advanced cardiac procedures.
TAVR is an option for patients with severe aortic stenosis (a narrowing of the heart valve opening that can cause heart failure) for whom traditional open-chest surgery is too risky because of their health status or other factors.
“Patients with aortic stenosis often are elderly and have other medical problems,” said cardiologist Drew Baldwin, MD, of the Virginia Mason Heart Institute. “Certain patients may be at high risk for complications if they have open-heart surgery to replace the aortic valve, so TAVR may be a better option for them.”
This potentially life-saving procedure is performed with general anesthesia in the hybrid suite of the new Virginia Mason Surgery Center that opened in September. The hybrid operating room features both catheterization and surgical capabilities. There, interventional cardiologists, heart surgeons, cardiac anesthesiologists and imaging specialists work together during the TAVR procedure, utilizing fluoroscopy and echocardiography as they guide the replacement valve into place.
TAVR is performed on a beating heart and does not require cardiopulmonary bypass. It uses one of two minimally invasive approaches, allowing the cardiologist or surgeon to choose the approach that provides the best and safest way to access the patient’s damaged valve: Entering through the femoral artery (large artery in the groin) or entering through a small incision in the chest. During the procedure, a compressed-tissue heart valve is placed on a balloon catheter and positioned directly inside the weakened aortic valve. Once in position, the balloon inflates and secures the new valve in place. The replacement valve is supported with a metal stent.
The potential benefits of TAVR include shorter hospital stays and faster recovery from surgery, Dr. Baldwin said. A patient may remain in the hospital for up to three weeks following traditional open-heart surgery to repair a heart valve. By comparison, TAVR patients often go home within a few days.
