VIDEO: New LVAD Designed to Prevent Hemolysis and Clots

Surgeons at Penn State Heart and Vascular Institute were the second group in the nation to implant a newly-designed mechanical pump in a patient with severe heart failure. The EvaHeart2 Left Ventricular Assist System (LVAD), can be used as a destination therapy and as a bridge to transplant.

Rob Dowling, M.D., director of heart device research at Penn State Heart and Vascular Institute and Penn State College of Medicine, explains the benefits of the new  LVAD system. He was one of the cardiothoracic surgeons who implanted the pump and said the EvaHeart2 left ventricular assist system was designed to reduce the risk of post-implantation stroke, which affects approximately 8% of heart failure patients implanted with an LVAD.

The flush inflow ostium in the left ventricle, low profile inflow design, rotational apex suture cuff are designed to be forgiving on possible inflow cannula malposition and to minimize the risk of wedge thrombus.

“Imagine inserting the tip of a vacuum cleaner into the left ventricle of the heart to get the blood to the pump and out to the rest of the body,” Dowling said. “Sometimes the tip can move into an incorrect position even after proper surgical placement and can create suction against the walls of the heart. This may create blood clots that could cause strokes. This new device was designed in such a way that there is no tip, but rather the “vacuum” hose itself is surgically attached directly to into the lining of the walls of the heart, removing the need for a tip and thereby potentially reducing the risk of stroke.”

The procedure was part of the COMPETENCE Trial, a multi-center clinical study to evaluate EvaHeart2 that will include 40 clinical sites and 399 patients with severe heart failure through 2022.

Richard Huggins, 75, of Lock Haven, Pa., was the second patient in the nation to receive the EvaHeart2 Left Ventricular Assist System (LVAS). Surgeons at Penn State Heart and Vascular Institute implanted the device on Jan. 13.
