CorAccess: Strengthening Heart Tissue

Robert Guyton, MD; Muralidhar Padala, PhD

Minimally invasive heart valve replacement procedures have emerged as an alternative to open-chest heart surgery, allowing smaller incisions, less pain, and faster recovery. Transapical cardiac access is one such procedure where the inner chambers of the heart are accessed by puncturing a hole in the apex of the heart but a frequent problem is the poor mechanical strength of the tissue in this region.

Researchers at Emory have developed a method that strengthens the tissue of the heart apex to increase stability, prevent leakage, and provide a sound channel to the cardiac chambers that can be securely closed after the procedure. "Not all hearts are the same, as far as the mechanical strength of the tissue—in the elderly, or those who don't exercise and have fatty tissues, the tissue is quite weak and normal closure devices like sutures, clamps, screw devices, will not hold," says Robert Guyton, MD, chief of cardiothoracic surgery at Emory University Hospital who, along with Muralidhar Padala, PhD, assistant professor in the Division of Cardiothoracic Surgery, invented the device.
