Advanced cardiac care to get you back to those you love

Surgical services

CHI Memorial’s Guerry Heart and Vascular Center performs more open-heart procedures than any other hospital in Chattanooga. Our experience lifts us above the ordinary as skilled surgeons, highly-trained staff, superior technology and patient support services combine for a mind-body-spirit care team that is second to none. All cardiac surgical procedures are performed at CHI Memorial Hospital Chattanooga.

The Coronary Artery Bypass Graft (CABG) to bypass blockage in a coronary artery is the most commonly performed open-heart procedure in the United States. Surgeons use segments of the patient’s own veins and arteries to go around these blockages and deliver blood to the heart. CABGs have an overall success rate of almost 98 percent.

Valve damage is among the most common of heart problems. CHI Memorial offers patients the latest technologies for valve repair and valve replacement with success rates high above national averages. New, minimally-invasive techniques shorten hospital stays and recovery times.

Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure that enables a collapsible aortic heart valve to be placed inside the heart. During the procedure, TAVR device is crimped down and placed into the body via a catheter that is inserted in the upper thigh or groin. Once it’s delivered to the site of the patient’s diseased valve, the device is expanded with a balloon and begins to work immediately.

MitraClip® is a breakthrough technology for people who suffer from mitral valve regurgitation but are too high risk for surgical valve repair or replacement. MitraClip® therapy is the world’s first transcatheter mitral valve repair–meaning no surgical incisions are needed to deliver this lifesaving therapy.

An aortic aneurysm is an abnormal enlargement or bulging of the aorta, the largest blood vessel in the body, due to weakness in the vessel wall. CHI Memorial surgeons are skilled at replacing the weakened section of the thoracic aorta with a synthetic graft or tube to prevent the possibility of rupture and internal bleeding.


CHI Memorial is honored to be one of 48 hospitals in the nation that received a ‘high performing’ rating in all nine surgical procedures and chronic conditions evaluated by U.S. News, including heart failure, heart bypass, aortic valve and AAA Repair.
