ABSTRACT

Composite replacement is the standard approach for repair of acute type A aortic dissection involving the aortic root. Reimplantation or remodeling procedures have become valve-sparing alternatives. We developed a new and simple technique to stabilize the aortic root. A Dacron graft is attached outside the native aortic cylinder, and incised twice vertically to create openings corresponding to the right and left coronary ostia. Thus the entire graft covers the native aortic root cylinder from the outside, and the native aortic valve and coronary ostia do not need to be reimplanted. From 2002 to 2007, this technique was applied in 14 patients (8 male) with a mean age of 71 years (range, 34–83 years). Four patients died within 30 days; 3 had been hemodynamically unstable with ventilator and inotropic support preoperatively. Echocardiography showed normal function of the preserved aortic valve, without regurgitation, in all patients. This technique is an alternative valve-sparing method for stabilization of the aortic root in patients with acute type A aortic dissection.
