Current diagnosis and prescription for the Marfan syndrome: aortic root and valve replacement.
Since 1976, the procedure of choice for patients with Marfan aneurysm of the ascending aorta at this institution has been the Bentall procedure or its modification. One hundred seventy-four Marfan patients have had ascending aortic aneurysm repair with a prosthetic composite graft. An additional four children and two adults have had aortic root replacement with a cryopreserved homograft. Thirty-seven (21%) patients came to operation with an acute or chronic dissection involving the ascending aorta. Thirty-one (17%) patients having aortic root replacement also had mitral valve repair or replacement. The first 86 patients in the series had a hemostatic Bentall wrap constructed; however, in the last 88 patients, the ascending aorta has been transected completely and the aortic wall tacked loosely over the composite graft. It is our preference to construct a direct end-to-side anastomosis of each coronary ostium to the side of the composite graft. In the past, we used the Cabrol interposed graft for low-lying coronary ostia, but currently favor the "button technique" for this procedure. One hundred fifty-six of 180 patients underwent elective root replacement with no hospital mortality. Twenty-four patients underwent urgent or emergency surgery; 17 of these patients with acute dissection or rupture underwent emergency surgery. Two of these patients with rupture died intraoperatively. Therefore, overall hospital mortality among the 180 patients was 1.1%. There have been 14 late deaths among 178 patients discharged from the hospital (7.9%). Five of these late deaths occurred among our first 11 patients operated on between 1976 and 1979. Since 1980, there have been nine late deaths among 167 patients (5.4%).(ABSTRACT TRUNCATED AT 250 WORDS)
