Abstract

To better understand the outcome of the bicuspid aortic valve (BAV) after valve-sparing root replacement, we evaluated BAV function after its preservation at the time of the ascending aorta (AA) repair. From January 1, 1994, through March 31, 2002, BAVs were preserved during repair of AA aneurysms in 21 patients (mean +/- SD age, 45+/-12 years; 13 males). We reviewed the clinical and surgical records of these patients for baseline characteristics, operative procedures, and data at latest follow-up. The primary indication for operation was AA enlargement (median diameter, 55 mm; range, 43-65 mm) in 18 patients and severe aortic regurgitation (AR) in 3 patients. Preoperatively, the BAV exhibited mild or moderate stenosis in 5 patients (mean gradient, 25 mm Hg; range, 19-34 mm Hg), moderate AR in 2, and severe AR in 3. Aortic valve repair was performed in 11 patients. Seventeen patients had excision and graft replacement of the enlarged AA, and 4 patients had primary AA repair. There were no perioperative deaths. Moderate or severe AR was relieved in all patients early postoperatively and during follow-up (median, 2.5 years; maximum, 7.6 years). One patient required aortic valve replacement at 4.8 years for AR. An additional patie...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aortic Coarctation

Aortic coarctation is a congenital condition characterized by narrowing of the aorta. Discover the latest research on this disease here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
