Abstract

We reviewed a consecutive series of 90 patients undergoing concomitant resection of ascending aortic anerysm and aortic valve replacement (AVR) utilizing noncomposite "conventional" techniques in order to assess the early and late results, to define limitations of this operative approach, and thereby to clarify the indications for composite reconstruction of the aortic root. Mean age was 55 years. Twenty percent had Marfan's syndrome, and 13% had aortic dissections. The cause of the aneurysm was dissection in 13% of cases, syphilis in 11%, atherosclerosis in 9%, and degeneration (with or without cystic medionecrosis) in 67%. Follow-up averaged 3.8 years and extended to 11.5 years maximum. AVR and complete excision of the aneurysm (preserving small tongues of aortic wall circumscribing the coronary artery ostia) coupled with tubular graft replacement of the ascending aorta were performed. Nineteen percent of patients required individual technical modifications relating to the coronary arteries. Operative mortality rate was 13%, with the majority of deaths being due to cardiac causes. Contemporary (1975 to 1978) operative mortality rate was 4.3%. Seven percent required re-exploration for hemorrhage and 2.4% had perioperative myoc...Continue Reading

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.

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.

Aneurysm

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