Abstract
Since there is little information regarding the competency of aortic ball valve prosthesis, aortic root cineangiography was performed in 21 consecutive survivors of aortic valve replacement with a Starr-Edwards valve. Significant leaks around the rim of the prosthesis were recorded in 9 patients 8 of whom had at least Grade II/VI aortic diastolic murmurs. In 4 reoperated patients, this leak was confirmed to be secondary to disruption of suture material, usually in patients with heavily calcified annuli. Since hemodynamic findings may be normal, cineangiographic studies are necessary for complete postoperative evaluation of prosthetic valves.
