Method of Managing the Small Aortic Annulus during Valve Replacement

In a series of 130 patients undergoing aortic valve replacement, 20 had the ascending aorta enlarged with a Dacron patch. Eight of these required division of the annulus with extension of the incision inferiorly to the anterior leaflet of the mitral valve. The resulting separation of the annulus all...

Summary:In a series of 130 patients undergoing aortic valve replacement, 20 had the ascending aorta enlarged with a Dacron patch. Eight of these required division of the annulus with extension of the incision inferiorly to the anterior leaflet of the mitral valve. The resulting separation of the annulus allowed a larger size valve to be inserted. Glutaraldehyde-fixed porcine heterografts were used in all patients having the annulus enlarged. No deaths occurred in those patients having annular enlargement, and the postoperative studies show no evidence of mitral valve dysfunction.
