Internal circular suture annuloplasty for aortic valve repair.

Abstract

Stabilizing the aorto-ventricular junction is integral in aortic valve repair. We report our technique of internal circular suture annuloplasty. We used a continuous horizontal mattress suture of a single thick expanded polytetrafluoroethylene suture (CV-3). We put 4 stitches per sinus, so the suture was below the cusp attachment line at the nadirs and passed through the interleaflet triangle at the upper aorto-ventricular junction level. The suture was reinforced with pericardial pledgets on both sides of each commissure. We used this technique in 12 patients. The diameter of aorto-ventricular junction was reduced from 25 ± 2mm to 22 ± 1mm (n = 11) and was 22 ± 1mm at the latest follow-up (4-74months, median 41, n = 10). In 2 patients with large aorto-ventricular junction (27mm or more), expected annular reduction was not achieved. Our modified technique is simple and seems durable. It may be useful for mild annular dilatation.
