Abstract:
We have utilized the combined techniques of subvalvular annuloplasty and leaflet suspension since 1999 to repair prolapsing aortic valves. We reviewed our short-term results to assess perioperative echocardiographic changes and repair durability. Nineteen patients (15 men and 4 women; mean age, 60.7 years) underwent this operation between July 1999 and June 2002. All were interviewed to establish their latest functional status, reoperation and survival rates. After a mean follow-up of 40.1 months, all patients were alive and in New York Heart Association functional class I. The echocardiographic grade of aortic regurgitation decreased from 3.2 preoperatively to 1.6 at follow-up. Left ventricular end-diastolic dimension shortened significantly from 6.2 to 5.2 cm. Left ventricular end-systolic dimension decreased from 4.1 to 3.3 cm. Annulus size was also significantly less at 2.2 cm from 2.5 cm preoperatively. At 48 months, freedom from reoperation was 88.9% +/- 7.4%. The follow-up was 100% complete. Repair of a prolapsing aortic valve with leaflet suspension and subvalvular annuloplasty is a good procedure and the short-term results are satisfying.
