Abstract:
Background: We previously reported our experience with an aortic valve plasty (AVP) technique for repairing a stenotic aortic valve. We investigated the feasibility of AVP in patients with aortic regurgitation (AR). Method: Ninety patients underwent aortic valve plasty using a pericardial patch. Patients characteristics of the patients were as follows: mean age; 68 ± 12 years; the left ventricular ejection fraction, 56 ± 12%; and the left ventricular end-diastolic dimension, 58.1 ± 5.8 mm. Transesophageal and transthoracic echocardiography were performed up to three year after the operation. Results: There was no postoperative AR in 81 patients and trivial postoperative AR in 9 patients. The peak systolic pressure gradient across the aortic valve was 14.5 ± 5.6 mm Hg after valve plasty. No patient underwent reoperation for any reason. Peak systolic gradient was significantly lower in aortic valve plasty group compared with aortic valve replacement group using biosprosthetic valve with or without stent (14.5±5.6 vs 28.6±10.2, respectively, p 〈 0.001).The peak systolic gradient was 13.0 ± 7.1 mm Hg after two year. Up to three years later, there was no significant increase in the peak systolic gradient or significant worseningin AR (Figure). Conclusion: Aortic valve plasty using an autologous pericardial patch to treat aortic regurgitation is safe and feasible
