Abstract

ObjectiveThis study evaluates the early results of our initial experience with aortic annuloplasty using a complete external Dacron band in the setting of type Ic or type II aortic regurgitation (AR).MethodsFrom May 2017 to August 2019, 16 patients (88% bicuspid aortic valves, no patients with connective tissue disorders) underwent aortic annuloplasty with an external complete Dacron band. Clinical and echocardiographic follow-up was 100% complete. Clinical and echocardiographic follow-up averaged 24.4 ± 9.3 and 15.1 ± 8.3 months, respectively.ResultsMean cardiopulmonary and cross-clamp times were 105 ± 15 (72–127) and 86 ± 15 (51–113) min, respectively. Early and late mortality was 0%, with no incidents of endocarditis or cerebrovascular events during the follow-up. Two patients were re-operated during the follow-up, one due recurrent aortic regurgitation (12 months after the first operation) yielding a freedom from reoperation due to AR at 1 year and 3 years of 100% ± 0% and 93.3% ± 5.7%, respectively. Based on the latest echocardiogram, five patients had either none or trivial AR, six had mild AR, and three had mild-to-moderate AR.ConclusionsThe early clinical and echocardiographic results after using a complete external Dacron band are promising; however, more data and longer follow-up are needed to determine its role in annular management during aortic valve repair.

Summary

Introduction

Aortic valve repair has emerged as a surgical alternative to valve replacement in the setting of aortic regurgitation (AR) in selected patients [1]. Several annuloplasty techniques have been described to reduce annular dilatation; external or internal suture annuloplasty, partial band annuloplasty, and complete rigid or flexible ring annuloplasty [5]. All these procedures aim to stabilize the aortic root, and enhance the long-term durability of the aortic valve repair. Lansac and colleagues have advocated the use of an external flexible ring annuloplasty at the subvalvular level to stabilize the aortic root over time [6]. In type Ic or type II AR, we use a self-made complete external Dacron band to the reduce and stabilize the aortic annulus. The aim of this study was to report the early results after aortic annuloplasty with a complete external Dacron band
