摘要
Objective: The study objective was to evaluate the midterm results of a technique for correction of posterior leaflet prolapse without resection or use of artificial chordae. %26lt;br%26gt;Methods: From May 2009 to October 2013, 96 patients with isolated posterior leaflet prolapse (n = 36) or bileaflet prolapse (n = 60) with or without chordal rupture underwent posterior leaflet repair at the Prince Sultan Cardiac Center. The novel Uniscallop (%26quot;U%26apos;%26apos;) technique was used in 46 patients (group U), based only on scallop suture without resection or artificial chordae application. A conventional approach (quadrangular or triangular resection, focal sliding, artificial chordae) was adopted in the remaining 50 patients (group C). In both groups, the annulus was reshaped using a 40-or 50-mm-long band. Postoperative echocardiography was performed in all patients after a mean follow-up of 18 +/- 13 months in group U and 20 +/- 9 months in group C. %26lt;br%26gt;Results: There were no early or late deaths. No patients in either group showed systolic anterior motion. Both surgical strategies were successful in obtaining a significant reduction in mitral regurgitation grade. Left ventricular function was maintained, and tricuspid regurgitation grade was reduced overall. Moderate mitral regurgitation during follow-up developed in only 1 patient in group C, as the result of dehiscence of a plication stitch. %26lt;br%26gt;Conclusions: Although the rationale for the use of the U technique is different from what is generally accepted, the midterm results of this approach are comparable to those obtained with more conventional techniques, remaining stable after a mean follow-up of 18 months.
