Abstract

Background The authors performed this retrospective study to report the experience of mitral valve repair (MVR) repair procedures, including the commonly used operative techniques and recorded outcomes. Patients and methods A total of 100 patients (76 males) who underwent MVR were enrolled in this study. Diagnosis was mainly based on detailed history taking along with an echocardiographic assessment. Data on preoperative, intraoperative, and postoperative variables were collected retrospectively from the database and patients' records. Missing data for particular outcomes were removed from the analysis. Results The four observed pathologies of the mitral valve [ischemic (67%), myxomatous (18%), postinfective (11%), and rupture chordae (4%)] were repaired with annuloplasty ring, leaflet dissection and annuloplasty ring, pericardial patch closure ± ring annuloplasty, and artificial chordae replacement, respectively. The preoperative and postoperative stay durations were 6.21 ± 6.318 and 12.19 ± 11.54 days, respectively. Only two deaths were recorded (one within the first 30 days of the procedure and one after). Operative bleeding occurred in four patients (of 98; 4.1%), and four patients (of 98; 4.1%) developed arrhythmia. Ten (of 98; 10.2%) patients were re-admitted into the ICU. Twelve (of 95; 12.6%) patients developed infection. At discharge, no cases of mitral regurgitation were observed. Except for preoperative and postoperative stay durations (which were significantly longer in the ischemic group), other outcomes showed no significant difference between the four used techniques. Conclusion The single-center experience highlights the safety of MVR procedure, but indicates that special caution should be warranted to reduce the incidence of post-operative infections. Except for longer preoperative and postoperative stay durations in the ischemic group, no outcome differences were observed between the used techniques. However, large, multicenter, randomized trials with longer follow-up periods are required to validate these findings.
