OBJECTIVES: Mitral periprosthetic leakage (PPL) is a serious complication following valve replacement. Conflicting outcomes of surgical treatment have been reported in the presence of multiple previous cardiac operations and associated co-pathological conditions. METHODS: Sixty-five symptomatic patients (37 women, mean age 64.8 years) underwent conventional operations at our hospital from 2006 to 2015. Mitral PPL was the leading surgical indication, although associated procedures were included. Previous transcatheter procedures and leaks involving multiple prostheses were excluded. The median number of past mitral operations was 2 (range 1-5). PPL recurrence was observed in 29% of cases. A previous operation on the aortic or tricuspid valve was performed in 31 patients. RESULTS: Mitral PPL involved one-, two- or three-quarters of the mitral perimeter in 46, 43 and 11% of cases. Prosthetic refixation or replacement was performed in 24 and 41 patients, respectively. Annular reconstruction was necessary in 17% of prosthetic replacements. Associated procedures were performed in 19 patients. The operation was executed through a right minithoracotomy (unclamped aorta) in 20% of patients. In-hospital deaths occurred in 3.1%. After a median follow-up of 60 months, freedom from all-cause mortality was 96.8, 91.5 and 88.8% at 1, 3 and 5 years. Lateral leaks [P = 0.03; hazard ratio (HR) = 4.57, 95% confidence interval (CI): 1.13-18.3] and PPL relapse (P = 0.03; HR = 4.33, 95% CI: 1.12-16.7) were independently associated with death. At follow-up, 4 patients had a >2+ recurrent leak and 2 were reoperated. CONCLUSIONS: A customized conventional mitral reoperation still represents a satisfactory and effective treatment option for PPL and should be considered even in patients with very complex issues.
