Abstract

Background and aim of the study: In 2009 our group described a new surgical technique for patients with severe mitral valve calcification undergoing mitral valve surgery. This technique creates a new mitral annulus with plication of the mitral leaflet and the atrial wall. Our objective is to report the long-term results of the experience at our institution.

Materials, methods, and results: From 2007 to 2016, a total of 18 patients (mean age 70.5 ± 7.8 years) underwent mitral valve replacement at our institution with this technique. One patient died on the second postoperative day. Clinical and echocardiographic in-hospital and long-term follow-up (55.5 ± 40.4 months) were performed on all the remaining 17 patients. Functional improvement was achieved in all patients. Two patients died 6 and 8 years after surgery (cancer and hemorrhagic stroke). No prosthetic dysfunction, periprosthetic leak, or annular dehiscence were detected in the long-term echocardiographic examinations.

Conclusions: The reconstruction of the mitral annulus by using our technique in patients with severe calcification of the mitral annulus has low long-term mortality, good functional results, and a lack of prosthetic complications.
