Transient severe mitral regurgitation after mitral valve repair is associated with a poor clinical outcome: A small case series

Abstract

Background: During mitral valve repair, patients with transesophageal echo-detected immediate postoperative systolic anterior motion of the mitral valve (SAM) and mitral regurgitation (MR) are successfully medically managed. They have been shown to do well in a short-term follow-up. However, the long-term outcome has not been investigated. The objective of this project was to investigate the long-term outcome of these patients. Methods: This is an observational, retrospective study of 385 patients who underwent MVR. All cases of SAM and MR in this report were successfully medically managed with conservative therapy preventing the need for immediate surgical reintervention. Patients were divided into two groups based on the severity of MR. Group I had grade ≤ 2 + MR (
