Background: Mitral repair has been widely used in the treatment of secondary mitral lesions in recent years. Hemolytic anemia is known to be a rare complication after mitral repair. This study aimed to investigate the diagnosis and treatment of mechanical hemolysis after mitral repair in adults.Methods: In this retrospective study, we reviewed the medical records of patients undergoing mitral repair complicated with mechanical hemolysis at our institution between August 2006 and May 2020.Results: Twenty-four patients undergoing mitral repair complicated with mechanical hemolysis were included in the study. They were divided into two groups: the reoperation group (patients who underwent reoperation; N = 18) and the conservative treatment group (patients who received symptomatic treatments, including blood transfusion, diuresis, alkalization of urine, liver protection, hemodialysis, and oral metoprolol; N = 6. All patients in the reoperation group underwent mitral valve replacement. There were six hospital deaths, all in the conservative treatment group. Seventeen of eighteen patients (94.4%) completed follow up. Fifteen of seventeen survivors (88.2%) were in NYHA class I and 11.8% (2/17) in NYHA class II at the last time follow up.Conclusions: Hemolysis is a sign of failure of mitral repair. Reoperation is the best choice once the hemolysis has been diagnosed. Reoperation should be carried out as soon as possible.
