  • Surgical Treatment for Early Left Ventricular Rupture after Mitral Valve Replacement

    Abstract: Objective To investigate the cause, treatment, and prevention strategy of early left ventricular rupture after mitral valve replacement (MVR). Methods We retrospectively analyzed clinical data of 7 patients who had early left ventricular rupture after MVR, among a total of 2 638 MVR patients, between May 1981 and November 2010 in General Hospital of Shenyang Military District. There were 2 male patients and 5 female patients with their age ranging from 28 to 71 years old. One patient was New York Heart Association (NYHA) functional classⅡand 6 patients were NYHA functional classⅢ. Preoperative echocardiography showed that their left ventricular ejection fraction (LVEF) was 49%-60% and their left ventricular end diastolic volume (LVEDV) was 29-42 ml. All the patients underwent prothetic valve replacement under moderate hypothermia, general anesthesia and extracorporeal circulation. Results All the 7patients underwent surgical repair for their early left ventricular rupture. There were 2 patients with TypeⅠ, 4 patients with TypeⅡ, and 1 patient with TypeⅢleft ventricular rupture. Four patients died of hemorrhagic shock or low cardiac output syndrome. Three patients were successfully healed and discharged from hospital 7-15 days after the operation. The 3 surviving patients were followed up for 4.5-18.0 years, and they all had good general condition and satisfactory quality of life. No late pseudo-aneurysm was found during follow-up. Conclusions Early left ventricular rupture is difficult to repair with a high mortality. Effective prevention strategy should be applied to avoid it as much as possible. Once left ventricular rupture occurs during the surgery, extracorporeal circulation should be quickly established, and it’s possible to save patients’ life by reliable intracardiac and epicardial repair according to patients’ individual condition.
