The PREPARE-MVR (PRediction of Early PostoperAtive Right vEntricular failure in Mitral Valve Replacement/Repair patients) Study aims to evaluate those preoperative factors which can predict the early postoperative right ventricular failure or determine the functional shift seen in right ventricular function after mitral valve replacement/repair. The PREPARE-MVR study focuses mainly on echocardiographic (both conventional and advanced) parameters and includes right heart catheterization intraoperatively and in the early postoperative period as gold standard method.

right ventricular failure
Early postoperative right ventricular failure is defined as right ventricular stroke work index \<300 mmHg/mL/m2 measured by right heart catheterization. Late right ventricular failure is defined as \>10% decrease in right ventricular ejection fraction compared to preoperative value measured by 3D echocardiography.
Time frame: From date of operation until the date of first documented right ventricular failure assessed up to 6 months
