Surgical ventricular restoration is designed to normalize ventricular shape and volume. However, the STICH (Surgical Treatment for Ischemic Heart Failure Trial) found no difference in clinical benefit between CABG and CABG+SVR. It was speculated that improved ejection fraction was balanced by worsened diastolic function. Ventricular 3D flow provides comprehensive assessment of ventricular diastolic and systolic function. In this study, we are aiming to assess 3D flow in an end-stage heart failure patient before and 4-month after SVR using the combined advanced MRI and CFD.
