Abstract:
Surgery for functional mitral regurgitation (FMR) and dilated cardiomyopathy (DCM) remains a challenge. We reviewed our efforts;anterior (i.e. physiological) relocation of papillary heads and muscles(PHO) in 54 patients with FMR and simplified ventricular restoration of uni-directional Dor or Frozen-Apex restoration in 22 patients with DCM. Actuarial survival 4 years after the PHO was 92±6% with improved left ventricular (LV) function and well controlled FMR. Results of the simplified restoration was also promising with no hospital death and just 1 cardiac death late postoperatively, with good symptom relieve and maintained LV function. Surgical outcome for FMR or DCM may be further improved.
