BACKGROUND: Dilated cardiomyopathy (
DCM) is a life-threatening heart muscle disease characterized by progressive heart failure, which often requires left ventricular assist device (LVAD) implantation or heart transplantation (HTx). A tissue engineering strategy using cell sheets for end-stage heart failure has emerged in recent years.
METHODS: Here, we describe a 50-year-old
DCM patient with severe symptoms of heart failure with severe mitral regurgitation (MR) who was not a candidate for LVAD or HTx. The patient underwent mitral valve replacement followed by the transplantation of autologous myoblast sheets.
CONCLUSIONS: The patient\'s clinical symptoms improved with a preservation of cardiac performance, and he has survived for over 6 years since the combined surgery. This combined method was feasible and appeared to be effective, and thus represents a promising strategy for treating severe heart failure in end-stage
DCM and as an alternative treatment for selected patients who are not candidates for LVAD or HTx.
