Ventricular reshaping with devices.

Device-based left ventricular reshaping to facilitate reverse remodeling in cases of congestive heart failure represents an innovative surgical strategy. Originating from experiences gained with partial left ventriculectomy and dynamic cardiomyoplasty, the Myocor Myosplint device and the Acorn CorCap Cardiac Support Device are intended to improve left ventricle function through left ventricular shape change by means of wall stress reduction and passive diastolic support, respectively. Encouraging experimental and early clinical results with both devices support these novel concepts. Careful patient selection and a combined approach integrating adjunct surgical and medical treatments are crucial factors for the success of ventricular reshaping.
