[Aortic Valve Replacement and Mitral Valve Plasty in a Patient with Left Ventricular Noncompaction Associated with Aortic Regurgitation and Mitral Regurgitation;Report of a Case].

Left ventricular noncompaction (LVNC) is believed to represent an arrest in the normal process of myocardial compaction, resulting in persistence of both hyper-trabeculation and intra-trabecular recess within the left ventricle. The clinical features of this disease are left ventricular dilatation and systolic dysfunction, which carry a high mortality. Most patients die in infancy, but some cases of LVNC in adults have been reported. To the best of our knowledge, only 4 cases of LVNC with valvular heart disease in adults have recently been operated. We describe a 51-year-old man with LVNC and severe aortic regurgitation and mild mitral regurgitation, who was successfully operated upon with aortic valve replacement using a tissue valve, and mitral valve plasty with bilateral papillary muscle relocation.
