Abstract:
A 46-year-old woman was admitted to our hospital because of progressive exertional dyspnea and occasional premature ventricular contraction. An enhanced computed tomographic scan revealed partial defect of the left ventricular myocardium and prominent trabecular meshwork at the same thin-wall segment. She underwent resection and endoventricular patch plasty using cardiopulmonary bypass. Histopathologic examination showed transmural fibro-fatty replacement of the myocardium, with an extremely thickened endocardium. Here we report an extremely rare case of surgery in a patient with arrhythmogenic left ventricular cardiomyopathy associated with left ventricular noncompaction.
