Abstract:
Ventricular noncompaction is a rare unclassified cardiomyopathy due to intrauterine arrest of compaction of the loose interwoven meshwork. It is characterized by markedly irregular endocardial surfaces with prominent trabeculations and intertrabecular recesses. Patients are asymptomatic or present with depressed ventricular function, ventricular arrhythmia, and systemic embolism. Areas of restricted myocardial perfusion have been previously documented by scintigraphy and positron emission tomography. This report documents a case of isolated left ventricular noncompaction with subendocardial perfusion deficits on MRI.
