Acute Kidney Infarction Due to Left Ventricular Thrombus Embolization In Patient with Isolated Left Ventricular Noncompaction: A Case Report
Noncompaction of the ventricular myocardium (NVM) is a rare congenital cardiomyopathy that is characterized by multiple prominent trabeculations and deep intertrabecular recesses, and occurs due to arrest of normal embryogenesis of the endocardium and myocardium. It is also referred to as isolated left ventricular noncompaction (LVNC), because lesions are mainly in the left ventricle. The main clinical manifestations are heart failure, arrhythmia, systemic embolism, and sudden death. Systemic embolism is related to the occurrence of atrial arrhythmias or thrombus formation in the left ventricle. Most resulting thromboembolisms are cerebral or in the arteries of the lower limbs, and renal artery embolisms are rare. There are reports of a few previous cases of renal infarction with diagnoses of NVM on echocardiography, but a thrombus from the left ventricle has never been identified as the cause of a renal artery embolism. This paper reports a 53-year-old male who was admitted to our hospital for LVNC and renal infarction. He had a history of atrial fibrillation
3 years previously. We diagnosed LVNC with a thrombus in the left ventricle using echocardiography. The patient was discharged after renal replacement therapy and treatment with an anticoagulant. During the 2 years of follow-up, his condition remained stable.
