Palpitations as manifestation of lipomatous hyperplasia interatrial septum: case report and review of the literature
Moreno-Pallares, Eiman; Vargas-Vergara, Diana; Bornacelly, Adriana
ABSTRACT
Lipomatous hypertrophy of the interatrial septum is increasingly recognized and should be considered as part of the differential diagnosis of any cardiac tumor. We present the case of a 70-year-old patient who presented to the outpatient service for palpitations. Transthoracic echocardiogram (TTE) detected thickening of the interatrial septum with proximal predominance with respect to the fossa ovalis. The diagnosis was confirmed by cardiac magnetic resonance imaging. In such cases, the opinion of a cardiologist with expertise in cardiac imaging would help to avoid misdiagnosis and unnecessary intervention. This condition is more common than initially thought and remains under-recognized by most physicians.
