Incidental Finding of Lipomatous Hypertrophy of the Right Atrial Free Wall in an Elderly Female With Severe Pulmonary Hypertension: Early Detection by Multimodality Imaging

Lipomatous atrial hypertrophy (LAH) is a benign cardiac lesion characterized by fat accumulation in the interatrial septum that spares the fossa ovalis. It is associated with obesity and is more frequently observed in elderly and female patients. It is most often detected as an incidental finding on transthoracic echocardiography (TTE). The deposition of adipose tissue may rarely involve both the interatrial septum and the right atrial (RA) free wall. Herein, we describe an extremely rare case of LAH limited to a portion of the RA free wall only, mimicking a myxoma or a thrombotic formation. A multi-instrumental evaluation comprehensive of TTE implemented with pulsed-wave tissue Doppler imaging (PW-TDI), transesophageal echocardiography (TEE), and computed tomography (CT) angiography, performed during the patient's stay in the emergency department, allowed to quickly diagnose the benign RA pseudomass.

Annular Indentation of the Ventricles in a Stillborn: A Case Report and Literature Review

BackgroundIdiopathic indentation of the cardiac ventricles in a fetus has not been previously reported. Reported cases of congenital ventricle indentation are either caused by pericardial abnormalities or myocardial defects. Case report: We describe an incidental finding of annular indentation of the lower part of both ventricles in a stillborn male. The fetus was well-developed and the cause of stillborn was pronounced cord entanglement twice around the neck. Conclusion: Circumferential indentation of ventricles is distinguished from constrictive pericarditis and other myocardial defects as histologically the three layers of endocardium, myocardium, and pericardium are intact.
