title: [Transcatheter closure of atrial septal defects in a patient with lipomatous hypertrophy of the interatrial septum].
abstract: Lipomatous hypertrophy of the interatrial septum is a rare benign pathology characterized by fatty deposits in the septum and is mostly diagnosed incidentally. This accumulation mostly causes a globular thickening of the interatrial septum, commonly sparing the fossa ovalis. We report on a 65-year-old female patient who underwent successful transcatheter closure of atrial septal defects (ASD) accompanied by lipomatous hypertrophy of the septum. Both transthoracic and transesophageal echocardiography showed enlargement of the right heart cavities, thickening of the interatrial septum (16 mm) with bright echogenicity, and two separate secundum ASDs measuring 17 mm and 4 mm, respectively. Transcatheter closure of the defects was performed using a 24-mm Amplatzer septal occluder. There was no residual shunt and Holter monitoring was normal after the procedure. During a three-year follow-up, no complications were observed pertaining to the procedure or lipomatous tissue.
