Surgical correction of a previously unreported association of cor triatriatum and lipomatous hypertrophy of the interatrial septum in a 75-year-old woman resulted in an uncomplicated postoperative course and discharge within one week.
Case Report (n=1)
This case report describes a rare and previously unreported association of cor triatriatum and lipomatous hypertrophy of the interatrial septum in an elderly patient, successfully treated with surgery.

Surgical correction was uncomplicated in this elderly patient; extends reported atrial anomalies but leaves open prevalence and management questions.
Cor triatriatum is a rare congenital heart defect characterized by the presence of a fibromuscular membrane dividing the left atrium into two distinct chambers. Lipomatous hypertrophy of the atrial septum is an infrequently observed benign abnormality caused by large fatty tissue deposits in the interatrial septum. An increased incidence of atrial arrhythmias is described in both pathologies, while a significant obstruction of blood flow mimicking mitral stenosis is typically manifested in cor triatriatum. We report the case of a 75-year-old woman with a previously undescribed association of the above stated abnormalities detected by both transthoracic and transeosophageal echocardiography. Diagnosis was confirmed by means of computed tomography. The singular physiologic and anatomic factors underlying survival until such a late age are described. The diagnostic, therapeutic and surgical management is discussed and a short review of the literature performed.

Bassareo et al. (2010) conducted a case report in Cor triatriatum and lipomatous hypertrophy of the interatrial septum (n=1). Surgical excision of intra-atrial membrane and partial removal of fatty tissue mass with CABG was evaluated on Postoperative recovery. Surgical correction of a previously unreported association of cor triatriatum and lipomatous hypertrophy of the interatrial septum in a 75-year-old woman resulted in an uncomplicated postoperative course and discharge within one week.
