Foregut Cyst in Heart: Case Report

AbstractA 70-year-old female presented with gradual onset of dyspnea with moderate exertion for 6 months. She had a history of stroke 1 month back which was resolved. On two-dimensional echo, she had a mass in left atrium (1.6 × 1.6 cm) with base attached to interatrial septum adjacent to anterior mitral leaflet. On coronary angiography, she had lesion in left anterior descending coronary artery (LAD) with 60 to 70% stenosis. But intraoperative transesophageal echocardiography revealed mass in left ventricle attached to posterior mitral leaflet undersurface. The operation was performed; coronary artery bypass graft surgery with left internal mammary artery to LAD grafting and transannular decompression of the left ventricular mass was performed. Surgery was done uneventfully. The cyst content consisted of necrotic sebaceous-type material with calcification. Histopathology of excised material revealed it to be a foregut cyst of myocardium. The patient had an uneventful postoperative course and was discharged in good clinical condition.
