The fifth cardiac chamber: Case of a huge left atrial appendage aneurysm

A 35 year old female was referred to the Cardiology department of Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, India in May 2014 for evaluation of shortness of breath which she had for the last two years. The patient was in sinus rhythm and cardiovascular examination was normal. Chest X-ray revealed a normal sized heart with a prominent bulge in the mid left cardiac border [Figure 1], Panel A).

Trans-thoracic echocardiography with 3-D reconstruction revealed a large, elliptical left atrial appendage (LAA) aneurysm compressing the left ventricle (LV); the appearance of the large aneurysm extending along the LV lateral wall simulating a five-chambered heart on the modified apical and para-sternal short-axis views [Figure 1], Panels B-D, Videos 1 & 2). The aneurysm was devoid of any thrombus, mitral and tricuspid valves were normal without any rheumatic involvement and bi-ventricular function was normal. A large, isolated LAA aneurysm arising from the left atrium was confirmed on trans-oesophageal echocardiography; pulse Doppler interrogation revealed preserved appendage filling and emptying pattern (Video 3). A 64-slice multidetector cardiac CT imaging with volume reconstruction was performed which clearly delineated a 51 x 66 mm LAA aneurysm extending antero-superiorly and to the left of the LV cavity [Figure 2], Panels A-D). The patient was diagnosed to have an LAA aneurysm. She declined any surgical intervention; despite appendage flow being preserved, oral anticoagulation (OAC) was started to prevent any future thrombo-embolic events. The patient remained asymptomatic at the last six month follow up.
