ABSTRACT
Left atrial aneurysm (LAA) is extremely rare. We report a surgical case of LAA complicated with mitral regurgitation (MR) and severe heart failure. A 71-year-old man presented dyspnea and leg edema, followed by congestive heart failure. Transthoracic echocardiogram (TTE) showed moderate MR, deteriorated left ventricular function, and echo free space connecting to the posterior wall of the left atrium. Three-dimensional reconstruction of computed tomography (3D-CT) clearly showed the whole shape of the LAA and its location relating to surrounding structures. LAA was 5×6 cm, expanding to apex side, and originated from the posterior wall of left atrium between circumflex branch of the left coronary artery and coronary sinus. LAA wall extended to the mitral posterior annulus, causing annular deformity and MR. Mitral valve plasty and aneurysmorrhaphy were performed. Biventricular pacing leads were implanted for cardiac resynchronization therapy, because of severe heart failure. Postoperative 3D-CT showed reduction of the LAA with no deformity of coronary vessels. No MR was detected by postoperative TTE. The patient has recovered without any complication after our treatments.
