A Cases of Tuberculous Pericarditis Associated with Pseudoaneurysm of the Left Ventricle

The incidence of left ventricular pseudoaneurysm is not known, but it appears to be quite rare. We experienced a case of apical pseudoaneurysm of left ventricle in a 73-year-old female who presented with progressive orthopnea. On the 2nd hospital day, cardiac tamponade developed. A small pseudoaneurysm of left ventricle with narrow neck associated with massive pericardial effusion was demonstrated by transthoracic echocardiography. Emergency coronary angiogram showed normal. Emergency operation was performed on the suspicion of rupture of the pseudoaneurysm. Microscopic examination of the wall of the aneurysm revealed fibrous tissue adhered to the granulomatous inflammatory pericardium.
