Abstract

|
|
|
A 78-year-old woman presented to our hospital with progressive dyspnea (NYHA class I-II) and epigastric discomfort that had developed after a traffic accident. She had a history of hypertension and cerebral infarction, but no history of cardiovascular disease. Her blood pressure was 130/70 mmHg and her heart rate was 66 beats/min and regular. The electrocardiogram showed normal sinus rhythm. The chest X-ray revealed bilateral pleural effusions. Transthoracic echocardiography (TTE) demonstrated an aneurysm of the descending thoracic aorta compressing the left atrium (LA). Left and right ventricular systolic function was preserved. Whole-body computed tomography (CT) angiography revealed that a focal 40-mm-diameter saccular aneurysm in the descending aorta at the level of T7-8, with an intramural hematoma, was compressing the LA and left pulmonary vein. After surgical management, follow-up TTE and CT showed decompression of the LA and left pulmonary vein.
