Hemodynamically compromising left atrial (LA) compression by an aortic aneurysm is a rare entity. An 83-year-old woman with a previous diagnosis of congestive heart failure was admitted with worsening shortness of breath (NYHA grade III) and palpitations. The electrocardiogram showed atrial fibrillation. The chest X-ray revealed widening of the mediastinum and congested lung fields. Transthoracic echocardiography demonstrated LA compression by a large descending thoracic aortic aneurysm. Left and right ventricle systolic functions were preserved. Thoracic three-dimensional magnetic resonance imaging showed LA compression by a descending aortic aneurysm and an intramural hematoma. No intimal flap was seen in any part of the thoracic aorta. Emergency surgery was planned, but the patient did not accept surgery and suddenly died after four days of admission. Focal descending aortic aneurysm with an intramural hematoma in the aortic wall causing nearly complete obliteration of the LA cavity has not been reported before.
