Dissecting aneurysm of the thoracic aorta presenting as right atrial obstruction.
Abstract
A patient with a dissecting thoracic aortic aneurysm presented with acute low output cardiac failure due to right atrial obstruction. Five years earlier she had had her aortic valve replaced because of aortic regurgitation. Obstruction of the superior vena cava and pulmonary artery has been reported elsewhere as a complication of compression by thoracic aortic dissecting aneurysm. This case was unusual in presenting as right atrial obstruction.
