A 32-year-old man with a dissecting aortic aneurysm, asymmetrical annulo-aortic ectasia and atrial septal defect was examined by 2-D echocardiography before emergency operation of cardiac tamponade. The patient complained of precordial and back pain and shortness of breath during exertion for 2 days before coming to the out-patient clinic at our hospital. The chest roentgenogram did not reveal an ascending aortic aneurysm, but 2-D echocardiography showed a marked dilatation of the ascending aortic aneurysm (atypical annulo-aortic ectasia) and a slight pericardial effusion.
2-D color Doppler flow mapping was helpful in preoperatively diagnosing artial septal defect and moderate aortic regurgitation.
Thus, in a cardiac emergency requiring surgical treatment, 2-D echocardiography proved useful, especially in diagnosing the ascending aortic aneurysm in the case without abnormality of the chest roentgenogram.
