title: The Echocardiographic "Spike and Dome"--Obstruction It Is But Where?
abstract: Spectral Doppler interrogation of the descending thoracic and abdominal aorta provides valuable information regarding cardiac and vascular hemodynamics. An abnormal aortic Doppler profile is encountered in pathological conditions that affect the aorta and its branches, the aortic valve, the left ventricle, and the pericardium. Characteristic findings on Doppler interrogation of the aorta are often noted in individuals with obstructive atherosclerotic disease of the aorto-iliac system including severe stenosis or occlusion of the distal aorta and/or iliac arteries. In this manuscript, we highlight the findings on spectral Doppler that led to the identification of occlusive disease in the distal aorta.
