Acute Severe Aortic Regurgitation

Abstract
Acute severe aortic regurgitation in humans is a relatively unfamiliar, though life-threatening, disease. Its diverse causes, anatomic faults and hemodynamic sequelae were reviewed. The clinical manifestations were discussed in light of their physiologic mechanisms. Clinical information includes the natural history, physical signs (physical appearance, systemic arterial pulse, jugular venous pulse, precordial palpation, auscultation), ECG, and chest roentgenogram. Echocardiographic features are especially emphasized, and the need for prompt diagnosis and surgical intervention underscored, even in the setting of active infective endocarditis.
