Momentary and wide aortic regurgitation as an indicator of aortic dissection
- 263 Downloads
A 55-year-old female with a history of hypertension was admitted for dyspnea, epigastralgia and nausea. A chest X-ray showed pulmonary congestion. Transthoracic echocardiography (TTE) revealed severe left ventricular dysfunction with akinesis of the infero-posterior wall and Doppler color-flow mode showed mild aortic regurgitation (AR). Noninvasive positive pressure ventilation, intravenous heparin and diuretics were administered. Follow-up TTE revealed a dissection flap as well as momentary and wide AR only during isovolumetric relaxation. Contrast-enhanced computed tomography of the chest revealed Stanford type A aortic dissection. A momentary and wide AR in echocardiograms might serve as an important and useful indicator of aortic dissection in patients with acute myocardial infarction and congestive heart failure.
