Echocardiography can identify specific signs such as mid-diastolic aortic valve opening and premature mitral valve closure in severe acute aortic regurgitation.
Echocardiographic signs may aid acute severe AR recognition in select cases; leaves open prospective validation before broader adoption.
A case of severe acute aortic regurgitation is reported. Echocardiographic findings included mid-diastolic opening of the aortic valve, premature closure of the mitral valve, diastolic shuddering of the anterior mitral leaflet, probable demonstration of the flail aortic cusp in the left ventricular outflow tract, and increased left atrial and left ventricular dimensions. Correlation with hemodynamic, angiographic and surgical evidence is made.
