Echocardiography may expedite diagnosis of acute AR in bicuspid-valve endocarditis; leaves open prospective validation before broader adoption.
A 23-year-old Japanese male with no evidence of previous heart disease was presented with bicuspid aortic valve and a life threatening acute aortic regurgitation due to subacute bacterial endocarditis. By echocardiographic techniques, a precise diagnosis was made based on the following findings: 1) premature mitral valve closure, 2) snowfall-like echoes between the systolic aortic cusps, 3) eccentricity of a diastolic aortic valvular echo. The echocardiographic diagnosis was confirmed on surgery, in which aortic valve replacement was performed with satisfactory postoperative results.
