Direct examination of the aortic orifice at the level of the aortic valves (aortic valvular orifice area, AVOA) in the short-axis plane was performed with a 3 MHz two-dimensional pulsed Doppler echocardiographic apparatus. The AVOA was mapped with the Doppler gate to detect or rule out the presence of a regurgitant aortic valvular area (RAVA) established by recording of abnormal diastolic Doppler signals on a "yes or no" basis. A group of 12 normal subjects and 83 patients, including 40… CONTINUE READING
