Figure 71.2 M-mode recording of the mitral valve illustrating the high-frequency fluttering (arrows) of the anterior leaflet characteristic of aortic regurgitation due to aortic valvular flail. BP, blood pressure.

Figure 71.3 Suprasternal notch long-axis view illustrates the reversal flow in the aortic arch (a); pulse Doppler recording shows the forward and reversal flow in the abdominal aorta, which indicates severe aortic regurgitation due to aortic valvular flail (b). AAO, ascending aorta; ABDA, abdomen aorta; DAO, descending aorta.

Figure 71.4 M-mode recording of parasternal long-axis view with color Doppler demonstrates the wide opening of aortic closing line and aortic regurgitant flow persistent in the entire diastolic period, which indicates severe aortic regurgitation.
