No immediate change to auscultation practice; leaves open generalization beyond normal valves in prospective studies.
Observational (n=16)
Echographic coaptation of the aortic valve leaflets coincides with the trough of the aortic pressure incisura and the onset of A2, suggesting that the A2 sound is a result of valve closure.
Hirschfeld et al. (1977) reported an observational. Simultaneous echographic, pressure, and sound recordings was evaluated on Temporal relationship of the echographic, pressure, and sound parameters of aortic valve closure. Simultaneous recordings demonstrated that echographic coaptation of the aortic valve leaflets coincides with the trough of the aortic pressure incisura and the onset of A2.
