ACOUSTIC CHANGES IN NORMALLY FUNCTIONING MITRAL VALVE PROSTHESES: ECHO-PHONOCARDIOGRAPHIC OBSERVATIONS

AUTOR(ES)

Busch, Ulrich

RESUMO

This study confirms previous findings of variability in the intensity of the closing click (CC) as a consequence of premature valve closure. Such alterations have been described as a normal phenomenon in several prosthetic valve models. Combined echo-phonocardiography is of particular value in evaluating prosthetic valve function in patients with unusual and confusing auscultatory changes.
