Pathophysiology of the Rivero-Carvallo Sign in Tricuspid Stenosis

Rivero-Carvallo Sign in Bioprosthetic Tricuspid Valve Stenosis

“… 1 Simultaneous echo Doppler and phonocardiogram revealed that the peak TVG increased during inspiration resulting in louder diastolic rumble ( Figure 1 ). 2 , 3 Because of the significant bioprosthetic tricuspid stenosis, inspiratory fall of the pressure is less prominent in the right atrium than right ventricle. 2 , 3 Therefore, TVG increases during inspiration leading to the louder diastolic rumble.…”

“… 2 , 3 Because of the significant bioprosthetic tricuspid stenosis, inspiratory fall of the pressure is less prominent in the right atrium than right ventricle. 2 , 3 Therefore, TVG increases during inspiration leading to the louder diastolic rumble. This is a modern expression of the classic auscultatory findings of Rivero-Carvallo sign.…”
