The team used a control system to pressurize the actuators with a sequential delay of 20 to 50 m/s to replicate peristaltic-like RV ejection. Trabeculae, valves, papillary musculature, and ...

A new study finds that the anatomy of the heart's tricuspid valve can be used to predict the severity of leakage in the valve -- a condition called tricuspid regurgitation. An estimated 1.6 ...

Patients with ventricular secondary tricuspid regurgitation have dilatation of the right ventricle (mainly the midventricular free wall), leading to apical displacement of the papillary muscles ...

Contraction of the papillary muscles opens the valve and relaxation of the muscles closes the valve. The study showed that papillary displacement alone resulted in significant tricuspid leakage.
