This occurs due to any cause of pulmonary hypertension which in turn results in increased right ventricular pressure dilating the tricuspid valve annulus. Rare causes include pacemaker lead ...

It goes into the right atrium, through the tricuspid valve and into the right ventricle. The ventricle pumps the blood through the semilunar valve, into the pulmonary artery and to the lungs.

In healthy individuals, blood flows into the heart's right atrium through the tricuspid valve, into the right ... via a ductus arteriosus connecting the pulmonary artery to the aorta.
