Location:
Between right atrium and right ventricle.

Function:
Ventricular diastole: valve opens, allows ventricle to fill.
Ventricular systole: valve closes, preventing reflux into atrium.

Importance in cardiovascular diseases:
Functional abnormalities include tricuspid stenosis and tricuspid regurgitation.

Importance in device delivery:
May be affected by lead implants; artificial tricuspid valve is a contraindication for right ventricular endocardial pacing leads.
