Tricuspid regurgitation occurs when the tricuspid valve allows retrograde flow of blood from the right ventricle into the right atrium during systole.
A small, clinically insignificant amount of tricuspid regurgitation is present in about 70% of adults and can be considered a variant of normal anatomy.
Most clinically significant tricuspid regurgitation is functional; elevation of right ventricular end-systolic pressure (RVESP) cau
