Different types of tricuspid flail: Case reports and review of the literature.

AbstractTricuspid regurgitation (TR) is a common Doppler echocardiographic finding resulting from either intrinsic valve abnormalities or functional malcoaptation of structurally normal valves. TR caused by flail leaflets is most often post-traumatic, is caused by endocarditis or is a consequence of a myxomatously degenerated valve. The clinical presentation is severe and is characterized by excess mortality and high morbidity. Flail leaflets are reliably diagnosed using 2-dimensional and 3-dimensional echocardiography
