Tricuspid regurgitation (TR), also called tricuspid insufficiency, is a type of valvular heart disease in which the tricuspid valve of the heart, located between the right atrium and right ventricle, does not close completely when the right ventricle contracts .
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
Tricuspid regurgitation: the backflow of blood from the right ventricle into the right atrium, owing to imperfect functioning (insufficiency) of the tricuspid valve. Regurgitation in or near the heart is often caused by valvular insufficiency (insufficient function, with incomplete closure, of the heart valves); for example, aortic valve ...
Patients with tricuspid regurgitation may experience symptoms of right-sided heart failure, such as ascites, hepatomegaly, edema and jugular venous distension. [ 16 ] Signs of tricuspid regurgitation include pulsatile liver , prominent V waves and rapid y descents in jugular venous pressure . [ 16 ]
Severe tricuspid regurgitation with symptoms; Transient ischemic attack or stroke; The CCS further recommends patients who require operation for Ebstein's anomaly should be operated on by congenital heart surgeons who have substantial specific experience and success with this operation. Every effort should be made to preserve the native ...
The severity of flail leaflet varies, ranging from tip eversion to chordal rupture. Dissociation of leaflet and chordae tendineae provides for unrestricted motion of the leaflet (hence "flail leaflet"). Thus patients with flail leaflets have a higher prevalence of mitral regurgitation than those with the non-flail subtype. [29]
The chordae tendineae connect the atrioventricular valves (tricuspid and mitral), to the papillary muscles within the ventricles. [2] Multiple chordae tendineae attach to each leaflet or cusp of the valves. [3] Chordae tendineae contain elastin in a delicate structure notably at their periphery. [4]
Tricuspid regurgitation is typically treated conservatively by aiming to treat the underlying cause and following up the patient regularly. [12] Surgery is considered in more serious situations where the patient is severely symptomatic. Surgical options include either: replacement of the valve or repair of the valve (termed annuloplasty). [3]
