Tricuspid Regurgitation

Pathology:                    Incompetent Tricuspid valveallowing backflow of blood into right atrium


Aetiology:                     Right ventriculardilatation, right ventricular infarction, rheumatic fever,

pulmonary hypertension, infectiveendocarditis, chronic heart disease, carcinoid, Ebstein malformation due tolithium maternal therapy causing apical displacement of the tricuspid valveleaflets leading to atrialization of the right ventricle


Symptoms:                  Rightheart failure, anorexia, nausea, abdominal pain


Signs:                              RaisedJVP, giant ‘v’ waves, right ventricular parasternal heave, AF, pansystolicmurmur at the left lower sternal edge loudest on inspiration. 3rdheart sound, ascites, peripheral oedema, pulsatile and tender hepatomegaly


Investigations:          ECG: Right axis deviation andconduction delay

                            Chest X-Ray: cardiomegaly

Echo: Assesses for leaflet abnormalities andestimates pulmonary pressures


Treatment:                  Medical: Salt restriction

Diuretics for peripheral oedema

Complications:          Arrhythmias


Prognosis:                  Related to underlying cause
