4.12 Tricuspid Stenosis, Tricuspid Regurgitation, Carcinoid Disease

In this episode, we review tricuspid stenosis (TS) and tricuspid regurgitation (TR). What are the echocardiographic criteria for diagnosing severe TS, and how does it differ from that of severe mitral stenosis? Which etiology of TR would have diffuse leaflet thickening with restriction of opening due to commisural fusion, chordal shortening, and calcification with characteristic diastolic doming? Which etiology of TR would have short, thick leaflets with systolic and diastolic restriction? Which etiology of TR would have apical displacement of the tricuspid valve septal and posterior leaflets from the atrioventricular ring? What would the jugular venous pressure and central venous pressure waveform of TR show? What are the qualitative, semiquantitative, and quantitative features on echo for quantifying TR severity? Are there any indications for moderate TR to undergo tricuspid valve surgery? Are there any indications for asymptomatic severe TR to undergo tricuspid valve surgery? Tune in for answers to these questions.
