Valvular Heart Disease: Difference between revisions

The therapeutic approach for tricuspid regurgitation is dictated by the aetiology of the regurgitation and overall condition of the patient.  In a limited number of patients percutaneous balloon tricuspid dilatation has been performed. This is a treatment option in cases of isolated and pure tricuspid stenosis, but it frequently induces regurgitation.<cite>Vahanian1</cite> Tricuspid balloon valvotomy, combining commissurotomy leaflet augmentation and annuloplasty, can be used to treat tricuspid stenosis; however, with this treatment the potential for inducing severe tricuspid regurgitation still exists. A biological prosthesis is preferred in case of tricuspid valve replacement,since it heas satisfactory long-term durability and mechanical prosthesis caries a higher risk of thrombosis.

Functional tricuspid regurgitation results from distortion of the architecture and coordinated actions of the tricuspid leaflets, annulus, chords, papillary muscles, and right ventricular (RV) wall. This distortion is most commonly caused by right ventricular dilation and dysfunction from left sided heart disease with pressure/volume overload conditions.
