Reversible left ventricular function after tricuspid valve replacement for a patient with congenital isolated severe tricuspid regurgitation.

摘要

We describe the case of a 30-year-old man presenting with congenital, isolated severe tricuspid regurgitation due to posterior leaflet dysfunction. An impaired left ventricular ejection fraction and restrictive filling pattern were noted, recovering after tricuspid valve replacement. The left ventricular dysfunction, reversible in this case, may have been the result of right ventricular volume overload, resulting in ventricular septal paradox.
