Tricuspid Valve Repair With Neopapillary Muscle From Right Ventricular Trabecula
2010
Congenital abnormalities of the tricuspid valve without downward displacement of the septal and posterior tricuspid leaflets are uncommon causes of tricuspid regurgitation. Progressive tricuspid regurgitation can lead to right heart dilatation, arrhythmia, and irreversible deterioration of right ventricular function. Tricuspid valve repair is an important method to stabilize symptomatic children because tricuspid valve replacement has a poor prognosis. We report the successful use of right ventricular trabecula as a "neopapillary muscle" for treating severe low-pressure tricuspid regurgitation in children.
