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.
三尖瓣无隔瓣和后瓣下移的先天性畸形是三尖瓣反流不常见的原因。进行性三尖瓣反流可导致右心扩张、心律失常和右心室功能不可逆恶化。三尖瓣修复是稳定有症状儿童的重要方法，因为三尖瓣置换的预后较差。我们报告了成功使用右心室小梁作为“新乳头肌”治疗儿童严重低压三尖瓣反流。
