Abstract

Recurrent tricuspid regurgitation (TR) can occur after tricuspid annuloplasty if severe leaflet tethering persists. To reduce the tethering, we applied right ventricular papillary muscle approximation in 7 patients with severe functional TR associated with significant leaflet tethering. Postoperative echocardiogram revealed mild or less TR and a significant reduction in the tethering effect. In conclusion, this adjunctive technique can improve functional TR associated with leaflet tethering.

摘要

如果严重的瓣叶牵拉持续存在，三尖瓣环成形术后可能会出现复发性三尖瓣反流（TR）。为了减轻牵拉，我们对7例伴有明显瓣叶牵拉的严重功能性TR患者应用了右心室乳头肌靠拢术。术后超声心动图显示TR为轻度或更低程度，且牵拉效应显著降低。总之，这种辅助技术可以改善与瓣叶牵拉相关的功能性TR。
