Transvenous leads are a known source of iatrogenic tricuspid regurgitation. It is commonly held that extraction of chronic pacing and defibrillator leads will not reduce this, due to the inevitable trauma to the valve associated with the procedure. We demonstrate three cases of clinically significant reductions in tricuspid regurgitation after extraction of leads that were looped across the tricuspid valve.
经静脉导线是医源性三尖瓣反流的一个已知来源。人们普遍认为,由于与该操作相关的不可避免的瓣膜创伤,慢性起搏和除颤导线的拔除不会减少这种情况。我们展示了三例在拔除横跨三尖瓣的导线后三尖瓣反流出现临床显著减轻的病例。
