Heart:Fontan术后心律失常发生率很高

Fontan手术适应于无法根治的复杂性先天性心脏畸形。改良后的Fontan手术可以减少术后心律失常的发生率。研究者进行了一项回顾性分析,通过对Fontan术后患者的长期随访,评估 心律失常的发生率和结局。该研究纳入了2001-2013年间的166名行了Fontan手术的患者(AP Fontan 63%,LT 13%,TCPC 24%),平均年龄29.1岁。Fontan术后平均随访18.6年。42%

Fontan手术适应于无法根治的复杂性先天性心脏畸形。改良后的Fontan手术可以减少术后心律失常的发生率。研究者进行了一项回顾性分析,通过对Fontan术后患者的长期随访,评估心律失常的发生率和结局。

该研究纳入了2001-2013年间的166名行了Fontan手术的患者(AP Fontan 63%,LT 13%,TCPC 24%),平均年龄29.1岁。Fontan术后平均随访18.6年。42%(70)的患者发生了至少一次的快速性心律失常。对AP Fontan患者随访至少26年,发现心律失常为百分之百。最常见的心律失常是心房内折返性心动过速(66%)。LT和TCPC组心律失常发生率23%(平均随访19.6年和13.6年)。44名患者经历了电击复律,30名进行了消融,10名进行了 Fontan转换手术。生存分析显示,不管Fontan手术是哪种方式,只有年龄是术后发生心律失常的预测因子(p<0.001)。

研究结果表明,Fontan循环成年患者心律失常发生率更高,尤其是AP Fontan,心律失常可以视为必然结局。就算手术方法一直在改进,心律失常的发生率仍很高。

Int J Cardiol:Fontan术后房性心律失常引起大块血栓

Fontan手术常用于解剖性或功能性单心室的儿科病人,通过手术让静脉血流绕过单心室直接进入肺动脉。其中最常见的形式是心房肺动脉吻合,即连接右心房和肺动脉,这种情况下,右心房压力会升高,从而引起心房扩张并损伤窦房结或引起窦房结血液供应障碍,最终导致阵发性或持续性心律失常。Fontan手术人群中房性心动过速和心房颤动屡见不鲜,加重右心房中本已流速缓慢的血液湍流,并促进血栓的生成,增加血栓栓塞的风险。
