心脏瓣膜手术同期冷冻消融治疗心房颤动的临床研究

Cryomaze ablation procedure for atrial fibrillation concomitant with valve surgery

目的评价瓣膜手术同期冷冻消融术的安全性和疗效。方法回顾性分析我院2013年8月至2015年7月62例风湿性心脏瓣膜手术同期行心房颤动(房颤)冷冻消融患者的临床资料。其中男24例、女38例,年龄(49.4±14.2)岁。术后追踪复查12导联心电图观察心律情况。结果术后即刻窦性心律转复率为98.4%,出院时为93.4%。术后第3、6、12、18个月的窦性心律分别为90.2%、87.3%、85.0%和83.3%。35例微创二尖瓣手术组术后1年窦性心律维持率为90.5%,术前房颤持续时间长于7年的患者术后1年房颤复发率增高(P<0.05)。结论心脏瓣膜手术同期行房颤的冷冻消融治疗效果安全有效,短期随访房颤复发率低。

Objective To summarize safety and effectiveness of cryomaze ablation procedure concomitant with valve surgery. Methods We retrospectively investigated the clinical data of 62 patients （24 males and 38 females） with mean age of 49.4±14.2 years who underwent cryomaze ablation procedure concomitant with valve surgery in our hospital from August 2013 through July 2015. The heart rhythm of the patients after surgery was supervised by 12-leads electrical cardiogram respectively. Results The rate of sinus rhythm restored right after surgery was 98.4%. The rate of sinus rhythm restored at the time of discharge was 93.4%. The rate of sinus rhythm restored 3 months, 6 months, 12 months, 18 months after surgery was 90.2%, 87.3%, 85.0%, 83.3% respectively. The one-year post-operation rate of sinus rhythm restored for the group of right minimal invasive thoracoscopic assisted mitral valve surgery was 90.5%. Longer duration for atrial fibrillation （〉7 years） was a risk factor for the reoccurrence of atrial fibrillation 1 year after surgery （P〈0.05）. Conclusion Cryomaze ablation procedure concomitant with valve surgery is quite effective in treatment of rheumatic valve disease and atrial fibrillation. This approach is associated with fewer complications, comparable atrial fibrillation reoccurrence for short-term follow-up.
