摘要 【目的】探讨环肺静脉隔离联合左心房顶部线性消融术治疗阵发性房颤的临床疗效。【方法】选择本院收治的80例阵发性房颤患者,按照治疗方案的不同将其分成对照组(环肺静脉隔离术治疗)和观察组(环肺静脉隔离术+左心房顶部线性消融术),每组各40例。比较两组手术相关指标、手术前后左心房结构和功能相关指标,并统计两组消融成功率。【结果】观察组的消融和手术时间均明显长于对照组(P<0.05),但两组X线曝光时间和围术期并发症发生率比较,差异均无统计学意义(P>0.05)。两组术后的LAD、LAVmin和LAVmax数值均较术前明显降低(P<0.05),LVEF、LAAEF均较术前明显升高(P<0.05),且观察组术后的各项左心房结构和指标功能均明显优于对照组(P<0.05)。两组的消融成功率比较,差异无统计学意义(P>0.05)。【结论】环肺静脉隔离联合左心房顶部线性消融术治疗阵发性房颤可在一定程度逆转左心房结构重构,有效改善患者心功能,且不增加术中X线曝光时间和术后并发症,临床治疗安全、可行。
