摘要 目的探讨经胸心外膜左心室起搏电极植入在慢性充血性心力衰竭心脏再同步化治疗(cardiac resynchronization therapy,CRT)中的应用及疗效。方法对4例不适合植入心内膜电极的慢性充血性心力衰竭的患者,采用小切口经左胸第四或五肋间放置心外膜电极,分析心外膜电极的外科手术植入技术及近期疗效。结果 4例患者心外膜电极安装均顺利完成,术后血流动力学、心功能及症状明显改善,分别于术后8、11、4和7 d顺利出院,随访12个月。4例患者均无电极断裂及手术伤口感染发生,起搏阈值、电极阻抗正常。其中1例由于放置位置偏低,出现膈神经刺激征,当向内向上微调电极位置后膈神经刺激征不明显,未出现其他并发症;1例患者术后1年出现囊袋感染,起搏器异位,再次行更换起搏器手术。结论在CRT治疗中,左侧小切口开胸心外膜左心室电极植入是安全、可行、有效的,介入手术与心脏外科开胸合作的杂交手术可以使CRT疗效最大化,是可选择的方法。
