本研究旨在探讨术中心房激动标测是否有助于二尖瓣病变合并慢性房颤的手术治疗。方法对12例二尖瓣病变合并慢性房颤患者行术中电生理标测指导手术治疗。在12例患者中，有10例在左心耳和/或左肺静脉口有规律的、重复的激动(周期118~210毫秒)。在其余2例患者中，左心房交替出现显性重复激动和散发性复合激动。结果在术中标测的基础上，在重复激动的突破点进行了左心耳切除和/或左肺静脉口冷冻消融等手术。11例患者均未行右心房手术。术后10例(83%)维持窦性心律6~40个月，平均24.8个月。结论多数二尖瓣病变患者的左房为慢性房颤的电驱动腔。计算机化的术中标测应指导外科医生确定治疗慢性房颤的适当手术方式。
BackgroundThis study was designed to determine if intraoperative atrial activation mapping facilitates operations for chronic atrial fibrillation associated with mitral valve disease.MethodsSurgical treatment guided by intraoperative electrophysiologic mapping was performed in 12 patients with chronic atrial fibrillation associated with isolated mitral valve disease. In 10 of 12 patients, regular and repetitive activation (cycle length ranged from 118 to 210 msec) originated in the left atrial appendage and/or orifice of the left pulmonary vein. In the remaining 2 patients, dominant repetitive activation and sporadic complex activation were alternately observed in the left atrium. However, the activation sequence of the right atrium was extremely complex and chaotic.ResultsOn the basis of intraoperative mapping, surgical procedures, including resection of the left atrial appendage and/or cryoablation of the orifice of the left pulmonary vein, were applied on the breakthrough site of the repetitive activation. No surgical procedure was performed on the right atrium in 11 patients. Ten of 12 patients (83%) have maintained sinus rhythm for 6 to 40 months (average 24.8 months) after operation.ConclusionsIn the majority of the patients with isolated mitral valve disease, the left atrium acts as an electrical driving chamber for chronic atrial fibrillation. Computerized intraoperative mapping should guide surgeons in determining the appropriate surgical procedure for chronic atrial fibrillation.
