  • Radiofrequency Catheter Ablation for Atrial Tachycardia in Patients after Radiofrequency Ablation of Atrial Fibrillation during Mitral Valve Replacement

    ObjectiveTo investigate heart rhythm outcomes of radiofrequency ablation (RFA)of atrial fibrillation (AF)during mitral valve replacement (MVR)for patients with rheumatic heart disease (RHD), and explore clinical results of radiofrequency catheter ablation (RFCA)for postoperative atrial tachycardia (AT). MethodsEleven RHD patients who developed AT after RFA of AF during MVR were enrolled in this study. There were 4 males and 7 females with their age of 49±8 years. Electroanatomic mapping of the left or right atrium was conducted with three-dimensional electroana-tomic mapping system during continuous AT. RFCA was performed at the key areas of AT. ResultsFor MVR, operation time was 149±18 minutes, postoperative hospital stay was 9.5±2.9 days, and length of ICU stay was 1.8±0.4 days. During electroanatomic mapping, 17 ATs were recorded in 11 patients. Six ATs (35%)of 5 patients originated from the right atrium and 11 ATs (65%)of 6 patients originated from the left atrium (LA). Among them, AT of 2 patients was related to the mitral valve ring. Immediate success of RFCA was obtained in 91% (10/11). After a mean follow-up of 17±4 months, 2 patients whose AT originated from LA had AT recurrence. ConclusionsMajority of postoperative ATs originate from LA, and majority of ATs are not mitral-dependent. RFCA is an effective and safe procedure for AT in patients after RFA of AF during MVR.

  • Clinical Characteristics and Prognosis of Pateints with Coronary Artery Anomalies

    目的:了解有症状冠状动脉异常患者的临床特点和预后。方法:搜集1999年11月~2005年10月期间,因胸痛在心导管室行冠状动脉造影的病例,分析冠状动脉异常患者所占构成比,对该类患者进行随访,分析其临床特点及临床终点事件(死亡、心脏猝死、心肌梗死以及血运重建等)的发生情况。结果:在研究期间,共2003例胸痛患者进行了冠状动脉造影,74例患者有冠状动脉异常(构成比3.7%),包括心肌桥54例、冠状动脉瘘16例、冠状动脉异常起源3例、单支冠状动脉1例。其中23名冠状动脉异常患者伴发有严重的冠状动脉粥样硬化病变或主动脉瓣病变。对无上述伴发疾病的冠状动脉异常患者进行随访,在随访期内(平均随访40月),与冠状动脉正常患者相比,该类患者临床终点事件发生率无差异。结论:在有胸痛症状行冠状动脉造影的患者中,冠状动脉异常的构成比较低。该类患者的临床预后近似于冠状动脉正常患者。
