Abstract:
To explore the safety and efficacy of left atrial appendage (LAA) occlusion under the guidance of local anesthesia and modified transseptal puncture technology by coronary sinus assisted positioning in patients with nonvavular atrial fibrillation (NVAF). Methods: A total of 16 NVAF patients received local anesthesia and percutaneous LAmbre or Amplatzer cardiac plug occluder implantation. There were 12 males and the patients mean age was at (71.0±6.0) years with CHA2DS2-VASc score at (4.1±1.5); all patients had walfarin contradiction or with walfarin related side effect. Transseptal puncture was conducted by coronary sinus catheter as the anatomic location marker. Results: All 16 patients finished transseptal puncture and no relevant complication occurred. 15/16 (93.8%) patients had successful LAA occlusion, 1 patient was abandoned because of LAA anatomic structure variation. The mean operative time was (65.0±23.0) min and the mean X-ray exposure time was (12.0±3.0) min. The mean diameter of occluder was (32.5±6.0)mm. Conclusion: LAA occlusion was safe and effective with local anesthesia and modified transseptal puncture technology by coronary sinus assisted positioning in relevant patients.
