Abstract:
Objective: To investigate the safety and effectiveness of three-dimensional (3-D) rotational angiography reconstruction of left atrial and pulmonary vein stereo image embedded with real-time X-ray fluoroscopy system for guiding radiofrequency catheter ablation (RFCA) in treating the patients with atrial ifbrillation (AF).
Methods: A total of 60 consecutive AF patients who received RFCA in our hospital from 2011-04 to 2013-04 were studied. The patients were randomly divided into 2 groups and 3-D Carto3 mapping system was applied for guiding RFCA in both groups. n=30 in each group. Treatment group, the patients received Siemens ARTIS Zeego digital subtraction system for left atrial and pulmonary vein rotational angiography, then, stereo images were reconstructed and embedded with real-time X-ray lfuoroscopy for RFCA guidance. Control group, conventional left and right pulmonary venography was conducted for RFCA guidance. The procedural and X-ray exposure times, rates of success and complications were recorded and compared between 2 groups.
Results: All 60 patients had successful RFCA, compared with Control group, the patients in Treatment group had obviously less procedural time and X-ray exposure time, while the success rate and complications were similar between 2 groups.
Conclusion: 3-D rotational angiography reconstruction of left atrial and pulmonary vein stereo image embedded with real-time X-ray lfuoroscopy system is safe and effective for guiding RFCA in treating the AF patients, which may reduce the procedural and X-ray exposure times.
