3.2 | Acute results
The acute procedure outcomes are summarized in Table 2. The mean number of right pulmonary vein (RPV) applications was 29.4±11.7, 29.9±12.7 applications for left pulmonary vein (LPV), 8.5±4.2 applications for LAPW ablation, 22.5±9.0 applications for CTI ablation, and 61.0±27.6 applications for MI ablation. The mean ablation times of RPV, LPV, LAPW, MI, and CTI were 9.3±5.4, 12.0±6.7, 1.7±1.4, 17.6±11.0, and 6.4±5.7 mins, respectively. PV and LAPW were both successfully isolated in all 32 patients (100%). Complete bidirectional CTI block and MI block were achieved in 31 (96.9%) and 26 patients (81.3%), respectively. The mean fluoroscopy time was 4.4±1.4 mins, and the total procedure time was 78.6±31.3 mins.
Direct conversion of AF to sinus rhythm (SR) occurred in 7 (21.9%) patients, while in 5 (15.6%) patients, AF was first converted into atrial flutter ( 3 [9.4%] atypical flutter and 2 [6.2%] typical atrial flutter) and then into SR. Electrical cardioversion was performed in the remaining cases (20 [62.5%]) where ablation did not restore SR. (Figure 1 )
