RECURRENCE, SENSITIVITY
In this study, 79 PV occlusions in 20 patients with KODEX-EPD were analyzed. All PVs were electrically isolated. Compared to the results of the X-ray evaluation, a total of 78 times (42.8%) were completely occluded, 58 times were small leaks (31.9%), and 46 times were large leaks (25.3%). Overall, when the X-ray results indicate completely occluded, the sensitivity of KODEX-EPD injection tool in predicting the outcome of PV occlusion was 93.6% (95% CI 85–97.6%, P < 0.01), the specificity was 69.6% (95% CI 54–81.8%, P < 0.01), and the positive predictive value was 83.9% (95% CI 74.1–90.6%, P < 0.01). The negative predictive value was 86.5% (95% CI 70.4–90.6%, P < 0.01). The evaluation results of the specific four PVs are shown in Table Sensitivity and specificity of the Injection tool for PV occlusion verification.All patients were followed up routinely after operation, with an average follow-up of (9.90 ± 1.06) months. Follow-up standard group and KODEX group for postoperative arrhythmia recurrence and whether to continue taking antiarrhythmic drugs, the follow-up results are shown in Table Follow-up data.
