Wire perforation causing cardiopulmonary arrest during radiofrequency hot balloon ablation for pulmonary vein isolation.

ABSTRACT: A 73-year-old woman underwent radiofrequency hot balloon ablation (RHBA) for paroxysmal atrial fibrillation. After delivery into the left inferior pulmonary vein (LIPV), the guidewire perforated the venous wall. We injected contrast medium while the inflated balloon occluded the PV. Subsequently, bronchial-pulmonary venous fistula (BPVF) occurred and the severe hypoxia caused pulseless electrical activity (PEA). Cardiopulmonary resuscitation and intubation quickly recovered spontaneous circulation. She was initially treated by a multidisciplinary team in the intensive care unit and subsequently discharged without sequelae. Although relatively rare, there are some reports of wire perforation during RHBA and cryoballoon ablation. Some cases resolved after discontinuing anticoagulant therapy, while others required invasive procedures. This is the first case in which hypoxia, shock, and PEA were caused by wire perforation. As such complications can occur in all balloon ablation procedures, operators need to take care when using the guidewire and guide catheter. Anticoagulant therapy should be discontinued following PV perforation, if possible. Hemostasis with ventilator management is desirable. If hemostasis cannot be achieved, lung resection must be considered. Although wire perforation causing BPVF is rare, establishment of preventive measures and treatment protocols is needed. <Learning objective: The safety of radiofrequency hot balloon (RHB) ablation for paroxysmal atrial fibrillation has been established. This case report presents the rare complication of a soft J-tipped guidewire perforating the pulmonary vein (PV) without any resistance. Pulmonary venography was performed with the RHB blocking the PV, eventually causing pulseless electrical activity from hypoxia due to a bronchial-pulmonary venous fistula. Artificial ventilation management by positive end expiratory pressure after discontinuing anticoagulant therapy was effective for hemostasis and improvement of respiratory condition.>.

Project description:BackgroundBalloon-based catheter ablation (CA) technologies, including hot balloon ablation (HBA), laser balloon ablation (LBA) and cryoballoon ablation (CBA) have been introduced in recent years as alternatives to conventional radiofrequency ablation therapy for atrial fibrillation (AF). However, the results remain controversial concerning the optimal approach. Thus, we conducted a network meta-analysis (NMA) to comprehensively evaluate the efficacy and safety of HBA, LBA and CBA.MethodsClinical trials comparing the efficacy and safety of HBA, LBA and CBA were identified through a systematic search up to October 2022. The primary outcomes of interest were the recurrence of AF and procedure-related complications.ResultsTwenty clinical trials with a total of 1,995 patients were included in the meta-analysis. The NMA results demonstrated that HBA, LBA and CBA had comparable AF recurrence rates (HBA vs. CBA: odds ratio OR = 0.88, 95% credible interval CrI: 0.56-1.4; LBA vs. CBA: OR = 1.1, 95% CrI: 0.75-1.5; LBA vs. HBA: OR = 1.2, 95% CrI: 0.70-2.0) and procedure-related complications (HBA vs. CBA: OR = 0.93, 95% CrI: 0.46-2.3; LBA vs. CBA: OR = 1.1, 95% CrI: 0.63-2.1; LBA vs. HBA: OR = 1.2, 95% CrI: 0.44-2.8). The surface under the cumulative ranking curve (SUCRA) suggested that HBA may be the optimal approach concerning the primary outcomes (SUCRA = 74.4%; 61.1%, respectively). However, HBA (40.1%) had a significantly higher incidence of touch-up ablation (TUA) than LBA (8.5%, OR = 2.8, 95% CrI: 1.1-7.1) and CBA (11.9%, OR = 3.7, 95% CrI: 1.9-7.5). LBA required more procedure time than CBA [mean difference (MD = 32.0 min, 95% CrI: 19.0-45.0 min)] and HBA (MD = 26.0 min, 95% CrI: 5.6-45.0 min), but less fluoroscopy time than HBA (MD = -9.4 min, 95% CrI: -17.0--2.4 min).ConclusionsHBA, LBA and CBA had comparable efficacy and safety as initial treatments for AF. HBA ranked highest in the primary outcomes, but at the cost of a higher incidence of TUA and longer fluoroscopy time.Systematic review registrationwww.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022381954, identifier: CRD42022381954.
