Résumé
Catheter ablation in adult congenital heart disease (ACHD) patients is a critical treatment strategy for complex arrhythmias including atrial fibrillation (AF) and atrial tachycardia (AT). In addition to vitamin K antagonists (VKAs), direct oral anticoagulants (DOACs) are increasingly used in this patient population. The purpose of this study was to assess the safety of catheter ablation in ACHD patients on uninterrupted oral anticoagulation with VKA or DOAC, examining thromboembolic, bleeding, and vascular access complications. Retrospective analysis of 234 ACHD patients with simple (n = 83), moderate (n = 66), or complex (n = 85) CHD (mean age 46 years) undergoing 368 ablation procedures on uninterrupted oral anticoagulation with VKA (45.4%) or DOAC (54.6%) was undertaken. Arrhythmias were AF in 97, right AT in 181, left AT in 65, or a combination of AF and AT in 25. No thromboembolic complications occurred. Major complications occurred in 4 patients (1.1%; 1 VKA, 3 DOAC), including retroperitoneal hematoma in 2 and arteriovenous (AV) fistula requiring surgical treatment in 2. Minor bleeding or vascular access complications occurred in 46 cases (12.5%), including hematomas >5 cm in 26, AV fistulas (not requiring surgical intervention) in 13, and pseudoaneurysms in 7 (thrombin injection in 3/7). Overall, no significant difference was found between DOAC (14.9%) and VKA groups (12.0%; P = .411). Catheter ablation in ACHD patients on uninterrupted oral anticoagulation with VKA or DOAC is feasible and safe. No thromboembolic events occurred, and major bleeding or vascular access complications were rare. No significant differences regarding minor bleeding or vascular access complications between patients on DOAC or VKA were found.

BACKGROUND
Catheter ablation in adult congenital heart disease (ACHD) patients is a critical treatment strategy for complex arrhythmias including atrial fibrillation (AF) and atrial tachycardia (AT). In addition to vitamin K antagonists (VKAs), direct oral anticoagulants (DOACs) are increasingly used in this patient population.
OBJECTIVE
The purpose of this study was to assess the safety of catheter ablation in ACHD patients on uninterrupted oral anticoagulation with VKA or DOAC, examining thromboembolic, bleeding, and vascular access complications.
METHODS
Retrospective analysis of 234 ACHD patients with simple (n = 83), moderate (n = 66), or complex (n = 85) CHD (mean age 46 years) undergoing 368 ablation procedures on uninterrupted oral anticoagulation with VKA (45.4%) or DOAC (54.6%) was undertaken. Arrhythmias were AF in 97, right AT in 181, left AT in 65, or a combination of AF and AT in 25.
RESULTS
No thromboembolic complications occurred. Major complications occurred in 4 patients (1.1%; 1 VKA, 3 DOAC), including retroperitoneal hematoma in 2 and arteriovenous (AV) fistula requiring surgical treatment in 2. Minor bleeding or vascular access complications occurred in 46 cases (12.5%), including hematomas >5 cm in 26, AV fistulas (not requiring surgical intervention) in 13, and pseudoaneurysms in 7 (thrombin injection in 3/7). Overall, no significant difference was found between DOAC (14.9%) and VKA groups (12.0%; P = .411).
CONCLUSION
Catheter ablation in ACHD patients on uninterrupted oral anticoagulation with VKA or DOAC is feasible and safe. No thromboembolic events occurred, and major bleeding or vascular access complications were rare. No significant differences regarding minor bleeding or vascular access complications between patients on DOAC or VKA were found.
