Reversible mechanical atrioventricular block during cryoablation for paroxysmal atrial fibrillation with a 28 mm balloon
Résumé
Cryoablation of paroxysmal atrial fibrillation is an increasingly common procedure for treatment of symptomatic patients after failure of or intolerance to antiarrhythmic drug therapy. Atrioventricular (AV) block during cryoablation therapy is an uncommon complication. We present a case of a transient mechanical AV block occurring during manipulation of a 28 mm cryoballoon catheter before cryoenergy delivery around the right inferior pulmonary vein (RIPV). The main hypothesis is a mechanical bump of the AV node.
