Clinical Trial: Procedural Mitral Isthmus Block Durability After Pulsed-Field Ablation in Patients with Non-Paroxysmal Atrial Fibrillation

U.S., Feb. 1 -- ClinicalTrials.gov registry received information related to the study (NCT06803238) titled 'Procedural Mitral Isthmus Block Durability After Pulsed-Field Ablation in Patients with Non-Paroxysmal Atrial Fibrillation' on Jan. 27.

Brief Summary: Mitral isthmus is one of the targets for the catheter ablation of non-paroxysmal atrial fibrillation (AF), in which pulmonary veins isolation alone is not deemed sufficient. Typically, lateral mitral isthmus ablation line is performed from the mitral annulus to the ostium of the left inferior pulmonary vein or to the posterior base of the left atrial appendage. When conduction block across the mitral isthmus is achieved, the standard practice using radiofrequency energy is to wait 20 m...
