Does a staged hybrid approach using noncontact system-guided right atrial linear lesions improve symptoms in patients with drug-resistant atrial fibrillation?
A staged hybrid approach using noncontact system-guided right atrial linear lesions achieved favorable clinical results in 75% of patients with drug-resistant atrial fibrillation.
This article describes our experience with a staged "hybrid" approach to the treatment of drug resistant AF, in which the completeness of a single linear lesion in the RA was verified with a noncontact mapping system. Inferior vena cava-tricuspid annulus ablation was performed and followed by the creation of a single intercaval lesion. The study population consisted of 24 patients with a 3.4 +/- 1.6-year history of drug resistant, severely symptomatic, lone paroxysmal (n = 19), or persistent (n = 5) AF. During a follow-up of 8 +/- 2.6 months, 12 (50%) patients remained asymptomatic and 6 (25%) had a significant decrease in AF episodes, while the arrhythmia was unchanged in 5 (21%) patients and aggravated in 1 (4%) patient. Overall, a favorable clinical result was achieved in 18 (75%) patients.
Gasparini et al. (Wed,) conducted a observational in Drug resistant atrial fibrillation (n=24). Noncontact system-guided simplified right atrial linear lesions using radiofrequency transcatheter ablation was evaluated on Favorable clinical result (asymptomatic or significant decrease in AF episodes). Noncontact system-guided simplified right atrial linear lesions using radiofrequency transcatheter ablation achieved a favorable clinical result in 75% of patients with refractory atrial fibrillation.
