Title : Laser
catheter ablation of long-lasting chronic persistent atrial fibrillation (AF)
𧩠Overview of
the Study
Dr.
Weber presented a groundbreaking method for treating long-lasting chronic persistent
atrial fibrillation (AF) using HD-Lasermapping guided laser
catheter ablation. This procedure combines precision,
safety, and efficiency, making it a promising approach for
patients with drug-resistant
AF and multiple comorbidities.
π Key
Highlights
·
Patient Profile:
o
48 patients aged 50–81 years (mean 69±7.6), including 28 women
o
All had drug-resistant AF (average 3.5 failed
antiarrhythmic therapies)
·
Methodology:
o
Interatrial septal laser puncture
using ISPunctureLas®
o
Open-irrigated laser catheter
RytmoLas® (1064nm, 15W, 10–15s per impact)
o
HD-Lasermapping
guided ablation of left and right atrial regions
o
Non-contact, tissue-specific, normothermic, non-thrombogenic
procedure
·
Clinical Outcomes:
o
96% of patients achieved sinus
rhythm long-term; most off medication
o
Repeat procedures:
31% required redo studies; all but one patient maintained sinus rhythm
o
Quality of life:
Significant improvement in all patients
o
Heart remodeling:
Left atrial dimensions decreased significantly (p<0.0001)
o
Safety:
No thrombotic complications observed
·
Conclusion:
The RytmoLas®
1064nm laser catheter represents a safe,
effective, and minimally invasive solution for chronic
persistent AF, with real-time visualization ensuring precise and targeted
ablation.
