Why the study?

Does intracardiac echocardiography (ICE) accurately guide balloon sizing and predict acute ablation success compared to angiography in patients undergoing cryoballoon pulmonary vein isolation for paroxysmal atrial fibrillation?

Population

22 patients undergoing pulmonary vein cryoballoon ablation for drug refractory paroxysmal atrial fibrillation.

Comparison

Intracardiac echocardiography to guide… vs PV angiography.

Design

Cohort

Discussion

Member takes

Implication

ICE total PV occlusion may predict acute cryoballoon PVI success; hypothesis-generating and requires prospective trials versus angiography.

Structured PICO

Population

22 patients (61 ± 13 years, 17 male) undergoing pulmonary vein (PV) cryoballoon ablation for drug refractory paroxysmal atrial fibrillation (total 75 PVs treated).

Intervention

Intracardiac echocardiography (ICE) to guide cryoballoon pulmonary vein isolation (assessing balloon size, placement, and occlusion).

Comparator

PV angiography (used for comparison in decision making for balloon size).

Outcome

Prediction of acute ablation success (successful PVI) based on total occlusion confirmed by ICE color flow Doppler.surrogate

Intracardiac echocardiography is a feasible nonfluoroscopic imaging technique that can accurately guide balloon sizing and predict acute success during cryoballoon pulmonary vein isolation.
