Abstract

The role of balloon catheters in patients with persistent forms of atrial fibrillation (AF) remains ill defined. We therefore sought to assess the safety and efficacy of a laser balloon (LB)-guided pulmonary vein isolation (PVI) in consecutive all-comers with persistent AF. All patients undergoing an LB-guided PVI procedure for persistent AF between January 2011 and December 2012 were matched to patients undergoing circumferential PVI using irrigated radiofrequency (RF) current ablation for date of procedure, age, gender, AF duration, left atrial (LA) size, and left ventricular ejection fraction. The primary endpoint was freedom from AF between 90 and 365 days post-ablation after a single procedure. Eighty patients (mean age 66 ± 9; 71% male) with a median (Q1-Q3) AF episode duration of 2 (1-3) months underwent successful PVI in the two groups. The primary endpoint of 1-year single procedure AF/atrial tachycardia (AT) recurrences was reached by 11/40 (27.5%) patients in the LB group and in 9/40 (22.5%) patients in the RF group (P = 0.87). During a mean follow-up of 517 ± 170 days, 13 (32.5%) and 16 (40%) patients in the LB and RF groups, respectively, experienced AF/AT recurrences (P = 0.64). Procedural complications occurred i...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
