The upper pulmonary veins (PVs) are responsible for the majority of atrial fibrillation (AF) triggering foci, whereas the inferior PVs are more difficult to ablate and prone to postablation ostial ...

A majority of cases of atrial fibrillation originate within the pulmonary veins. Ablation of atrial fibrillation, also known as “pulmonary vein isolation” or PVI, electrically disconnects the ...

These foci are commonly in the superior pulmonary veins; this is an important factor in the electrophysiologic approach to atrial fibrillation, known as pulmonary vein isolation. Less commonly ...

Under a canopy of eight heart-monitoring screens in a cardiac catheterization lab on a recent Monday, Mayo Clinic doctors briefly paused a procedure treating atrial fibrillation to inspect a new tool: ...

Pulse Biosciences is developing nsPFA technology for cardiac ablation to treat AFib and for ablating benign thyroid nodules.

For people with atrial fibrillation (Afib or AF), stopping ... even if largely confined to the pulmonary veins," Chu explained. "Additionally, "AF is now understood to be a progressive condition ...

The system, which has received CE Mark approval in Europe, adds to an increasingly crowded field of PFA technologies.

"Our results provide conclusive evidence for the benefit of pulmonary vein isolation ablation in individuals with symptomatic atrial fibrillation, putting concerns about a substantial placebo ...

The study subjects were 51 consecutive patients with highly symptomatic permanent (n = 25) or persistent (n = 26) atrial fibrillation resistant to, or intolerant of, drug therapy. Atrial ...

The pulse frequency is faster and reduces the risk of injury to the surrounding tissue, including the esophagus, which is close to where Wright's AFib was in the pulmonary veins. The radio ...

Pulmonary vein isolation is widely recognised as a highly effective and minimally invasive technique for managing AFib, reducing symptoms, and lowering the risk of complications such as stroke and ...
