A meta analysis of pulmonary vein isolation compared with additional ablation strategies for atrial fibrillation

BMC Cardiovascular Disorders
Background Pulmonary Vein Isolation (PVI) is considered to be the primary strategy for atrial fibrillation (AF) ablation. However, recurrence of AF and atrial tachycardia was observed to occur often after PVI, which led to the proposition of performing ...

Pulmonary vasoconstrictor action of KCNQ potassium channel blockers [PDF]

, 2006
KCNQ channels have been widely studied in the nervous system, heart and inner ear, where they have important physiological functions. Recent reports indicate that KCNQ channels may also be expressed in portal vein where they are suggested to influence ...

Multicenter retrospective database evaluation of Takotsubo syndrome in subjects undergoing catheter ablation for atrial fibrillation

Journal of Arrhythmia, 2023
Background Intracardiac catheter ablation for atrial fibrillation with pulmonary vein isolation may result in Takotsubo syndrome (TS), but the frequency, predisposing factors (age, sex, mental health disorders), and outcomes are currently unknown.

Semi-urgent pulmonary vein isolation using cryoballoon for haemodynamically unstable atrial fibrillation storm in a patient with low cardiac output syndrome: a case report

BMC Cardiovascular Disorders, 2020
Background Atrial fibrillation and heart failure are common coexisting conditions requiring hospitalisation for heart failure and death. Pulmonary vein isolation is a well-established option for symptomatic atrial fibrillation and for atrial fibrillation

A modified primary culture method of rat pulmonary vein smooth muscle cells

Journal of Cardiothoracic Surgery, 2023
Background Although the pressure of pulmonary vein increases before pulmonary artery in pulmonary hypertension due to left heart disease (PH-LHD), only a few studies have assessed pulmonary vein smooth muscle cells (PVSMCs) because of the lack of a ...

Evaluation of pulmonary vein stenosis after pulmonary vein isolation using a novel circular mapping and ablation catheter (PVAC) [PDF]

, 2011
Background—Pulmonary vein stenosis (PVST) is a well-known complication of pulmonary vein isolation (PVI). Specific anatomically designed ablation catheters for antral PVI have not been evaluated with regard to the incidence of PVST.
