Isolated pulmonary vein atresia. [PDF]

Heart, 1990
Two patients with isolated atresia of the pulmonary veins are described. One patient presented with haemoptysis and the other with recurrent unilateral chest infections. The diagnosis was confirmed in both instances by cardiac catheterisation and pulmonary angiography. One patient died one year after the diagnosis was made and the second child has been

90 vs 50-Watt Radiofrequency Applications for Pulmonary Vein Isolation: Experimental and Clinical Findings

Circulation: Arrhythmia and Electrophysiology, 2022
Background: Fifty-watt radiofrequency applications have proven to be safe and efficient for pulmonary vein isolation (PVI). However, as PV reconnection still occurs and ablation catheter instability significantly contributes to suboptimal lesion ...

Ultrasonic characterization of the pulmonary venous wall: echographic and histological correlation [PDF]

, 2002
Background: Pulmonary vein isolation with radiofrequency catheter ablation techniques is used to prevent recurrences of human atrial fibrillation. Visualization of the architecture at the venoatrial junction could be crucial for these ablative techniques.

Very High-Power Ablation for Contiguous Pulmonary Vein Isolation: Results From the Randomized POWER PLUS Trial.

JACC Clinical Electrophysiology, 2022
BACKGROUND Very high-power, short-duration (90-W/4-second) ablation for pulmonary vein isolation (PVI) may reduce procedural times. However, shorter applications with higher power may impact lesion quality.

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 ...
