“…These outcomes illustrate that radiofrequency ablation surgery can effectively treat the patients with AF by regulating the pulmonary veins. Retrospective clinical studies by Shroff et al and Kumagai suggest that the A/N value of adenoid hypertrophy in patients with OSAHS are significantly decreasing [Kumagai 2022;Shroff 2021]. The results are consistent with those reported in previous studies.…”

This study aimed to investigate electrophysiological features of radiofrequency ablation surgery in patients with the atrial fibrillation (AF). Fifty patients were included in this study and evenly divided, with 25 AF patients in the experiment group and 25 patients with arrhythmias in the control group. General clinical materials in the two groups were collected. Then, patient number of pulmonary vein antrum potential trial, intra-right atrial conduction time, intra-left atrial conduction time, interatrial conduction time, conduction time between atrium, and pulmonary veins trials were utilized to measure the efficacy of radiofrequency ablation surgery in patients with AF and clarify the relationship between AF and electrophysiological features in the atrium and pulmonary veins. Our study findings showed that conduction time interval between the atrium and pulmonary veins trial by radiofrequency ablation surgery were significantly less than those in pre-treatment AF patients. We can conclude that radiofrequency ablation surgery can effectively treat AF patients by relieving the electrophysiological dysfunction, and radiofrequency ablation can be used to prevent the development of AF.

“…Early ablative techniques, which targated focal ablation directly within the venous ostia have demonstrated an increased incidence of pulmonary vein stenosis. Improved understanding of risk factors for pulmonary vein stenosis and adoption of newer ablation techniques like circumferential ablation and antral isolation have led to substantial reduction in pulmonary vein stenosis [ 65 ].…”

This umbrella review synthesizes data from 17 meta-analyses investigating the comparative outcomes of catheter ablation (CA) and medical treatment (MT) for atrial fibrillation (AF). Outcomes assessed were mortality, risk of hospitalization, AF recurrence, cardiovascular events, pulmonary vein stenosis, major bleeding, and changes in left ventricular ejection fraction (LVEF) and MLHFQ score. The findings indicate that CA significantly reduces overall mortality and cardiovascular hospitalization with high strength of evidence. The risk of AF recurrence was notably lower with CA, with moderate strength of evidence. Two associations reported an increased risk of pulmonary vein stenosis and major bleeding with CA, supported by high strength of evidence. Improved LVEF and a positive change in MLHFQ were also associated with CA. Among patients with AF and heart failure, CA appears superior to MT for reducing mortality, improving LVEF, and reducing cardiovascular rehospitalizations. In nonspecific populations, CA reduced mortality and improved LVEF but had higher complication rates. Our findings suggest that CA might offer significant benefits in managing AF, particularly in patients with heart failure. However, the risk of complications, including pulmonary vein stenosis and major bleeding, is notable. Further research in understudied populations may help refine these conclusions.

“…PVS commonly occurs several months after CA and presents with non-specific respiratory symptoms, such as dyspnea, cough, chest pain and hemoptysis (4). Furthermore, chest radiography and computed tomography (CT) show nonspecific parenchymal opacities (5)(6)(7)(8)(9)(10). Accordingly, the diagnosis of PVS is often delayed or entirely missed, given the long interval from CA to the onset and the lack of symptomatic specificity and imaging characteristics (5)(6)(7)(8)(9).…”

Accordingly, the diagnosis of PVS is often delayed or entirely missed, given the long interval from CA to the onset and the lack of symptomatic specificity and imaging characteristics (5)(6)(7)(8)(9). Such delays in diagnoses have been associated with major adverse events related to the progression of stenosis as well as severe parenchymal lung damage (11).…”

Pulmonary vein stenosis (PVS) is a serious complication of catheter ablation (CA) for atrial fibrillation (AF). PVS generally occurs several months after CA and presents with non-specific symptoms and imaging findings. There have been reports of delayed diagnoses due to a misdiagnosis as infection, interstitial pneumonia, or organizing pneumonia. We introduced six cases of PVS after CA, all of which showed narrowing of the unilateral pulmonary vessels with or without lobar volume loss in the left lung on unenhanced computed tomography. We report these findings as important results indicating the possibility of PVS after CA for AF and contributing to the early diagnosis and management of PVS.
