Journal of Arrhythmia, 2021 Pulmonary vein (PV) reconnection is the main cause of atrial fibrillation (AF) recurrence. This study aimed to examine the effect of first‐pass PV isolation (PVI) on PV reconnection frequency during the procedure and on AF ablation outcomes.

Neural Network Reconstruction of the Left Atrium using Sparse Catheter Paths [PDF]
arXiv, 2023 Catheter based radiofrequency ablation for pulmonary vein isolation has become the first line of treatment for atrial fibrillation in recent years. This requires a rather accurate map of the left atrial sub-endocardial surface including the ostia of the pulmonary veins, which requires dense sampling of the surface and takes more than 10 minutes.

Electrophysiological evaluation of pulmonary vein isolation [PDF]
Europace, 2009 Electrophysiologically demonstrated complete conduction block at the level of the veno-atrial junction is preferable as the endpoint of pulmonary vein (PV) ablation rather than circumferential periostial radiofrequency delivery. Knowledge of the individual anatomy of the PVs and the left atrium (LA), appropriate positioning of circular mapping ...

Automatic Pulmonary Artery-Vein Separation in CT Images using Twin-Pipe Network and Topology Reconstruction [PDF]
arXiv, 2021 With the development of medical computer-aided diagnostic systems, pulmonary artery-vein(A/V) separation plays a crucial role in assisting doctors in preoperative planning for lung cancer surgery. However, distinguishing arterial from venous irrigation in chest CT images remains a challenge due to the similarity and complex structure of the arteries ...

Topology Repairing of Disconnected Pulmonary Airways and Vessels: Baselines and a Dataset [PDF]
arXiv, 2023 Accurate segmentation of pulmonary airways and vessels is crucial for the diagnosis and treatment of pulmonary diseases. However, current deep learning approaches suffer from disconnectivity issues that hinder their clinical usefulness. To address this challenge, we propose a post-processing approach that leverages a data-driven method to repair the ...

What’s to come after isolation of the pulmonary veins? [PDF]
Netherlands Heart Journal, 2015 Treatment of atrial fibrillation (AF), the most prevalent tachyarrhythmia worldwide, remains a great challenge. About 15 years ago, when Haissaguerre et al. [1] first described episodes of AF triggered by focal activity originating from the pulmonary veins, the way was paved for ablative therapy of AF by pulmonary vein isolation (PVI).

How to perform pulmonary vein isolation [PDF]
EP Europace, 2004 The advent of technology for the delivery of radiofrequency energy via electrode catheters, in the late 1980s, led to the perfection of techniques for the ablation of accessory pathways and classical flutter [1–4]. This has been so successful that these substrates for arrhythmia are rarely seen in the Western world.
