Vein Stenosis

Pulmonary vein stenosis is a well-established possible complication following an atrial fibrillation ablation of pulmonary veins. Symptoms of pulmonary vein stenosis range from asymptomatic to severe exertional dyspnea. The number of asymptomatic patients with pulmonary vein stenosis is greater than originally estimated; moreover, only about 22% of severe pulmonary vein stenosis requires intervention. We present a patient with severe postatrial fibrillation (AF) ablation pulmonary vein (PV) stenosis, which was seen on multiple imaging modalities including cardiac computed tomography (CT) angiogram, lung perfusion scan, and pulmonary angiogram. This patient did not have any pulmonary symptoms. Hemodynamic changes within a stenosed pulmonary vein might not reflect the clinical severity of the obstruction if redistribution of pulmonary artery flow occurs. Our patient had an abnormal lung perfusion and ventilation (V/Q) scan, suggesting pulmonary artery blood flow redistribution. The patient ultimately underwent safe repeat atrial fibrillation ablation with successful elimination of arrhythmia.

The first use of cryoablation in the treatment of arrhythmia has already been described over 40 years ago [1]. Since the introduction of cryoballoon in pulmonary veins isolation in atrial fibrillation treatment, the method has started to attract a lot of interest. Over 350,000 procedures around the word were carried out only by 2018 [2]. Recently, there have been several new publications on the results of second-generation cryoballoon ablation [2, 3, 4]. In view of technology changes, and to summarize years of experience in the treatment of atrial fibrillation, the first Cryousers conference was organized, and held in 2018 in Poland. During this meeting a survey was conducted, obtaining data on the practice of atrial fibrillation treatment in 38 Polish electrophysiological centers performing cryoablation of atrial fibrillation using both balloons, Arctic Front Advance, Medtronic Inc., Minneapolis MN, and radiofrequency point by point ablation. Around 3,745 cryoballoon procedures were performed in the surveyed centers during the year preceding the survey. The survey concerned practical issues related to the qualification and preparation of patients for the procedure, its course, and the results of pulmonary veins isolation in Poland.

Objective: Intraoperative CARTO Mapping for Atrial Fibrillation ablation in cardiac surgery. Background: Surgical ablation of Atrial Fibrillation is usually performed without mapping. The study aims to determine if intraoperative CARTO can be useful to guide the ablating procedure. Methods and Findings: Fourteen patients with symptomatic and drug-refractory concomitant AF were operated on in 2003 and 2004. CARTO mapping was performed before and after surgical bipolar radio-frequency ablation. Application of energy was repeated when residual electrical activity was detected at the pulmonary veins-atrial junction. Pacing wires were applied on right and left pulmonary veins distally to the ablation line to confirm the exit block. The mapping protocol was completed in 12 patients. Acute left atrium-pulmonary vein isolation was achieved after single or double energy application in 2/12 (16.6%) and 9/12 (75%) patients, respectively. The mean duration of the mapping and ablation procedure was 67 minutes. At discharge, PV isolation persisted in 10 patients: exit block was confirmed by the absence of pacing through the pulmonary veins electrodes. After a mean follows up of 181 months, no further recurrent AF events were registered in 9/12 (69.2%) patients. Conclusions: CARTO system is useful during open-heart surgery to guide the ablating strategy.
