The procedural safety and efficacy of the zero-fluoroscopic approach are similar to those of conventional fluoroscopy-based ablation for atrioventricular nodal re-entrant tachycardia and atrial flutter. In the treatment of patients with refractory atrial fibrillation (AF), the safety and efficacy of atrioventricular nodal ablation (AVNA) versus pharmacotherapy alone remains unclear. The estimated mortality rate was 1 per 17 857 exposed persons. At an average age of 55.5 years and median radiation exposure of 0.38 mSv, the estimate of increased incidence was approximately 1 in 14 084. No procedure-related complications were reported. Supraventricular tachycardia (SVT), WPW Syndrome, atypical atrioventricular nodal reentry tachycardia (AVNRT), sustained monomorphic ventricular tachycardia, atrial fibrillation (AF) and atrial flutter (AFL) is generally caused by reentry mechanism. The acute success rate was 98.4% in both groups. 0 and arrhythmia recurrence was 5% and 7.9% in the CF and ZF groups, respectively. Median procedural time was 60.0 and 58.0 min, median fluoroscopy time and estimated median effective dose were 240 s vs. The atria can contract anywhere from 250-400 beats per minute, with the AV node serving as the traffic control preventing 1 to 1 conduction to the ventricles. Between May 2019 and August 2020, 123 patients were enrolled. Overview Atrial flutter, another type of supraventricular tachycardia, produces a heart rhythm with typically more atrial contractions than ventricular beats. Acute procedural parameters, increased stochastic risk of cancer incidence and 6-month follow-up data were assessed. In this prospective randomized study, patients with SVT (atrioventricular re-entrant tachycardia n = 94, typical atrial flutter n = 29) were randomly assigned in a 1:1 ratio to catheter ablation with conventional fluoroscopic guidance (CF group) or with the EnSite Precision mapping system. We aimed to assess whether exposure to ionizing radiation during catheter ablation of supraventricular tachycardia (SVT) can be completely avoided. Radiofrequency catheter ablation is considered to be standard. Interventional cardiology procedures may expose patients and staff to considerable radiation doses. It results from reentrant circuit conduction in patients with dual AV node pathway physiology. Ablation of arrhythmias, such as Wolff-Parkinson-White syndrome, AV nodal reentrant tachycardia, and atrial-fibrillation, is discussed in this review. ![]()
