To Editor The ablation of atrioventricular nodal reentrant tachycardia (AVNRT) using cryoablation has emerged as a viable alternative to radiofrequency (RF) ablation due to its reduced risk of inducing permanent atrioventricular block. However, this technique necessitates specific procedural considerations to minimize the recurrence of arrhythmias. The authors conducted a comparative analysis of clinical outcomes between cryoablation and conventional RF ablation, demonstrating that cryoablation was associated with reduced fluoroscopy time and was non-inferior to RF ablation in terms of efficacy and […]

Abstract Background The ablation of atrioventricular nodal reentrant tachycardia (AVNRT) with cryoablation is an alternative to radiofrequency (RF) ablation in patients due to the low risk of total atrioventricular block. An increase in early-late recurrences after cryoablation is reported as an important disadvantage. Objectives In this study, we aimed to compare the acute procedural success and the long-term recurrence rates of patients, with AVNRT who underwent methods. Methods 73 patients with AVNRT were included in the study: 32 with cryoablation […]

Abstract Background: Atrial fibrillation frequently affects patients with valvular heart disease. Ablation of atrial fibrillation during valvular surgery is an alternative for restoring sinus rhythm. Objectives: This study aimed to evaluate mid-term results of successful atrial fibrillation surgical ablation during valvular heart disease surgery, to explore left atrium post-ablation mechanics and to identify predictors of recurrence. Methods: Fifty-three consecutive candidates were included. Eligibility criteria for ablation included persistent atrial fibrillation
