“…CB is a well-recognized and widely utilized procedure for AF ablation in Poland [3]. It has been demonstrated that this single-shot ablation was feasible and safe to perform in patients with anatomical variabilities of the LA [4]. The important role of 3D TEE in interventional cardiology has also been previously reported [5].…”

“…All patients had computed tomography with the use of contrast before the procedure. As a result, the potential benefits of NC ablation have been reduced but the current study wanted to ensure that all patients included had a typical anatomy with four separate veins [21]. In clinical practice, such an assessment can be replaced by a transesophageal echocardiography in most cases.…”

Background: Cryoballoon ablation (CBA) for atrial fibrillation (AF) is usually preceded by demonstrating pulmonary vein (PV) occlusion using contrast. The aim of the study was to determine efficacy and safety of a simplified protocol for CBA performed without demonstrating PV occlusion and compare achieved results with conventional CBA. Methods: Paroxysmal AF patients undergoing a first-time CBA were prospectively included. In the non-contrast (NC) group CBA was performed using standardized protocol without demonstrating PV occlusion. In the conventional contrast (CC) group ablations were performed after confirmation of PV occlusion. Results:The NC and CC groups comprised 51 and 22 patients, respectively. PVI according to the group assignment was achieved in 34 (67%) and 21 (95.5%) patients from the NC and CC groups, respectively (p < 0.001). In the NC group, 184 (90%) out of 204 veins were isolated without venography. There were no differences between the NC and CC groups in terms of procedure duration
