Results of a survey concerning atrial fibrillation ablation strategies in Poland.

Background: Catheter ablation is an effective treatment for patients with atrial fibrillation (AF). Despite the increasing availability of the procedure, current treatment patterns of invasive AF treatment in Poland are unknown.

Aims: The aim of the study was to assess data on the contemporary approaches to AF ablation in Poland, such as: target population, patients' characteristics, ablation techniques, procedural results, and complication rates.

Does the origin of ablated premature ventricular contractions determine the level of left ventricular function improvement?

Background: Premature ventricular contractions (PVCs) are associated with tachycardiomyopathy and high mortality rate. The treatment depends on the engaged ventricle. For PVCs originating from the right outflow tract (OT), radiofrequency catheter ablation (RFCA) is recommended (class IB‑R recommendation) in preference to pharmacotherapy.

The effect of radiofrequency catheter ablation of frequent premature ventricular complexes and arrhythmia burden on left ventricular function.

Background: Frequent premature ventricular complexes (PVC) are related to reversible tachycardia-induced cardiomyopathy. However, the role of arrhythmia burden on the outcome of the catheter ablation has not been fully recognised.

Aim: The aim of this study was to assess the effect of catheter ablation and PVC burden in patients with and without structural heart disease (SHD) on left ventricular ejection fraction (LVEF).

Initial experience in ablation of typical atrial flutter using a novel three-dimensional catheter tracking system.

Aims: Three-dimensional (3D) mapping has been established for clinical routine in an interventional electrophysiology (EP). Recently, a novel sensor-based 3D catheter tracking system has been introduced integrating 3D non-fluoroscopic catheter navigation into the environment of pre-recorded 2D fluoroscopy [MediGuide™ Technology (MG)]. We are reporting on the first clinical experience for ablation of typical atrial flutter.
