Introduction
Biophysics of bipolar radiofrequency catheter ablation (Bi-RFCA) suggest more condensed and selective lesion formation when compared to conventional-unipolar approach. Whether more selective Bi-RFCA can result in safe and effective ablation of arrhythmic substrates in close proximity of His bundle has not been investigated so far.
Pur...
Background
Radiofrequency ablation (RFA) of ventricular arrhythmias (VAs) arising from the inaccessible basal region of the left ventricular summit (LVS) is challenging due to proximity to coronary vessels, epicardial fat and poor RF delivery within the distal coronary venous system.
Objective
We describe the outcomes of an anatomical approach for...
When arrhythmia originates from the His bundle (HB) area conventional radiofrequency catheter ablation (RFCA) is associated with increased risk of atrioventricular block (AVB). Biophysics of bipolar RFCA (Bi-RFCA) suggest more selective lesion formation. It has been shown that Bi-RFCA can be an alternative in case of premature ventricular complex (...
Background:
Data on feasibility of ultrasound-guided venous access (USG-VA) for catheter ablation (CA) and electrophysiological studies (EPS) in large cohorts are scarce. The impact of Valsalva maneuver (VM), which can increase the diameter of femoral vein (FV), on USG-VA is unknown.
Aims:
To determine impact of VM on FV diameters during USG-VA...
Background
Radiofrequency catheter ablation (RFCA) of premature ventricular complexes (PVC) and ventricular tachycardia (VT) can be an effective method of treatment. However, when arrhythmia originates from the left ventricular summit (LVS), an ablation performed with conventional unipolar energy sources can be challenging and may require alternati...
Introduction
Bipolar radiofrequency catheter ablation (Bi‐RFCA) emerged as an option for treatment of arrhythmias resistant to conventional approach. Data on safety issues of Bi‐RFCA, including temperature values of intracardiac return electrode (IRE) are lacking.
Objective
To determine safety profile of Bi‐RFCA regarding temperature measurements...
Objective
The aim of this study was to evaluate cardiac autonomic nervous system function using Holter-derived and standard electrocardiographic parameters in patients with myotonic dystrophy (dystrophia myotonica, DM) and no clinically overt heart involvement. Methods
Eighty-four DM patients without conditions potentially influencing cardiac auton...
