We perform this meta-analysis to compare the efficacy and safety of cryoablation versus radiofrequency ablation for patients with cavotricuspid valve isthmus dependent atrial flutter. By searching EMBASE, MEDLINE, PubMed and Cochrane electronic databases from March 1986 to September 2014, 7 randomized clinical trials were included. Acute (risk ratio[RR]: 0.93; P = 0.14) and long-term (RR: 0.94;...

In the past decade, catheter ablation of atrial fibrillation (AF) has evolved as one of the most frequently performed procedures in tertiary arrhythmia centers worldwide. With the observation of the actively firing trigger originating from within the pulmonary veins (PVs), ablation strategies have focused at least in paroxysmal AF patients on complete isolation of the PVs. Several different abl...

a therapeutic option for patients with tachyarrhythmias mediated by an accessory atrioventricular pathway. The technique conventionally implies the introduction of several catheters into the heart for assessment of electrophysiological parameters as well as for localization of the accessory pathway and may last for several hours. Methods and Results. Thirty-four patients with Wolff-Parkinson-Wh...

The utility of selective radiofrequency catheter ablation of the slow pathway for the treatment of common and uncommon atrioventricular nodal reentrant tachycardia (AVNRT) was studied in 110 consecutive patients, 94 with slow-fast form common AVNRT, and 11 and 5, respectively, with the fast-slow and slow-slow forms of uncommon AVNRT. Ablation sites were determined by mapping a late and spiky "s...

Radiofrequency catheter ablation is an interventional procedure used to treat arrhythmia. An electrode that could inject saline has been developed prevent steam pop on heart tissue during radiofrequency ablation. Thus, we investigated numerical model the effect of injection and tissue’s deformation. In this study, hyperelastic was implemented analyze deformation due catheter’s contact force. Be...

OBJECTIVES The aim of this study was to assess the clinical characteristics and the efficacy of radiofrequency catheter ablation (RFCA) for idiopathic ventricular fibrillation (VF) and/or polymorphic ventricular tachycardia initiated by ventricular extrasystoles originating from the right ventricular outflow tract (RVOT). BACKGROUND Ventricular fibrillation and/or polymorphic ventricular tach...

Introduction Iliofemoral venous occlusions may sometimes be encountered in patients with congenital heart disease (CHD), because of repeated catheterizations, a cut-down of the femoral vein, insertion of central venous catheters, or surgical venous anastomoses. Consequently procedures for catheter intervention, including catheter ablation, may sometimes become difficult or impossible because of...

OBJECTIVE To determine the outcome of Radiofrequency Catheter Ablation (RFCA) as a non-pharmacological curative therapy for idiopathic Ventricular Tachycardia (VT) and to identify procedure-related complications. STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY The Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from February 2001 to Oct...

Accurate and stable positioning of the ablation catheter tip during the delivery of radiofrequency impulses in cardiac electrophysiology remains a challenge due to the endocardium motion from multiple sources (cardiac cycle and respiration) and inevitable slippage of the catheter tip. This paper presents a novel ablation catheter guidance framework during electrophysiology procedures. Catheter ...
