transcatheter ablation of the posteroseptal accessory pathways

چکیده
transcatheter ablation of atrioventricular accessory pathway is the therapy of choice in symptomatic patients. the ablation of posteroseptal accessory pathways thas some important points due to its anatomical location. catheter ablation of posteroseptal accessory pathways via left side approach is time consuming with low success rate and higher complications. we performed successful transcatheter radio frequency ablation of posteroseptal accessory pathways in 25 patients. this was done via right atrial approach in 23 cases and left side approach in 2 cases.

Transcatheter electrical ablation of accessory pathways in children.
Supraventricular tachycardia (SVT), the most common sustained symptomatic arrhythmia of childhood, is often supported by a manifest or concealed accessory pathway. Permanent interruption of the accessory pathway usually requires surgical division. Recent experience with electrical ablation of posterior septal pathways in adults prompted us to apply the technique to children. Six children, ages ...
متن کاملEfficacy and safety of transcatheter ablation of posteroseptal
Eight patients with a posteroseptal accessory pathway and symptomatic atrial fibrillation and/or orthodromic reciprocating tachycardia underwent attempted transcatheter ablation of the accessory pathway. A quadripolar electrode catheter was positioned within the coronary sinus such that the proximal pair of electrodes straddled the os. This proximal pair of electrodes was made electrically comm...

R ecognition of the possibility of ablating cardiac tissue by means of commonly used electrophysiological catheters has led to the development of the fulguration techniques. Unipolar DC (direct current) shocks delivered at the tip of a catheter by means of an ordinary defibrillator were applied to the atrioventricular node-His bundle area for control of refractory supraventricular tachycardias....
متن کاملCatheter Ablation of Accessory Pathways
Background. Animal studies have suggested that the temperature of the electrode-tissue interface during radiofrequency catheter ablation accurately predicts lesion size. The purpose of the current study was to evaluate the utility of continuous temperature monitoring during radiofrequency catheter ablation in patients with Wolff-Parkinson-White syndrome. Methods and Results. Twenty patients wit...
متن کاملRisk of coronary artery injury with radiofrequency ablation and cryoablation of epicardial posteroseptal accessory pathways within the coronary venous system.
BACKGROUND Ablation of epicardial posteroseptal accessory pathways requires ablation within the coronary venous system. We assessed the risk of coronary artery (CA) injury with radiofrequency ablation (RFA) within the coronary venous system as a function of the distance between the CA and ablation site. We also examined the efficacy and safety of cryoablation close to a CA. METHODS AND RESULT...
متن کاملCoronary sinus-ventricular accessory connections producing posteroseptal and left posterior accessory pathways: incidence and electrophysiological identification.
BACKGROUND The coronary sinus (CS) has a myocardial coat (CSMC) with extensive connections to the left and right atria. We postulated that some posteroseptal and left posterior accessory pathways (CSAPs) result from connections between a cuff of CSMC extending along the middle cardiac vein (MCV) or posterior coronary vein (PCV) and the ventricle. The purpose of the present study was to use CS a...
