transcatheter ablation of the posteroseptal accessory pathways
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 transcathet...
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 کامل[Radiofrequency catheter ablation of left accessory pathways by transeptal approach].
OBJECTIVE To study a series of patients submitted to radiofrequency catheter ablation (RFA) of left accessory pathways (AP) using the transeptal approach (TSA) as compared to the conventional retrograde arterial approach (RAA). METHODS One hundred consecutive patients (56 male; mean age of 34.3 +/- 11 years) with 100 left APs (62 overt and 38 concealed) underwent catheter ablation using the T...

any importance to thallium data even in these young patients. Nevertheless, it is open to speculation whether this important subgroup is characterized by a special anatomical substrate' or pathophysiological mechanism leading to an extraordinarily high degree of subendocardial ischaemia. Mainly because of methodological problems, ambulatory ST-monitoring seems to be of limited value for ischaem...
متن کاملRadiofrequency ablation of a posteroseptal accessory pathway associated with two diverticula of the coronary sinus.
An electrophysiological study was performed on a 39-year-old woman with recurrent palpitations. She initially presented in 1985 with atrial fibrillation, ventricular preexcitation, and a rapid ventricular response. At that time, she underwent open heart surgery, and mapping demonstrated multiple posteroseptal and left free wall accessory pathways. Accessory pathway conduction was abolished surg...
