conclusions: catheter ablation of flutter circuit will not prevent later manifestation of af in 16% of the patients undergoing catheter ablation of the typical afl. bmi was the only independent predictor of af following catheter ablation of the typical afl. objectives; to determine long-term incidence and predictors of af after catheter ablation of typical afl. material and methods: between mar...

the use of diagnostic and therapeutic methods for assessing pulmonary vein due to its status as a main source of ectopic beats for the initiation of atrial dysrrythmias is strongly recommended.   we report the case of a 13-year-old girl who was admitted to our hospital with the electrocardiogram manifestation of an ectopic atrial tachycardia. the focus of arrhythmia was inside the right upper p...

contexts hepatocellular carcinoma (hcc) is one of the most common malignant diseases in the world. because less than 20% of patients with hcc are resectable, various types of non-surgical treatment have been developed. evidence acquisition at present, radiofrequency ablation (rfa) is accepted as the standard local treatment for patients with hcc because of its superior local control and overall...

background: catheter ablation is widely used for treatment of atrial fibrillation. the use of fluoroscopic and non-fluoroscopic mapping systems in catheter ablation is common. this study conducted to investigate the safety and effectiveness of navx non-fluoroscopic mapping system.   methods : in this study, the appropriate electronic databases including cochrane library and ovid medline searche...

background: about half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (af). cox described the surgical cut-and-sew maze procedure, which is an effective surgical method but has some complications. this study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (rfa) for patients undergoing mitral valve surgery with af. metho...

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...

background: radiofrequency catheter ablation (rfca) has been introduced as the treatment of choice for supraventricular tachycardia. the aim of this study was to evaluate the success rate as well as procedural and in-hospital complications of rfca for the treatment of atrioventricular nodal reentrant tachycardia (avnrt).   methods: between march 1995 and february 2009, 544 patients (75.9 % fema...

catheter ablation is an accepted, highly effective modality of treatment for cardiac arrhythmias in children. the success rate depends on the operator’s experience, especially in cases involving complex anatomies. we hereby report our recent experience of successful ablation of accessory pathways in three children with complex congenital heart diseases. the first case was a 7-year-old girl with...

background: complete atrioventricular block (av block) is a serious complication of slow pathway ablation therapy in the treatment of atrioventricular nodal re-entrant tachycardia (avnrt).   the present study was aimed at determining whether the electroanatomical pace mapping of koch’s triangle could significantly improve the safety, efficiency, and efficacy of selective slow pathway ablation i...
