conclusions we can conclude that treatment of af using a right-sided minithoracotomy approach and rf energy in patients undergoing cardiac surgery for various valve diseases is feasible, safe, and reproducible. objectives our aim is to evaluate the feasibility, safety, and immediate plus medium-term results of concomitant af ablation therapy in patients undergoing minimally invasive valve surge...

av-node modification by catheter rf energy delivery is treatment of choice in the symptomatic patients with avnrt. this study included 30 patients with avnrt (19 women, 11 men). we did slow pathway ablation in 29 cases successfully. maximum effective energy delivery was 40 watts for 40 msec. 1:1 av conduction increased from 290±40 msec before ablation to 340±65 msec after ablation. also av-node...

accessory pathways (ap) are abnormal myocardial connections between atria and ventricles with electrical conductive properties. we performed radio frequency (rf) catheter ablation in 66 patients with manifest ap at dr.shariati hospital during 5 years. bipolar mapping was used in 48 patients and unipolar mapping in 18 patients of find the best site for rf energy delivery. we calculated total dur...

background: energy deficit is a common and serious problem in pediatric intensive care units. parenteral nutrition, either alone or in combination with enteral nutrition, can improve nutrient delivery in critically ill patients by preventing or correcting the energy deficit and improving the outcomes. intralipid 10% and 20% are lipid emulsions, widely used in parenteral nutrition. despite sever...

background: after radiofrequency catheter ablation of arrhythmias, patients have to bed rest for 4-6 h to prevent bleeding and hematoma. however, such a rest may cause back pain in the patients. the aim of this study was to determine the effects of continuous change in body position during and after the radiofrequency ablation on the back pain. materials and methods: in a quasi‑experimental des...

In this retrospective study of 22 patients with the Wolff-Parkinson-White (WPW) syndrome, the cost of catheter ablation in 11 patients was compared with that of surgical ablation in another 11 patients. All patients in the catheter ablation group had a posteroseptal accessory pathway; in the surgical group, 5 patients had a left lateral accessory pathway, 3 had a left lateral and posteroseptal ...

Catheter ablation of atrial fibrillation (AF) is now an important therapeutic modality for patients with AF. There is considerable evidence available from several prospective randomized trials demonstrating that catheter ablation of AF is superior to antiarrhythmic drug therapy in controlling AF and that AF ablation improves quality of life substantially. This is especially true for patients wi...

INTRODUCTION No prior studies have quantitatively analyzed the characteristics of bipolar or unipolar electrograms that may be helpful in identifying successful ostial ablation sites in patients with atrial fibrillation undergoing segmental pulmonary vein isolation. METHODS AND RESULTS The characteristics of bipolar and unipolar electrograms recorded at 185 successful and 120 unsuccessful ost...

Background: Catheter and cryoballoon ablation are established treatments for atrial fibrillation. Frequently, substrate modification of the left atrium is performed in patients with persistent AF or evidence of left atrial adverse remodeling. We compared one year outcomes of AF ablation with substrate modification utilizing radiofrequency catheter ablation (RFA) compared to a combination of cry...

Radiofrequency catheter ablation of atrial fibrillation (AF) is an effective rhythm control strategy, and its efficacy has been proved to be superior to anti-arrhythmic drugs.1-3) Recently, the European Society of Cardiology’s 2010 revised guidelines for AF management suggested catheter ablation as the firstline treatment in patients with paroxysmal lone AF.4) When Haissaguerre et al.5) initial...
