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...

purpose: to study the validity and reliability of subjective refraction, predicted phoropter refraction (ppr) measured by zywave aberrometer, and final surgical plan applied for laser vision correction. methods: this prospective study was conducted on 94 myopic or myopic astigmatic eyes (48 patients) who were candidates for refractive surgery in negah eye hospital from april 2012 to july 2012. ...

atrial fibrillation is the most prevalent permanent arrhythmia. it may be associated with other cardiac pathologies which need surgical treatment. various types of surgery including the traditional cut-sew operations and operations using different energy sources are currently in use. in comparison with medical treatment, surgery is safe, effective, and has reliable results.

objective: the current study aimed to determine the efficacy of radioiodine-131 (131i) ablation therapy with thyroid hormone replacement one day before 131i administration in patients with well-differentiated thyroid cancer (dtc). methods: this retrospective study included 29 patients who underwent 131i therapies twice for dtc during 6-12 months.  since all the patients obviously had residual l...

patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. we performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ііі procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. a total of 30 pa...

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...

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...

Differentiated thyroid carcinomas usually show good uptake and response to I-131 ablative treatment. In this study, 90 patients following near total thyroidectomy who were referred to our institute for I-131 therapy are retrospectively studied. The patients are divided in two groups. Group 1 revealed complete ablation after one dose of I-131. Group 2 needed more than one dose of I-131 for...

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...

  Atrial fibrillation (AF) is associated with inflammatory and hypercoagulability state. Previous studies evaluated the safety and efficacy of dabigatran and warfarin in prevention of thrombothic complications. This study was intended to assess the influence of these drugs on hemostatic and inflammatory markers among patient underwent pulmonary vein ablation.   A total of 100 patients with AF w...
