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 ablat...

introduction: intranodal pathways of atrioventricular (av) node play a vital role in the delay of conduction time in response to various atrial inputs. the present study was aimed to determine the frequency-dependent electrophysiological properties of concealed slow pathway according to a functional model of isolated rabbit atrioventricular node preparation after fast pathway ablation. methods:...

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: this study was conducted to evaluate variations in heart rate and to determine the occurrence of oculocardiac reflex (ocr) during laser in situ keratomileusis (lasik). methods: this descriptive, prospective study was designed to observe the effect of suction ring and ablation stages during lasik procedure on the heart rate. the ecg was taken before and during lasik operation on the ...

introduction: to compare endovenous laser ablation (evla) and radiofrequency ablation (rfa) in different legs in the same individual in patients with venous insufficiency. methods: sixty patients with bilateral saphenous vein insufficiency were included. evla or rfa was applied to one of the patient’s legs and rfa or evla to the other leg. results: evla and rfa complications were hyperemia at 2...

background: atrial fibrillation is a common arrhythmia in patients with rheumatic mitral and other valve diseases who are candidates for valve repair surgeries. conversion of rhythm to sinus has positive effects on quality of life and lower use of medications. the aim of this clinical study was to evaluate the effectiveness of the radiofrequency ablation maze iii procedure in the treatment of a...

background dysfunctional uterine bleeding (dub) is the most common gynecologic disorder in women of reproductive age. medical treatments are often ineffective. endometrial ablation is an alternative to hysterectomy for these women. objective to evaluate the response to treatment rate of the cavaterm tm plus technique for management of menorrhagia secondary to dysfunctional uterine bleeding (dub...

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...
