background chronic sacroiliac (si) joint pain constitutes 16% to 30% of the total prevalence of chronic low back pain, which is commonly unilateral. apart from conservative management, various interventional pain management procedures have been reported. intraarticular deposteroid injection has been described as the most evidence-based, but different various radio frequency (rf) procedures have...

introduction: green light photo selective vaporization of the prostate (pvp) is a minimally invasive method of treatment for clinical benign prostatic hyperplasia with fewer side effects. the aim of this study is to evaluate the safety, effectiveness and cost analysis of pvp compared with transurethral resection of prostate. methods: a systematic search was done in cochrane, trip database, medl...

background: monozygotic monochorionic triplet pregnancy with conjoined twins is a very rare condition and is associated with many complications. case: in this study, we describe a monochorionic–diamniotic triplet pregnancy after in vitro fertilization with an intracytoplasmic sperm injection. at a gestational age of 6 weeks and 4 days of pregnancy one gestational sac was observed, and at a gest...

Catheter ablation is an effective treatment for atrial fibrillation (AF). However, over long-term follow-up, it is becoming clear that AF often recurs and repeat ablation is required. With the goal of improving efficacy, particularly in those patients with risk factors for poor outcomes using a standard endocardial ablation technique, surgical epicardial ablation has emerged as an alternative m...

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 ...

Atrial fibrillation (AF) is a multifactorial disease with complex pathophysiology. Although restoring sinus rhythm delays the progression of atrial remodeling, non-pharmacologic intervention, such as radiofrequency catheter ablation (RFCA), should be done based on the background pathophysiology of the disease. While circumferential pulmonary vein isolation (CPVI) has been known to be the corner...

Despite advances in catheter ablation of patients with persistent atrial fibrillation (AF), the ideal ablation strategy still is in evolution. It is known, however, that these patients fare poorly with pulmonary vein (PV) isolation alone.1 In an effort to improve outcomes, potential mechanisms of AF beyond the PVs have been targeted by left atrial linear ablation,2,3 ablation of complex fractio...

BACKGROUND The MRI-compatible electrophysiology system previously used for MR-guided left ventricular electroanatomic mapping was enhanced with improved MR tracking, an MR-compatible radiofrequency ablation system and higher-resolution imaging sequences to enable mapping, ablation, and ablation monitoring in smaller cardiac structures. MR-tracked navigation was performed to the left atrium (LA)...
