BACKGROUND: Ablation of para-Hisian accessory pathway (AP) poses high risks of atrioventricular block. We developed a pacing technique to differentiate the near-field (NF) from far-field His activations to avoid the complication. METHODS AND RESULTS: Three-dimensional mapping of the right ventricle was performed in 15 mongrel dogs and 23 patients with para-Hisian AP. Using different pacing outputs, the NF- and far-field His activation was identified on the ventricular aspect...

Myocardial perforation by pacemaker electrode is a very serious complication. Usually, the pacemaker electrode perforates the right ventricle, but rarely the left ventricular myocardium. We describe an 82-year-old female patient who presented with left ventricular pacing after temporary pacemaker implantation and was diagnosed with myocardial perforation. Emergency thoracotomy showed that the exact position of the cardiac perforation was close to the left ventricular apex. Perforation of the left ventricular free wall by an electrode sometimes progresses slowly...

We present the case of a 54 year old woman with known relapsing-remitting multiple sclerosis who presented with acute respiratory deterioration five weeks after a first course of alemtuzumab. Imaging showed bilateral ground glass changes and extensive investigations confirmed chest infection with dual pathogens - Pneumocystis jirovecii and Cytomegalovirus. She responded to standard anti-PJP and CMV therapy and was discharged on oral prophylaxis. Opportunistic infections in the weeks immediately following alemtuzumab therapy remain an uncommon complication but one that requires clinical vigilance, careful monitoring and appropriate prophylactic therapy...

OBJECTIVES: Shock wave lithotripsy (SWL) remains the only effective truly non-invasive treatment for nephrolithiasis. While single-treatment success rates may not equal those of ureteroscopy and percutaneous nephrolithotomy, it has an important role to play in the management of stones. In this paper, we outline the latest evidence-based recommendations for maximizing SWL outcomes, while minimizing complications. MATERIALS AND METHODS: A comprehensive review of the current literature was performed regarding maximizing SWL outcomes...

Colorectal cancer (CRC), gastroesophageal reflux disease (GERD), inflammatory bowel disease (IBD), and nonalcoholic fatty liver disease are considered important emerging diseases in the Asia Pacific (AP) region. The incidence rate of CRC is the highest among gastrointestinal cancers in the region surpassing that of gastric cancer. However, population CRC screening is limited by availability of adequate health resources and financing. GERD is a highly prevalent disease in AP with the prevalence of GERD symptoms and reflux esophagitis reported to be increasing...

INTRODUCTION: Cardiac pacing from the right ventricular apex is associated with detrimental long-term effects and nonapical pacing locations may be associated with improved outcomes. There is little data regarding complications with nonapical lead positions. The aim of this study was to assess long-term outcomes and lead-related complications associated with differing ventricular lead tip position. METHODS AND RESULTS: All adult patients who underwent dual-chamber pacemaker implantation from 2004 to 2014 were included if they had postprocedure chest radiographs amenable to lead position determination...

Since the first transvenous pacemaker implantation, that took place 50 years ago, important progress has been achieved in pacing technology. Consequently, today, more than 700,000 pacemakers are implanted annually worldwide. However, conventional pacemakers' implantation carries a non-negligible risk of periprocedural and long-term complications associated with the transvenous leads and pacemaker pocket. Recently, Leadless Pacing Systems have emerged as a therapeutic alternative to conventional pacing systems providing therapy for patients with bradyarrhythmias, while eliminating potential transvenous leads and pacemaker pocket related complications...

The implantation rate of cardiac implantable electronic devices has consistently increased in the last 20 years, as have the related complication rates. The most relevant issue is the removal of pacing and implantable cardioverter defibrillator (ICD) leads, which a few months after implantation tend to develop intravascular fibrosis, often making extraction a challenging and risky procedure. Areas covered: The transvenous lead extraction (TLE) scenario is constantly evolving. TLE is a key procedure in lead management strategies...

BACKGROUND: Feasibility of transfemoral (TF) transcathteter aortic valve replacement (TAVR) is limited by the smallest diameter, the calcification and tortuosity of the iliofemoral access vessels. The use of the Portico system without delivery sheath results in significantly lower profile delivery system compared to standard technique. We herein report our single center experience, feasibility and safety of such an approach. METHODS: The Portico valve was implanted sheathless in 81 high-risk patients with severe aortic stenosis utilizing percutaneous femoral access...
