BACKGROUND: The understanding of spontaneous scar based reentrant atrial arrhythmia is limited. We aim to characterize the electrophysiologic and mapping features of spontaneous scar based atrial flutter (AFL) and outcomes of catheter ablation. METHODS: Consecutive patients with a diagnosis of AFL who underwent catheter ablation from Jan 2012 to Jun 2015 were screened. Scars were detected in 12 patients and were included in this study. All had negative coronary angiography...

End-stage heart failure (HF) frequently needs continuous inotropic support in hospital and has high morbidity and mortality in absence of heart transplantation. This study reports outcome, efficacy, and safety of continuous ambulatory inotropes (AI) and/or periodic levosimendan (LS) infusions in pediatric HF patients. The study included 27 patients, median age 9.4 (0.1-26.1) years, with severe HF (6 myocarditis, 13 dilated cardiomyopathy, 2 restrictive cardiomyopathy, 6 repaired congenital heart disease). Dobutamine and milrinone AI were administered in 21 patients through a permanent central catheter for median duration 1...

PURPOSE: Radiofrequency current energy (RFC) ablation is still considered as the gold standard for atrioventricular nodal reentrant tachycardia (AVNRT). Success-rates for AVNRT ablation vary irrespective of the ablation technology and strategy. This study aimed to access safety, efficacy, and long-term outcome of RFC catheter ablation for the treatment of AVNRT in children and adolescents aged < 19 years with special focus on modulation versus ablation of the AV nodal slow pathway (SP)...

Xylanase is commonly added to pig diets rich in arabinoxylans to promote nutrient utilization and growth. However, high doses of xylanase could release high amounts of xylose in the upper gut, which could have negative nutritional and metabolic implications. However, the amount of xylose to elicit such adverse effects is not clear. Thus, two experiments were conducted to investigate the effects of dietary xylose on the growth performance and portal-drained viscera (PDV) fluxes of glucose (GLU), urea-N (BUN), insulin production, and O2 consumption in growing pigs...

Atrial electrical and structural remodeling is related to the perpetuation of atrial fibrillation (AF) subsequent to sinus node dysfunction. We investigated the relationship between AF recurrence after catheter ablation and sinus node dysfunction in long-standing persistent AF patients using the sinus node recovery time (SNRT) after defibrillation.Fifty-one consecutive patients who underwent a first ablation for long-standing persistent AF were enrolled. Intracardiac cardioversion was applied before ablation in the absence of any antiarrhythmic drugs, and the power required to defibrillate, number, and SNRT after defibrillation were measured...

Background: Observational studies have shown that dressings containing chlorhexidine gluconate (CHX) lower the incidence external ventricular drain (EVD) associated infections (EVDAI). This prospective, randomized controlled trial (RCT) studies the efficacy of CHX-containing dressings in reducing bacterial colonization, which represents an important risk factor for infectious complications. Methods: In this single-site, prospective, double-blinded RCT, patients aged ≥18 undergoing emergency EVD placement were randomly given either a CHX- or an otherwise identical control dressing at the skin exit wound of the EVD...

Aims: Permanent cardiac pacing of the His-bundle restores and retains normal electrical activation of the ventricles. Data on His-bundle pacing (HBP) are largely limited to small single-centre reports, and clinical benefits and risks have not been systematically examined. We sought to systematically examine published studies of patients undergoing permanent HBP and quantify the benefits and risks of the therapy. Methods and results: PubMed, Embase, and Cochrane Library were searched for full-text articles on permanent HBP...

Hematochezia is a rare clinical presentation of congenital extrahepatic portosystemic shunt (CEPS). We describe a series of three patients with type II CEPS presenting as hematochezia that were treated by catheter embolization, followed by a brief review of published articles. Hematochezia of the patients was due to the giant inferior mesenteric vein, superior rectal vein and colonic varices. The catheter embolization was successfully accomplished in all of the patients. After a mean follow-up of 27 months, no serious adverse effects were observed...

A position paper presents the standpoint of the Israeli Urological Association on clean intermittent catheterization (CIC) for all physicians and nurses. The position paper is based on international guidelines and professional literature and is adapted to medical activities in Israel. CIC is indicated for the treatment of temporary/permanent disability in the emptying of the bladder, which is expressed by large post-voided urine/urine retention and related complications. There are a few contra-indications for CIC (low bladder volume or compliance, pressure sores/external infection of the urethra, anatomical, functional or cognitive disorder that does not allow to perform CIC, recurrent macrohematuria or urethrorrhagia, urethral pain that does not allow frequent catheterization, patient unwillingness to perform CIC by himself or by another person)...

Male sling for urinary incontinence is usually accompanied by very good results, with a small number of complications,but, when appear, they may be redundant. Voluminous urethral stone developed on suburethral sling as a result of sling erosion into the proximal urethra is an extremely rare complication (following the analysis of cases published on the internet, the authors of this article no longer identified another similar case). We present the case of a patient who presented in our clinic for severe and permanent urinary incontinence, perineal discomfortand pain that was influenced by position...

INTRODUCTION: Ventricular arrhythmias are common in patients with advanced heart failure, which may also persist after sufficient intensive therapy for heart failure even with a left ventricular assist device. Although most ventricular arrhythmias have no hemodynamic relevance during left ventricular assist device support, some patients suffer from right ventricular decompensation due to ventricular arrhythmias resulting in severe hemodynamic deterioration and poor clinical outcomes. METHODS: We describe herein an left ventricular assist device patient with refractory ventricular arrhythmic storm early after left ventricular assist device implantation...

HD tissue hypoxia associates with organ dysfunctions. OER, the ratio between SaO2 and central-venous-oxygen-saturation, could estimate oxygen requirements during sessions, but no data are available. We evaluated OER behavior in 20 HD patients with permanent central venous catheter (CVC) as vascular access. Pre-HD OER (33.6 ± 1.4%; M ± SE) was higher than normal (range 20-30%). HD sessions increased OER to 39.2 ± 1.5% (M ± SE; p < 0.05) by 30' and to 47.4 ± 1.5% (M ± SE; p < 0...

OBJECTIVES: When drainage of an anomalous pulmonary vein is high into the superior vena cava (SVC), traditional techniques of 1-patch or 2-patch repair may be challenging. The cavoatrial anastomosis technique (the Warden procedure) was developed to reduce the risk of sinus node dysfunction and SVC obstruction. Herein, we describe the outcomes of the Warden procedure in children at a single institution. METHODS: A retrospective study was conducted on all children with partial anomalous pulmonary venous drainage (PAPVD) undergoing the Warden procedure from 1996 to 2015...

Enhanced parasympathetic tone may cause sinus bradycardia or pauses, transient or permanent atrioventricular block, with resultant vasovagal syncope. A substantial portion of these patients may be highly symptomatic and refractory to the conventional therapies and may require cardiac pacemaker implantation.

Background: The risk of spinal cord injury (SCI) due to decreased cord perfusion following thoracic/thoracoabdominal aneurysm surgery (T/TL-AAA) and thoracic endovascular aneurysm repair (TEVAR) ranges up to 20%. For decades, therefore, many vascular surgeons have utilized cerebrospinal fluid drainage (CSFD) to decrease intraspinal pressure and increase blood flow to the spinal cord, thus reducing the risk of SCI/ischemia. Methods: Multiple studies previously recommend utilizing CSFD following T/TL-AAA/TEVAR surgery to treat SCI by increasing spinal cord blood flow...
