INTRODUCTION: Effects of cardiac resynchronization therapy (CRT) on arrhythmogenicity and sudden death have not been fully ascertained. CRT has been shown to increase transmural dispersion of repolarization (TDR) immediately on implantation, that may favorably remodel on long-term follow-up. However, such a hypothesis has not been prospectively evaluated. METHODS AND RESULTS: We included 35 consecutive patients who underwent CRT implantation between September 2013 & August 2014 (mean age 56...

INTRODUCTION: Visualization of left atrial (LA) anatomy using image integration modules has been associated with decreased radiation exposure and improved procedural outcome when used for guidance of pulmonary vein isolation (PVI) in atrial fibrillation (AF) ablation. We evaluated the CARTOSEG™ CT Segmentation Module (Biosense Webster, Inc.) that offers a new CT-specific semi-automatic reconstruction of the atrial endocardium. METHODS: The CARTOSEG™ CT Segmentation Module software was assessed prospectively in 80 patients undergoing AF ablation...

BACKGROUND: The daily activity of pediatric patients with implantable cardiac devices provides behavioral evidence of functional outcomes. Modern devices provide continuous accelerometer data that is sensitive to movement, but normative values have not been published for pediatric activity rates. This study provides the first normative accelerometer data on activity rates in a large sample of pediatric cardiac device patients. METHODS: Patients were between 3 and 18 years old, (N = 1,905) and implanted with a cardiac device from a single device company, and enrolled in remote monitoring...

BACKGROUND: Fluoroless transseptal (TS) puncture may represent the final step towards elimination of fluoroscopy in pediatric supraventricular tachycardia ablation in normal hearts. We aimed to demonstrate the safety and feasibility of fluoroless TS puncture in pediatric patients and compare procedural timing with the fluoroscopic approach. METHODS: We performed a retrospective cohort analysis of all TS procedures performed without fluoroscopy at our institution; fluoroless TS procedures were performed under intracardiac echocardiography (ICE) guidance after creation of 3D electroanatomic map and identification of fossa ovalis on 3D map...

Vasovagal syncope (VVS) or neurocardiogenic syncope is defined by transient loss of consciousness with spontaneous and rapid recovery. Recently, a closed loop stimulation pacing system (CLS) has emerged as a new strategy which appears superior to conventional pacing for patients with refractory syncope. However, it's efficacy remains of considerable debate and large randomized controlled clinical trials are needed. Between 2002 and 2017, 12 total studies evaluated the use of CLS pacing in patients with refractory VVS, and are summarized in this article...

BACKGROUND: Anatomically guided pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. However, the position where to confirm electrical isolation is ill-defined. The aim of the current study was to quantify the relationship between the anatomical and electrical definition of the pulmonary vein ostium. METHODS: We analyzed 20 patients with paroxysmal AF undergoing PVI using radiofrequency energy and an electroanatomical mapping system...

BACKGROUND: Electrocardiogram abnormalities have been reported during electroconvulsive therapy (ECT). A corrected QT interval (QTc) prolongation indicates delayed ventricular repolarization, which can trigger ventricular arrhythmias such as torsade de pointes (TdP). We examined the QTc changes during generalized tonic-clonic seizures induced by ECT, and the effects of atropine sulfate on these QTc changes. METHODS: We analyzed heart rate, QT interval, and QTc in 32 patients with depression who underwent ECT (25 women, 67...

BACKGROUND: Catheter ablation of right sided accessory pathways (AP) has lower success and higher recurrence rates compared to left-sided substrates. Irrigated-tip catheter (ITC) ablation might offer an advantage in this setting but data about its use in patients below 18 years is scarce. Aim of this study was to compare an ITC approach to conventional catheter ablation. METHODS: A retrospective analysis of all patients < 18 years undergoing radiofrequency ablation (RFA) for right-sided APs from 2004 to 2014 at our institution was performed...

BACKGROUND: Iodine-123 metaiodobenzylguanidine ((123) I-MIBG) is useful for detecting sympathetic innervation in the heart, and has been closely associated with fatal arrhythmias. However, such imaging is typically calibrated to the area of highest uptake and thus is unable to identify areas of hyperinnervation. We hypothesized that normal (123) I-MIBG uptake regions in the denervated heart would demonstrate nerve sprouting and correlate with the potential for arrhythmogenesis. METHODS: Twenty New Zealand white rabbits treated with phenol or sham were prepared under anesthesia...

BACKGROUND: A proportion of patients with an ICD in prevention of sudden cardiac death will only receive their first appropriate ICD therapy (AT) after device replacement. Clinical reassessment at the time of replacement could be helpful to guide the decision to replace or not in the future. METHODS: All patients with an ICD for primary or secondary prevention in ischemic (ICM) or non-ischemic cardiomyopathy were included in a single-center retrospective registry...

Ventricular tachycardia (VT) commonly occurs in patients with ischemic or non-ischemic cardiomyopathy and requires anti-arrhythmic drugs, ablation or advanced circulatory support. However, life-threatening VT may be refractory to these therapies, and may cause frequent implantable cardioverter defibrillator (ICD) discharges. Left cardiac sympathetic denervation reduces the occurrence of these fatal arrhythmias by inhibiting the sympathetic outflow to the cardiac tissue. We present a 69-year-old man with non-ischemic cardiomyopathy, life-threatening VT, and hemodynamic instability with numerous ICD discharges who remained refractory to antiarrhythmic drug therapy and ablation attempts...

BACKGROUND: The autonomic nervous system (ANS) is a potentially potent modulator of the initiation and perpetuation of atrial fibrillation(AF),whereas the presence of AF can activate and alter the ANS.The catheter ablation of AF(AFCA) may cause the cardiac ANS dysfunction, whereas restoration of sinus rhythm or sympathovagal imbalance by AFCA can reverse this process. Our principal goal was to investigate the short-term effect of AFCA on ANS functions evaluated by noninvasive chronotropic (CI), resting heart rate (RHR) and heart rate recovery (HRR) indices...

BACKGROUND: Cardiovascular implantable electronic devices (CIEDs) can be life-saving. However, complications from CIED infection can be life-threatening often requiring device removal. Despite publication of CIED infection management guidelines there remains marked variation in clinical practice. OBJECTIVE: To better understand and quantify these differences, we conducted a multi-national survey of practitioners of CIED management. METHODS: An electronic survey was sent to Heart Rhythm Society members, spanning 70 countries across six continents...
