Objective: To assess the incidence and predictors of heart rhythm and conduction disturbances in hypertensive obese patients with and without obstructive sleep apnea (OSA). Methods: This is an open, cohort, prospective study. Out of 493 screened patients, we selected 279 hypertensive, obese individuals without severe concomitant diseases: 75 patients without sleep-disordered breathing (non-SDB group), and 204 patients with OSA (OSA group). At baseline, all patients underwent examination, including ECG, Holter ECG monitoring, and sleep study...

One in five people with Down syndrome (DS) are born with an atrioventricular septal defect (AVSD), an incidence 2,000 times higher than in the euploid population. The genetic loci that contribute to this risk are poorly understood. In this study, we tested two hypotheses: 1) individuals with DS carrying chromosome 21 copy number variants (CNVs) that interrupt exons may be protected from AVSD, because these CNVs return AVSD susceptibility loci back to disomy, and 2) individuals with DS carrying chromosome 21 genes spanned by microduplications are at greater risk for AVSD because these microduplications boost the dosage of AVSD susceptibility loci beyond a tolerable threshold...

BACKGROUND: Steroid-eluting pacemaker leads suppress acute rises in pacing threshold by preventing inflammatory processes. However, we occasionally encounter not persistent but transient rise in the atrial capture threshold (TRACT) early after pacemaker implantation. We believe that this phenomenon is under-recognized in clinical practice and may potentially lead to unnecessary re-intervention. We aimed to clarify the prevalence, predictors, and possible mechanisms of TRACT. METHODS AND RESULTS: We reviewed clinical records from 239 consecutive patients who underwent dual-chamber pacemaker implantation for sick sinus syndrome (SSS) (N = 102) or atrioventricular block (AVB) (N = 137)...

Anti-atrial fibrillatory, proarrhythmic and cardiodepressive profiles of dronedarone were analyzed using the halothane-anesthetized beagle dogs (n = 4) to create a standard protocol for clarifying both efficacy and adverse effects of anti-atrial fibrillatory drugs. Intravenous administration of dronedarone hydrochloride in doses of 0.3 and 3 mg/kg over 30 s attained the peak plasma concentrations of 61 and 1248 ng/mL, respectively, reflecting sub- to supra-therapeutic ones. The low dose decreased the left ventricular contraction and mean blood pressure, which were enhanced at the high dose...

Background: Catheter ablation of atrioventricular nodal reentrant tachycardia (AVNRT) is a commonly performed electrophysiology (EP) procedure. Few data exist comparing conventional (CONV) versus novel ablation strategies from both clinical and direct cost perspectives. We sought to investigate the disposable costs and clinical outcomes associated with three different ablation methodologies used in the ablation of AVNRT. Methods: We performed a retrospective review of AVNRT ablations performed at Augusta University Medical Center from 2006 to 2014...

OBJECTIVES: We analyzed the mortality and morbidity of congenital heart surgery in Japan using the Japan Cardiovascular Surgery Database (JCVSD). METHODS: Data regarding congenital heart surgery performed between January 2013 and December 2014 were obtained from JCVSD. The 20 most frequent procedures were selected and the mortality rates and major morbidities were analyzed. RESULTS: The mortality rates of atrial septal defect repair and ventricular septal defect repair were less than 1%, and the mortality rates of tetralogy of Fallot repair, complete atrioventricular septal defect repair, bidirectional Glenn, and total cavopulmonary connection were less than 2%...

PURPOSE: Paroxysmal supraventricular tachycardia (PSVT) ablation can result in injury to the atrioventricular (AV) node causing complete heart block requiring permanent pacemaker (PPM) implantation. Few studies have examined the impact of hospital PSVT ablation volume and PPM implantation rates post ablation. METHODS: We included adult patients from the Nationwide Inpatient Sample (NIS) database, from 1998 to 2011, using ICD-9 diagnoses codes 427.0 and 427.89 for PSVT and ICD-9 procedure code 37...

In a man with a wide-QRS complex tachycardia, a history of an inferior left ventricular scar, atrioventricular dissociation during the tachycardia, and a QRS morphology inconsistent with right or left bundle branch block exclude a diagnosis of supraventricular tachycardia with aberrant ventricular conduction due to bundle branch block or ventricular preexcitation and establish a diagnosis of ventricular tachycardia.

We assessed the dynamics in the prevalence of children with congenital heart disease (CHD) and Down syndrome in Germany with regard to phenotype, severity, and gender. Data from patients with CHD and Down syndrome born between 1980 and 2014 were analyzed, who are registered with the German National Register for Congenital Heart Defects. One thousand six hundred eighteen CHD patients with Down syndrome were identified. The prevalence of children born with both Down syndrome and CHD was constant from 2005 to 2009 but increased from 2010 to 2014...

OBJECTIVE: PR interval (PR) is a heritable electrocardiographic measure of atrial and atrioventricular nodal conduction. Changes in PR duration may be associated with atrial fibrillation, heart failure and all-cause mortality. Hispanic/Latino populations have high burdens of cardiovascular morbidity and mortality, are highly admixed and represent exceptional opportunities for novel locus identification. However, they remain chronically understudied. We present the first genome-wide association study (GWAS) of PR in 14 756 participants of Hispanic/Latino ancestry from three studies...

BACKGROUND: Sutureless aortic valve prostheses have the potential to augment the adoption of alternative incision approaches for aortic valve replacement (AVR). Still, we lack the evidence on which surgical approach is best associated with sutureless AVR. METHODS: Data on 483 patients undergoing sutureless small incision AVR between 2010-2014 in two European institutions (207 with partial sternotomy (MS) and 276 via right anterior minithoracotomy (RAMT)) have been retrospectively analyzed...

Neonatal lupus erythematosus is an uncommon syndrome, which is caused by transplacental passage of maternal autoantibodies to Sjögren's syndrome A or B autoantigens. The clinical presentation includes distinctive cutaneous lesions resembling those seen in systemic lupus erythematosus, hepatobiliary disease, and cytopenias, which disappear with the clearance of maternal autoantibodies. The most severe presentation is a total atrioventricular heart block, which begins during the second trimester of gestation and is irreversible...

A 04-year-old boy was referred to our institution with severe, progressive heart failure of 4-months duration associated with a persistent wide QRS tachycardia with left bundle branch block and severe left ventricular dysfunction. Because of incessant wide QRS tachycardia refractory to antiarrhythmic drugs, he was referred for electrophysiological study. The ECG was suggestive of VT arising from the right ventricle near the His area. Electrophysiological study revealed that origin of tachycardia was septum of the right ventricle, near His bundle, however the procedure was not successful and an inadvertent complete atrioventricular conduction block occurred...

Fetal hydrops is a serious complication of immune-mediated congenital complete atrioventricular block. We present the case of a fetus with severe hydrops and profound bradycardia and an unusual favourable outcome. This case enhances the importance of considering the contribution of ventricular ectopic beats to the cardiac output when counselling and predicting outcome of complete heart block.

Aims: Left ventricular (LV) fusion pacing appears to be at least as beneficial as biventricular pacing in cardiac resynchronization therapy (CRT). Optimal LV fusion pacing critically requires adjusting the atrioventricular (AV)-delay to the delay between atrial pacing and intrinsic right ventricular (RV) activation (Ap-RV). We explored the use of electrogram (EGM)-based vectorloop (EGMV) derived from EGMs of implanted pacing leads to achieve optimal LV fusion pacing and to compare it with conventional approaches...

A 71-year-old woman with narrow QRS tachycardia was referred for catheter ablation. The clinical tachycardia was diagnosed as slow/fast form of atrioventricular (AV) nodal reentrant tachycardia (AVNRT) with the upper common pathway. Although neither conventional nor double atrial programmed extrastimulation (APS) showed any evidence of a dual AV nodal pathway, AV simultaneous pacing during basic stimulation preceding APS (AVSP-APS) reproducibly revealed a dual AV nodal pathway as a double ventricular response...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is the preferred alternative to traditional surgical aortic valve replacement; however, it remains expensive. One potential driver of cost is the need for postprocedural monitoring for conduction abnormalities after TAVI. Given the paucity of literature on the optimal length of monitoring, we aimed to determine when clinically significant conduction abnormalities leading to permanent pacemaker (PPM) insertion after TAVI were first identified...
