BACKGROUND: The concomitant presence of mitral stenosis (MS) in the setting of symptomatic aortic stenosis represent a clinical challenge. Little is known regarding the outcome of mitral stenosis (MS) patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Therefore, we sought to study the outcome of MS patients undergoing aortic valve replacement (AVR). METHOD: Using weighted data from the National Inpatient Sample (NIS) database between 2011 and 2014, we identified patients who were diagnosed with MS...

Background: Ventricular septal defect is a common congenital heart defect. Transcatheter closure of perimembranous ventricular septal defect (pmVSD) is an effective method alternative to surgical closure. The aim of the study is to evaluate the procedural result, early and long-term follow-up outcome of transcatheter closure of pmVSD. Methods: From January 2005 to December 2016, we retrospectively identified the patients who underwent transcatheter device closure of pmVSD. All patients underwent transthoracic echocardiography (TTE) and electrocardiogram (ECG) before and after the procedure...

Clinical trials and studies with ivabradine implicate cardiac pacemaker channels (HCN4) in the pathogenesis of atrial arrhythmias. Because acute changes in cardiac autonomic tone predispose to atrial arrhythmias, we studied humans in whom profound cardiac sympathetic activation was rapidly relieved to test influences of HCN4 inhibition with ivabradine on atrial arrhythmias. We tested 19 healthy participants with ivabradine, metoprolol, or placebo in a double blind, randomized, cross-over fashion on top of selective norepinephrine reuptake inhibition with reboxetine...

Although medical students are rarely instructed in traffic medicine in Germany, they are obliged to inform their patients about their fitness to drive after having become a medical doctor. This article gives an overview on the fitness to drive for patients with syncope by referring to the driving license regulation and the current guidelines released by the department of traffic. The driving license regulation distinguishes between group 1 and group 2 drivers. Group 1 drivers drive vehicles with a total weight less than 3...

Symptomatic bradycardia due to gastric distension is a rarely reported entity in the field of medicine. The mechanism of gastrointestinal distention that contributes to bradycardia is complex. A 75-year-old female with recurrent episodes of dizziness in the setting of gastric distension was found to have severe sinus bradycardia which resolved upon resolution of gastric distension. No structural or functional abnormality of heart was found. The patient was treated with permanent pacemaker implantation due to recurrent episodes of dizziness in the setting of sinus bradycardia...

BACKGROUND: The Asymptomatic Atrial Fibrillation and Stroke Evaluation in Pacemaker Patients and the Atrial Fibrillation Reduction Atrial Pacing Trial (ASSERT) demonstrated that subclinical atrial fibrillation (SCAF) was associated with a 2.5-fold increased risk of stroke. However, the absolute stroke rate was only 1.7% per year and fewer than 20% patients with stroke had SCAF in the preceding 30 days. This raises the possibility that SCAF is merely a risk marker for stroke rather than the cause...

The subcutaneous implantable cardioverter-defibrillator (S-ICD®, Boston Scientific, Marlborough, MA, USA, previously Cameron Health, San Clemente, CA, USA) represents an important milestone in ICD therapy for prevention of sudden cardiac death (SCD). Since the introduction of the S‑ICD in 2010, the device has undergone further development. Based on the unique feature of an entirely extracardiac implantation, the S‑ICD is able to reduce the common perioperative and long-term complications of the usual endovascular implanted ICD systems...

OBJECTIVES: The purpose of this study was to investigate the relationship between the onset of asystole and transient loss of consciousness (TLOC) in tilt-induced reflex syncope and estimate how often asystole was the principal cause of TLOC. BACKGROUND: The presence of asystole in vasovagal syncope (VVS) may prompt physicians to consider pacemaker therapy for syncope prevention, but the benefit of pacing is limited in VVS. METHODS: We evaluated electrocardiography, electroencephalography, blood pressure, and clinical findings during tilt-table tests...

OBJECTIVES: The primary objective was to assess the acute and 3-month performance of the modular antitachycardia pacing (ATP)-enabled leadless pacemaker (LP) and subcutaneous implantable cardioverter-defibrillator (S-ICD) system, particularly device-device communication and ATP delivery. BACKGROUND: Transvenous pacemakers and implantable cardioverter-defibrillators (ICDs) have considerable rates of lead complications. We examined the next step in multicomponent leadless cardiac rhythm management: feasibility of pacing (including ATP) by a LP, commanded by an implanted S-ICD through wireless, intrabody, device-device communication...

OBJECTIVES: The purpose of this study was to use direct cardiac resynchronization therapy (CRT)-paced contractility (dP/dt-max) response as a pre-implantation evaluation among patients with congenital heart disease (CHD) and follow clinical parameters and contractility indexes after CRT implantation. BACKGROUND: Patients with CHD often develop early heart failure with few therapeutic options, leading to heart transplantation (HT). Unfortunately, guidelines for CRT do not apply, and function evaluations by cardiac ultrasound are often inaccurate among CHD anatomies...
