Aims: Oesophagogastroduodenoscopy (OGD) after catheter ablation (CA) of atrial fibrillation (AF) revealed a high rate of procedure related oesophageal lesions. We hypothesized that magnetically guided CA with careful radiofrequency energy titration at the posterior left atrial (LA) wall limits the incidence of oesophageal tissue damage. Methods and results: As a part of the prospective "Remote MAGNetic catheter Ablation for Atrial Fibrillation" (MAGNA-AF) registry, 251 out of 266 consecutive patients underwent OGD after magnetically guided single-CA for AF...

BACKGROUND: Expandable, rapid deployment aortic valves may interfere with the cardiac conduction system, which can lead to permanent pacemaker implantation (PPI). We sought to characterize PPI following rapid deployment aortic valve replacement (RDAVR) with the EDWARDS INTUITY valve system and investigate associated factors. METHODS: We analyzed 708 patients from 29 centers in the TRANSFORM trial undergoing RDAVR ± CABG without pre-existing pacemakers. Intrinsic conduction status was recorded as well as PPI incidence through one year...

A 74-year-old female underwent an uneventful bilateral thoracoscopic maze procedure for persistent atrial fibrillation with continuous transesophageal echocardiographic (TEE) guidance. She presented six weeks later with persistent fever and focal neurological signs. Computed tomography of the thorax revealed air in the posterior LA, raising suspicion for an abscess versus an atrioesophageal fistula (AEF). Before undergoing an exploratory median sternotomy, an esophagogastroduodenoscopy (EGD) was performed by the surgeon to check for any esophageal pathology...

We assessed the feasibility of achieving acute, sustained blood pressure reductions through the use of cardiac pacing algorithms delivered via standard dual-chamber pacing based on introducing short atrio-ventricular (AV) delays (SAVD). Eighteen hypertensive subjects (57.3 ± 9.8 years old; 10 male and 8 female) with average initial systolic and diastolic blood pressures of 151.2 ± 17.6/92.2 ± 12.7 mmHg already scheduled to undergo an invasive electrophysiology procedure were included in this study. Pacing sequences were applied for ∼1-minute intervals with AV delays of 80, 40, 20 and 2 ms, while making high fidelity blood pressure measurements...

INTRODUCTION: Atrio-esophageal fistula (AEF) is a dire complication of atrial fibrillation ablation. The diagnostic yield of computed tomography (CT) chest, the role and timing of repeat testing, and the value of other investigations in the diagnosis of AEF is uncertain. METHODS: We systematically reviewed published AEF cases to evaluate radiological, bedside and biochemical investigations for AEF (registered on PROSPERO [CRD42017077493]). RESULTS: Eighty-seven articles with 126 patients (median age, 59 years; male, 71%) were included in the analysis...

The cardiac conduction system is a network of distinct cell types necessary for the coordinated contraction of the cardiac chambers. The distal portion, known as the ventricular conduction system, allows for the rapid transmission of impulses from the atrio-ventricular node to the ventricular myocardium and plays a central role in cardiac function as well as disease when perturbed. Notably, its patterning during embryogenesis is intimately linked to that of ventricular wall formation, including trabeculation and compaction...

Cardiac resynchronization therapy (CRT) is an important therapeutic tool in the management of patients with heart failure and electrical dyssynchrony. In appropriately selected patients, landmark randomized controlled trials have demonstrated morbidity and mortality benefit beyond standard goal-directed medical therapy. Current guidelines emphasize the greatest clinical efficacy of CRT in patients with symptomatic heart failure, left bundle branch block, and wide QRS duration (> 150 ms). Other relevant considerations include the presence of atrial fibrillation, the presence of AV block, the etiology of cardiomyopathy, the presence of masked left-sided conduction delay, and the impact of comorbidities that might predict poor clinical response...

BACKGROUND: Permanent pacemaker implantation (PPMI) after transcatheter aortic valve implantation (TAVI) remains an issue open for criticism. Aim of this study is to investigate a strategy to reduce PPMI rate after TAVI in general and more specifically after implantation of the LOTUS® prosthesis. METHODS: Through our learning curve, we have developed a structured protocol to reduce PPMI rate. The protocol includes: shallow implantation depth within the native annulus, strict adherence to the international guidelines for PPMI, PPMI not earlier than 5 days after TAVI, and intravenous chronotropic and steroidal treatment (orciprenaline 0...

Left atrial appendage closure was originally described by Madden in 1949 who was the first to perform appendix amputation. This was a very invasive procedure with poor outcome, but preformed for stroke prevention. Much later, it was James Cox whom described the Cox-Maze procedure, which included multiple incisions to create a maze like pathway for the electrical impulse to go undisturbed from the sinus node down to the atrio-ventricular node. Since then cardiac surgeons stopped focusing on the left atrial appendage and went on about seemingly more important things...

Heart failure patients are predisposed to develop arrhythmias. Supraventricular arrhythmias can exacerbate the heart failure symptoms by decreasing the effective cardiac output and their control require pharmacological, electrical, or catheter-based intervention. In the setting of atrial flutter or atrial fibrillation, anticoagulation becomes paramount to prevent systemic or cerebral embolism. Patients with heart failure are also prone to develop ventricular arrhythmias that can present a challenge to the managing clinician...

Peripheral chemoreflex mediated increases in both parasympathetic and sympathetic drive under chronic hypoxia may evoke bradyarrhythmias during apneic periods. We determined whether 1) voluntary apnea unmasks arrhythmia at low (344 m) and high (5,050 m) altitude, 2) high-altitude natives (Nepalese Sherpa) exhibit similar cardiovagal responses at altitude, and 3) bradyarrhythmias at altitude are partially chemoreflex mediated. Participants were grouped as Lowlanders ( n = 14; age = 27 ± 6 yr) and Nepalese Sherpa ( n = 8; age = 32 ± 11 yr)...

AIM: Functional analysis and measurement of left atrium are an integral part of cardiac evaluation, and they represent a key element during non-invasive analysis of diastolic function in patients with hypertension (HT) and/or heart failure with preserved ejection fraction (HFpEF). However, diastolic dysfunction remains quite elusive regarding classification, and atrial size and function are two key factors for left ventricular (LV) filling evaluation. Chronic left atrial (LA) remodelling is the final step of chronic intra-cavitary pressure overload, and it accompanies increased neurohormonal, proarrhythmic and prothrombotic activities...
