INTRODUCTION: Catheter ablation of focal atrial tachycardia (FAT) can be a challenging procedure and results have been rarely described. The purpose of this study was to determine the characteristics and results of FAT ablation in the large cohort of the German Ablation Registry. METHODS: The German Ablation Registry is a nationwide prospective multicenter database including 12566 patients who underwent an ablation procedure between 2007 and 2010. Among them 431 (3...

A 52-year old female was admitted with complaints of palpitations for two years. The transthoracic echocardiography and electrocardiogram were both normal at the time of admission. We performed an electrophysiology study where the baseline intervals were in normal range. During burst atrial pacing we observed HV prolongation (HV = 80 ms) and infra-Hisian block.

BACKGROUND: The mechanisms by which persistent atrial fibrillation (AF) terminates via localized ablation are not well understood. To address the hypothesis that sites where localized ablation terminates persistent AF have characteristics identifiable with activation mapping during AF, we systematically examined activation patterns acquired only in cases of unequivocal termination by ablation. METHODS AND RESULTS: We recruited 57 patients with persistent AF undergoing ablation, in whom localized ablation terminated AF to sinus rhythm or organized tachycardia...

The atrioventricular node (AVN) is a complex structure that performs a variety of functions in the heart. The AVN is primarily an electrical gatekeeper between the atria and ventricles and introduces a delay between atrial and ventricular excitation, allowing for efficient ventricular filling. The AVN is composed of several compartments that safely transmit electrical excitation from the atria to the ventricles via the fast or slow pathways. There are many electrophysiological differences between these pathways, including conduction time and electrical refractoriness, that increase the predisposition of the atrioventricular junction to arrhythmias such as atrioventricular nodal re-entrant tachycardia...

Objective: To observe the clinical efficacy and safety of coil embolization of septal branch in the treatment of obstructive hypertrophic cardiomyopathy (HOCM). Methods: Eighteen patients with HOCM hospitalized in our department from September 2014 to October 2016 were enrolled in this study. There were 12 males and 6 females in this cohort and the age of patients ranged from 22 to 64 years old. Left ventricular outflow tract gradient (LVOTG) was derived from echocardiographic apical five-chamber view at pre-operation and at 48 hours and 6 months post operation...

We report a case of recurrent focal atrial tachycardia (AT) which mechanisms could be resolved by using non-invasive electrocardiographic imaging (ECGI) reconstructing epicardial potentials and rapid high-density endocardial contact mapping (Rhythmia™). ECGI demonstrated focal activity from the anterior of the left superior pulmonary vein antrum, although Rhythmia™ showed focal activity from the high anterior left atrium with the 2nd focus originating from the site where identical to the focus on the ECGI map with slightly delay (by 8 ms)...

INTRODUCTION: Recent studies suggest that atrial fibrillation (AF) is maintained by electrical activity arising from focal sources. We sought to test whether catheter ablation that targets focal sources can improve on current ablation protocols for persistent AF. METHODS AND RESULTS: In patients with persistent AF whose AF did not terminate with pulmonary vein isolation, the left atrium was mapped with a 20-pole high-density mapping catheter using CARTO®3 navigation...

Commonly reported complications of hepatic cysts are spontaneous hemorrhage, rupture into the peritoneal cavity, infection and compression of the biliary tree however cardiac complications are not commonly reported. We are presenting a case of a large liver cyst presenting with right atrial and ventricular inflow tract impingement resulting in cardiac symptoms. A 68 year-old Hispanic female presented with one month of fatigue and shortness of breath after household work and walking less than one block, right upper quadrant pain and weight loss...

BACKGROUND: Postoperative arrhythmias are a known complication after cardiac surgical repairs for congenital heart disease. METHODS: Data were reviewed pertaining to incidence, diagnosis, potential risk factors, and management of postoperative arrhythmias in 369 consecutive patients under 18 years of age, undergoing elective open heart surgery. All children were admitted to the intensive care unit and continuous electrocardiographic monitoring was performed. Patient factors such as Aristotle Basic Complexity Score, total surgical duration, hypotension, tachycardia, serum lactate level, and inotropic score were analyzed...

BACKGROUND: Ebstein anomaly is a complex, congenital heart defect that is associated with a variety of cardiac abnormalities. Studies found a similar sarcomere gene mutation in patients with Ebstein anomaly (EA) and patients with isolated left ventricular non-compaction (LVNC). AIM: We aimed to show the prevalence of LVNC and its potential relationship with severe cardiac events (VT - ventricular tachycardia, cardiac arrest) in adult patients with EA. METHODS: We conducted a retrospective search of our institutional database from 2010 to 2014 for patients with EA and reviewed patients' medical records (age, sex, clinical presentation, electrocardiographic, echocardiographic, and CMR - cardiac magnetic resonance features)...

AIM: To investigate the influence of increasing age on clinical presentation, treatment and long-term outcome in patients with inducible paroxysmal supraventricular tachycardia (SVT) without pre-excitation syndromes. METHODS: Clinical and electrophysiological study (EPS) data, as well as long-term clinical outcome (mean follow-up 2.4±4.0 years) were collected in patients referred for regular tachycardia with inducible SVT during EPS without pre-excitation. RESULTS: Among 1960 referred patients, 301 patients (15...

Background: Cardiac involvement is frequent in the course of human immunodeficiency virus (HIV) infection disease. This work aimed at studying the profile of echocardiographic and electrocardiography (ECG) abnormalities in adults living with HIV (PLHIV), compared to those not infected with HIV at the treatment unit of the Yaoundé Central Hospital. Methods: We carried out a case-control study over three months at the HIV treatment unit. We included adults of both sexes, aged ≥21 years, HIV-infected (cases), and age and sex matched controls...

Aims: Tachycardia mediated by septal accessory pathways (AP) and atypical atrioventricular nodal re-entry (AVNRT) require careful electrophysiologic evaluation for differential diagnosis. We aim to describe the differential behaviour of local ventriculo-atrial (VA) intervals which predicts the tachycardia mechanism. Methods and results: The local VA intervals at the para-Hisian septum were measured under three different situations: (i) tachycardia; (ii) sustained entrainment from the right ventricular apex (RVA); and (iii) continuous pacing from the RVA during sinus rhythm...

INTRODUCTION: Hybrid ablation, an emerging therapy that combines surgical intervention and catheter ablation, has become a viable option for the treatment of persistent atrial fibrillation. In this analysis, we aimed to evaluate the safety and efficacy of hybrid ablation, as well as compare the outcomes of one-step and staged approaches. METHODS: We conducted a search in major online databases and selected the studies that met the inclusion criteria. The primary endpoint was defined as no episode of atrial fibrillation or atrial tachycardia lasting longer than 30 seconds without administration of antiarrhythmic drugs...

Data about the safety of edoxaban in patients who underwent left atrial (LA) radiofrequency (RF) ablation procedures are lacking. This study sought to compare the safety of uninterrupted edoxaban with uninterrupted phenprocoumon administration during LA RF ablation for atrial fibrillation and atrial tachycardia. In total, 231 patients (mean age 64 ± 11years, male 71%) who underwent LA RF ablation under continuous oral anticoagulation (OAC) with edoxaban or phenprocoumon were included in the study. Patients on uninterrupted edoxaban (60 mg or 30 mg/day for at least 4 weeks) were matched for gender, age and type of arrhythmia with 2 patients on uninterrupted phenprocoumon (international normalized ratio 2 to 3)...
