Radiofrequency ablation of ventricular premature contraction originating from a native coronary cusp after transcatheter aortic valve replacement
We describe a case of radiofrequency ablation of ventricular premature contraction (VPC) originating from the left ventricular outflow tract after transcatheter aortic valve replacement. The VPC origin was the native aortic valve annulus between the left and right coronary cusps. Radiofrequency ablation was successfully performed by manipulating the ablation catheter from the gap between the sinotubular junction and implanted valve. (Source: Journal of Arrhythmia)

Value of adenosine test to reveal dormant conduction or adenosine-induced atrial fibrillation after pulmonary vein isolation
Conclusions Adenosine test after PVI to confirm the absence of dormant conduction and triggers initiating AF is beneficial to improve the outcomes after catheter ablation of PAF. (Source: Journal of Arrhythmia)

Loss of cardiac resynchronization therapy in a patient with a biventricular implantable cardioverter-defibrillator
Publication date: Available online 30 September 2017 Source:Journal of Arrhythmia Author(s): Mohammad Alasti, Karthikeyan Rangasamy, Stewart Healy, David Adam, Emily Kotschet Here, we discuss the case of a man with a history of ischemic cardiomyopathy and cardiac resynchronization therapy defibrillator implantation, who presented to emergency department with decompensated heart failure due to the loss of resynchronization therapy. The reason for the malfunction was left ventricle upper rate interval lock-in due to inappropriate programming of the device. (Source: Journal of Arrhythmia)

Cardiac troponin T as a predictor of cardiac death in patients with left ventricular dysfunction
Conclusion The cTnT levels in a stable state were associated with cardiac death in patients with LV dysfunction, even in those with non-ischemic diseases. (Source: Journal of Arrhythmia)

Syncope and the risk of sudden cardiac death: Evaluation, management, and prevention
Publication date: Available online 1 September 2017 Source:Journal of Arrhythmia Author(s): Ryan J. Koene, Wayne O. Adkisson, David G. Benditt Syncope is a clinical syndrome defined as a relatively brief self-limited transient loss of consciousness (TLOC) caused by a period of inadequate cerebral nutrient flow. Most often the trigger is an abrupt drop of systemic blood pressure. True syncope must be distinguished from other common non-syncope conditions in which real or apparent TLOC may occur such as seizures, concussions, or accidental falls. The causes of syncope are diverse, but in most instances, are relatively b...

Atriofascicular Mahaim with Ebstein anomaly: A case report
We report a case of a 7-year-old girl with atriofascicular Mahaim (AFM) pathway concomitant with Ebstein's anomaly. The QRS wave showed left bundle branch block pattern on electrocardiogram. Holter electrocardiogram showed prolongation of the PR interval and QRS morphological change during sinus tachycardia. An electrophysiological study demonstrated that the distal His potential appeared earlier than the proximal His potential, which suggested retrograde His conduction toward the atrioventricular node. Conduction from the Mahaim fiber to the His bundle was faster than that from the atrioventricular node towards the His bu...

CHADS2 and modified CHA2DS2-VASc scores for the prediction of congestive heart failure in patients with nonvalvular atrial fibrillation
Conclusion Calculation of the CHADS2 and mCHA2DS2-VASc scores in order to evaluate the risk of systemic thromboembolism was useful to predict the onset of CHF, but not all-cause death, in patients with NVAF. (Source: Journal of Arrhythmia)

Three cases of vasospastic angina following catheter ablation of atrial fibrillation
Publication date: Available online 31 July 2017 Source:Journal of Arrhythmia Author(s): Yoshihiko Kagawa, Eitaro Fujii, Satoshi Fujita, Norikazu Yamada, Masaaki Ito Pulmonary vein isolation is an effective treatment for patients with atrial fibrillation (AF).Although vasospastic angina (VSA) is not a common complication after ablation of AF, we report 3 cases of VSA following ablation of persistent AF. Two of the 3 patients felt chest pain following pulmonary vein isolation, and complex fractionated atrial electrogram ablations were performed. ST elevation in the inferior leads and atrioventricular block occurred be...

The influence of residual apixaban on bleeding complications during and after catheter ablation of atrial fibrillation
Conclusions Low residual plasma apixaban is associated with a higher incidence of bleeding complications during/after AF ablation, potentially because of a greater heparin requirement during AF ablation. (Source: Journal of Arrhythmia)

Sudden failure of ventricular pacing and recovery in a patient with cardiac sarcoidosis

Minimally invasive, pericardial implantable cardioverter-defibrillator placement in a young child
We report the successful minimally invasive placement of a pericardial implantable cardioverter-defibrillator (ICD) in a 16-kg child. A transvenous ICD dual coil was advanced through a small subxiphoid incision and screwed into the oblique sinus pericardium under fluoroscopic guidance. An additional sense-pace lead was sutured onto the right ventricular apex, and the generator was placed in the upper abdominal wall through the same incision. Threshold testing demonstrated successful defibrillation at 15J. After implantation, the patient had two episodes of appropriate shock for ventricular fibrillation. The ICD system cont...
