Bidirectional ventricular tachycardia in cardiac sarcoidosis
Publication date: Available online 4 June 2016 Source:Journal of Arrhythmia Author(s): Mina M. Benjamin, Kevin Hayes, Michael E. Field, Melvin M. Scheinman, Kurt S. Hoffmayer A 73-year-old man with history of pulmonary sarcoidosis was found to have runs of non-sustained bidirectional ventricular tachycardia (BVT) with two different QRS morphologies on a Holter monitor. Cardiac magnetic resonance delayed gadolinium imaging revealed a region of patchy mid-myocardial enhancement within the left ventricular basal inferolateral myocardium. An 18-fluorodeoxyglucose positron emission tomography (FDG-PET) showed incr...

Immediate discontinuation of ablation during pulmonary vein isolation remarkably decreases the incidence of esophageal thermal lesions even when using steerable sheaths
Conclusions Immediate discontinuation of ablation during pulmonary vein isolation remarkably decreased the incidence of EsoTLs, even when using STS. (Source: Journal of Arrhythmia)

Successful percutaneous epicardial catheter ablation of ventricular tachycardia arising from the crux of the heart in a patient with prior coronary artery bypass grafting
This report suggested that epicardial VT arising from the crux of the heart could be successfully treated by catheter ablation via subxiphoidal pericardial approach despite pericardial adhesions complicated by prior CABG. (Source: Journal of Arrhythmia)

Detection of sequential activation of left atrium and coronary sinus musculature in the general population
Conclusions Far-field LA potentials are often recorded in the CS during sequential LA and CSM activation in the general population. The timing of LA potentials in CS recordings reflected the direction of conduction across the CSM. (Source: Journal of Arrhythmia)

Non-vitamin K antagonist oral anticoagulants versus warfarin for cardioversion of atrial fibrillation in clinical practice: A single-center experience
Conclusion NOACs may be used as an alternative to VKAs for ECV and may allow prompt ECV in clinical practices. (Source: Journal of Arrhythmia)

Successful intermuscular implantation of subcutaneous implantable cardioverter defibrillator in a Japanese patient with pectus excavatum
Publication date: Available online 1 June 2016 Source:Journal of Arrhythmia Author(s): Yusuke Kondo, Marehiko Ueda, Joachim Winter, Miyo Nakano, Masahiro Nakano, Masayuki Ishimura, Kazuo Miyazawa, Kaoru Tateno, Yoshio Kobayashi The entirely subcutaneous implantable cardioverter-defibrillator (ICD) system was developed to provide a life-saving defibrillation therapy that does not affect the heart and vasculature. The subcutaneous ICD is preferred over the transvenous ICD for patients with a history of recurrent infection presenting major life-threatening rhythms. In this case report, we describe the fi...

Assessment of drug-induced proarrhythmias due to pilsicainide in patients with atrial tachyarrhythmias
Conclusions DIPs caused by pilsicainide administration were strongly associated with renal dysfunction. Hence, confirmation of renal function would be necessary prior to and/or during the pilsicainide administration. (Source: Journal of Arrhythmia)

Risk factors for amiodarone-induced thyroid dysfunction in Japan
Conclusion DCM and cardiac sarcoidosis were identified as risk factors for amiodarone-induced hyperthyroidism. Risk factors for amiodarone-induced hypothyroidism included higher baseline TSH level and lower baseline free T4 level, suggesting that subclinical hypothyroidism may be a potential risk factor for the development of amiodarone-induced hypothyroidism.

Trends and determinant factors in the use of cardiac resynchronization therapy devices in Japan: Analysis of the Japan cardiac device treatment registry database
Conclusions Younger age, male sex, reduced LVEF, and a history of NSVT were independently associated with the choice of CRT-D for primary prevention of sudden cardiac death in patients with heart failure in Japan. (Source: Journal of Arrhythmia)

The association between defibrillation shock energy and acute cardiac damage in patients with implantable cardioverter defibrillators
Conclusions Elevated levels of myocardial damage markers such as c-TNT and H-FABP were not found after ≤10J-DT. In addition, an acceptable success rate was confirmed in ≤10J-DT. (Source: Journal of Arrhythmia)

Catheter ablation of anteroseptal accessory pathways from the aortic cusps: A case series and a review of the literature
We describe two cases of true para-Hisian accessory pathways successfully ablated from the aortic cusps (right coronary cusp and non-coronary cusp, respectively) along with a review of the current literature. Due to the close proximity to the atrioventricular node and the high risk of complication, mapping of the aortic cusps should always be considered in the case of anteroseptal accessory pathways. Anteroseptal accessory pathways can be safely and effectively ablated from the aortic cusps with good long-term outcomes. (Source: Journal of Arrhythmia)

Impact of catheter ablation of ventricular tachycardia in patients with prior myocardial infarctions
Conclusions The catheter ablation targeting the isthmus of prior-MIVT and non-inducibility at the end of the procedure can provide a satisfactory follow-up result. (Source: Journal of Arrhythmia)
