An implantable cardioverter defibrillator (ICD) storm involves very frequent arrhythmia episodes and ICD shocks, and it is associated with poor short-term and long-term prognosis. Radiofrequency catheter ablation (RFCA) can be used as an effective rescue treatment for patients with an ICD storm. To our knowledge, this is the first report of an infant with HCM presenting with an ICD storm and undergoing successful radiofrequency catheter ablation salvage treatment for the fast left posterior fascicular VT.

BACKGROUND: Experience with percutaneous epicardial ablation of tachyarrhythmia in pediatrics is limited. This case series addresses the feasibility, safety and complications of the procedure in children. METHODS: A total of 9 patients underwent 10 epicardial ablation procedures from 2002 to 2013 at two academic centers. Activation mapping was performed in all cases, and electro-anatomic map was utilized in 9 of the 10 procedures. Patients had undergone 1-3 failed endocardial catheter ablations in addition to medical management, and all had symptoms, a high-risk accessory pathway (AP), aborted cardiac arrest with Wolff-Parkinson-White syndrome (WPW) or ventricular dysfunction...

BACKGROUND: Catheter ablation (CA) has an established role in scar-related ventricular tachycardia (VT), but the risk of recurrences is substantial and the appropriate intensity of post-ablation monitoring unknown. The implication of timing of post-ablation VT recurrence has not been adequately investigated. METHODS: We studied 120 consecutive patients with scar-related VT (age 60±15 years, LVEF 39±16%, 52% ischemic etiology) with at least 2-years of follow-up...

AIMS: Right ventricular apical pacing (RVA) can induce left ventricular (LV) dyssynchrony, remodelling and dysfunction in children with complete atrioventricular block (CAVB). We compared the functional outcome of RVA with RV alternative pacing sites (RVAPS), including parahisian, septal, and outflow tract sites. METHODS: This is a single-centre, retrospective study. Data were collected before pacemaker implantation (transvenous leads), postoperatively, at 6 months and at 1-2-3-4 years...

BACKGROUND: Dual RV has been proposed as an alternative for patients with heart failure undergoing cardiac resynchronization therapy (CRT) with a failure to deliver a coronary sinus (CS) lead. Only short-term haemodynamic and echocardiographic results of Dual RV are available. We aimed to assess the long-term results of Dual-site right ventricular pacing (Dual RV) and its impact on survival. METHODS: Multicentre retrospective assessment of all CRT implants during a 12-year period...

BACKGROUND: The design of pacemaker leads has continued to evolve; ease of lead handling, improved electrical performance and MRI conditional aspects have become more important, while safety remains critical. The INGEVITY™ family leads was designed to provide MRI conditional aspects, decreased diameter, and improved performance of pacemaker leads. The INGEVITY study is an investigational device exemption trial evaluating the acute and chronic safety and effectiveness of these leads...

BACKGROUND: A significant number of ventricular tachycardia circuits are located close to the epicardial surface and are amendable to epicardial ablation. Epicardial fat often interferes with substrate mapping and ablation, though little is known regarding the distribution of fat and its fluctuation with the cardiac cycle. METHODS: We studied 40 patients who underwent a 64-slice MDCT in order to describe patterns of epicardial fat distribution, variation during cardiac cycle and clinical predictors of epicardial fat...

OBJECTIVES: We assessed the effectiveness and safety of cryoballoon ablation (CBA) in the Chinese population with paroxysmal atrial fibrillation (AF) with a 1-year follow-up and determined the association of early recurrence of atrial tachyarrhythmias (ERAT) with late recurrence (LR). METHODS: A total of 114 patients (age 61±10 years, 78 males) with paroxysmal AF who underwent CBA were consecutively enrolled. After procedures, patients were observed for 3 d with continuous ECG monitoring in the hospital with routine follow-up visits at 3-month, 6-month, and 1-year...

INTRODUCTION: Implantable loop recorder (ILR) insertion has historically been performed in a surgical environment such as the electrophysiology (EP) lab. The newest generation loop recorder (Medtronic Reveal LINQ™) is injectable with potential for implantation in a non-EP lab setting by advanced practice providers (APPs) facilitating improved workflow and resource utilization. We report the safety and efficacy of injectable ILR placement in the ambulatory care setting by APPs. METHODS: A retrospective review was performed including all patients referred for injectable ILR placement from March 2014 to November 2015...

BACKGROUND: 20-30% of patients do not benefit from CRT when the established selection criteria were applied. We hypothesized that a combined assessment of mechanical dyssynchrony, myocardial deformation and diastolic function would identify patients who would benefit most from CRT. METHOD: In 36 CRT patients, clinical evaluation and echocardiography were performed before and after CRT. Patients were classified into 3 subgroups according to their amount of response: echocardiographic responders, clinical responders, and nonresponders...

BACKGROUND: Inflammation has been evidenced as a critical contributable mechanism for the atrial fibrillation (AF) onset and development. As the consistent inflammatory and oxidative marker, the effects of white blood cell (WBC) and its differential on lone atrial fibrillation (LAF) were investigated in the study. METHODS: A total of 126 patients with paroxysmal LAF who scheduled for rhythm control drug therapy and 120 age- and gender-matched subjects in sinus rhythm were included sequentially...
