CONGRESS ABSTRACT

BACKGROUND Despite sudden cardiac death (SCD) is a rare phenomenon in pediatric age, the use of the implantable defibrillator (ICD) is progressively increasing in consideration of its life-saving role both in primary and in secondary prevention. The aim of this study is to assess the long-term follow-up of pediatric…

A 43-year-old man was referred to our center for complete exposure of ICD pocket. The generator was fully exposed in the right prepectoral–axillary region, with total exposure of the lead electrodes up to the fixation sleeves. The patient had a history of double-outlet right ventricle surgically corrected in 1981,…

Background. Pacemaker implantation following transcatheter aortic valve replacement (TAVR) has been linked to increased mortality. Evidence on the efficacy and safety of single-lead atrioventricular sequential (VDD) pacing in this patient population is currently limited. Purpose. We sought to assess whether TAVR patients implanted with VDD had significantly different electrical…

Background Catheter ablation is a treatment option for sustained ventricular tachycardias (VTs) that are refractory to pharmacological treatment; however, patients with fast VT and electrical storm (ES) are at risk for cardiogenic shock. Extracorporeal membranes oxygenation (ECMO) has been proposed as a useful tool for managing these procedures and…

Background. Ventricular pre-excitation, affecting 0.1-0.3% of the general population. This condition can lead to re-entrant tachyarrhythmias and, in rare cases, sudden cardiac death, even in asymptomatic individuals. Catheter ablation of accessory patway is often the resolutive treatment, however, in the pediatric population, it must be performed at highly experienced…

Background and aims: Ganglionated plexi (GPs) are the primary target of ablative therapies for neurally mediated syncope (NMS); however, the optimal method for their endocardial localization remains unclear. This study analyzed bipolar atrial electrograms (EGMs) and their response to a vagolytic agent to elucidate their relationship with the parasympathetic…
