Abstract Quadricuspid pulmonary valve is a rare abnormality which has been reported in isolation or with structural ehart diseases. We report a neonate who presented with supra-ventricular tachycardia and Wolff-Parkinson-White syndrome who had a structurally normal heart. The recognition of a phasic ejection click on clinical examination led to the identification of a normally functioning quadricuspid pulmonary valve

Appropriate Therapy

Background: Tetralogy of Fallot (TOF) is the most frequent form of congenital heart disease managed by EP physicians for potential ICD. However, few studies have reported long-term outcomes of TOF patients with ICD. Methods: Between 2005 and 2014, all TOF patients with ICD in 17 French centers were enrolled in a specific evaluation aiming to determine characteristics at implantation as well as outcomes (overall mortality, appropriate ICD therapies, and device-related complications). Results: Overall 78 patients (45±13 years, 64% males) were enrolled. A majority of patients were implanted in the setting of secondary prevention (73%), whereas the remaining (27%) in primary prevention. Among the latest group, known risk factors for sudden cardiac death were: severe pulmonary regurgitation (30%,) prior palliative shunt (50%), syncope with unknown origin (25%), inducible ventricular tachycardia (45%), QRS duration ≥180ms (18%), non-sustained ventricular tachycardia (25%), and documented sustained supra ventricular tachycardia (45%).Overall, patients implanted in the setting of primary prevention presented with a mean of 3.1±1.4 risk factors. After a mean follow-up of 4.9±3.8 years, 35 patients (45%) experienced at least one appropriate therapy (25% in the primary prevention group compared to 53% in the secondary prevention group), giving annual-incidences of 6.9% (95%CI 0.14-13.7) and 21.3% (12.4-30.3) respectively (P=0,01). The mean time between ICD implantation and the first appropriate therapy was 2.2±3.2 years, without significant differences between primary and secondary prevention. Overall, ≥one ICD-related complication occurred in 30 patients (38%), including inappropriate shock (n=9), major pocket hematoma (n=1), lead dysfunction (n=12), infection (n=4), shoulder algodystrophia (n=2), device failure or dislodgement needing reintervention (n=2). Eventually, four patients were transplanted (5%), and six patients (8%) died during the course of follow-up. Conclusions: Considering relatively long-term follow-up, patients with TOF and ICDs experience high rates of appropriate ICD therapies, in both primary and secondary prevention. Major ICD-related complications remain, however, high.

Abstract Hyperthermia is defined as an elevated body temperature above the normal range due to a failure of heat regulatory mechanisms. In addition to its effects on other organ systems, hyperthermia is associated with profound cardiovascular effects. We report the sentinel case of a 6-year-old girl with structurally and electrically normal heart, who presented with life-threatening hyperpyrexia-induced ventricular tachycardia, which was refractory to cardioversion and anti-arrhythmics but responded promptly to cooling. We emphasise the lifesaving role of immediate and aggressive cooling in such patients.
