Type 1 long QT syndrome is the most common long QT syndrome genetic subtype. Exercise and emotional stress can precipitate sudden cardiac events in patients with type 1 long QT syndrome; however, the precise mechanism remains elusive. We report the case of a teenage girl with type 1 long QT syndrome secondary to a rare frameshift mutation (p. L191fs+90X) in the KCNQ1- encoded Kv7.1 potassium channel. During emotional distress, her continuous QTc recordings precipitously increased, peaking within...

Background Intracardiac echocardiography (ICE) is commonly used during interventional cardiac catheterization in adults, but data regarding the use of ICE in children are limited. There are no data available comparing the effectiveness of preprocedural transthoracic echocardiography (TTE) with that of intraprocedural ICE in predicting atrial septal defect (ASD) size and rim adequacy for percutaneous closure in a pediatric population. The objectives of this study were to describe the investigator...

Cardiogenic seizures are common and could be the sentinel event heralding the presence of congenital long QT syndrome (LQTS). Distinguishing a cardiogenic seizure from a neurogenic one is of the utmost importance. Herein, we present the case of a 12-year-old boy with recurrent episodes of syncope and seizures. Despite absence of QT prolongation on electrocardiogram, absence of documented arrhythmias, a negative LQTS genetic test, and recurrent episodes while on nadolol beta-blocker therapy, he w...

Hypertrophic cardiomyopathy (HCM) is marked by profound phenotypic and genotypic heterogeneity. Systolic anterior motion (SAM) of the anterior mitral leaflet is a classically described feature of HCM but its genetic predilection is unknown. Our study cohort consisted of 213 (74 male, mean age 51
