Genetic variants for long QT syndrome among infants and children from a statewide newborn hearing screening program cohort
2014, Journal of PediatricsCitation Excerpt :Approximately 40% of the individuals with repeat QTc values <450 ms were younger than 1 year of age. Possibly, these infants had transient QTc prolongation.31 However, the individual with the largest decrease (55 ms) and the highest initial QTc value (487 ms) was a 5-year-old boy (Table II).
Long QT syndrome in neonates: Conduction disorders associated with HERG mutations and sinus bradycardia with KCNQ1 mutations
2004, Journal of the American College of CardiologyCitation Excerpt :Recent reports of LQTS with functional 2:1 AVB have been related to homozygous mutations in HERG(8–11)or SCN5A(14). Three infants with homozygous HERGmutations had a prolonged QTc, with functional 2:1 AVB with one sudden death in utero, whereas heterozygous carriers in the family had a normal phenotype (8–11). The child with a homozygous SCN5Amutation was not symptomatic during the first month of life and was older at diagnosis (14).
Cardiac pathology in sudden unexpected infant death
2002, Journal of PediatricsCitation Excerpt :Finally, cardiac pathologic features are common when sudden death occurs in an infant who was awake at the time of death. The spectrum of cardiac pathologic features found at autopsy in our series is representative of the various causes of sudden death in infants and children outlined in numerous reports.10-35 A notable addition to this list would be our two cases of massive hemopericardium secondary to spontaneous rupture of an arteriovenous malformation of coronary vessels in the posterior atrioventricular groove.
