Fetal Long QT Syndrome: Case Series and Literature Review With Focus on Multidisciplinary Care Coordination.

Congenital long QT syndrome (LQTS) is a group of heritable conditions that are associated with cardiac repolarization abnormality characterized by QT prolongation on ECG and risk of life-threatening arrhythmias. Prenatal detection of LQTS presents many challenges for clinicians and a multidisciplinary approach is needed for optimal prenatal and postnatal management. We describe five cases of fetal diagnosis of LQTS with variable initial presentation, diagnostic strategies, and management approaches. A multidisciplinary team approach including fetal cardiologist, adult and pediatric electrophysiologists, medical physicists, neonatologists, maternal-fetal medicine specialists, fetal cardiac nurse coordinators, and genetic counselors allowed for comprehensive prenatal management and well-planned postnatal treatment to optimize neonatal and maternal outcomes.
