Abstract

Congenital long QT syndrome (LQTS) is a potentially lethal but highly treatable channelopathy. Along with multiple risk reduction measures, a recommendation for left sympathetic cardiac denervation therapy and/or implantable cardioverter defibrillator is made for higher risk patients. Despite its relatively common incidence in paediatric patients, there are no formal recommendations regarding perioperative management and discharge criteria for LQTS patients undergoing ambulatory surgery. This report describes a 17-year-old girl, diagnosed with congenital LQTS at 9 years of age, who had an episode of ventricular fibrillation the day after elective ear, nose and throat surgery. Despite several risk factors, she had a same-day dismissal, was not adequately monitored postoperatively and her cardiologists were not notified of her procedure. For the high-risk LQTS patient, we recommend monitoring of perioperative electrolytes and rhythm, postoperative ECG, adequate β-blockade therapy, avoidance of particular pharmacological agents, consideration of overnight observation and communication with the patient's cardiologist prior to procedure, and at discharge.
