Recurrent syncope in a child and video assisted thoracoscopic surgery - The long and short of it

Abstract

Long QT syndrome (LQTS) is a myocardial repolarisation disorder caused by cardiac ion channelopathy and one of its common presentations is recurrent syncope. This reduced repolarisation reserve in LQTS can be unmasked by perioperative factors like electrolyte imbalance, drugs, hypothermia and changes in cardiac autonomic tone. We report the anaesthetic management of left thoracoscopic sympathectomy in a 5-year-old child with LQTS and epicardial pacemaker in situ. It is very challenging to isolate the lung on one hand and prevent the predisposition to torsadogenic potential on the other.
