Severe myocardial ischaemia during mask induction of anaesthesia in an infant with unknown critical supravalvular aortic stenosis.
Congenital supravalvular aortic stenosis is an uncommon type of aortic obstruction. When critical, it represents an extreme variant of outflow tract obstruction with increased risk of cardiovascular instability during exercise or anaesthesia. We present a case of severe myocardial ischaemia during induction of anaesthesia with sevoflurane in a 3-month baby with a presumed diagnosis of valvular aortic stenosis for which a percutaneous balloon dilatation of the aortic valve was scheduled.
