Since the preoperative echocardiogram showed left ventricular hypertrophy and LVOTO, preoperative fluid loading was performed over 2 days to optimize fluid volume. For anesthesia induction, the ramp position helped maintain airway patency. Intraoperative and postoperative hemodynamics were generally stable, and hypertension during tumor manipulation was managed by titrating sevoflurane concentration.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>An excessive cortisol level with Cushing syndrome can rarely cause LVOTO in an infant.
