1 INTRODUCTION
A pheochromocytoma is a rare tumor that can cause serious complications
during surgery, with 25-50% of hospital deaths in patients with
unmanaged or unknown pheochromocytoma occurring during anesthesia
induction or other operative procedures.1 Herein, we
report emergency aortic valve replacement (AVR) for infectious
endocarditis (IE) complicated by a hypertensive crisis due to
unsuspected pheochromocytoma.
