We experienced the perioperative management of a patient with hypertrophic obstructive cardiomyopathy, who underwent open heart surgery. We performed three kinds of overload examinations, which included overdrive test using the pacemaker, continuous dopamine infusion with overdrive test and continuous diltiazem infusion with overdrive test, before and after cardio-pulmonary bypass under observation of the cardiac performances with transesophageal echocardiogram. We gained some important and interesting informations about the cardiac reserve of the patient. We could perform adequate perioperative management for the patient, taking the results of overload examinations into consideration.
