General anesthesia was given to six surgical patients with hypertrophic cardiomyopathy on eight occasions from 1990 to 1992. Anesthetic courses were uneventful in five patients diagnosed previously as hypertrophic cardiomyopathy. ⋯ A slight hypotension caused by epidural anesthesia had a devastating effect on the patient. The above experiences stress the importance of early diagnosis and careful observation in perioperative period.
