Abstract;The patient of this case was a 58-year-old woman with acute dissociated aortic aneurysm complicated with hypertrophic obstructive cardiomyopathy (HOCM). She was difficult to recover from ardiopulmonary bypass for emergency surgery of the aneurysm. So, peraortic myocardial resection was additionally carried out perioperatively. When recovery from coardiopulmonary bypass was attempted under the treatment with dobutamin, blood flow became unstable and ventricular tachycardia developed. However, per-aortic cardiomuscular resection was conducted based on the findings of per-esophagus echo, leading to the recovery from it. Per-esophagus echography was demonstrated to be effective for pathoclinical evaluation during the surgery for aortic aneurysm complicated with HOCM.
