AbstractHypertrophic obstructive cardiomyopathy (HOCM) involves marked hypertrophy of cardiac muscle, resulting in myocardial ischemia and arrhythmia because of left ventricular diastolic dysfunction. In perioperative management of HOCM, hemodynamic stabilization is required, by prevention of arrhythmia and tachycardia and maintenance of preload and afterload. Here, we describe anesthesia management during cesarean section in a patient complicated by HOCM. The patient was a 27-year-old woman who underwent elective cesarean section scheduled at 36 weeks of pregnancy given her history of HOCM. She was managed with spinal anesthesia with monitoring of invasive blood pressure and arterial pressure cardiac output. Administration of landiolol hydrochloride was initiated, because of paroxysmal tachycardia after delivery. Approximately 5 min after initiation of administration, her heart rate decreased gradually and blood pressure rose. Circulatory dynamics stabilized and landiolol was discontinued 3 h after she was admitted to the intensive care unit. Her circulatory dynamics remained stable after discontinuation of landiolol, and she was moved to a general ward on the following day. She was discharged on postoperative day 14, with her child.
