Supine positioning in patients with hypertrophic obstructive cardiomyopathy (HOCM) can affect their preload, afterload, and heart rate, potentially leading to cardiovascular collapse. Here, we report the successful anesthetic management of two patients with HOCM who underwent spinal surgery in a prone position. The approximate values of the systemic vascular resistance index (SVRI) were continuously calculated without measuring the central venous pressure. Intraoperative monitoring of the SVRI estimates may be helpful in patients with HOCM so as to avoid cardiovascular collapse when monitoring with both transesophageal echocardiography and a central venous catheter is clinically inappropriate.
