Anesthesia concerns in patients with hypertrophic obstructive cardiomyopathy posted for orthopedic surgery

Abstract

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiovascular disorder, characterized by asymmetric hypertrophy of the interventricular septum that leads to intermittent obstruction of the left ventricular outflow tract (LVOT). Clinical presentation ranges from the absence of symptoms to sudden death at any age. Anesthesia and surgical stress can lead to exacerbation of the LVOT obstruction and may complicate the perioperative course. We hereby describe the perioperative management of two patients with HCM posted for orthopedic surgery.
