Key result
Orthopedic surgery in HOCM patients highlights the perioperative risk of exacerbating LVOT obstruction.
Why the study?
Anesthesia and surgical stress can exacerbate left ventricular outflow tract obstruction in patients with HCM and complicate the perioperative course.
Case Report (n=2)
Highlights the importance of tailored perioperative anesthesia management to prevent exacerbation of left ventricular outflow tract obstruction in patients with HCM undergoing non-cardiac surgery.
Alerts clinicians to LVOT risks during HCM noncardiac surgery; leaves optimal strategies open pending prospective data.
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.

Kankal et al. (2021) conducted a case report in Hypertrophic Obstructive Cardiomyopathy (n=2). Perioperative management was evaluated. Perioperative management of 2 patients with hypertrophic obstructive cardiomyopathy undergoing orthopedic surgery was described, highlighting the risk of exacerbating LVOT obstruction.
