This video describes a surgical technique to treat severe symptomatic obstructive hypertrophic cardiomyopathy (HCM) through a median sternotomy. This technique is mainly inspired from the morrow septal myectomy.  The video highlights the main anatomical landmarks that drive the surgical resection and that must be kept in the surgeon’s mind to allow for a safe and efficient surgical procedure. Finally, the video discusses when it is advisable to add an edge-to-edge mitral stich during the modified Morrow myectomy and demonstrates how to do so.
