Hypertrophic Obstructive Cardiomyopathy
Conditions
Interventions
Experimental Group:3D-Printed Cardiac Model-Assisted Septal Myectomy
Pre-operative Planning:
An individualized cardiac model (typically made of flexible photopolymer resin) will be 3D-printed at a 1:1
Control group:Conventional Septal Myectomy
Pre-operative Planning:
The surgical team will rely solely on conventional two-dimensional echocardiography, cardiac CT, or MRI images for pre-operative anal
