Impact of Three-Dimensional Imaging and Printing on Septal Myectomy Results—Single Centre’s Experience

This study aimed to assess changes in the results of septal myectomy (SM) following the introduction of three-dimensional (3D) imaging and 3D printing in surgical interventions planning and execution within a single-center setting. Between January 2007 and March 2022, 268 patients with hypertrophic obstructive cardiomyopathy underwent either conventional SM or SM with 3D heart modelling. Comparative analysis and long-term follow-up revealed that 3D modelling SM (2PSM) was associated with a lower five-year cumulative incidence of major adverse cardiovascular events and cardiac-related death. These findings suggest that SM based on 3D virtual and printed heart models is more effective than conventional SM.
