Estudio comparativo del tratamiento quirúrgico de la miocardiopatía hipertrófica obstructiva en función del empleo o no de un modelo 3D. Experiencia de nuestro centro

Abstract

Introduction and aimSurgical treatment of hypertrophic cardiomyopathy faces challenges related to the extend and depth of septal resection. Three-dimensional printing presents itself as a useful tool in surgical planning, providing a visual and tangible representation of the surgical field. This study aims to compare surgical outcomes in patients with hypertrophic obstructive cardiomyopathy, depending on whether or not a 3D model was used. MethodsA retrospective observational study was performed in 55 patients with surgical indication for obstructive hypertrophic cardiomyopathy between May 2017 and May 2022 at Cruces University Hospital (Spain). A homogeneity analysis was performed between groups, followed by a comparative analysis to assess surgical success according to improvement in functional class, presence of complications associated with septal myectomy, reduction in interventricular gradient and mortality. ResultsA 3D model was used as a complementary tool in 18 patients. Functional class improved in both groups, but was more pronounced in the 3D model group. No patient in the 3D group showed a significant interventricular gradient, whereas 20% of the no-model group did. Complications were more prevalent in the no 3D model group (40.54% vs. 11.11%). At 30 days, mortality was lower in the 3D model group (5.56% vs. 11.16%). ConclusionsThe use of 3D models improves surgical planning and reduces complications in septal myectomy.
