- Abstract:
- Objective To employ three-dimensional (3D) printing model for simulating heart correct operation and summarizing its preliminarily experience for improving the surgical outcomes of various congenital heart diseases.Methods Cardiac computed tomography angiography (CTA) data of 48 children with various congenital heart diseases were selected for constructing the corresponded 3D printing models.Based on these 3D models, surgeons discussed surgical plans and simulated operative skills preoperatively.The process of real corrective procedure and the simulation were compared.Another 12 cases of tetralogy of Fallot undergoing routine surgery were selected as control group and operative durations were compared.Results The operative findings correlated well with the cardiac 3D models and the correlation between real operation and preoperative simulation of 3D printing model was satisfactory.Only 4 children’s cardiac 3D printing model slightly overestimated the diameter of pulmonary valve ring.Aortic clamp time was less in 3D group than that in control group[(47.47±9.42) vs.(55.75±9.00) min, P=0.029].Conclusion Cardiac 3D printing model may provide a feasible simulation platform for discussing and simulating surgical procedures.It can shorten operative duration and improve surgical outcomes.
