Hypothesis
To evaluate the feasibility, effectiveness and assistant effect of 3D printed aortic model in the treatment on congenital coarctation of the aorta (CoA) in adolescents and adults.
Conclusion
Percutaneous balloon dilatation covered stent implantation is effective in the treatment of adolescents and adults with CoA in the short and medium term, with fewer complications.
Supporting Evidence
- All patients with CoA were successfully treated with percutaneous balloon dilatation covered stent implantation.
- The narrowest average diameter of CoA increased from 4.35 mm to 16.84 mm immediately after operation.
- The mean transconstrictive systolic pressure difference decreased from 81.29 mmHg to 15.52 mmHg after operation.
- The mean systolic blood pressure of the right upper limb decreased from 182.05 mmHg to 141.95 mmHg postoperatively.
- The mean systolic blood pressure of the lower limb increased from 121.52 mmHg to 131.81 mmHg postoperatively.
Takeaway
Doctors used 3D printing to make models of patients' aortas to help plan surgeries for a heart problem called coarctation of the aorta, and it worked well.
Methodology
Patients underwent percutaneous balloon dilatation covered stent implantation, with preoperative 3D printed models used for surgical planning.
Limitations
The long-term effects of the treatment need further study.
Participant Demographics
