KeywordsCongenital Heart Disease Aortic Arch Test Dataset Preclinical Test Assisted Method
Introduction and purpose
To optimize outcome in congenital heart disease, the aim is to establish computer assisted methods for planning and simulating surgery in an objective and quantitative manner.
Based on 3D MRI datasets, two applications were developed: (1) for surgical correction of hypoplastic aortic arches the calculation of vessel diameters, and a patch for optimal surgical correction. This application was evaluated on 12 test datasets and phantoms. (2) For assessing the feasibility of biventricular repair in the case of complex cardiac malformations, an application for simulation of intracardiac repair with a Rastelli like procedure was developed and tested.
The calculation of patch material for surgical reconstruction of aortic pathologies is possible from 3D MRI data and first preclinical tests were successful. For complex cardiac malformations, the preoperative evaluation of the operation method will be feasible. Further preclinical testing is needed.
