A patient was referred to our department with suspected aortic angiosarcoma. We visualized and reconstructed the computed tomography and magnetic resonance imaging scans of this patient to create finite-element multidimensional models of his diseased aorta. This technique and the multidimensional models were very helpful in assessing the tumor size and its extension. It also facilitated preoperative planning of the aortic resection and repair. Finite-element multidimensional modeling is a useful technique for preoperative planning of aortic operations in patients with angiosarcoma.

We propose a low fidelity simulator to enhance the comprehension of the aortic root and the enlargement procedures. Methods We used self-constructed models to simulate the aortic root. The related structures were constructed. Aortomitral angle of 120 degrees was created in the models. We performed three enlargement procedures 1. Manougian 2. Nicks 3. Nunez. Manougian and Nunez incisions were made through the commissure between the left and the Non coronary cusps (NCC) where Manougian extended through the anterior leaflet of the Mitral Valve (AML) while Nunez stopped proximal to the anterior annulus of the mitral valve. Nick’s incision was carried out through the middle of the NCC and also extending through the AML. Enlargements were carried out with a Dacron patch. Results Self constructio...
