How to make an aortic root replacement simulator at home

Abstract

There is a paucity of low-fidelity and cost-efficient simulators for training cardiac surgeons in the aspects of aortic root/ valve replacement. In this study we addressed this training challenge by creating a low-fidelity, low-cost but, at the same time, anatomically realistic aortic root replacement simulator for training purposes. We used readily available, low cost materials such as lint roller tubes, foam sheet, press-and-seal bags, glue, plywood sheet, heat-shrink sleeving tubes and condoms as the basic material to create a low-fidelity, aortic root, training simulator. We constructed a multi-purpose, anatomically realistic aortic root simulator using the above materials, both time- and cost-efficiently, using the minimum of surgical equipment. This simulator is easy to construct and enables self-training in major techniques of aortic root replacement as well as in stentless valve implantation for trainees in cardiac surgery.
