Simulation may provide a solution to acquire advanced skills in thoracic surgery, however to date there are no reports in the English literature about a perfused ex vivo model. We developed a low cost and hi fidelity model using an ex vivo in bloc heart and lung specimen from a swine. The swine was previously used in a non-thoracic experiment, so we extracted the lung and heart for this ex vivo based model to reduce animal use. The cost of the whole model is 70 USD and it can be reused many times changing the ex vivo tissue, so this model may help reduce the costs and animal use associated to this high complexity surgery.
