Medical Simulations for a Patient-specific Clinical Practice

ther evidence on the feasibility of implants, as well as advise engineers about the risk of structural issues. At the University College London’s Institute of Cardiovascular Science and the Great Ormond Street Hospital for Children (London, UK), this technique has fostered a better understanding of episodes of device fractures, supported the first implant of a novel device for percutaneous pulmonary issues in a human, and explored the potential of minimally invasive alternatives for patients suffering from a failing bioprosthetic aortic valve.

In the future, our aspiration is a more extensive implementation of medical simulations in clinical practice. A multidisciplinary approach of this kind can open the doors to safer and more effective procedures tailored to the characteristics of every patient.

explored to assess the success of the procedure in a large population of patients (Figure 2). The best placement strategy and the distribution of stress were assessed. Results from the computational model are validated by bench experi-

ments (Figure 3) and clinical results, supporting the reliability of the computational findings. In general, the outcomes of these simulations can provide clinicians with fur-

Higher Order Performance Assessments Using Error Enabled Simulations: A New Approach By Carla M. Pugh & Janis Cannon-Bowers In the operating room environment, mastery of surgical skills requires both technical excellence and excellence in operative decision making. Recognizing and correcting errors for both of these skills is a vital component of surgical training. When the goal of training is achievement of expertise, deliberate practice should be strategically incorporated as part of the learn-

“Surgical procedure simulators that allow for error prevention, error recognition and error rescue offer training opportunities that may exceed those possible in the live setting as error avoidance and patient safety trump trainee independence.”
