Establishing a digital archive of three-dimensional, holographic heart models, from a collection of abnormal hearts to serve as educational tools for clinicians and students, for the study of congenital heart disease.
Surgery
The repair of congenital heart defects first became possible in the 1960s, and Killingbeck Hospital in Leeds was a pioneering centre. However, in the early years, congenital heart problems were poorly understood and could often not be repaired. To improve the outcomes of cardiac surgery, Dr Leon Gerlis established a collection of hearts with defects which was used for training by cardiac surgeons. The so-called Gerlis collection remains very important for education. However, modern laws make it difficult to use the collection and novel methods of education about congenital heart problems are needed. This does not only apply to surgical training but increasingly also to patients and parents who require a better understanding of congenital heart disease.
Over recent years it has become possible to make virtual copies of the many different objects, including the heart. The copies that are made can replace the original hearts, and multiple copies can be produced for use in education and research.
In the initial part of the project, Ms Van Doorn and her team will obtain digital images of the Gerlis Collection by performing Magnetic Resonance Imaging (MRI) scans of the hearts. The scans will be stored in a computer, and this will become a digital archive of the original collection. They will then develop further computer programmes to reconstruct 3D models of the hearts for use in education.
Depending on the computer programme, the virtual Gerlis heart models can be displayed in a variety of ways, such as in mobile phones Apps, holograms, or as 3D printed models. The team is keen to develop educational resources that are suitable for a wide range of learners and subsequently will seek extensive input from future users for the optimal design of their programme. The first heart model that will be developed is a hologram. However, as the information in the virtual Gerlis archive can be used many times again, it will be possible to continue to develop many new heart models and adapt these to the needs of individual users.
This project will open the Gerlis collection to many different groups for training and teaching. The digital archive will also enable access for research groups to further their understanding of congenital heart disease or help design new treatments.
The development of a new AI-supported model for imaging the heart based on data from over 700 people with atrial fibrillation, allow ablation to be more personalised to individual patients.
Personalised angina care
Bringing together patients and medical professionals to establish a partnership aimed at identifying areas of priority in adult cardiac surgery, to better inform clinicians and make heart surgery safer for patients.
Developing an AI-assisted computer programme to identify whether a conduction system pacing (CSP) procedure has been successful, which will allow more patients to benefit from this innovative pacemaker technology.
