Abstract:Hyperthrophic-cardiomyopathy is a genetic heart disease which causes a thickened left ventricle wall. Depending on the severity of this thickening, the blood flow into the aorta can be obstructed. When this occurs, surgical intervention is needed. The golden standard for this intervention is the septal myectomy. A septal myectomy is performed by open heart surgery, and is performed through the aortic valve. This valve is narrow, and limits the vision of the surgeon. It is hard to asses the thickness of the septal wall during the procedure. This means that not enough, or too much tissue can be removed, leading to longer surgeries and sub-optimal outcomes. Next to the fact that septal myectomies are still seen as specialized interventions, the procedure could be improved and facilitated. This research is about the development of a novel electromagnetically tracked surgical device, which can help surgeons to assess septal wall thicknesses and improve the outcome of the septal myectomy. A prototype of a novel electromagnetic guided scalpel was developed and tested. Measurements show that this prototype has adequate precision to measure the septal wall thickness for septal myectomies. With some improvements, it could potentially improve the execution and outcome of septal myectomies.
