Many intra-cardiac interventions employ minimally invasive approaches, where instrumentation is introduced into the chambers via the vascular system or heart wall. One such procedure involves the trans-apical repair of a mitral-valve leaflet. Using Augmented Reality, we demonstrate dramatically increased performance over the standard of care, reducing total navigation time and total tool path lengths by factors of 4 and 5 respectively, as well as a significantly decreasing dangerous incursions of the instrument within the heart.
