Direct visualisation of the BASILICA technique post TAVR to enhance coronary flow

Obstruction of blood flow to the coronary arteries during transcatheter aortic valve replacement (TAVR) is a potentially fatal complication that occurs in ~2.3% of valve-in-valve procedures. Many patients identified at risk of coronary obstruction remain too high a risk for open heart surgery and their treatment is limited to palliative care. In May 2017, a collaboration between the National Institutes of Health (NIH) and the University of Washington developed an electrosurgery catheter-based technique, to slice the leaflets ...
