Data to accompany "Ostial versus ampulla based techniques to measure virtual valve-to-coronary distance in TAVR coronary obstruction risk"

We compared the ostial and ampulla techniques in patients screened for the TELLTALE pivotal trial of a dedicated BASILICA electrosurgery system.
Based on our findings, VTC measurements obtained using the ampulla method are more conservative than the coronary ostium method, potentially classifying more patients at risk for coronary obstruction.
