OBJECTIVES: This study sought to predict whether different methods of calculating the implantation depth (ID) influence clinical and hemodynamic outcome reporting in patients undergoing transcatheter aortic valve replacement (TAVR) with a self-expandable device.

BACKGROUND: Different approaches exist to calculate the ID, which may influence uniform and reliable reporting because the updated Valve Academic Research Consortium (VARC-2) criteria do not provide specific instructions.

METHODS: The clinical and hemodynamic outcomes of 258 patients undergoing TAVR with a third-generation self-expandable device were analyzed with regard to the method used to assess the ID as follows: arithmetic mean, the arithmetic mean of the measured distances from the noncoronary cusp and the left coronary cusp to the distal prosthesis end; noncoronary cusp distance, the distance from the noncoronary cusp to the distal prosthesis end; and deepest edge, the deepest edge of the distal prosthesis end.

RESULTS: Regardless of the measurement method, the optimal ID (OID) was reached in

CONCLUSIONS: The OID was reached in
