Mark M. P. van den Dorpel, from Erasmus University Medical Center in Rotterdam, the Netherland, talks about pre-procedural planning at our masterclass in Rotterdam in October 2022. He discusses pre-procedural planning for large-bore access. Pre-procedural should take into account minimal required vascular diameter, amount and location of calcification, prior vascular interventions/surgery, tortuosity, and location of bifurcation in femoral artery.
