The RCA was pre-dilated sequentially with a compliant 2.0 mm and non-compliant (NC) 2.5 mm balloon. However, the lesion was inadequately expanded (Fig. 15.4; Videos 15.3 and 15.4). Two runs of rotablation were then performed using a 1.5 mm burr (Fig. 15.5; Video 15.5), which helped to better prepare the lesion. This was followed by stenting with two overlapping 3.5 mm drug-eluting stent placement and post-dilation with NC 3.5 mm balloon. Video 15.6 show the well-expanded DES in RCA.
