The patient was 50 year-old female. She presented with stable angina. Baseline coronary angiography showed a critical stenosis of the proximal RCA with TIMI 3 flow (Figure 1, Figure 2). A 7F sheath was inserted through the right femoral artery and the right coronary was engaged with a 7F Judkins catheter. Predilatation was performed with a 3.0 x 20mm balloon at nominal pressure (Figure 3). After predilatation, following angiography showed a remained stenosis at the proximal RCA (Figure 4). A 3.5mm x 30mm Driver stent was implanted in the proximal RCA lesion at 14atm (Figure 5). The final angiogram showed a successful stent implantation in the proximal RCA without residual stenosis or dissection and the presence of TIMI 3 flow (Figure 6).

Because alloy replaces iron with cobalt as base element in the Driver stent, increased density allows thinner struts while maintaining radiopacity. We experienced from several cases that the Driver stent had several advantages, such as excellent flexibility, scaffolding, radial force, and good radiopacity. We expect that the excellent initial result of the Driver stent implantation will improve the long-term outcome compared to the stainless steel stents.
