455 Figure 1 - A) Coronary angiogram depicting a significant stenosis at the distal anastomosis of LIMA to distal LAD (white arrow). B) sirolimus-DEB inflated at the lesion after predilation. C) Final angiogram reveals excellent result (yellow arrow). Figure 2 - A) Pre-intervention OCT at the zone of the LIMA to LAD anastomosis showing a reduced lumen area about 1.0 mm 2 . B) OCT after predilation and sirolimus-DEB inflation confirming good final result at the zone of anastomosis with an excellent lumen area (6.4 mm 2 ). C) 3D reconstruction of final OCT run, showing from distal to proximal an “en face view” of the distal anastomosis of LIMA to LAD, confirming good result after Sirolimus-DEB. * denotes wire artefact.

Sirolimus-DEB at distal LIMA bypass anastomosis Int J Cardiovasc Sci. 2018;31(4)454-456 Case Report located on LIMA distal anastomosis are frequently treated with plain balloon angioplasty, but more recently DES has been widely used. The value of DEB in this setting has not been well established. Most of the evidence on the efficacy of DEB in both in- stent restenosis and de novo lesions has been generated with first generation paclitaxel-DEB. 1,2 However, this technology is continuously evolving and, currently, novel
