| Sumario: | Seventy-four-year-old male patient admitted with non-ST-elevation acute myocardial infarction. The coronary angiography performed revealed the presence of right coronary artery stenosis with a giant coronary artery aneurysm (CAA) and high thrombus burden (figure 1A). Dual antiplatelet and anticoagulation therapies were recommended for its exclusion in a staged procedure. After confirmation of thrombus reduction (figure 1B), predilatation was attempted and both the length of the CAA (40 mm) and the landing zone were measured on the intravascular ultrasound (IVUS) (figure 1C). From proximal to distal, two 5 mm x 26 mm-PK-Papyrus covered coronary stents (PCS) (Biotronik, Switzerland) were deployed. The overlapping stent zone was confirmed using the StentBoost imaging modality (Philips Medical Systems, Nederland) (figure 1D) and the stent was deployed under fluoroscopic guidance in the absence of any respiratory movements. The subsequent angiography performed revealed an incomplete CAA exclusion (figure 1E) despite postdilatation with a 5.5 mm noncompliant balloon (NCB). The IVUS confirmed the existence of a gap between both stents due to stent shortening (E2, figure 1E and video 1 of the supplementary data). Another 5 mm × 15 mm PCS was deployed followed by postdilatation with a 5.5 mm NCB. Both the angiography and the IVUS confirmed the... |
