	abstract = {A 73-year-old man with severe aortic valve stenosis successfully underwent transcatheter aortic valve replacement (TAVR) using CoreValveTM (29 mm, Medtronic Inc., Minneapolis, MN, USA). Four years after the TAVR, he was hospitalized due to anterior ST-segment elevation myocardial infarction. Despite the need for prompt restoration of coronary flow in the infarct-related artery, the implanted CoreValveTM profoundly restricted the manipulation of diagnostic catheters during the coronary angiography. In particular, (I) guidewire easily migrated into the space between CoreValveTM and aorta vessel wall; (II) the nickel-titanium frame of CoreValveTM limited the space to manipulate catheters, making difficult to advance Judkins left (JL) 4, Judkins right (JR) 4 and Amplatz left 1 into coronary cusps; and (III) selecting specific spot within frame was required for cannulation. Left and right coronary arteries were barely engaged by JL3.5 and modified JR4, respectively. Percutaneous coronary intervention (PCI) for culprit lesion in the left-anterior descending artery was successfully completed by 6-French JL3.5 (BritetipTM, Cordis, Milpitas, CA, USA) with drug-eluting stent implantation. Meticulous strategies and understanding of the prosthetic valve geometry are warranted to conduct PCI in patients who underwent TAVR.},
