From: High risk of coronary artery obstruction during TAVR, how to avoid it?
Procedural steps for chimney stenting. A) The guide catheter was removed away from the aortic valve, the transcatheter heart valve edwards #26 was deployed. B and C) Immediate decrease in blood flow of the left system was observed post-TAVR and the coronary stent is retracted and deployed within the proximal part of the coronary artery, extending above the displaced leaflet tissue and stent frame, Chimney stent under-expansion was observed due to calcium displacement observed with IVUS
