Coronary obstruction is a rare but potentially fatal complication of transcatheter aortic valve replacement (TAVR). It can result from native leaflet or stent frame obstruction of the coronary ostia. There are reports detailing the difficulty of percutaneous coronary intervention following TAVR, but none that describe a periscope approach to access the left main ostia in the presence of a braided nitinol frame. This report describes an alternative approach to access a coronary artery when the valve stent struts are prohibitive to equipment delivery.
