Introduction
Video supplement to “A Phantom Lesion in the Left Main Coronary Artery: Concertina Effect,” by Parashar, et al. (November 2021 Clinical Images).
Classically described in tortuous coronaries, the concertina effect is a type of pseudostenosis induced by guidewire and is extremely rare in the left main coronary artery because of its short length.

The following video series demonstrates this rare phenomenon.
