A coronary pseudostenosis is a characteristic angiographic image, which may appear as coronary winkles, or intussusceptions, due to a stiff guidewire during coronary interventions. Intravascular ultrasound (IVUS) plays a role in ruling out severe coronary stenosis, coronary dissections, thrombus or coronary spasm. We report a case of coronary pseudostenosis, which occurred during coronary interventions, diagnosed by intravascular ultrasound.
