    Coronary Pleating Mimicking Coronary Ruptures, Dissections, and Thrombi on Optical Coherence Tomography

    Introduction Straightening of tortuous coronaries by intracoronary guidewires may generate intimal wrinkles or coronary pleating and lead to the development of different abnormal angiographic findings widely known as pseudostenosis or accordion effect. 1 We report the unique findings disclosed by optical coherence tomography (OCT) in 3 patients developing coronary pleating. Patient 1 An 84-year-old woman with severe aortic stenosis was referred for coronary angiography before transcatheter aortic valve implantation. A severe stenosis in the mid segment of the right coronary artery was treated with a bare metal stent. The guidewire induced a new moderate focal lesion at the most proximal ...
