Primary percutaneous coronary intervention was done in a patient with acute anterior wall myocardial infarction and a 2.75 x 30 mm Endeavor Resolute stent (Medtronic) was deployed in the mid-left anterior descending. A 3 mm non-compliant balloon catheter was used for postdilatation. While positioning, the postdilatation balloon catheter got stuck in the middle of the stent and after some manipulation it went through. In the next cine frame, it was apparent that the stent had lengthened distally (Figures 1A and 1B). Stent VIZ (Figure 1C) showed stretching of the distal half of the stent. Postdilatation was completed with the 3 mm balloon with good angiographic results except the stretching of the stent. Optical coherence tomography (Figures 2A-2H) shows a considerable segment of the artery in the distal half of the stent denuded with well-apposed stent elsewhere.
