A dislodged coronary stent migrating over a guiding catheter: a "Muckers-type" stent loss retrieved using a snare technique.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCoronary stent dislodgement is a rare complication of percutaneous coronary interventions with potentially serious clinical sequelae. There are several scenarios for the dislodgement and various techniques to deal with this complication. A dislodged stent migrating retrogradely over a guiding catheter and retrieved with a snare system has never been reported. We present the first reported case of a dislodged coronary stent passing over a guiding catheter which was successfully retrieved with a snare system. CASE REPORT: A 76-year-old patient with unstable angina was admitted for a coronary angiography. It revealed in-stent restenosis in the mid portion of the left anterior descending artery (LAD) and within the ostium of the left main coronary artery (LM). Following an uncomplicated PCI of the LAD and during subsequent stent deployment in the LM, the balloon with a mounted stent popped out to the aorta. After the balloon had been pulled back, the stent migrated over the guiding catheter. Consequently, another longer stent was successfully implanted into the LM, and afterwards the dislodged stent was snared and retrieved using an ipsilateral femoral access. The patient was discharged after two days of uneventful hospital stay.
conclusionsThe case report demonstrates an unusual course of stent dislodgement passing over a guiding catheter which was successfully retrieved with a snare technique. It underscores the importance of optimal lesion preparation and meticulous vigilance when implanting short stents into LM.
