Transcatheter Edge-to-Edge Mitral Valve Repair Device Embolization into the Right Lower Pulmonary Vein.

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
backgroundExcellent efficacy and safety have led to an increase in transcatheter edge-to-edge repair (TEER) procedures. MitraClip embolization into the pulmonary veins has not yet been reported in the literature. CASE SUMMARY: A 77-year-old man in cardiogenic shock with severe mitral regurgitation underwent a MitraClip procedure. Deployment of a second MitraClip was complicated by knotting of the locking threads. Attempts to release these threads led to embolization of the MitraClip into the right lower pulmonary vein. Transesophageal echocardiography-guided retrieval using a gooseneck snare through a multipurpose catheter led to safe clip removal. DISCUSSION: MitraClip embolization is a rare event that complicates up to 0.1% of cases. This is to our knowledge the first case report on embolization into the pulmonary veins. Lock-thread failure as the mechanism for embolization is uncommon. Our retrieval assembly, consisting of a gooseneck snare through a long multipurpose catheter then through the MitraClip steerable catheter, provided adequate reach, torque, and maneuverability for safe retrieval. TAKE-HOME MESSAGES: The pulmonary veins are a rare location for MitraClip embolization. Appropriate catheter selection and optimal grasp orientation are key to event-free retrieval.
