Left Main Obstruction From Paravalvular Leak Closure Device in Patient With Surgical Aortic Valve Replacement.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundParavalvular leak (PVL) is a relatively rare complication associated with prosthetic valve replacement, which in some cases can lead to congestive heart failure or complications of hemolysis. CASE SUMMARY: A 65-year-old man with prior surgical aortic valve replacement presented with symptoms of dyspnea, reduced left ventricular ejection fraction, and interval development of severe PVL. DISCUSSION: PVL can be managed either surgically or percutaneously. Although transcatheter closure is less invasive, it can cause rare complications such as coronary obstruction from vascular plug devices. Through this case, we show how to effectively manage such complications with coronary stenting in a patient with a large aortic PVL and low left coronary ostia. TAKE-HOME MESSAGES: Coronary obstruction is a rare but serious complication of PVL closure device. It may be caused by device position or thrombus. Assessment requires multimodality imaging. Coronary stenting can effectively manage and prevent adverse events.
