Isolated Posterior Mitral Valve Cleft Diagnosed by 3D Echocardiography in an Elderly Woman.
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
backgroundIsolated posterior mitral valve cleft (MVC) is a rare congenital anomaly that can be easily overlooked with standard 2-dimensional imaging. CASE SUMMARY: A 94-year-old woman with progressive heart failure symptoms was found to have severe mitral regurgitation due to an isolated posterior MVC. Three-dimensional echocardiography provided detailed visualization of the lesion's anatomy and confirmed the diagnosis. After excluding a percutaneous repair due to the cleft's complexity, she underwent minimally invasive surgical repair, resulting in substantial symptomatic improvement. DISCUSSION: Posterior MVCs are infrequently reported and often missed by conventional imaging. Advances in 3-dimensional echocardiography have enhanced diagnostic accuracy, guiding targeted interventions. This case shows the importance of comprehensive imaging for such rare anomalies and the feasibility of surgical repair, even in elderly patients.
