Diagnosis of congenital and acquired Gerbode defects by cardiac MRI: two cases.
Article in Radiology case reports, 2026. 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
The Gerbode defect is a rare left ventricle-to-right atrium shunt, often misdiagnosed as tricuspid regurgitation, and may be either congenital or acquired. We report two cases: one acquired Gerbode defect following redo mechanical mitral valve replacement surgery, presenting with dyspnea and progressive heart failure; and one incidental congenital Gerbode defect in an asymptomatic patient. In both cases, Cardiac Magnetic Resonance (CMR) clarified shunt anatomy and informed management decisions. The first patient underwent successful percutaneous closure under Digital Subtraction Angiography (DSA), while the second received conservative follow-up due to the absence of symptoms. CMR complemented echocardiography by delineating anatomical features, particularly when acoustic windows were limited, and supported post-treatment evaluation.
