Heart Block in Pregnancy From Parvovirus B19.
Article in JACC. 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
backgroundComplete heart block is a rare and possibly life-threatening condition in pregnancy, requiring timely recognition and multispecialty management. CASE SUMMARY: This case report describes a previously healthy pregnant woman who developed high-grade atrioventricular block due to a parvovirus B19 infection. Before her presentation, she had a upper respiratory infection with a "slapped cheek" rash, classic for parvovirus B19. Other cardiac, infectious, and rheumatologic etiologies were excluded. She had subsequent recovery of atrioventricular conduction with conservative management. DISCUSSION: Although congenital heart block is a known fetal complication of parvovirus B19, maternal cardiac conduction abnormalities linked to this virus have not previously been documented. Patients with heart block during pregnancy should be managed similarly to those who are not pregnant; however, caution should be exercised when using fluoroscopy for pacemaker placement. TAKE-HOME MESSAGE: This case highlights the importance of a broad differential diagnosis, a multidisciplinary approach, and appropriate maternal-fetal risk stratification in the management of cardiac arrhythmias during pregnancy.
