Clinical Features and Outcomes of Surgically Treated Infective Endocarditis in Adults with and Without Congenital Heart Disease: A 12-Year Cohort Study.
Article in Journal of cardiovascular development and disease, 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
backgroundAdults with congenital heart disease (CHD) are at markedly increased risk of infective endocarditis (IE); however, data comparing clinical characteristics and outcomes in surgically treated IE patients with and without CHD remain limited. This study aimed to evaluate differences in clinical profile, microbiology, complications, and outcomes between these groups.
methodsWe conducted a retrospective cohort study of 773 adult patients who underwent surgery for IE at a tertiary center in China between October 2013 and August 2025. Patients were categorized into CHD (
resultsPatients with CHD were significantly younger and had fewer cardiovascular comorbidities than non-CHD patients. CHD was associated with a higher prevalence of right-sided and multivalvular infection, whereas non-CHD patients predominantly had left-sided disease. Streptococcus species were the most common pathogens in both groups, with no significant intergroup differences in microbiological profiles. After IPTW adjustment, no significant differences were observed in major postoperative complications, length of stay, or early mortality. Overall and in left-sided IE, long-term survival was comparable between groups, whereas in right-sided IE, patients with CHD appeared to have more favorable long-term survival (HR = 0.17, 95% CI: 0.04-0.66,
conclusionsDespite distinct clinical characteristics, adults with and without CHD undergoing surgery for IE had similar overall outcomes, although CHD was associated with better long-term survival in right-sided IE.
