Practice and clinical outcomes of valvular surgery for rheumatic heart disease in africa: a scoping review.
Article in Journal of cardiothoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundRheumatic heart disease is prevalent in Africa, but advanced cardiac care for the condition, which includes valve surgery, is limited. This study examined rheumatic heart disease surgical management and clinical outcomes in Africa.
methodsThis study followed the PRISMA Extension for Scoping Reviews (PRISMA-ScR) guidelines. We conducted a comprehensive search of PubMed, Embase, Scopus, and Web of Science for keywords related to “rheumatic heart disease,” “valve surgery,” and “Africa.” Clinical studies published in African countries on valve surgery for rheumatic heart disease were included.
resultsThe review included 17 studies from 10 countries. The prevalence of rheumatic heart disease had a female predominance (n = 1313/2367, 55.5%). Mitral valve procedures were universally reported. 7 studies highlighted moderate to severe valve disease severity. Clinical improvement was noted in two studies, with patients in NYHA Class I or II. Reoperation rates varied from 1.45% to 17%, and mortality rates from 3.85% to 22.67%. Hospital stays ranged from 5 to 16 days, and ICU stays from 2 to 3 days. Post-operative complications included thromboembolic disease, hypertrophic scars, infective endocarditis, left ventricular dysfunction, bioprosthetic valve dysfunction, arrhythmias, and neurological events such as stroke.
conclusionValve surgery for rheumatic heart disease in Africa shows promising clinical outcomes but faces challenges like outcome variability, postoperative complications, and limited infrastructure. Addressing diagnostic issues, enhancing follow-up care, and building healthcare capacity are essential for expanding effective surgical interventions and improving patient outcomes.
