Cardiac surgery transformation throughout the COVID-19 era: analysis of 12,409 patients.
Article in Irish journal of medical science, 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
backgroundPrevious studies documenting COVID-19's impact on cardiac surgery have been limited by short observation periods, small sample sizes, and lack of recovery pattern analysis.
aimThis study aims the comprehensive analysis of complete pandemic cycles, utilizing Türkiye's graduated restriction model as a natural experiment to examine cardiac surgery transformation and recovery patterns.
methodsWe conducted a retrospective analysis of 12,409 consecutive patients from March 2018 to February 2024, encompassing three equal 24-month periods: pre-pandemic, pandemic, and postpandemic. Our institution maintained non-COVID status throughout the pandemic. The pandemic period was subdivided into three phases by restriction severity (early, intermediate, late) to analyze adaptation patterns.
resultsAmong 12,409 patients, emergency surgery rates doubled during pandemic (6.5%→12.7%, p <0.001). CABG procedures became dominant (64.2% vs 57.3%, +6.9 percentage points, p <0.001) while valve surgery declined (-4.8 percentage points). Although overall patient age increased (+1.0 years, p <0.001), isolated CABG patients showed minimal progression (+0.4 years), revealing age increases were driven by deferred non-CABG procedures. BMI remained stable across periods (p =0.291). Emergency rates peaked during early pandemic (14.4%) before gradual recovery. Postpandemic period demonstrated successful recovery with valve surgery reaching unprecedented levels (p <0.001).
conclusionsThis represents one of the largest single-center series (12,409 patients over 72 months) and provides insights that may inform future pandemic preparedness strategies in cardiac surgery. The successful post-pandemic recovery validates graduated restriction strategies over complete service suspension, offering critical insights for maintaining CABG capacity while implementing systematic valve surgery backlog management strategies during future health emergencies.
