The prognostic value of preoperative CAD-RADS classification in patients undergoing isolated aortic valve surgery.

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
To investigate the association between preoperative coronary artery disease (CAD) severity, as classified by the Coronary Artery Disease Reporting and Data System (CAD-RADS), and clinical outcomes in patients undergoing isolated aortic valve replacement (AVR). A total of 897 patients (452 women; mean age, 66.1 ± 9.3 years) who underwent isolated AVR and preoperative coronary computed tomography angiography (CCTA) between 2004 and 2022 were stratified by the CAD-RADS score. The outcomes of interest were all-cause death and major adverse cardiac and cerebrovascular events (MACCE). The CAD-RADS score was 0 in 290 (32%) patients, 1 in 208 (23%), 2 in 255 (29%), 3 in 82 (9%), and 4 in 62 (7%) patients. The rates of all-cause death and MACCE tended to increase in parallel with CAD-RADS score (4%, 10.5%, 8.2%, 18.2%, 28.1% at 5 years and 14.4%, 15.1%, 16.7%, 26.9%, 38.4% at 5 years, both P < 0.001). CAD-RADS score ≥ 3 was associated with a higher risk of all-cause death (HR 2.44, 95% CI: 1.52-3.93) and MACCE (HR 1.79, 95% CI: 1.27-2.52) after adjusting for potential confounders. Notably, patients with CAD-RADS ≥ 3 who received medical therapy in addition to coronary angiography (CAG) improved overall survival compared to those who did not undergo CAG. Preoperative CCTA with CAD-RADS assessment would be useful for screening concomitant CAD and predicting long-term clinical outcomes including all-cause death and MACCE in patients undergoing isolated AVR. For patients with CAD-RADS ≥ 3, it is essential to implement medicinal therapy or intervention along with CAG.
