Association between aortomitral continuity calcification and conduction disturbances following transcatheter aortic valve implantation with the balloon-expandable Myval valve.
Article in Journal of arrhythmia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: Given the anatomical proximity of the cardiac conduction system, aortomitral continuity calcification (AMCC) may contribute to conduction disturbances (CD) during transcatheter aortic valve implantation (TAVI) due to radial force on the AMCC. This study aimed to investigate the impact of AMCC on new-onset CD in patients undergoing TAVI with the balloon-expandable Myval valve. Methods: This retrospective study included 160 patients who underwent TAVI. AMCC was assessed using Agatston and calcium volume scores from preprocedural computed tomography (CT). Multivariable logistic regression was used to identify independent predictors of CD. Results: High-grade atrioventricular block (HAVB) occurred in 13.1% of patients, and 17.5% required permanent pacemaker implantation (PPM). Patients with HAVB and PPM exhibited a higher prevalence of AMCC and significantly higher AMCC scores. An AMCC score >180 was an independent predictor of HAVB (OR, 5.58; 95% CI, 1.43-21.70; Conclusion: AMCC is a strong independent predictor of HAVB and PPM following TAVI, particularly with scores >180 or when AMCC is anatomically close to the RFT. Preprocedural CT-based assessment of AMCC burden and proximity may improve risk stratification and procedural planning.
