Can aortic valve calcium score predict a need for permanent pacemaker implantation after transcatheter aortic valve implantation?
Article in Open heart, 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
introductionConductive disturbances requiring permanent pacemaker (PPM) implantation remain a major concern after transcatheter aortic valve implantation (TAVI).
aimsTo assess the impact of aortic valve calcium score (AVCS) on conductive disturbances requiring PPM after TAVI.
methodsAll patients who underwent TAVI with accessible AVCS from the preprocedural CT scan report were included in this retrospective single-centre study. The primary endpoint was the occurrence of a conductive disturbance requiring PPM at 30 days. The association between PPM and AVCS, with its incremental prognostic value, was analysed using multivariable logistic regression, receiver operating characteristic curve analysis and likelihood ratio (LR) test.
resultsWe included 761 patients of which 125 (16%) required PPM at 30 days. AVCS score was significantly higher in patients requiring PPM (3788 (2487-5218) vs 3050 (2043-4367) AU, p<0.001). Using multivariable analysis, preprocedural right bundle branch block (RBBB) (OR 6.61, 95% CI 3.82 to 11.5, p<0.001), first atrioventricular block (OR 1.71, 95% CI 1.03 to 2.83, p=0.037), self-expanding valve (OR 3.25, 95% CI 1.17 to 9.09, p=0.025) and AVCS>4510 AU (OR 1.83, 95% CI 1.04 to 3.20, p=0.035) were independently associated with PPM. AVCS had an incremental discriminative value (C-index 0.79 vs 0.77, LR test p=0.036) over and above traditional PPM risk factors. An algorithm was proposed based on the initial presence of RBBB, AVCS and the type of implanted valve.
conclusionEven if RBBB remained the strongest predictor of PPM post-TAVI, this study suggests that a high AVCS may help identifying patients at increased risk of PPM after TAVI, especially among those without pre-existing RBBB.
