Coronary artery disease and outcomes following transcatheter aortic valve implantation.
Observational study in Open heart, 2024. 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
backgroundAortic stenosis is a life-limiting condition for which transcatheter aortic valve implantation (TAVI) is an established therapy. Coronary artery disease (CAD) is frequently found in this patient group and optimal management in these patients remains uncertain.
objectivesWe sought to examine the association of coexistent CAD on mortality and hospital readmission in patients undergoing TAVI.
methodsIn this observational cohort study, we examined patients who underwent TAVI and segregated them by the presence of obstructive epicardial CAD. The primary outcome was 3-year mortality with secondary outcomes being readmission for (1) all-causes, (2) a MACE (Major Adverse Cardiovascular Event) composite endpoint and (3) acute coronary syndrome. Subsidiary outcomes included patient angina and breathlessness scores.
results898 patients underwent TAVI, of which 488 (54.3%) had unobstructed coronary arteries and 410 (45.7%) had obstructive CAD. Overall, n=298 (33.2%) patients experienced the primary mortality endpoint with no significant difference when stratified according to CAD (n=160 (32.9%) vs n=136 (33.2%), HR 0.98, CI 0.78 to 1.24). After multivariate analysis, the presence of CAD had no effect on the primary outcome (HR 0.98, CI 0.68 to 1.40). There was no significant difference in readmission for any cause (n=181, 37.1% (CAD) vs n=169, 41.2% (no CAD), p=0.23), including no significant difference on readmission for MACE (n=48, 9.8% (CAD) vs n=45, 11.0% (no CAD), p=0.11). CAD at the time of TAVI also did not alter breathlessness or angina scores before/after TAVI (p>0.05).
conclusionCoexistent CAD had no significant association with mortality, any-cause readmission or symptoms for patients undergoing TAVI in our cohort.
