Endocarditis and other indications for open-heart surgery after a transcatheter aortic valve implant.
Observational study in Interdisciplinary cardiovascular and thoracic surgery, 2025. 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
This retrospective observational single-centre analysis included 31 patients who underwent transcatheter aortic valve implantation (TAVI) between 2016 and 2024 and subsequent open-heart surgery between 2019 and 2024. They were admitted from infectious disease departments or cardiology clinics and accounted for 0.7% of heart operations performed in 2024. The incidence of definite endocarditis was 0.5% (17/3226) of all TAVI procedures performed during this period. Of the 17 patients, 9 (53%) with definite endocarditis underwent aortic valve replacement, with 1 early death (11%) from bowel ischaemia and liver failure. The 2-year postoperative survival for definite endocarditis was 76%. Open-heart surgery was contraindicated in all 8 patients with definite endocarditis due to severe comorbidities and frailty. These patients died within 2 years of the infection or due to heart failure. Furthermore, 10 patients classified as having endocarditis after TAVI were medically treated and had a 2-year survival rate of 72%. The survival rate was 87% at 2 years after open-heart surgery for non-infectious indications performed up to 5 years after TAVI in 22 patients. In conclusion, heart surgery can be curative in selected patients with definite endocarditis after TAVI and lifesaving after rare TAVI complications.
