Prognostic impact of small size sutureless prostheses: results for 241 patients from an international registry.
Article in Journal of cardiothoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02679404 (Sorin Universal REgistry on Aortic Valve Replacement), which is not on this 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.

Abstract
backgroundThe treatment of aortic valve disease in small annuli remains a debated topic in terms of prosthetic choice - biological or mechanical - and risk of patient prosthesis mismatch.
methodsThe clinical data of the 241 patients who received a small size sutureless prosthesis from the Sorin Universal REgistry on Aortic Valve Replacement (SURE-AVR) (NCT02679404) were analysed at 30 days and at follow-up. The mean age was 75.5 ± 7.8 years (89.2% female); the mean Society of Thoracic Surgeons (STS) score was 4.2 ± 3.2%, and the preoperative NYHA class II or III score was 83.8%. A minimally invasive approach was performed in 52.7% of patients; concomitant procedures were performed in 27.8% of patients. Similar aortic clamping and cardiopulmonary bypass times were observed in the overall isolated cohort and the isolated minimally invasive cohort. The mean intensive care unit (ICU) stay was 2.4 ± 2.0 days and the total length of stay was 10.3 ± 6.1 days.
resultsThree deaths were recorded at 30 days (1.2%), 2 for noncardiac causes. One patient experienced a myocardial infarction (0.4%) and 2 a nondisabling stroke (0.8%). 2 patients showed intraprosthetic leakage ≥ 2 and one patient para-prosthetic leakage ≥ 2; of these, one patient required reoperation with prosthesis removal. 4.1% of patients required a pacemaker implant. At a maximum follow-up of 8.1 years, 10 cardiovascular deaths, 4 valve related reinterventions (3 structural valve deterioration (SVD) requiring TAVI Valve-in-Valve, 1 endocarditis) occurred.
conclusionsWith their good clinical outcomes, sutureless prostheses represent a good alternative for patients with small annuli, who are at high risk for annular enlargement and anticoagulant therapy.
