Stent-Related Infective Endocarditis Revealing Aortic Cusp Perforation on Intraoperative TEE: A Case Report Altering Surgical Strategy.
Article in Annals of cardiac anaesthesia, 2026. 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
abstractCoronary stent infective endocarditis (IE) is a rare but serious complication of percutaneous coronary intervention. Extension to adjacent valvular structures, particularly causing cusp perforation of the aortic valve, is exceedingly uncommon. Intraoperative transesophageal echocardiography (TEE) may reveal complications not detected preoperatively, thereby changing surgical plans. We report a patient who underwent coronary angioplasty followed by persistent fever and suspicion of stent infection. Angiography detected stent related left anterior descending artery aneurysm and preoperative plan for stent explantation and revascularization was made. However, on the operating table, intraoperative TEE demonstrated perforation of the right coronary cusp of the aortic valve with severe aortic regurgitation. Surgical strategy was modified to include stent explantation, coronary artery bypass graft (CABG), and aortic valve replacement. The stent specimen showed evidence of infection. The patient's postoperative course was favorable under targeted antibiotic therapy. This case illustrates how intraoperative TEE can uncover unanticipated valvular destruction in stent-related IE and meaningfully alter surgical decision-making. Early recognition, imaging vigilance, and flexibility in surgical planning are essential in management of such rare but high-risk complications.
