Optimal Operative Strategies in Repair of Giant Coronary Artery Aneurysms: Case Presentation.
Article in Surgical case reports, 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
introductionSurgical exclusion of giant coronary artery aneurysms (GCAAs) complicated by coronary-to-left ventricular (LV) fistulae requires a definitive strategy to obliterate the abnormal communication while maintaining myocardial integrity. We report 2 surgical cases focusing on internal orifice closure. CASE PRESENTATION: In Case 1 (80-year-old male), a calcified left circumflex artery-GCAA was managed by direct internal closure of the aneurysm neck and LV fistula. The procedure focused on isolating the aneurysm from the coronary circulation, with an auxiliary left internal thoracic artery-obtuse marginal (LITA-OM) graft to ensure distal flow. In Case 2 (39-year-old male), the extensive GCAA required a Hemashield patch (GETINGE, Göteborg, Sweden) for internal closure of the left coronary ostium. Simultaneously, the LV fistula was closed from within the aneurysm. Although postoperative LV unloading via percutaneous cardiopulmonary support (PCPS) and Impella (Abiomed, Danvers, MA, USA) was required, the core surgical success was achieved through complete internal exclusion of both the fistula and the coronary inlet.
conclusionsFor GCAAs with LV fistulae, the primary surgical objective should be the integrated internal closure of the fistula and the coronary ostium. This approach effectively excludes the aneurysm and prevents recurrence.
