Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy.
Article in Catheterization and cardiovascular interventions : official journal of the Society for Cardiac Angiography & Interventions, 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
backgroundManagement of heavily calcified coronary lesions remains challenging despite advances in plaque-modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no-reflow. CASE SUMMARY: A 75-year-old woman with non-ST-segment elevation acute coronary syndrome and severe left ventricular dysfunction, previously treated with thoracic radiotherapy, underwent percutaneous coronary intervention of a calcified left anterior descending artery lesion. Optical coherence tomography revealed an eruptive calcified nodule with thrombus and a concentric stenosis. ELCA was selected to minimize distal embolization; however, the procedure was complicated by multiple coronary perforations requiring covered stent implantation. DISCUSSION: This case suggests that coronary perforation during ELCA may result from the interplay between lesion complexity, procedural factors, and radiation-related vessel wall remodeling.
