Velocity Time Integral (VTI) Measurement of the Coronary Sinus Using Transesophageal Echocardiography During On-Pump Coronary Artery Bypass Graft (CABG) Is Useful for Assessing Treatment Effectiveness: A Case Report.
Article in Cureus, 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
In on-pump coronary artery bypass grafting (CABG) and left ventricular reconstruction, velocity time integral (VTI) measurement of the coronary sinus (CS) using transesophageal echocardiography (TEE) was useful for evaluating the therapeutic effect of coronary artery reconstruction and recovery of cardiac function. In a 56-year-old male with severe ischemic cardiomyopathy, CS VTI increased significantly from 7.06 cm at induction of anesthesia to 12.48 cm before chest closure, a favorable graft pulsatility index (<3) and improved myocardial perfusion were observed alongside. In this case, we report that the use of VTI measurement of the coronary sinus during on-pump CABG as an intraoperative assessment tool can aid in evaluating the therapeutic efficacy of coronary perfusion improvement.
