VA-ECMO and IABP Supported CHIP-PCI for Left Main Bifurcation and CTO After Failed CABG.
Article in JACC. 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
backgroundPatients with advanced coronary artery disease, prior coronary artery bypass grafting failure, and left ventricular dysfunction represent a particularly high-risk population, especially in last remaining vessel scenarios. Complex percutaneous coronary intervention (PCI) involving left main bifurcation disease, chronic total occlusions, and severe calcification carries substantial risk of hemodynamic collapse. CASE SUMMARY: A 66-year-old man with prior coronary artery bypass grafting and ischemic cardiomyopathy presented with limiting angina and dyspnea. Coronary angiography demonstrated occluded left internal mammary artery graft, severely degenerated saphenous vein graft, chronic total occlusions of the circumflex and right coronary arteries, severe left main disease, and diffuse calcified disease of the left anterior descending artery. After heart team discussion, the patient was deemed inoperable. Complex high-risk indicated PCI was successfully performed under combined venoarterial extracorporeal membrane oxygenation and intra-aortic balloon pump support. DISCUSSION: Prophylactic mechanical circulatory support may provide hemodynamic stability and facilitate safe, complete revascularization in extreme high-risk coronary interventions. TAKE-HOME MESSAGE: In inoperable patients with advanced coronary disease and ventricular dysfunction, mechanically supported complex high-risk indicated PCI may enable safe and effective complete revascularization.
