Successful recanalization of a calcified, collateral-poor LAD-CTO via repeat antegrade dissection and re-entry guided by intravascular ultrasound after prior subintimal plaque modification: a case report.
Article in BMC cardiovascular disorders, 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
backgroundChronic total occlusion (CTO) of the left anterior descending artery (LAD) with poor collateral circulation poses significant procedural challenges. Subintimal plaque modification (SPM) followed by repeat antegrade dissection and re-entry (ADR) under intravascular ultrasound (IVUS) guidance may enhance recanalization success. CASE PRESENTATION: A 53-year-old male with prior non-ST-elevation myocardial infarction underwent failed initial percutaneous coronary intervention (PCI) for a stump-free, heavily calcified LAD-CTO with poor collaterals. After SPM, repeat angiography at 3 months revealed improved vessel architecture. IVUS-guided ADR was successfully performed, achieving full revascularization. At 4-year follow-up, the patient remained asymptomatic without major adverse cardiac events (MACE).
conclusionIn complex LAD-CTO lesions, SPM combined with IVUS-guided repeat ADR represents a viable bailout strategy, particularly when conventional antegrade/retrograde approaches fail.
