Marked Long-Term PVC Reduction During PCI for LCx CTO From the LV Summit Origin.
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
backgroundPremature ventricular contractions (PVCs) are often observed as a complication during percutaneous coronary intervention (PCI); however, it is rare for PVCs to decrease over the long-term due to procedural complications. Treating ventricular arrhythmias that originate from the left ventricular (LV) summit using catheter ablation is difficult. CASE SUMMARY: The patient experienced frequent PVCs originating from the LV summit. During PCI for a chronic total occlusion of the left circumflex artery, the PVCs reduced markedly and remained suppressed for 3 years. DISCUSSION: PVC suppression may have been caused by mechanical compression applied to the myocardium near the LV summit due to stent placement near the left main trunk (LMT) and the resulting compression from the hematoma and plaque. This rare case suggests that PCI near the LMT can interfere with arrhythmias that originate from the LV summit. TAKE-HOME MESSAGE: Arrhythmias originating from the LV summit may be suppressed during PCI for the left circumflex artery near the LMT.
