1 · What the graph read from it

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.

2 · The registry

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

backgroundOptical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) enhances treatment of complex coronary artery lesions, including left main (LM) disease, by enabling lesion morphology assessment and stent optimization, thereby reducing major adverse cardiac events (MACE).

aimsThe aim of this study was to evaluate the feasibility, safety, and mid-term outcomes of OCT-guided PCI for distal LM bifurcation lesions in the South-Asian population.

methodsThis prospective, multicenter, observational registry included 100 consecutive patients (aged 20-80 years) undergoing OCT-guided PCI for distal LM bifurcation lesions. The primary endpoint was procedural success, defined as residual angiographic stenosis of < 30%, thrombolysis in myocardial infarction (TIMI) 3 flow in all major branches, and adequate stent expansion (≥ 80%) in all vessels. Secondary endpoints included MACE, all-cause mortality, myocardial infarction, stent thrombosis, and target vessel revascularization (TVR) at 12 months.

resultsThe primary endpoint was attained in 85% of the patients. At the 12-month follow-up, MACE occurred in 1% of patients, including one (1%) cardiac mortality and one (1%) in-hospital definite stent thrombosis. No TVR or stroke was observed. The mean contrast volume used was 190.6 (71.3) mL, with significantly lower usage in the provisional stented group (174.7 mL) compared to the 2-/3-stented group (p < 0.001). The cumulative impact of OCT guidance was observed in 53% of the included patients (preprocedure: 49%, postprocedure: 13%). An extended follow-up of 18 months showed no additional MACE rates.

conclusionOCT-guided PCI was found to be safe for distal LM bifurcation lesions with good procedural success and low rates of MACE and stent thrombosis.
