Spontaneous Coronary Artery Dissection Presenting as Sustained Ventricular Tachycardia: A Rare and Life-Threatening Manifestation.
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
backgroundSpontaneous coronary artery dissection (SCAD) is a rare and often overlooked cause of acute coronary syndrome. Most cases present with myocardial infarction, and initial presentation with sustained ventricular tachycardia (VT) is exceedingly uncommon. CASE SUMMARY: A 65-year-old man presented with sustained monomorphic VT and hypotension. After successful cardioversion, elevated cardiac biomarkers prompted further evaluation. Coronary angiography with optical coherence tomography confirmed SCAD of the proximal left anterior descending artery. The patient underwent percutaneous coronary intervention with drug-eluting stent placement. Cardiac magnetic resonance imaging revealed dilated cardiomyopathy with apical thrombus. DISCUSSION: VT in SCAD results from ischemia due to intramural hematoma or dissection. Intracoronary imaging plays a vital role in confirming diagnosis and guiding management in atypical cases.
conclusionsThis case highlights the importance of considering SCAD in the differential diagnosis of unexplained VT, particularly in patients without diffuse coronary artery disease, and it emphasizes the role of advanced imaging and early intervention in improving clinical outcomes.
