Delayed presentation of traumatic giant left anterior descending artery pseudoaneurysm as acute coronary syndrome and cardiogenic shock: 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
backgroundCoronary artery pseudoaneurysms are rare vascular abnormalities that may develop after percutaneous coronary intervention, infection, or trauma. Although many cases remain asymptomatic, pseudoaneurysms may occasionally present with life-threatening complications. Delayed presentation of traumatic coronary pseudoaneurysm as acute coronary syndrome (ACS) complicated by cardiogenic shock is extremely uncommon. CASE PRESENTATION: A 74-year-old man presented with chest pain, dyspnea, hypotension, and signs of cardiogenic shock. Electrocardiography demonstrated anterior myocardial infarction. Emergency coronary angiography revealed proximal occlusion of the left anterior descending artery (LAD) associated with a giant pseudoaneurysm and severe circumflex artery stenosis. Given the patient's hemodynamic instability and high surgical risk related to multiple comorbidities, percutaneous treatment was selected. Following restoration of coronary flow, a covered stent was implanted to seal the pseudoaneurysm. Subsequently, complex bifurcation intervention using the double kissing crush technique was performed. Residual pseudoaneurysm filling was completely eliminated with prolonged balloon inflation. Further history revealed a motor vehicle accident five months before presentation, suggesting a presumed traumatic etiology. The patient recovered uneventfully and was discharged on the fifth day.
conclusionsThis case highlights an unusual delayed presentation of traumatic giant LAD pseudoaneurysm as ACS complicated by cardiogenic shock. Careful clinical history taking may help identify traumatic etiologies. Complex percutaneous coronary intervention with covered stent implantation may represent a feasible treatment option in carefully selected high-risk patients.
