Postinfarction Ventricular Septal Defect Despite Preserved Left Ventricular Function: Management Challenges and Procedural Complications.
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
backgroundPost-myocardial infarction ventricular septal defect (PMIVSD) remains a lethal complication despite modern reperfusion. In patients with preserved or mildly reduced ejection fraction, higher shear across residual jets may increase the risk of device instability and hemolysis after transcatheter closure. CASE SUMMARY: A 48-year-old man presented with PMIVSD 15 days after chest pain. Echocardiography showed a left ventricular ejection fraction of 50% and a 13-mm apicoseptal defect. Surgery was advised but was declined. Percutaneous closure with an 18-mm muscular ventricular septal defect occluder via an arteriovenous loop was performed; however the device embolized to the right ventricular apex hours later. It was retrieved using a snared guidewire loop, and a 28-mm septal occluder was implanted. Severe intravascular hemolysis due to residual shunt developed, and despite intensive supportive therapy the patient died from septic shock. DISCUSSION: Surgery remains the preferred treatment for PMIVSD. In patients with preserved or mildly reduced ejection fraction, hyperdynamic ventricular mechanics and high left ventricular-right ventricular gradients increase risks of device embolization, residual shunt, and hemolysis after transcatheter closure. TAKE-HOME MESSAGE: Surgical repair for PMIVSD should be prioritized when feasible; if transcatheter closure is pursued, stabilization, delayed timing, and careful device sizing are essential.
