The Emergency Resection of a Mobile Left Ventricular Thrombus in Dilated Cardiomyopathy: A Case of Multiorgan Embolism and Postoperative Ventricular Tachycardia.
Article in Cureus, 2025. 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
Dilated cardiomyopathy (DCM) is characterized by marked left ventricular (LV) dilation and systolic dysfunction, which predispose patients with DCM to LV thrombus (LVT) formation and potentially fatal multiorgan embolism. We report the case of a 52-year-old male with severe DCM (ejection fraction (EF), 14%; LV diameter, 89 mm) who developed a large, mobile LVT (40 × 30 mm) that caused embolic events in the lungs, kidneys, spleen, superior mesenteric artery, and posterior cerebral cortex. Since anticoagulation therapy was deemed insufficient to control the embolic source, emergency surgical thrombectomy was performed via an apical LV incision. Although the patient's condition initially stabilized, he developed ventricular tachycardia and torsades de pointes on postoperative day (POD) nine, which led to cardiac arrest. He was successfully resuscitated but required intensive antiarrhythmic therapy and circulatory support. The patient was discharged on POD 41 with an implantable cardioverter-defibrillator. This report illustrates that surgical removal of a large, mobile LVT is effective in controlling embolic events; however, an LV incision may induce postoperative life-threatening ventricular arrhythmias due to myocardial scarring and electrical heterogeneity. Rigorous perioperative monitoring and comprehensive arrhythmia management are essential when surgical thrombectomy is considered for LVT related to DCM.
