Restoring Ventricular Geometry: Left Ventricular Reconstruction in a Patient with a Giant Left Ventricular Aneurysm and End-Stage Heart Failure.

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
Post-infarction left ventricular aneurysm is an uncommon but severe mechanical complication of transmural myocardial infarction, particularly in patients with delayed presentation or incomplete myocardial salvage. It may lead to profound distortion of left ventricular geometry, adverse remodelling, intraventricular thrombosis, mitral regurgitation, pulmonary hypertension, and advanced heart failure. We report the case of a 65-year-old male patient referred two months after a late-presenting anterior ST-segment elevation myocardial infarction caused by proximal occlusion of the left anterior descending coronary artery. At admission, the patient presented with severe decompensated heart failure, low-output status, multiorgan dysfunction, and a left ventricular ejection fraction of 12%. Transthoracic echocardiography and cardiac magnetic resonance imaging demonstrated a giant apical left ventricular aneurysm involving approximately 75% of the ventricular cavity, partial intraluminal thrombosis, extensive transmural scarring in the left anterior descending territory, and imaging features suggestive of a chronic contained free-wall rupture/pseudoaneurysmal component. Following multidisciplinary evaluation, the patient underwent surgical ventricular reconstruction using an endoventricular circular restoration technique guided by an intraventricular balloon sizer, combined with left internal thoracic artery bypass grafting to the left anterior descending artery. The early postoperative course required temporary inotropic, vasopressor, inhaled nitric oxide, and intra-aortic balloon pump support, followed by progressive haemodynamic recovery. The patient was discharged on postoperative day seven with functional improvement to NYHA class II. At six-month follow-up, he remained clinically stable without overt signs of heart failure, and echocardiography showed preserved ventricular geometry and improvement of left ventricular ejection fraction to 45%. This case highlights the potential role of carefully planned, balloon-guided surgical ventricular reconstruction in selected patients with giant post-infarction left ventricular aneurysms and end-stage heart failure when residual viable myocardium is present.
