Microaxial Left Ventricular Assist Device as Bridge to Transplantation in Postinfarction Left Ventricular Pseudoaneurysm.

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
backgroundLeft ventricular (LV) pseudoaneurysm is a rare complication of myocardial infarction (MI) that may present with cardiogenic shock. CASE SUMMARY: A 61-year-old man who had experienced MI 1 month prior presented with recurrent cardiogenic shock. Transthoracic echocardiography and cardiac magnetic resonance imaging revealed a large apical LV pseudoaneurysm compressing the right ventricle. Given prohibitive surgical risk, the patient was supported with prolonged Impella 5.5 therapy while awaiting heart transplantation. He remained hemodynamically stable throughout support and ultimately underwent successful heart transplantation. DISCUSSION: Management of LV pseudoaneurysm typically involves surgical repair or conservative surveillance; however, literature describing prolonged mechanical circulatory support in this population remains sparse. This case demonstrates the feasibility of extended Impella support as a bridge to transplantation in a patient with post-MI LV pseudoaneurysm and cardiogenic shock. Impella-assisted LV unloading may mitigate aneurysmal wall stress, serving as a temporizing strategy in select high-risk patients. TAKE-HOME MESSAGE: Prolonged Impella support may represent a viable bridge to heart transplantation in patients with LV pseudoaneurysm and cardiogenic shock who are unsuitable for surgical repair or durable left ventricular assist device therapy.
