Temporary microaxial transvalvular left ventricular assist device for post-myocardial infarction ventricular septal rupture: Bridging a paradigm shift.

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
Objective: To characterize the clinical courses and outcomes of patients presenting with post-myocardial infarction (MI) ventricular septal rupture (VSR) receiving temporary microaxial transvalvular left ventricular assist device (tVAD) support. Methods: Between December 2019 and July 2023, 10 consecutive patients presented with a post-MI VSR. All 10 patients received a tVAD. Patient characteristics, hemodynamics, intraoperative details, and postoperative outcomes were reviewed. Results: Eight patients underwent VSR repair (7 open, 1 percutaneous), and 2 patients died while on tVAD before being treated. Among the 7 patients who underwent open repair, 6 received preoperative tVAD support and 1 required intraoperative tVAD insertion during emergency right ventricular rupture repair. In the 6 patients receiving preoperative tVAD support, improvements from insertion to repair were observed in shunt fraction (from 2.6 [range, 2.3-3.3] to 1.8 (range, 1.5-3.3]), cardiac index (from 1.5 [range, 1.5-6.2] L·min Conclusions: Perioperative tVAD support for post-MI VSR acutely stabilizes hemodynamics and end-organ function, facilitating delayed intervention with reduced operative risk while also preventing futile interventions. This paradigm shift in management of post-MI VSR from emergency to urgent operations may be associated with improved outcomes.
