Successful Sealing of Steam Pop-Related Left Ventricular Summit Perforation With Partial Impella Support.

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
backgroundImpella is effective for left ventricular (LV) rupture after myocardial infarction. However, its role in managing LV perforation during catheter ablation in structurally normal hearts, particularly at the LV summit, remains unclear. CASE SUMMARY: A 69-year-old woman developed LV perforation due to a steam pop during ablation for premature ventricular contractions. After emergency surgery, the pseudoaneurysm persisted despite intra-aortic balloon pump (IABP) support and multifactorial management. The IABP was then replaced with Impella CP, and the pseudoaneurysm later closed spontaneously. The patient recovered without sequelae. DISCUSSION: LV summit perforation caused by steam pops is challenging to manage because of the anatomical complexity and tissue fragility. Although the favorable outcome was likely multifactorial, Impella support may still have contributed to the overall management strategy despite the small, nondilated LV and support being limited to performance level 2 (P2). TAKE-HOME MESSAGE: Pseudoaneurysm after LV perforation may be managed with multifactorial therapy, including partial Impella support.
