Direct Cardiac Compression Device for Short-Term Mechanical Circulatory 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
Patients requiring short-term ventricular assistance have limited options. While not all interventions necessarily require blood-contacting support, all current devices are invasive and interact with the bloodstream. Direct cardiac compression (DCC) devices offer a potential solution by providing mechanical circulatory support (MCS) without contact with the bloodstream. This proof-of-concept study compares a novel DCC patch device for short-term MCS to open-chest cardiac compression (OCCC) using an ex vivo ovine cardiac arrest (CA) heart model. Performance is evaluated by assessing pressure, flow rate, and valve functionality, as well as any damage to the tissue. In the CA model, the device achieves 1.5 L/min cardiac output and a mean aortic pressure of 55 mm Hg. Despite direct epicardial contact, the DCC patch device maintains effective valve function. This study demonstrates that the DCC patch device achieves comparable performance to OCCC, supporting previous in vitro findings. Our results suggest the potential for this novel DCC patch device to be applied across a range of short-term MCS scenarios.
