Hemodynamic Effects of Adjunct Intra-Aortic Balloon Pumping During Veno-Arterial ECMO: A Pressure-Volume Loop Study.

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
backgroundSevere ventriculo-arterial decoupling during veno arterial-extracorporeal membrane oxygenation (VA-ECMO) for refractory cardiogenic shock (CS) can be mitigated by adjunct intra-aortic balloon pump (IABP) support. The precise hemodynamic effects of IABP in this setting are however unknown. EARLY REPORT SUMMARY: This case report describes in vivo left ventricular (LV) and right ventricular (RV) pressure-volume (PV) relationships in a young patient on VA-ECMO for CS after out-of-hospital cardiac arrest due to an ST-segment elevation myocardial infarction during a sequential IABP on-off-on protocol, at both low- and high-VA-ECMO flow states. DISCUSSION: Using intracardiac PV loops at the time of VA-ECMO weaning in a patient with refractory CS, we demonstrated that adjunctive IABP: 1) reduced LV and RV afterload; 2) increased native stroke volume; and 3) in the low-flow setting only, coincided with a marked decrease in biventricular end-diastolic pressure. TAKE-HOME MESSAGE: In our patient, invasive PV loop analyses showed that IABP support reduced LV and RV afterload during high-flow V-A ECMO and decreased preload of both ventricles at low VA-ECMO flow.
