Hemodynamic Effects of Concomitant Mitral Valve Surgery and Left Ventricular Assist Device Implantation.
Article in ASAIO journal (American Society for Artificial Internal Organs : 1992), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
There are conflicting data regarding whether concomitant mitral valve surgery (MVS) at left ventricular assist device (LVAD) implantation is beneficial. This study aimed to assess the hemodynamic effects of concomitant MVS. Of all 73 enrolled patients, 44 patients had undergone concomitant MVS and 29 patients had not. Before LVAD implantation, MVS group had higher pulmonary capillary wedge pressure (p = 0.04). After LVAD implantation, MVS group had higher mean pulmonary artery pressure and cardiac output (CO). During the hemodynamic ramp study, MVS group had steeper CO slopes (0.18 [0.13 0.28] vs. 0.15 [0.08, 0.20] L/min/step; p = 0.04) at incremental LVAD speed and achieved a higher CO at the optimized set speed (5.5 [4.7, 6.9] vs. 4.9 [4.0, 5.7] L/min; p = 0.03). One-year freedom from death or heart failure readmission was statistically comparable between the two groups (61% vs. 80%, p = 0.20). Thus far, after LVAD implantation and concomitant MVS, patients had increased pulmonary hypertension, despite having higher CO and a better response of CO at incremental LVAD speed. The implication of hemodynamic features after concomitant MVS on clinical outcomes warrants further investigation.
