Left Ventricular Assist Device Implantation in Patients with Previous Open-Heart Surgery: Comparison of Median Sternotomy and Lateral Thoracotomy.
Article in Brazilian journal of cardiovascular surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionReoperative cardiac surgery is associated with a higher risk of complications due to technical difficulties compared to the first-time surgery. This study aims to compare the early outcomes of median sternotomy (MS) and lateral thoracotomy (LT) procedures in patients with a history of previous open-heart surgery who underwent left ventricular assist device (LVAD) implantation with cardiopulmonary bypass (CPB).
methodsA retrospective analysis was conducted on 36 patients who received LVAD implants for end-stage heart failure between November 2012 and June 2015. The patients were divided into Group 1 (MS, n = 18) and Group 2 (LT, n = 18).
resultsThe mean age of the patients was 57.2 ± 9.4 years (range: 24 - 70 years), and only 8.3% were female. Demographic data, preoperative characteristics, use of blood products, anesthetic drugs, and complications were similar in both groups (P > 0.05). The MS group had significantly longer operation duration (101 ± 46 minutes vs. 70 ± 20 minutes, P = 0.038) and CPB time (328 ± 79 minutes vs. 265 ± 47 minutes, P = 0.048) compared to the LT group. Postoperative analgesic consumption and pain scores were similar between the two groups (P > 0.05).
conclusionIn patients with a history of previous cardiac surgery, LVAD implantation with LT through CPB demonstrated favorable outcomes regarding reduced operation duration and CPB time. However, it did not positively impact the duration of stay in the intensive care unit, hospital stay, use of blood products, and complications.
