Posterior left pericardiotomy for prevention of re-thoracotomy and postoperative atrial fibrillation in aortic surgery.
Article in Interdisciplinary cardiovascular and thoracic 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
objectivesRe-thoracotomy due to pericardial effusion is a frequent complication after aortic surgery, leading to prolonged intensive care unit (ICU) and hospital stays and adverse outcomes. This study aims to evaluate the frequency of re-thoracotomy and postoperative atrial fibrillation in patients undergoing ascending aorta replacement with or without posterior left pericardiotomy.
methodsWe retrospectively analysed clinical data from patients who underwent elective ascending aorta replacement with or without aortic root between January 2014 and June 2024. Patients were divided into two groups based on posterior left pericardiotomy. We assessed re-thoracotomy due to bleeding or pericardial effusion, postoperative atrial fibrillation, ICU and in-hospital stay, as well as mortality rates, adjusting for confounders using propensity score matching.
resultsA total of 256 patients could be included (n = 140 without and n = 116 with posterior left pericardiotomy). Mean age was 61.6 ±12.2 years, with 27.7% female patients. After matching, re-thoracotomy (12.9% vs 3.4%; P = 0.007) and postoperative atrial fibrillation (36.4% vs 16.4%; P = 0.011) were higher in patients without pericardiotomy. Thirty-day and 1-year mortality were 1.3% and 4.2%, respectively. Posterior left pericardiotomy was associated with shorter ventilation time (8.0 vs 15.0 hours; P < 0.001) and hospital stay (8.0 vs 12.0 days; P < 0.001). Similar results were observed between the unmatched and the matched cohort.
conclusionsPosterior left pericardiotomy is a simple surgical manoeuvre associated with lower rates of re-thoracotomy and postoperative atrial fibrillation in elective aortic surgery patients in a retrospective cohort. Further prospective randomized trials should be performed to confirm and highlight the results from our study.
