Introduction
Pericardial effusion (PE) is a frequent finding in patients that undergo coronary artery bypass grafting (GABG). Postoperative PE may be found in as many as 85% of patients. Although postoperative PE is a frequent finding following CABG, fortunately its course is usually benign and they randomly disappear within 7-10 days. However, in some instances PE may persist for longer and cause complications. There are currently limited data in the medical literature providing information regarding the factors that may contribute to postoperative pericarditis. We aimed to analyze the main echocardiographic characteristics that may influence the presence of PE 6 to 8 weeks following CABG.
Material and methods: This was a prospective cross-sectional study that included 90 consecutive patients that underwent CABG procedure in the Cardio Surgery Department of our tertiary medical center. We excluded patients that underwent other cardiac surgery interventions, patients with CABG that had postoperative bleeding which required reoperation and patients that had PE prior to intervention. Patients in whom PE was registered formed the first group (32 patients), whereas those without PE formed the second group (58 patients). Echocardiography data obtained before the surgery were compared between the two groups.
Results
The average amount of PE was 5.11 ± 1.62 mm. The groups did not differ in regard to gender (males 65.62% vs 63.79%, p = 0.86), age (59.59 ± 9.29 vs 61.69 ± 10.71, p = 0.35), body mass index (27.13 ± 4.05 vs 28.62 ± 4.11, p = 0.1). Comparison between groups in respect to echocardiographic features are presented in table 1. As seen in this table, left ventricular global longitudinal strain (LV GLS) was the only echocardiographic feature analyzed with statistical significance (-14.64 ± 6.86 vs -16.96 ± 4.1, p = 0.04). Both groups had mean values outside reference range, which can be explained by coronary artery disease in both groups.
Conclusions
Postoperative PE in small amount may be found in a considerable number of patients, as long as two months following CABG. More severe LV GLS alterations may be associated with occurrence of PE in patients following CABG. Abstract Figure. Comparison of echocardiographic features
