Brief summary
BACKGROUND Right ventricular dysfunction is a common echocardiographic finding after cardiac surgery. Pericardial disruption has been suggested as the most probable cause as the phenomenon occurs within minutes after pericardial incision. The investigators suspect that validated two-dimensional echocardiographic measures for right ventricular function might not reflect the altered RV contraction pattern including paradoxical interventricular septal motion and reduced long-axis function following open cardiac surgery. The present study aims to determine the prevalence and scale of right ventricular dysfunction two years after CABG by applying the latest available two- and three-dimensional echocardiographic technology in right ventricular evaluation. In addition, the investigators investigate the impact of right ventricular dysfunction on functional outcome. METHODS The Right-Heart-Study is an observational substudy of the SWEDEGRAFT trial at Aarhus University Hospital in Denmark. SWEDEGRAFT is a nordic, multicenter, prospective, randomized, register-based, clinical trial (ClinicalTrials.gov Identifier: NCT03501303; Ragnarsson 2020). Patients for the current Right-Heart-Substudy will be recruited amongst the 269 patients included in the SWEDEGRAFT trial at Aarhus University Hospital from 10 September 2018 to 25 May 2020. Patients are enrolled at the time of SWEDEGRAFT follow-up with cardiac-CT (approximately 30 months after CABG). After written informed consent, we perform additional full 2D and 3D echocardiography with special focus on RV function, collect patient-reported data on functional outcome, and measure brain natriuretic peptide and hemoglobin levels.
