Agua KM, et al. - Whether the impact of age, right ventricular (RV) size and RV function on in-hospital mortality and on the clinical course during the intensive care unit (ICU) stay could predict postoperative mortality and morbidity during the preoperative period was determined in 70 patients, with preoperative cardiac magnetic resonance imaging (MRI) scans, who had undergone tricuspid valve (TV) repair (n=57) and TV replacement (n=13) for Ebstein’s anomaly. In this retrospective analysis, patients with preoperative cardiac MRI scans, who were operated on from 2005 to May 2018, were included. Death or the need for extracorporeal membrane oxygenation were mainly assessed, additionally, postoperative inotropic therapy, ventilation time, renal failure and duration of ICU stay and hospital stay were evaluated. Findings revealed certain factors that were helpful to detect patients with an increased perioperative risk. These factors were RV end-diastolic volume index >200 ml/m², RV-ejection fraction (EF) <40% and age >50 years. Earlier surgery was suggested to offer more favourable outcomes in patients with Ebstein’s anomaly.
