Association Between Post-Cardiopulmonary Bypass Hemodynamics and 30-Day Mortality After Aortic Surgery: A Single-Center, Retrospective Study

Background: We evaluated phase-specific associations between perioperative hemodynamic variables and 30-day mortality following aortic surgery requiring cardiopulmonary bypass (CPB) and to assess the utility of post-CPB variables in risk stratification. Methods: We analyzed 691 patients who underwent aortic surgery req...

AI-Powered Preoperative Chest Radiograph-Derived Cardiovascular Border Indices and Risk of Postoperative Major Adverse Cardiovascular Events: A Large-Scale Retrospective Cohort Study

Background and Objectives: Routine preoperative chest radiography (CXR) has limited value for perioperative risk prediction when interpreted qualitatively. The Automated Diagnosis of Cardiovascular abnormalities (ADC) model enables automated quantification of cardiomediastinal vascular border (CVB) parameters on CXR. T...
