Abstract
Right ventricular dysfunction is a common and clinically significant complication in patients undergoing coronary artery bypass grafting (CABG), and is closely associated with postoperative mortality and adverse cardiovascular events. Therefore, accurate assessment of right ventricular function plays a crucial role in postoperative monitoring and risk stratification. Echocardiography is a widely used imaging modality in clinical practice that allows evaluation of right ventricular systolic and diastolic function and provides important hemodynamic information following surgery. The aim of this review is to update and systematically summarize the current evidence regarding the application of echocardiography in the assessment of right ventricular function in patients after CABG, as well as to analyze the clinical and prognostic value of echocardiographic parameters in the postoperative setting. This review focuses on the principal echocardiographic techniques, including conventional two-dimensional echocardiography, tissue Doppler imaging, hemodynamic parameters related to pulmonary artery pressure, and myocardial deformation imaging for the assessment of right ventricular strain.
