Effects of Pulmonary Resection on Right Ventricular Function

Lung resection is associated with high postoperative morbidity and mortality and leads to a significant long-term decrease in functional capacity, particularly due to cardiorespiratory complications. One of the contributing factors to this functional decline is the postoperative reduction in right ventricular function. Due to the anatomical proximity and interactions, right ventricular function is evaluated by echocardiography following lung resection. The pulmonary artery pressure (PAP)/tricuspid annular plane systolic excursion (TAPSE) ratio is a parameter that provides a more comprehensive assessment of right heart function by evaluating both right ventricular systolic function and pulmonary artery pressure. In this study, investigators aimed to evaluate changes in right heart function by performing preoperative and postoperative echocardiographic assessments in participants undergoing lung resection, focusing on PAP/TAPSE ratios.
