Is Systolic Right Ventricular Function Reduced after Thoracic Non-Cardiac Surgery? A Propensity Matched Echocardiographic Analysis

PURPOSE: To assess whether thoracic non-cardiac surgery has an influence on right ventricular function (RVF) compared to known impaired postoperative RV function after cardiac surgery. METHODS: ). All patients had transthoracic echocardiography (TTE) including two-dimensional speckle tracking (2D-STE) and tissue Doppler imaging (TDI) pre- and 1 week postoperatively. RESULTS: patients and thoracic surgery patients, only TAPSE differed between groups preoperatively (p <0.0001), where postoperatively, all RV measurements differed significantly between the two groups: TAPSE (p <0.0001), TASV (p <0.001), RVFAC (p = 0.005), and RV 2D-STE (p <0.0001) indicating impairment of RV function post-CABG surgery compared to thoracic non-cardiac surgery. CONCLUSION: Thoracic non-cardiac surgery including an opening of the pleural cavity did not influence RV function early postoperative, whereas CABG surgery with pericardiotomy led to an impaired global RV function.
