Background Right ventricular (RV) dysfunction is an established independent predictor for adverse prognosis in a heterogeneous group of cardiac surgery patients (pts). However, there is lack of information about normal and abnormal dynamics of echocardiographic parameters for different types of cardiac surgery. The aim of the study was to define changes in RV parameters after cardiac surgery. Methods sixty-five pts (39 men, 62 ± 9 years old) were selected into prospective study (NCT03953755). There were the groups of pts with left-sided valves surgery with/ without tricuspid valve (TV) repair, and pts with left-sided coronary artery bypass surgery without lesions of right coronary artery were included control group. A transthoracic echocardiography assessment before and an average of 101 days (88-115) following the operation was performed. Tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC), strain of the RV free wall (SRV), and right atrial volume were assessed in groups of patients with and without tricuspid valve repair as in CABG-group. Follow-up during 12 months was available in all pts. Results Valve repair for secondary tricuspid regurgitation was performed in nineteen patients undergoing left-sided valve surgery. Thirty-six patients had repair and/or replacement of left-sided valves without a tricuspid valve operation. There was a strong correlation between TAPSE, FAC, and RV strain before the operation (R = 0.61-0.67, p Conclusion TAPSE significantly decreases in all patients after CABG or valve cardiac operations with/without tricuspid valve repair, range of TAPSE were below normal standard in all patients. However more severe decreasing in TAPSE is connected with further adverse outcomes.
