Post-CPB RV dysfunction in infants may warrant monitoring despite preserved LV function; leaves open whether TDI-guided strategies improve outcomes.

Does open heart surgery with cardiopulmonary bypass alter right and left ventricular regional myocardial function measured by tissue Doppler imaging in infants and neonates?
Tissue Doppler imaging reveals significant right ventricular systolic and diastolic dysfunction following cardiopulmonary bypass in infants, despite preserved left ventricular function.
Pauliks et al. (2013) conducted an observational in Infants and neonates undergoing open heart surgery (n=53). Cardiopulmonary bypass surgery vs. Baseline (pre-operative) was evaluated on Myocardial velocities, isovolumic contraction acceleration (IVA), and peak strain rate (SR). Tissue Doppler imaging in 53 infants undergoing open heart surgery revealed significantly diminished right ventricular systolic and diastolic function post-cardiopulmonary bypass.
