Transthoracic echocardiographic assessment of the right ventricle before and after caesarean delivery: A preliminary investigation.
Transthoracic echocardiographic evaluation of the right ventricle is more difficult than the left ventricle and has not been well characterised in the parturient during delivery. As a preliminary investigation, our goal was to use bedside transthoracic echocardiography to evaluate right ventricular myocardial function before and after caesarean delivery. Term parturients undergoing caesarean delivery under spinal anaesthesia were enrolled. ⋯ Elevation of brain natriuretic peptide (n=7) was associated with mildly decreased left ventricular strain, but creatine kinase-muscle/brain (n=4) was not associated with consistent changes in cardiac function. Further investigations into peripartum right ventricular function are required to validate the findings in this preliminary study. Findings of baseline mild right ventricular dysfunction and functional changes associated with troponin-T and brain natriuretic peptide warrant rigorous investigation.
