OBJECTIVE: To investigate the existing evidence for a link between maternal cardiac function, abnormal uteroplacental flow and poor perinatal outcome in women with and without known cardiac disease. METHODS: PubMed and EMBASE databases were searched systematically for studies relating cardiac functional parameters and uteroplacental Doppler flow with pregnancy outcome in women with pre-existing congenital cardiac disease and women without known cardiac disease. Only studies based on echocardiography were included. RESULTS: From 1732 citations, 10 articles were included. In women with known congenital heart disease, a relationship was found between abnormal uteroplacental Doppler flow patterns and cardiac function before and during pregnancy. Conversely, women without a history of congenital heart disease, but with abnormal uterine artery resistance and pregnancy complications, more often showed global left ventricular diastolic dysfunction (33%; P = 0.0001), impaired myocardial relaxation (72%; P < 0.0001) and left ventricular systolic dysfunction (17%; P = 0.006), even up to 1 year postpartum. CONCLUSION: There is increasing evidence for an association between pre-existing subclinical cardiac dysfunction, poor placentation (reflected by uteroplacental Doppler flow abnormalities) and poor pregnancy outcome. It may be postulated that pre-existing suboptimal cardiac performance, as a result of either congenital heart disease or a subclinical latent condition, is one of the common denominators of poor placentation, leading to poor pregnancy outcome.
