How does nonpulsatile maternal cardiopulmonary bypass affect fetal and uterine hemodynamics during pregnancy?
Nonpulsatile cardiopulmonary bypass during pregnancy may fail to meet fetoplacental circulatory demands, leading to severe fetal morbidity despite maintaining normal maternal hemodynamics.
Khandelwal et al. (1996) conducted a case report in Severe aortic regurgitation in pregnancy (n=1). Maternal cardiopulmonary bypass vs. Normal reference values was evaluated on Fetal and uterine hemodynamics and fetal outcome. Maternal nonpulsatile cardiopulmonary bypass during aortic valve replacement resulted in severe fetal hemodynamic deterioration, including bradycardia and hydrops, leading to a dismal fetal outcome.
