Non-invasive cardiac output monitoring for cesarean delivery under epidural anesthesia in a patient with Marfan syndrome and cardiomyopathy.

•Cardiomyopathy can predispose parturients to acute heart failure at delivery.•Non-invasive cardiac output monitoring may be useful for high-risk parturients.•Hypovolemia and slow oxytocin administration may delay increases in cardiac output at delivery.•In our case, mean arterial pressure and heart rate did not correlate with cardiac output trends.
