When presented with the options, women may make very different decisions. Some women in fact may decide to assume a small risk of oral cleft over a 0.05% risk for a heart malformation because they feel that oral clefts can be repaired more easily, while the morbidity and mortality of Ebstein's anomaly is high, even though the risk is exceedingly small. That is why these decisions have to be made individually, because such decisions will be made not based on relative risk or even absolute risk but rather on each patient's perception of risk.
