The author states that anticoagulation management is complex in women with mechanical values. Pregnancy induces a prothrombotic state, which increases the risk of mechanical valve thrombosis and makes it difficult to maintain stable anticoagulation.
Correct answer: A. A low risk of maternal mortality and a moderate risk of morbidity
There are four WHO Pregnancy categories: I = no significant maternal morbidity or mortality. II = a low risk of maternal mortality and a moderate risk of morbidity. III = a high risk of complications with a significantly increased risk of maternal mortality or morbidity. IV = a very high risk of maternal mortality or morbidity that contraindicates pregnancy.
Correct answer: C. 24.5%
A validation study comparing risk models for pregnancy complications in women with CHD found a risk of cardiovascular complications of 0% for WHO Class I, 6.8% for WHO Class II, 24.5% for WHO Class III, and 100% for WHO Class IV.
Correct answer: A. True
