Final answer:
The rare cardiovascular disease that can occur during the last month of pregnancy or within the first six months after delivery is peripartum cardiomyopathy (PPCM), characterized by symptoms such as breathlessness, giddiness, and pallor of the skin. Hemolytic disease of the newborn is only a problem in second or subsequent pregnancies due to maternal sensitization to fetal blood cells during the first pregnancy.
Step-by-step explanation:
Rare Cardiovascular Disease in Pregnancy
The rare cardiovascular disease that occurs in the last month of pregnancy or the first six months after delivery is called peripartum cardiomyopathy (PPCM). It is a form of heart failure that can affect women of childbearing age. Symptoms may include breathlessness on exertion, giddiness, and pallor of the skin. In severe cases, it can lead to edema of the ankles. Peripartum cardiomyopathy is serious and requires immediate medical attention.
Why Hemolytic Disease Is a Concern in Subsequent Pregnancies
Hemolytic disease of the newborn becomes a problem during the second or subsequent pregnancies because the mother's immune system has become sensitized to the fetal red blood cells after the first pregnancy, leading to an immune response against the baby's blood cells in subsequent pregnancies
