Final answer:
A heart transplant is not an absolute contraindication for pregnancy if the recipient is stable and the transplant was successful with good graft function, unlike Eisenmenger syndrome and peripartum cardiomyopathy, which are usually contraindications.
Step-by-step explanation:
The question asks which heart condition is not a contraindication for pregnancy. Out of the options given, a heart transplant is generally not considered an absolute contraindication for pregnancy if the woman is stable and the transplant was successful with good graft function. However, special considerations and close monitoring would be necessary. In contrast, Eisenmenger syndrome and peripartum cardiomyopathy are usually considered contraindications to pregnancy due to the significant risks they pose to both the mother and fetus.
