Question 7

Risk of recurrence of peripartum cardiomyopathy

Answer 7

If recovered - 20% in subsequent pregnancy
If not recovered - high risk of recurrence/mortality

Question 8

Answer 8

20% - significant decline, require transplant
30-50% - partial recovery
30-50% - significant improvement

Question 9

Recurrent - 3%
