Mitral stenosis is a risk factor for maternal and fetal complications during pregnancy. We aimed to evaluate the fetal and maternal complications of 15 consecutive patients referred for treatment in our tertiary care antenatal cardiology clinic from 2009 to 2014. Their baseline characteristics are described on table 1.
Of the 18 pregnancies reported, 5 women presented with pulmonary edema without a previous clinical diagnosis. Clinical deterioration of 1 or more NYHA FC occurred in another 10 pregnancies. Four patients needed hospitalization due to cardiac decompensation. All patients received beta blockers, 12 diuretics and 1 anticoagulants. Six patients were referred for percutaneous mitral valvuloplasty - one during pregnancy, and 5 postpartum. Four of them had additional 5 pregnancies with no cardiac events.Mean gestational age at delivery was 36.6±0.7 weeks (range 25-39). Nine patients underwent cesarean section, 4 for obstetric and 5 due to cardiac reasons. There was one case of postpartum pulmonary edema and one case of amnionitis. Mean birth weight was 2587±347 grams, 3 neonates were small for gestational age and 4 weighed less than 2500 grams at birth.Conclusion: Despite unfavorable presentation strict follow-up and meticulous care can lead to a favorable outcome in pregnant women with mitral stenosis
