Valvular heart disease in pregnancy: maternal and fetal outcome.
The aim of this study was to evaluate the maternal and fetal outcome of pregnancy in Valvular Heart Disease (VHD). A better understanding of the effects of valvular abnormalities on pregnancy outcome is of value for risk assessment and the design of a therapeutic plan from the available information of a series of patient. A multicenter prospective study was carried out over a period of 5 years (2005-2009) involving 60 pregnant patients with valvular heart disease. Thirty eight patients (64%) had single valve involvement and mitral stenosis was the most predominant lesion (50%). Ten patients (16.7%) had undergone interventional and surgical correction prior to the pregnancy. Fourteen (24%) patients were identified as a NYHA class III-IV. Women with VHD had 8.35% pulmonary edema, 15.03% developed different types arrhythmia. The incidence of preterm birth and small for gestational age newborn was 11.69% and 13.36% respectively. There was one (1.67%) maternal death. Pregnancy in women with valvular heart disease is associated with remarkable unfavourable effect on maternal and fetal outcome which are related to severity of disease.
