[Management of mitral valve stenosis during pregnancy at the Oran university hospital center: About 83 cases].

INTRODUCTION: The management of pregnancy in patients with mitral valve stenosis disease continues to pose a challenge to the clinician.

OBJECTIVE: The aim of study was to evaluate the association between mitral valve stenosis and maternal and fetal out come.

MATERIEL AND METHOD: Eighty-three pregnant women with mitral valve disease, followed-up from 2009 to 2012, were prospectively evaluated medical history, NYHA class assessment, ECG and echocardiography were performed during pregnancy and after delivery.

RESULTS: Women with mitral stenosis had significantly clinical higher incidence of complications deterioration of clinical status was observed (44.57%, P=0.0001) congestive heart failure had observed (27.71%, P=0.0001), hospitalization (33.73%, P=0.0001), need of cardiac medications (53.75%, P=0.009), arrhythmias (16%, P<0.05), New born outcome, mitral stenosis had an effect on fetal outcome. We had increasing preterm, delivery (17.50%, P=0.018), hypotrophy (20.48%, P=0.001), intra-uterine growth retardation (12.04%, P=0.011) new born hospitalizations (13.25%, P=0.03) Increased maternal morbidity and unfavorable fetal outcome was seen mostly in patients with moderate and severe mitral stenosis.

CONCLUSION: Pregnant with critical mitral stenosis form a high-risk groups of life-threatening complications. There is need for close maternal follow-up and fetal surveillance and repair of mitral stenosis should be performed before pregnancy.
