Our aim is to determine the effect of mitral valvular disease on pregnancy follow up parameters and newborns.

Material and Methods:

We retrospectively reviewed the pregnant patients those were hospitalized because of mild-moderate mitral valve stenosis (n=16) between January 1998 and January 2011 in our center. Echocardiography was performed with regular intervals and the datas were recorded. Gestational age of delivery, type of delivery, general condition of newborn due to APGAR system were assessed. Values were compared with those of controls without any cardiac disease (n=16).


Mean mitral valve area, average mitral gradient and systemic pulmonary artery pressure were established 1.44+0.45 cm2, 5.2+1.5 mmHg ve 23+4.8 mmHg respectively in patients with mitral stenosis. Mean gestational age of delivery was 36.2±1.4 weeks (p=0.001) and mean fetal weight was 2646±431.1 g (p=0.016) in patients with mitral valve stenosis. These values were 38.7±2.12 weeks and 3056±212.13 gram respectively in control group. No significant difference was observed in terms of 1. and 5. APGAR scoring system among two groups.


To optimize pregnancy outcomes, accurate diagnosis of the etiology, severity of valve disease and preconception evaluation are the main factors. Obstetrician should be careful in terms of intrauterine growth retardation and preterm delivery during pregnancy in patients with mitral valve stenosis.
