Mitral valvotomy during pregnancy.

Mitral valve surgery and maternal and fetal outcome in valvular heart disease

Background
Valvular heart disease constitutes the majority of all causes of heart disease in pregnancy. In the presence of valvular heart disease, the necessary haemodynamic changes of pregnancy might cause heart failure, leading to severe maternal and fetal morbidity and even mortality. Treatment of valvular heart disease is indicated when patients experience a deterioration of symptoms and in case of a severe valvular lesion. Whether medical therapy or interventional therapy is the optimal treatment for both mother and child is unclear.

Objectives
To assess effectiveness and adverse effects of the different treatment modalities of valvular heart disease in pregnancy to improve maternal and neonatal outcomes.

Search methods
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 March 2011), EMBASE (1980 to 23 March 2011) and the reference lists of background review articles.

Selection criteria
Randomised controlled trials, quasi-randomised controlled and cluster-randomised controlled trials comparing medical therapy with percutaneous or surgical intervention for the treatment of valvular heart disease in pregnancy.

Data collection and analysis
We identified no (randomised) controlled trials to assess the effectiveness and adverse effects of the treatment of valvular heart disease in pregnancy.

Main results
There were no randomised controlled trials, quasi-randomised controlled trials or cluster-randomised trials identified from the search strategy.

Authors' conclusions
There is insufficient evidence to define the most effective treatment of valvular heart disease in pregnancy to improve maternal and neonatal outcomes.
