Abstract

Purpose of review

Heart disease is a leading cause of maternal death worldwide. In western countries, the principal causes of death from heart disease are myocardial infarction, cardiomyopathy and congenital heart disease, whereas in developing countries, rheumatic heart disease and its long-term consequences are more important.

Recent findings

There are few prospective studies upon which to base the management of these complex cases. However, best practice includes the assessment of women prepregnancy by a multidisciplinary team, with the aim of optimizing the clinical state, changing therapy to avoid teratogenic treatments and advising the patient and her relatives about the potential risks and possible complications that may arise. During pregnancy, the multidisciplinary team should define the level of care/surveillance required in each case. Some women may be safely looked after in a peripheral hospital, whereas others may need to be seen by the multidisciplinary team in the tertiary centre at regular intervals along with close echocardiographic monitoring.

Summary

The majority of women with preexisting heart disease can go through pregnancy safely, however, close attention to detail must be paid to avoid potential complications.
