Maternal mortality due to cardiovascular disease in France 2013-2015

Between 2013 and 2015, cardiovascular diseases became one of the two leading causes of maternal mortality, with 36 deaths (13.7% of maternal deaths). The overall maternal mortality ratio for cardiovascular diseases is 1.5 per 100,000 live births, stable compared to the 2010-2012 period. The etiologies in order of decreasing frequency are: pre-existing cardiomyopathies (n=10), aortic dissections (n=9), peripartum cardiomyopathies (n=6), myocardial infarction (n=4), valvular cardiopathies (n=4). Non-optimal care occurred in 72% of cases, increasing since the previous triennium (50%). Similarly, there is a significant increase in the proportion of preventable deaths (possibly or probably) from 35% to 66%. In women with known cardiovascular disease, the lack of multidisciplinary prepregnancy assessment and pregnancy follow-up is most frequent. In patients with unknown cardiovascular disease, the lack of diagnosis of a cardiac event is the most common failure. Cardiovascular conditions or cardiovascular risk factors should be investigated in early pregnancy in order to monitor and refer women to appropriate maternity hospitals. Recent dyspnea, worsening at the end of pregnancy and postpartum, should suggest a cardiac complication. In presence of chest pain, aortic dissection should be considered with the same degree of emergency as myocardial infarction or pulmonary embolism. Cardiac ultrasonography, chest CT, Nt-proBNP and troponin should be considered in case of chest pain or recent dyspnea. Women with cardiac symptoms should be referred to an emergency department (not necessarily to the local maternity) for a complete cardiovascular check-up.
