Mortalité maternelle par mort subite. Résultats de l'enquête nationale française confidentielle sur la mortalité maternelle, 2010-2012

Sudden death is defined as unexpected cardiac arrest occurring less than one hour after the onset of the first symptoms. Between 2010 and 2012, 23 maternal deaths were considered as unexplained sudden deaths and three of them were not evaluated due to a lack of clinical data. In addition, 13 maternal deaths with an identified cause occurred in a clinical context of sudden death (7 cases of pulmonary embolism, 2 cases of epilepsy, and 2 cases of cardiomyopathy). The first maneuvers of resuscitation in the presence of bystanders were attempted in 8 of 22 cases (36%). This emphasizes the importance of teaching the non-medical resuscitation modalities of cardiac arrest in pregnant women. Pregnant women must receive accurate resuscitation as the whole population. An autopsy was performed in 10 of 33 cases (30%) and was considered incomplete in 3 patients. This result emphasizes the necessity to perform a systematic and specialized autopsy in the context of sudden maternal death, which is mostly unexplained.
