Case Reports[Large ostium secundum atrial septal defect discovered after severe mitral regurgitation. A case report].
Mitral regurgitation is associated with ostium secundum atrial septal defect in about 22% of cases. mitral valve prolapse induced by atrial shunt is the main cause of this regurgitation. Ususually, atrial septal defect discovery precedes that of mitral regurgitation. The aim of this paper is to focus on clinical, hemodynamic and evolutive details of atrial septal defect and mitral regurgitation association. We report the case of large atrial septal defect in 37 years old girl referred for hemodynamic investigation of mitral regurgitation. The divergence of clinical data, electrocardiogram and echocardiography findings has led to atrial septal defect discovery. Hemodynamic data showed severe pulmonary arterial hypertension (medium pulmonary arterial pressure: 45 mmhg). Hence, mitral valve substitution by mechanical prosthesis and closure of atrial septal defect have been carried out. Ten hours after surgery, death occurred because of severe pulmonary arterial hypertension and heart failure. ⋯ Association of severe mitral regurgitation and large ostium secundum atrial septal defect is an original anatomo-clinic entity caracterized by mitral valve lesions diversity and severe secondary pulmonary arterial hypertension. Danger of such a hypertension is due to progressive and infra clinical rise of pulmonary resistances and association of increased pulmonary blood flow and capillary pulmonary hypertension.

The delivery haemorrhage is actually a problem of public health. It is responsible of 31.5 % of the maternal death in Tunisia. The goal of this work is to study the frequency of this complication, its gravity, its risk factors, its etiologists and its methods of treatment. ⋯ Factors of risk taking out again our set are: gestational toxemia (35.4%), primiparity (33.8%), advanced maternal age (30.7%), pre-existent anaemia (24.6%). the uterine surdistension (21.3%), an abnormal middle length of labour (69.6%). use of oxytocin during labour (34%), induction (21.5%). Etiologists in our set are: atone in 63% of cases, retained placenta in 31.2% des cases, coagulopathie (9.2%), placenta previa (1.5%), uterine inversion (1.5%). The hold must be in charge multidisciplinary, systematized, precocious and dynamic.
