Tricuspid valve endocarditis caused by Group B streptococcus is a rare clinical entity with poor prognosis and has been previously reported following gynecologic procedures. ⋯ Group B streptococcus endocarditis is a serious complication of gynecologic procedures. The role of preoperative antibiotics, postoperative clinical suspicion of endocarditis based on respiratory symptoms and a multidisciplinary approach may lead to enhanced patient outcomes.

Pregnant women with venous thromboembolism are traditionally managed with anticoagulation, but inferior vena cava filters are an alternative. We balanced risks and benefits of an inferior vena cava filter in a decision analysis. ⋯ In view of their potential morbidity, inferior vena cava filters should be restricted to pregnant woman at strongly increased risk of recurrent venous thromboembolism.

Inherited bleeding disorders have the potential to cause bleeding complications during pregnancy, childbirth and the postpartum period as well as effect fetal outcomes. There is an evolving understanding of the need for specialised and individualised care for affected women during these times. The aim for each patient is to estimate the risk to mother, fetus and neonate; to implement measures to minimise these risks; and to anticipate complications and develop contingencies for these scenarios. ⋯ An understanding of the physiologic haemostatic changes associated with pregnancy as well as the scope of defects, inheritance and management of inherited bleeding disorders is paramount when caring for these women. Collaborative and prospective management in conjunction with haematology services underpins the approach advocated. This review draws on the available literature, and outlines the principles of care for women with inherited bleeding disorders before, during and after pregnancy, as well as their babies, based on both available data and collective clinical experience.

Case Reports
All that wheezes is not asthma: A cautionary case study of shortness of breath in pregnancy.
Shortness of breath is a common physiological pregnancy presentation, secondary to both hormonal and mechanical effects. Its pathological causes are common (asthma exacerbation or infection); new-onset cardiac pathology is rarely considered. ⋯ Peripartum cardiomyopathy affects 1 in 2500-4000 live births. Over 90% of women regain normal cardiac function postpartum with optimal medical management. Peripartum cardiomyopathy presents a diagnostic conundrum as its primary symptoms mimic not only those of normal pregnancy but also a number of other, more common conditions. It is important to consider cardiac causes of shortness of breath initially, and vital to revisit an initial non-cardiac shortness of breath diagnosis if there is no sustained improvement with treatment. In this case, asthma history and initial wheeze on examination impeded correct diagnosis; however, the situation was re-evaluated and correct diagnosis made when the patient's shortness of breath deteriorated. Subsequent multidisciplinary management and birth in an appropriate setting facilitated the best outcome for both mother and baby.

Respiratory failure affects up to 0.2% of pregnancies, more commonly in the postpartum period. Altered maternal respiratory physiology affects the assessment and management of these patients. Respiratory failure may result from pregnancy-specific conditions such as preeclampsia, amniotic fluid embolism or peripartum cardiomyopathy. ⋯ Chest wall compliance is reduced, perhaps permitting slightly higher airway pressures. Optimizing oxygenation is important, but data on the use of permissive hypercapnia are limited. Delivery of the fetus does not always improve maternal respiratory function, but should be considered if benefit to the fetus is anticipated.
