Peripartum Pulmonary Embolism

Pregnancy and peripartum increase the risk of venous thromboembolism (VTE) by many folds. Interestingly, the VTE is more common during the pregnancy, whereas the pulmonary embolism is more frequent in postpartum period. There are various risk factors for the VTE and pulmonary embolism in these patients. The important risks are improper thromboprophylaxis, obesity, and multigravida. The clinical parameters and the d-dimer are not used for diagnosis of thromboembolism during pregnancy and in the postpartum period. The compression ultrasonography (CUSG) is commonly used for VTE diagnosis; for the pulmonary embolism diagnosis, one has to consider the radiation hazard to the fetus as well as to the mothers. Ventilation/perfusion scan is the imaging of choice for patient who has respiratory signs with normal chest radiograph. If chest X-ray is abnormal with suspicion of peripartum pulmonary embolism (PPE), the choice should be computed tomographic angiography. Heparin and its derivatives remained the anticoagulation of choice for the treatment of VTE as well as the PPE, as it is a shorter acting, easy to reverse with protamine sulfate. Proper thromboprophylaxis is the key for prevention of VTE and peripartum pulmonary embolism

Peripartum Cardiomyopathy: Facts and Figures

Peripartum cardiomyopathy (PPCM) is a rare clinical entity during pregnancy. PPCM is a diagnosis of exclusion. These patients do not have prior history of heart disease, and there are no other known possible causes of heart failure. It is more common in African countries, may be related to the consumption of kanwa, in the postpartum period. The multiparity, African descent and pregnancy-induced hypertension are a few risk factors for PPCM. The exact etiology of PPCM is not known; possible theories range from myocarditis to the maladaptation to the changes of pregnancy. The clinical manifestation varies from shortness of breath to thromboembolic phenomenon. Echocardiography is essential for diagnosis as well as differential diagnosis of PPCM. These patients preferably are managed in tertiary healthcare facilities. Anticoagulation and antiarrhythmic medications are pillars for the management of PPCM patients. If required, mechanical devices should be used temporarily. PPCM patients may need heart transplant. The beneficial role of bromocriptine and immunosuppression is not clear in PPCM patients. Subsequent pregnancies should be avoided to prevent the PPCM occurrence
