Peripartum cardiomyopathy: current state of knowledge, new developments and future directions.
Peripartum cardiomyopathy (PPCM) is a form of idiopathic dilated cardiomyopathy affecting women in late pregnancy or early puerperium. Although initially described in the late 1800s, it has only recently been recognized as a distinct cardiac condition. ⋯ In spite of significant improvements in understanding the pathophysiology and management of the PPCM many features of this unique disease are poorly understood, including incidence, etiology, epidemiology, pathophysiology, predictors of prognosis and optimal therapy. The present article revisits these concepts and recent advances in PPCM.

Acute ischemic stroke is a major cause of morbidity and mortality in developed countries. Intravenous thrombolysis with tissue plasminogen activator (tPA) within 4.5 hours of symptoms onset significantly improves clinical outcomes in patients with acute ischemic stroke. This narrow window for treatment leads to a small proportion of eligible patients to be treated. ⋯ New retrievable stent-based devices offer higher revascularization rates with shorter time to recanalization and are now generally preferred to first generation thrombectomy devices such as Merci Retriever or Penumbra System. These devices have been shown to be effective for opening up occluded vessels in the brain but its efficacy for improving outcomes in patients with acute stroke has not yet been demonstrated in a randomized clinical trial. We summarize the results of the major systemic thrombolytic trials and the latest trials employing different endovascular approaches to ischemic stroke.
