Detection of right ventricular insufficiency and guidance of volume therapy are facilitated by simultaneous monitoring of static and functional preload parameters.
Acute right ventricular failure (RVF) is a life-threatening condition. This study investigated whether the combination of central venous pressure (CVP) and left ventricular functional preload parameters, such as stroke volume variation (SVV) and pulse pressure variation (PPV), can be used for the detection of acute RVF and for guidance of volume therapy. ⋯ Increases of CVP and SVV or PPV are suspicious for RVF. However, SVV and PPV fail to predict volume responsiveness in RVF. Changes in SVV and PPV during a volume-loading maneuver can be used to assess volume responsiveness.

Review Meta AnalysisEndovascular stenting or carotid endarterectomy for treatment of carotid stenosis: a meta-analysis.
To compare carotid artery stenting with open carotid surgery for the treatment of symptomatic or asymptomatic carotid artery stenosis in terms of stroke, myocardial infarction, and death at 30 days. ⋯ Compared with stenting, carotid endarterectomy decreases the risk of stroke at 30 days, increases the risk of myocardial infarction, and does not affect the risk of death.
