Right Ventricle in ARDS

Prone positioning unloads the right ventricle in severe ARDS.

BACKGROUND Despite airway pressure limitation, acute cor pulmonale persists in a minority of ARDS patients. Insufficient airway pressure limitation, hypercapnia, or both may be responsible. Because prone positioning (PP) has been shown to be a safe way to reduce airway pressure and to improve alveolar ventilation, we decided to assess its effect on right ventricular (RV) pressure overload in AR...

Rationale and Description of Right Ventricle-Protective Ventilation in ARDS.

Pulmonary vascular dysfunction is associated with ARDS and leads to increased right-ventricular afterload and eventually right-ventricular failure, also called acute cor pulmonale. Interest in acute cor pulmonale and its negative impact on outcome in patients with ARDS has grown in recent years. Right-ventricular function in these patients should be closely monitored, and this is helped by the ...

Acute cor pulmonale in ARDS: rationale for protecting the right ventricle.

The ventilatory strategy for ARDS has been regularly amended over the last 40 years as knowledge of the pathophysiology of ARDS has increased. Initially focused mainly on the lung with the objectives of "opening the lung" and optimizing arterial oxygen saturation, this strategy now also takes into account pulmonary vascular injury and its effects on the right ventricle and on hemodynamics. Hemo...

Clinical manifestations of right ventricle involvement in inferior myocardial infarction

Abstract Background: Early diagnosis of right ventricle (RV) involvement in inferior myocardial infarction (Inf MI) is very critical. This study was performed to evaluate the clinical findings of Inf MI with or without RV infarction. Methods: From September 2010 to September 2012, 195 patients with definite diagnosis of Inf MI were evaluated in the Department of Cardiology, in Babol, north of...
