Pulmonary hypertension, a condition that can lead to right ventricular failure and hemodynamic collapse, can be very challenging to manage in critically ill patients who require the intensive care unit. Because of the underlying structure of the right ventricle, significant increases in right ventricular afterload initiate a vicious cycle of degenerating right ventricular function, giving rise to right ventricular failure and cardiogenic shock. In patients with pulmonary hypertension, inciting factors such as sepsis and arrhythmias can exacerbate this process...

Despite advances in medical therapies, pulmonary arterial hypertension (PAH) continues to cause significant morbidity and mortality. Although the right ventricle (RV) can adapt to an increase in afterload, progression of the pulmonary vasculopathy that characterizes PAH causes many patients to develop progressive right ventricular failure. Furthermore, acute right ventricular decompensation may develop from disorders that lead to either an acute increase in cardiac demand, such as sepsis, or to an increase in ventricular afterload, including interruptions in medical therapy, arrhythmia, or pulmonary embolism...

Acute right ventricular (RV) failure is a frequent and serious clinical challenge in the intensive care unit. It is usually seen as a consequence of left ventricular failure, pulmonary embolism, pulmonary hypertension, sepsis, acute lung injury or after cardiothoracic surgery. The presence of acute RV failure not only carries substantial morbidity and mortality, but also complicates the use of commonly used treatment strategies in critically ill patients. In contrast to the left ventricle, the RV remains relatively understudied, and investigations of the treatment of isolated RV failure are rare and usually limited to nonrandomized observations...

PURPOSE OF REVIEW: This review summarizes the approach to and recent developments in the evaluation and treatment of acute right heart failure in the ICU. Right heart failure, defined as failure of the right ventricle to provide sufficient blood flow through the pulmonary circulation at normal central venous pressure, is a common problem caused by a combination of increased right-ventricular afterload and right-ventricular contractile dysfunction. RECENT FINDINGS: Management of acute right heart failure continues to be challenging because of insufficient understanding of its pathophysiology, a lack of guidelines, and few available tools...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
