[Cardiac insufficiency: acute right heart failure].

Acute right heart failure (RHF) is a frequent and severe complication during perioperative and intensive care treatment in intensive care units (ICUs). The most common causes are pulmonary hypertension, left heart failure, pulmonary embolism, sepsis, acute lung injury (ALI) and thoracosurgical procedures. Acute RHF is not only a major contributor to morbidity and mortality; it also influences efficacy and outcome of routinely performed procedures, such as vasopressors, in critically ill patients. In contrast to the left ventricle, the right ventricle's physiology and pathophysiology are understudied, and the diagnosis of acute RHF is frequently challenging. Although many drugs are available for the treatment of RHF, randomized trials for this setting are still missing. This article gives an overview of aetiology and pathogenesis of RHF and reviews the diagnostic and therapeutic interventions currently available for providers in anaesthesiology and critical care.
