[Acute right heart failure].

Even though, it has long been considered as a passive channel allowing communication between the systemic and pulmonary circulations, it is now clearly established that the right ventricle plays an essential role in cardio-pulmonary couple physiology. Its failure results in a clinical presentation that reflects the systemic congestion and reduced cardiac output. It is the consequence of two pathological situations frequently encountered in intensive care including pulmonary vascular resistance increase and right ventricle contraction alteration. Mechanical ventilation, certain drugs and volume overload can also participate. The management of the acute right heart failure is based on the combination of supportive treatment and causal treatment, specific to the etiology. Supportive therapy aims to optimize filling pressures, reduce afterload and support cardiac contractibility. With the growing number of therapeutic options used according to co-morbidities, decision-making by a multidisciplinary heart team seems essential.
