[Dyspnea and Right Heart Failure].

Dyspnea and Right Heart Failure Abstract. Acute right ventricular failure is a critical condition diagnosed by clinical presentation combined with echocardiography. Additional diagnostic tools including laboratory, ECG, right heart catheterization, and other imaging modalities are needed to confirm the diagnosis and determine the cause. The identification and treatment of the underlying pathology, the reduction of right ventricular afterload (if possible), optimization of preload (often diuretics, rarely volume), and hemodynamic support using vasopressors and/or inodilators are mainstays of treatment. In severe cases, special therapies and mechanical circulatory support come into play.
