[Treatment of cardiogenic shock due to right ventricular involvement].

The right ventricle is susceptible to changes in preload, afterload, and contractility. The answer is its dilation with dysfunction/acute failure; filling is limited to the left ventricle and cardiac output. Systemic venous congestion is retrograde to the right heart, it is involved in the genesis of cardiogenic shock due to right ventricle involvement. This form of shock is less well known than that which occurs due to left ventricular failure, therefore, treatment may differ. Once the primary treatment has been carried out, since no response is obtained, supportive treatment aimed at ventricular pathophysiology will be the next option. It is suggested to evaluate the preload for the reasoned indication of liquids, diuretics or even ultrafiltration. Restore or maintain heart rate and sinus rhythm, treat symptomatic bradycardia, arrhythmias that make patients unstable, use of temporary pacing or cardioversion procedures. Improving contractility and vasomotility, using vasopressors and inotropes, alone or in combination, the objective will be to improve right coronary perfusion pressure. Balance the effect of drugs and maneuvers on preload and/or afterload, such as mechanical ventilation, atrial septostomy and pulmonary vasodilators. And the increasing utility of mechanical support of the circulation that has become a useful tool to preserve/restore right heart function.
