Right heart failure

Right heart failure is mainly manifested by the syndrome of systemic circulation congestion. Right heart failure is mainly right ventricular dysfunction, which is seen in pulmonary heart disease, tricuspid valve, or pulmonary valve disease, and often secondary to left heart failure. At this time, cardiac output is reduced, systemic circulation is congested, and venous pressure is increased, often accompanied by lower limb edema, and systemic edema may occur in severe cases.
