What is the problem of cardiac RV?
The lack of popular autism is that the residual pores of the atria during embryonic separation are not closed. The common type is probably the primary pore defect, and the secondary pore type is also called the central hole type and the upper cavity type and the lower cavity type. The pathophysiological changes are mainly a hole in the atrial septum that produces a left-to-right shunt at the atrial level, which increases the blood flow in the pulmonary circulation and dilates the right heart system and pulmonary artery. Pulmonary arterial hypertension can occur when there is a large absence of housing or without early treatment, and some patients will lose the opportunity for surgical treatment.
