Дефект міжшлуночкової перегородки

Pulmonary blood flow and LA and LV volumes are increased. Atrial pressures are mean pressures. RV pressure and O₂ saturation are variably elevated, positively related to defect size.

AO = aorta; IVC = inferior vena cava; LA = left atrium; LV = left ventricle; PA = pulmonary artery; PV = pulmonary veins; RA = right atrium; RV = right ventricle; SVC = superior vena cava.
