Dissection exposing the Lt. ventricle. There is incomplete closure of the ventricular septum (arrow) allows free communication and L to R shunt
Ventricular Septal Defect (VSD)
Heart ASD & VSD
A heart with both an ASD and a VSD. The heart is opened on the left side.The aortic arch at the top and pulmonary trunk below. A short thick ductus joins the aortic arch with the Lt. pulmonary artery. Any ductus arteriosus that is patent after the age of three months is abnormal.
Patent ductus arteriosus
Pulmonary trunk
Aortic arch
The area of coarctation is visible here as a segmental narrowing of the aorta (arrow). Such lesions typically present later in life than do preductal coarctations. Note the dilated ascending aorta and major branch vessels proximal to the coarctation. A large amount of blood reaches the lower extremities via dilated, tortuous collateral channels.
Coarctation of the aorta: postductal type
Coarctation of aorta postductal form
This portion of aorta was resected from a patient with a coarctation. The aorta narrows postductally here to about a 3 mm opening.The aorta is opened longitudinally here to reveal a coarctation.
