Hello and welcome to the Zero to Finals podcast.

My name is Tom and in this episode I'm going to be talking to you about Eisenmengar Syndrome.

And if you want to follow along with written notes on this topic,

you can follow along at zero definals.com slash isomengar syndrome

or in the cardiology section of the Zero to Finals Pediatrics book.

So let's get straight into it.

Isamanga syndrome occurs when blood can flow from the right side of the heart to the left side

of the heart across a structural heart lesion.

When blood flows from the right side to the left side of the heart, it bypasses the

lungs, allowing deoxygenated blood to flow into the systemic circulation. There are three

underlying lesions that can result in isomenga syndrome, and these are atroceptal defect,

ventricular septal defect, and patent ductus arteriosis.

Isamanga syndrome can develop after one to two years with large defects in the heart

or in adulthood when there's a small defect.

It can develop more quickly during pregnancy, so women with a history of having a hole in the heart

need to have an echocardiogram

and need to be closely monitored by a cardiologist during pregnancy. It's worth being very familiar

and understanding the pathophysiology of Eisenmenga syndrome. Normally when there's a septal defect

between the two sides of the heart, whether this is an atrial septal defect or a's a septal defect between the two sides of the heart,

whether this is an atrial septal defect or a ventricular septal defect,

or even a patent ductus arteriosis,

blood will flow from the left side of the heart to the right.
