MRI - MRA of the chest
Coronal MRA
Axial MRA
Sagittal Gradient Echo
MRA of the chest performed one year prior illustrates a Fontan circulation
- the superior vena cava is connected to the right pulmonary artery (right-sided cavopulmonary anastomosis)
- the right-sided cavopulmonary anastomosis (SVC to RPA) allows a passive venous return to the pulmonary arteries
- the extraatrial conduit connects the IVC to both the right and left pulmonary arteries
- the extraatrial conduit allows flow from the IVC to both pulmonary arteries without the mechanical help of the right ventricle (bypassing the right ventricle)
- Blooming artifact within the LPA related to left pulmonary artery stent
