Sinus Venosus Atrial Septal Defect - Magnetic Resonance Imaging

Sinus venosus atrial septal defects (SV-ASDs) are inter-atrial communications caused by a deficiency of the common wall between the superior or inferior vena cava and the right-sided pulmonary veins.

MRI from a 25-year-old asymptomatic male.

• a - Breath-held fat suppressed three-dimensional steady-state free precession (SSFP) pulse sequence in diastole in the sagittal view demonstrating sinus venosus atrial septal defect (SV-ASD) (arrow) between superior vena cava (SVC) and left atrium (LA).
• b - Breath-held fat suppressed three-dimensional SSFP pulse sequence in diastole in the axial view demonstrating SV-ASD (arrow) between SVC and LA.
• c - Turbo spin-echo black blood image in the same axial plane as ure 1b demonstrating SV-ASD (arrow) between SVC and LA.
• d - SSFP image showing the dilated right ventricle (RV) and left ventricle (LV)
