Conclusion
Atrial septal defects are the most common congenital heart defect to present in adulthood and sinus venosus subtype represents 2-10% of all of ASDs.
Sinus venosus ASD (SVASD) is associated with partial anomalous pulmonary venos return.
A left-to-right shunt can be present,
which may lead to right ventricular volume overload,
development of elevated right ventricular pressures and possible subsequent development of irreversible pulmonary hypertension.
Surgical repair of of SVASD is usually indicated,
with survival rates similar to those expected for age and gender matched controlled populations.
CTA and CMR are excellent noninvasive imaging techniques which allow accurate identification of cardiac anatomy.
CMR has the added value of assessment of flow measurements and function,
with calculation of Qp:Qs,
providing the surgeon with a superb road-map and ability for morphologic assessment,
further facilitating a favorable operative outcome.
