Assessment of long-term cardiac adaptation in adult patients with type II atrial septal defect

ConclusionLong-term cardiac adaptation in ASD patients, with RV overfilling and LV underfilling, has a negative impact on systolic RV performance, a phenomenon which likely can be attributed to longitudinal dysfunction of the interventricular septum.Key Points• An LR shunt in type II ASD patients causes cardiac remodeling characterized by RV overfilling and conversely underfilling of the left ventricle.• At the long term, there is evidence of systolic dysfunction of the right ventricle in this group of patients.• Septal dysfunction underlies the observed impairment in RV function.
