Why the study?
Restrictive physiology among children undergoing percutaneous ASD closure is unexpected and has not been previously described in the literature.
Left ventricular diastolic dysfunction can unexpectedly occur in children undergoing ASD closure and can be successfully managed with pharmacological preconditioning.
Atrial septal defect (ASD) associated with left ventricular (LV) diastolic dysfunction (DD) is rare in children. DD is common in elderly patients undergoing ASD closure. Restrictive physiology among children undergoing percutaneous ASD closure is something unexpected that has not been described before in the literature. Hence, we report a child referred to our center for ASD closure in whom an LV DD has been unmasked with a balloon occlusion test and has been managed with pharmacological preconditioning and subsequent ASD closure with good outcome. Albeit rare, LV DD can occur in children undergoing ASD closure.
