Implication

May support ASD closure for hypoxaemia from paradoxical shunt in select cases; leaves open need for prospective validation.

Key Points

To evaluate the impact of secundum atrial septal defect on hypoxaemia and its successful closure.
Diagnosed secundum atrial septal defect via transthoracic and transoesophageal echocardiography.
Measured atrial pressures using cardiac catheterization before intervention.
Performed percutaneous closure using an Amplatzer septal occluder.
Hypoxaemia resolved immediately following septal closure procedure.
Eight months post-procedure, echocardiography showed no shunting at atrial level.
Identified impaired reservoir function of the right atrium due to pressure overload.

Structured PICO

Population

1 49-year-old woman with dyspnoea, history of surgical dilatation of stenotic pulmonary valve at age 10, presenting with hypoxaemia due to a right-to-left shunt through a secundum atrial septal defect.

Intervention

Percutaneous closure using an Amplatzer septal occluder

Outcome

Resolution of hypoxaemia and absence of shunting

Percutaneous closure of a secundum ASD can successfully resolve hypoxaemia caused by a paradoxical right-to-left shunt in a patient with a pressure-overloaded right ventricle.
