Why the study?
Inter-atrial shunt creation can increase cardiac output in severe PAH, but spontaneous defect closure can occur at long-term follow-up.

Inter-atrial shunt creation can increase cardiac output in severe PAH, but carries risks of arterial desaturation and spontaneous closure.
Pulmonary arterial hypertension (PAH) is a severe, progressive life-threatening condition. Inter-atrial shunt creation can lead to cardiac output increment at the expense of arterial blood desaturation At long-term follow-up, however, spontaneous defect closure can occur
