Treatment of Atrial Septal Defect with Pulmonary Vascular Resistance 3–5 WU and Significant Left-to-Right Shunt

This protocol applies to patients with atrial septal defect presenting with an intermediate elevation in pulmonary vascular resistance alongside a haemodynamically significant left-to-right shunt.

In this specific haemodynamic context, a structural intervention directed at the septal defect itself is the approach outlined in the evidence-based protocol. The full regimen — including procedural criteria, sequencing, and case-specific considerations — is available via the link below.
