Figure 1. Transoesophageal echocardiographic anatomical assessment of patent foramen ovale (PFO).
Baseline TEE anatomical assessment in multiple 2D views showing favourable septal overlap in the bicaval view (A) that reduces to 4 mm in the short-axis view (B), baseline colour left-to-right shunt (stretched PFO) in both views (C & D), microbubble passage at rest even before the complete filling of the right atrium (E) and wide PFO opening with severe right-to-left shunt during Valsalva manoeuvre (F). Sizing balloon interrogation of the atrial septum demonstrating minimum overlap between septum secundum (SS) and septum primum (SP) (G). Percutaneous PFO closure using the NobleStitch device: delivery of septum secundum (H) and septum primum (I) sutures. Follow-up TEE evaluation at three months showing the KwiKnot (asterisk) in place (J & K) and demonstrating incomplete closure of the PFO with residual left-to-right colour shunt (L & M) and residual right-to-left shunt during Valsalva manoeuvre (N & O).
