NameTimeMethod
<p>• Assessment of the device shape and relation to adjacent atrial/ aortic walls;<br /><br>o Device size, device/defect ratio, device/ septal ratio<br /><br>o Aortic-end shape (flare vs. closed)<br /><br>o Relation to adjacent structures (aorta/atria): non-touch, touch or pressure<br /><br><br /><br>• Retrospective assessment of periprocedural echocardiography before device<br /><br>deployment;<br /><br>o Total septal length(s)/area (3D)<br /><br>o Septal mobility (redundancy)<br /><br>o Septal eccentricity/mal-alignment<br /><br>o Defect size and shape (3D)<br /><br>o Defect expansibility (dynamicity)<br /><br>o Adequacy and consistency of rims<br /><br><br /><br>• Retrospective assessment of periprocedural echocardiography before and after<br /><br>device deployment;<br /><br>o Aortic annular diameters (AP, ML) and eccentricity (systolic and diastolic)<br /><br>o SOV diameters (AP, ML) and eccentricity (systolic and diastolic)<br /><br>o STJ diameters (AP, ML) (systolic and diastolic)</p><br>
Secondary Outcome Measures
NameTimeMethod
