A prominent Eustachian valve in the right atrium has been reported to
pose significant challenges during device closure of atrial septal
defects. We describe the procedural aspects of device closure in an ASD
with deficient rims and a redundant Eustachian valve. The prominent
Eustachian valve provided extra stability in the anteroinferior aspect
during device deployment and hence proved to be helpful for the
procedure. It is important to consider this aspect while planning device
closure
