Figure 2: Atrial septal stenting in univentricular heart with mitral stenosis. During septal puncture (a), the needle tip pierces the left atrial (LA) roof and contrast stains the pericardial cavity shown by multiple arrows. The needle is withdrawn minimally (b) and a coronary floppy guidewire (dotted arrows) is advanced to coil in the left atrium. After exchanging to a stiff guidewire, a stent is partially unsheathed across the atrial septum (c) with check injections from the sheath tip into the right atrium (RA). Finally, stent is deployed (d) with a dog-bone configuration
