“…4 A second technique involves expansion of one stent in the distal main pulmonary artery (MPA) over one or two balloons with guidewires positioned in each distal branch pulmonary artery (“double-wire” technique). 5, 6 A more recently described strategy involves expansion of one stent from the distal MPA to a proximal stenotic branch pulmonary artery thereby jailing the other branch pulmonary artery, and then subsequently dilating the jailed vessel with a balloon advanced through the struts of the stent. 7, 8 While each of these strategies may be useful, none address bilateral branch pulmonary artery stenoses while also permitting subsequent placement of a transcatheter valve.…”

Balloon angioplasty and stent placement in close proximity to the bifurcation of the branch pulmonary arteries can be challenging. Multiple approaches have been previously described, though none of these approaches both treats bilateral proximal branch pulmonary artery stenosis and provides an anchor for a transcatheter pulmonary valve replacement. We report a novel approach that involves serial stent placement and balloon dilation through the struts of the stent in each pulmonary artery, along with balloon expansion of the proximal portion of the stents to the diameter of the main pulmonary artery. In the two cases we describe, this strategy resulted in significant relief of branch pulmonary artery obstruction without compromising the anatomy of the main pulmonary artery segment. This technique can be an effective way to alleviate stenoses of the bilateral proximal branch pulmonary arteries and provide a landing zone for a future transcatheter pulmonary valve.
