Key result
PDA delivery sheath stabilizes balloon slippage during valvuloplasty for severe dysplastic pulmonary valve restenosis.
Why the study?
Balloon pulmonary valvuloplasty in dysplastic pulmonary valve restenosis remains challenging due to difficulty stabilizing the balloon at the valve level.
Does using a PDA device delivery sheath allow for successful balloon pulmonary valvuloplasty in patients with severe dysplastic pulmonary valve restenosis and balloon instability?

Does using a PDA device delivery sheath allow for successful balloon pulmonary valvuloplasty in patients with severe dysplastic pulmonary valve restenosis and balloon instability?
A PDA device delivery sheath can be used as a novel technique to stabilize the balloon during balloon pulmonary valvuloplasty in challenging cases of dysplastic pulmonary valve restenosis.

Balloon instability may thwart BPV in dysplastic PV restenosis; leaves open need for specialized devices or alternatives in refractory cases.
Balloon pulmonary valvuloplasty (BPV) is an interventional procedure that has practically replaced the need of open-heart surgery in patients with severe valvular pulmonary stenosis. However, BPV in dysplastic pulmonary valve (PV) still remains a challenge in the current milieu of advanced technologies. We encountered a unique situation of severe restenosis of PV wherein the attempt to balloon dilate the valve was futile because no balloon remained stable at the level of the valve. This situation was overcome using a PDA device delivery sheath to keep the balloon positioned at the desired location.

Rajan et al. (2020) conducted a case report in Severe dysplastic pulmonary valve restenosis (n=1). Balloon pulmonary valvuloplasty using a PDA device delivery sheath was evaluated on Successful balloon stabilization and dilation. Balloon instability during pulmonary valvuloplasty for severe dysplastic pulmonary valve restenosis was successfully overcome by using a PDA device delivery sheath to keep the balloon positioned.
