1–10 Although stents have a number of advantages and are useful in a variety of circumstances, there are also potential limitations and drawbacks to stenting. Since their first use in patients with congenital heart disease nearly 20 years ago, balloon-expandable intravascular stents have become indispensable tools in the management of essentially all forms of large vessel obstruction.

There were no vascular or other complications.Ĭonclusions- UHP angioplasty was safe and effective for treatment of stent-related resistant PA stenosis in this series the ability to fracture maximally expanded stents may extend the utility of stents in the pediatric population. In 5 lesions, UHP angioplasty fractured the stent, allowing further vessel expansion. After UHP dilation, lesion diameter increased by a median of 3.1 mm (36%), significantly more than after previous high-pressure dilation (1.3 mm, 19% P<0.001).

Balloon:waist diameter ratios were conservative (median 1.26), reflecting the ability of UHP balloons to “fracture” nearly all obstructions. Thirty-one of the 34 (91% ) UHP angioplasty procedures were successful in relieving the resistant stenosis. The median age at UHP angioplasty was 9 years, and a median of 4 years had elapsed since unsuccessful high-pressure angioplasty. Thirty-four lesions in 29 patients, including 8 with multiple concentric, overlapping, or adjacent stents, were included. A resistant stenosis was defined as a residual balloon waist during high-pressure redilation of the stent, along with a pressure gradient and/or angiographic stenosis. Methods and Results- We reviewed patients who underwent UHP angioplasty of in-stent or peri-stent PA stenoses that were resistant to high-pressure redilation. Angioplasty with ultra-high-pressure (UHP) balloons may facilitate successful treatment of stent-associated PA stenoses that are resistant to high-pressure dilation. Although stents can usually be reexpanded as children grow, resistant in-stent or peri-stent obstruction can complicate the management of PA stents.
