Outcomes associated with balloon angioplasty for recurrent coarctation in neonatal univentricular and biventricular norwood‐type aortic arch reconstructions

Abstract

Recurrent coarctation following NTAR is more common in 2V patients than in SV patients. BA for recurrent coarctation has similar success in both groups and should continue to be utilized in this population.

Acute and mid‐term outcomes of stent implantation for recurrent coarctation of the aorta between the Norwood operation and fontan completion: A multi‐center Pediatric Interventional Cardiology Early Career Society Investigation

“…Factors associated with higher rates of RC after BA included smaller patients and older age at the time of Norwood procedure [16]. In our study, 88% of patients who ultimately underwent SI for RC had previously undergone BA, which is consistent with estimates from prior studies that 15–20% of patients would be nonresponders to BA . This also suggested BA being the first line treatment of RC for most operators and SI would be considered if unsatisfactory BA results.…”

“…Although typically attempted first, BA to treat RC is not uniformly acutely successful and often does not provide durable gradient relief. Studies have suggested a high success rate of BA but variable freedom of re‐intervention . Factors found to contribute to successful BA were larger balloon size, lower initial peak‐to‐peak gradient and larger diameter of descending aorta in one study .…”

“…Transcatheter treatment of RC in SV patients using balloon angioplasty (BA) has been well described . While BA is generally considered the first‐line treatment for SV patients with RC, BA may result in inadequate acute relief of aortic obstruction, nondurable relief of obstruction (e.g., early recurrence), or both .…”

Recurrent Coarctation After Neonatal Univentricular and Biventricular Norwood-Type Arch Reconstruction

“…We recently described the outcomes of transcatheter intervention for recurrent coarctation in this population [18]. The aims of this study were to describe the surgical outcomes and risk factors for recurrent coarctation after NTAR in patients with SV and those with 2V anatomy.…”
