Rotational ablation assisted angioplasty of an obstructed aortopulmonary collateral artery.

A 15 month old baby girl with pulmonary atresia, ventricular septal defect, and multiple aortopulmonary collateral arteries underwent rotational ablation assisted balloon angioplasty of a severely stenosed collateral artery that had previously proved undilatable using a high pressure non-compliant balloon angioplasty catheter. It is postulated that the rotablation debulked a fibrotic stricture within the artery to facilitate effective balloon dilatation. Rotational ablation assisted angioplasty may have a role to play in congenital stenotic lesions that are "undilatable".
