# Innovative Use of Coronary GuideLiner to Facilitate Patent Ductus Arteriosus Stent Reintervention

## TL;DR

This paper introduces a new technique using a coronary GuideLiner to help with stent reintervention in patent ductus arteriosus in two young patients with heart disease.

## Contribution

The first reported use of a coronary GuideLiner to facilitate PDA stent reintervention in complex pediatric cases.

## Key findings

- The GuideLiner successfully enabled stent crossing and restenting in two infants with complex heart disease.
- This technique overcame historical challenges in PDA stent reintervention.
- The approach proved effective for patients requiring repeated interventions on previously placed stents.

## Abstract

This is the first report using a coronary GuideLiner (Teleflex) to overcome the challenge of patent ductus arteriosus (PDA) stent crossing and restenting. We present 2 patients, a 3-month-old and a 15-month-old, with complex cyanotic heart disease and ductal-dependent pulmonary blood flow who previously underwent PDA stenting and required reintervention on the PDA stent. Historically, patients who require reintervention for PDA stenting have been challenging, especially when restenting is needed. The use of the GuideLiner was a game-changer in these 2 cases.
