# Left Pulmonary Artery Stenting for Left Pulmonary Artery Stenosis Following Patent Ductus Arteriosus Device Closure: Case Series and Review of the Literature

## TL;DR

This paper reports four cases where stenting was needed in the left pulmonary artery after device closure of a heart defect called patent ductus arteriosus.

## Contribution

The novelty lies in presenting a case series and literature review on a rare complication of PDA device closure requiring left pulmonary artery stenting.

## Key findings

- Four patients required left pulmonary artery stenting following PDA device closure.
- Device-related left pulmonary artery stenosis is a rare but recognized complication.
- Stent placement was effective in relieving the obstruction in these cases.

## Abstract

Percutaneous device occlusion is currently the standard of care for most cases of patent ductus arteriosus (PDA). Albeit infrequent, device-related left pulmonary artery (LPA) stenosis is a known complication of this procedure, occasionally requiring stent placement to relieve the obstruction. We present a series of four patients who required left pulmonary stenting after ductus arteriosus device closure. A review of the current evidence is presented.
