Rethinking paracorporeal lung assist device support in the modern era: Why so different than ECMO?

Area of Science:

• Pediatric Cardiology
• Cardiopulmonary Support
• Transplant Surgery

Background:

• Pediatric patients with combined pulmonary disease and right ventricular (RV) failure face challenges with rehabilitation and transplant candidacy.
• Conventional extracorporeal membrane oxygenation (ECMO) presents limitations in these complex cases.
• A novel paracorporeal lung assist device (PLAD) configuration is explored as a bridge to lung transplantation.

Purpose of the Study:

• To evaluate the efficacy of a novel PLAD configuration in pediatric patients with combined pulmonary and RV failure.
• To assess the PLAD as a bridge to lung transplantation.
• To determine the impact on patient rehabilitation and transplant outcomes.

Main Methods:

• Three pediatric patients with refractory pulmonary hypertension and RV failure were supported with PLAD.
• The PLAD configuration included an inline pump, left atrial appendage cannulation, and main pulmonary artery cannulation.
• Patients underwent comprehensive clinical and rehabilitative assessments.

Main Results:

• All patients showed significant clinical improvement on PLAD support.
• Pulmonary artery pressures decreased, and RV function improved.
• Patients achieved successful physical and nutritional rehabilitation, including ambulation, and all underwent successful bilateral lung transplantation.

Conclusions:

• PLAD with inline pump support is an effective bridge to lung transplantation for pediatric patients with combined pulmonary and RV failure.
• This configuration facilitates cardiac and physical rehabilitation while reducing pulmonary artery pressures.
• The PLAD approach may expand transplant candidacy and improve long-term outcomes.
