Transcatheter Pulmonary Valve Replacement With Balloon-Expandable Valves: Utilization and Procedural Outcomes From the IMPACT Registry

JACC Cardiovasc Interv. 2024 Jan 22;17(2):231-244. doi: 10.1016/j.jcin.2023.10.065.

Abstract

Background: Transcatheter pulmonary valve replacement (TPVR) has expanded and evolved since its initial commercial approval in the United States in 2010.

Objectives: This study sought to characterize real-world practice, including patient selection, procedural outcomes, complications, and off-label usage.

Methods: Characteristics and outcomes for patients undergoing balloon-expandable TPVR were collected from the American College of Cardiology National Cardiovascular Data Registry IMPACT (Improving Pediatric and Adult Congenital Treatment) Registry.

Results: Between April 2016 and March 2021, 4,513 TPVR procedures were performed in patients with a median age of 19 years, 57% with a Melody (Medtronic Inc) and 43% with a SAPIEN (Edwards Lifesciences) valve. Most implanting centers performed <10 cases annually. One-third of transcatheter pulmonary valve implants were into homograft conduits, one-third were into bioprosthetic valves (BPVs), 25% were in native or patched right ventricular outflow tracts (RVOTs), and 6% were into Contegra (Medtronic Inc) conduits. Over the course of the study period, SAPIEN valve use grew from ∼25% to 60%, in large part because of implants in patients with a native/patched RVOT. Acute success was achieved in 95% of patients (95.7% in homografts, 96.2% in BPVs, 94.2% in native RVOTs, and 95.4% in Contegra conduits). Major adverse events occurred in 2.4% of procedures, more commonly in patients with a homograft (2.9%) or native RVOT (3.4%) than a prior BPV (1.4%; P = 0.004).

Conclusions: This study describes novel population data on the use and procedural outcomes of TPVR with balloon-expandable valves. Over time, there has been increasing use of TPVR to treat regurgitant native RVOT anatomy, with the SAPIEN valve more commonly used for this application.
