Background: Transcatheter pulmonary valve implantation (TPVI) has become an important alternative to surgical pulmonary valve replacement in selected patients with right ventricular outflow tract dysfunction. Objective: To review recent advances, procedural outcomes, clinical applications, and future directions of TPVI. Methods: This narrative review summarizes current evidence on TPVI devices, patient selection, imaging, procedural techniques, complications, and real-world outcomes. Results: TPVI has demonstrated high procedural success, reduced need for repeat sternotomy, improved right ventricular function, and symptomatic benefit in patients with dysfunctional conduits, bioprosthetic pulmonary valves, and selected native outflow tracts. Conclusion: TPVI is a major advancement in congenital and structural heart intervention. Continued device development and improved imaging have expanded its application to broader patient groups.
