Abstract
BACKGROUND: Right ventricular outflow tract (RVOT) dysfunction is a long-term postsurgical complication of tetralogy of Fallot (TOF) that needs long-term multidisciplinary treatment. CASE SUMMARY: We report a case of TOF patient who underwent radical surgical repair in infancy and who presented with pulmonary artery stenosis and pulmonary regurgitation during follow-up. Pulmonary stent placement and percutaneous pulmonary valve implantation (PPVI) were pursued successfully when he was aged 5 and 13 years, respectively. DISCUSSION: PPVI has been widely used as a minimally invasive treatment alternative to surgical pulmonary valve replacement. This technology has shown significant advantages in pediatric patients to improve RVOT dysfunction, relieve symptoms, optimize hemodynamic parameters, and avoid reintervention. TAKE-HOME MESSAGE: This case provides a long-term and multidisciplinary strategy for TOF in pediatrics, with a focus on the possibility and effect of PPVI in adolescent patients.
