Objective: To describe the experience of percutaneous pulmonary valve implantation (PPVI) in a cardiovascular referral hospital in Colombia. Method: A series of 10 cases of PPVI in a cardiovascular reference center in Colombia in a 6-year period (2018-2024) are presented. Results: Nine patients cases required Melody valve and one patient Myval valve. The most common congenital heart diseases were tetralogy of Fallot and pulmonary valve stenosis. The average age of intervention was 19.5 years. The most common type of lesion was pulmonary stenosis. The average valve/duct dysfunction in the pulmonary position prior to PPVI was 11.1 years. The average functional class before PPVI was III/IV and afterward I/IV. Conclusions: PPVI represented a less invasive alternative to relieve injuries in the right ventricular outflow tract compared to surgery, being a viable option with safe and effective results in the patients of this study.
