Purpose: The efficacy of percutaneous stent implantation for congenital heart disease (CHD) in Korea, where stent availability is limited, has not been determined. This study evaluated the acute and midterm results of stent implantation in different CHD subgroups. Methods: Stents were implanted in 75 patients with 81 lesions: (1) pulmonary artery stenosis (PAS) group, 56 lesions in 51 patients; (2) coarctation of the aorta (CoA) group, 5 lesions in 5 patients; (3) Fontan group, 13 lesions in 12 patients; (4) ductal stent group, 3 lesions in 3 patients; and (5) other CHD group, 4 lesions in 4 patients. Mean follow-up duration was 2.1 years (0.1-4 years). Medical records were reviewed retrospectively. Results: The minimum lumen diameter (MLD) in PAS and CoA increased from $5.0{\pm}1.9mm$ and $8.4{\pm}1.6mm$ to $10.1{\pm}3.6mm$ and $12.3{\pm}2.5mm$, respectively (P<0.01). In the PAS group, pressure gradient decreased from $25.7{\pm}15.6mmHg$ to $10.4{\pm}10.1mmHg$, and right ventricular to aortic pressure ratio from $0.56{\pm}0.21$ to $0.46{\pm}0.19$. In the CoA group, the pressure gradient decreased from $50{\pm}33mmHg$ to $17{\pm}8mmHg$. In the ductal stent group, the MLD of the ductus increased from 2.3 mm to 4.3 mm and arterial oxygen saturation from 40%-70% to 90%. No deaths were associated with stent implantation. Stent migration occurred in 3 patients, but repositioning was successful in all. Stent redilation was performed successfully in 26 cases after $29{\pm}12months$. Conclusion: Percutaneous stent implantation was safe and effective, with acceptable short and mid-term outcomes in Korean CHD patients.
