| Summary: | Objectives: To report our experience using the 10-zig C-P stents in children and adults with congenital heart disease. Background: The use of stents in congenital heart disease has become widespread since the 1990s and a large range of stents has been designed for a variety of indications. In many situations there is a need for stents that can be dilated to large diameters without excessive shortening. Cheatham-Platinum (10-zig C-P) (NuMED, Hopkinton, NY, USA.) stents may fulfil this requirement. Methods: Between January 2015 and January 2020, 17 patients with congenital heart disease were treated using a 10-zig C-P stent at our center. (6 Females 13 males; (median age 33 years (range 10–69 years); median weight 85 kgs (range 25–119 kg). Indications for use of the 10-zig stents were right ventricular outflow tract (RVOT) interventions in 8 subjects and aortic coarctation in 9 patients. Results: 1) Right ventricular outflow tract stenting. Ten right ventricular outflow tract stents (2 also had implantation of transcatheter valves in the same procedure) were implanted in 8 patients. All the RVOT interventions were in preparation for a transcatheter pulmonary valve. Median fluoroscopy and procedure times were 41 min (range 31–131 min) and 164 min (range 152–361 min), respectively. One patient had distal perforation of a pulmonary artery due to guide-wire injury and required blood products. Two subjects showed stent fracture during follow-up needing further stent implantation. 2) Aortic Coarctation. Nine stents were implanted in 9 patients. The median fluoroscopy and procedure times were 36 min (range 11–75 min) and 164 min (range 95–225 min), respectively. The median peak systolic gradient reduced from 33 mmHg (range 15–60 mmHg) to 3 mmHg (range 0–4 mmHg) (p < 0.001). Conclusions: Our experience shows that the 10-zig Cheatham-Platinum stents can be used successfully and safely in congenital heart diseases.
