Expanded polytetrafluoroethylene conduits and patches with bulging sinuses and fan-shaped valves in right ventricular outflow tract reconstruction: Multicenter study in Japan
چکیده انگلیسی

ObjectiveThere is no optimal substitute for right ventricular outflow tract (RVOT) reconstruction in congenital heart defects. Expanded polytetrafluoroethylene (ePTFE) valved conduits and patches may be a good alternative to homografts and bovine jugular veins. We have developed a fan-shaped ePTFE valve and an ePTFE valved conduit and patch with bulging sinuses with the aim of enhancing the long-term valve function.MethodBulging sinuses were constructed on ePTFE conduits and patches as described previously (J Thorac Cardiovasc Surg. 2007;134:327-32). Between February 2001 and January 2011, 794 patients (aged 14 days to 56.8 years old; median, 2.0 years old) had ePTFE valves implanted for RVOT reconstruction at 52 Japanese institutes. Conduits with a fan-shaped ePTFE valve were implanted in 325 patients and a patch with a fan-shaped ePTFE valve was implanted in 469 patients. Valve function was assessed by a series of echocardiograms postoperatively.ResultsThe mean follow-up was 3.6 years (1.1 months to 10.0 years). Freedom from reoperation at 10 years was 95.4% in patients with conduits and 92.3% in those with patches. Pulmonary insufficiency was mild or nonexistent in 95.0% of patients with conduits and 79.6% of patients with patches. The pressure gradient between the right ventricle and the pulmonary artery was 14.0 ± 13.2 mm Hg in patients with conduits and 11.6 ± 11.6 mm Hg in patients with patches.ConclusionsFan-shaped ePTFE valved conduits and patches with bulging sinuses have a high freedom from reoperation and prevent pulmonary insufficiency. They represent a promising material for RVOT reconstruction.
