“…Although the long-term result still needs to be clarified, follow-up catheterization showed that rate of re-stenosis and percent stenosis remained relatively low after intervention. However, dilatation over 14 mm, the normal typical pulmonary artery size of an adult, is potentially harmful to the vessel when using over a 12 Fr sheath for delivering a bulky stent such as the Palmaz® genesis stent (Johnson & Johnson-Cordis, Bridgewater, NJ, USA) 10)11)15)…”

Background and ObjectivesPulmonary arterial stenosis is a relatively common complication after corrective operation of congenital heart disease. Unilateral stenosis of pulmonary arteries could result in decrease perfusion of affected lung, pulmonary regurgitation, or elevation of right ventricular pressure. Eventually there are increasing risks of right ventricular failure, arrhythmia, or sudden death. However we have limited data of pulmonary arterial stent in paediatric population as the treatment of branch pulmonary stenosis. This study aimed at validating the effectiveness and investigating complications of pulmonary arterial stent implantation in a single institution during mid-term follow up period.Subjects and MethodsA total of 42 patients (50 stents) were implanted for treating branch pulmonary arterial stenosis. We used cardiac catheterization for comparing diameter after stent implantation directly and lung perfusion scan indirectly. We also investigated any adverse effect relating the procedure.ResultsPercent stenosis of stenotic lesions were decreased from 54.1±10.7% to 22.8±12.5% (p<0.001) and degree of decrement in affected lung perfusion was declined from 22.7±8.0% to 10.3±9.0% (p<0.001) immediately and lasts during mid-term follow up period. Complication rate relating the procedure was 12% (6 out of 12) and there was no mortality case.ConclusionThis series showed immediate and short term effectiveness of pulmonary arterial stent in congenital heart defects. We concluded that percutaneous transcatheter implantation of pulmonary arterial stent was safe and effective during short and mid-term follow up period.

Limitations of the currently available balloon-expandable stainless steel (BE-SS) stents for use in patients with congenital heart defects (CHD) include inflexibility, significant shortening with expansion, sharp ends, and limited sizes. These limitations increase risk and greatly effect success of stent placement in these patients. The recently approved IntraStent DoubleStrut LD (IS-LD) stents are BE-SS stents designed to address such limitations. We report our initial experience with IS-LD stents in patients with CHD. Using standard techniques, 36 stents were implanted in 22 patients whose median age was 11 years (range, 1.4-35 years) and weight was 33 kg (range, 9-96.8 kg). Lesions stented included aortic coarctation (4), branch pulmonary arteries (19), inferior or superior vena cava (11), Mustard baffle (1), and Fontan baffle (1). All attempts at stent placement were successful. Hemodynamic assessment and angiography was performed pre- and poststent placement in all patients. Intravascular ultrasound was performed in four patients. Stenosis diameter increased from 5.7 +/- 0.6 mm (mean +/- SD) to 11.6 +/- 0.5 mm (P < 0.001). Stents did not shorten significantly with dilation (median percent shortening, 3.8%; P > 0.1). Complications included stent recoil (2), stent migration (1), and stent distortion (1). IS-LD stents are a safe and effective treatment for the majority of vascular stenoses in patients with CHD. Stent recoil at large diameters may limit its usefulness in selected lesions. Follow-up studies are required to determine the long-term performance of IS-LD stents.
