About

To investigate the safety and long-term vascular remodeling after bioresorbable vascular scaffold (BVS) implantation for stenotic or occluded lesion in children or young adults with Kawasaki disease (KD).

Background: KD occurs worldwide, most prevalent in Japan and East Asian countries. Coronary artery lesion is the predominant determinant of KD outcome in the long-term. Children with KD with aneurysms at least 6 mm in maximal diameter had a greater than 50% chance of developing a clinically significant stenotic lesion during follow-up. They are at risk of myocardial infarction-related sudden death or congestive heart failure as young adults. Bypass surgery could be the reasonable strategy but the long-term patency of the graft remains unsatisfactory. Percutaneous angioplasty with drug-eluting stents (DES) implantation is the alternative. However, metallic stenting remains problematic in several aspects mainly due to the restriction of vessel expansive remodeling. The novel BVS has the potential to be free from the limitation due to scaffold degradation.

Full description

we will conduct a single-center, single-group prospective study with safety and imaging endpoints. A total of 10 KD children or young adults with indication of revascularization are enrolled, and BVS will be implanted for stenotic or occluded lesions. QCA and optical coherence tomography (OCT) are used to evaluate the baseline lumen area, plaque characteristics, and BVS expansion or eccentricity after deployment. At 12 months, scaffold restenosis is evaluated by multislice computed tomography. At 30 months, patients will receive follow-up by angiography and OCT to evaluate lumen area, neoplaque characteristics, and side branch conditions. Otherwise, the composite endpoint including cardiac death, myocardial infarction, and ischaemia-driven target lesion revascularisation are assessed at 30 days, 6 and 9 months, and 1, 2, 3 years.

Inclusion criteria

In the single-group prospective study with safety and imaging endpoints, a total of 10 KD patients < 18 years will be enrolled.
The diagnosis of KD was made based on clinical criteria for KD.

Exclusion criteria

Patients presenting with an acute myocardial infarction or unstable arrhythmias, or those who has severe left ventricular dysfunction (ejection fraction less than 35%), intrastent restenotic lesions, lesions located in the left main coronary artery, and tight lesions which could not be well dilated even after rotational atherectomy are excluded. Those with chronic renal insufficiency (creatinine >1.5 mg/dl) are also excluded due to the limitation of OCT (optical coherence tomography) use.
