Dissections after percutaneous transluminal coronary angioplasty (PTCA) are risk factors for acute or subacute vessel closures. Intracoronary stenting was developed to avoid these complications by pressing the intimal and medial flaps against the vessel wall, thus reducing the risk of acute closure from thrombus formation. Thirty three coil (Gianturco-Roubin) stents were implanted into the coronary arteries of 32 patients with dissections after PTCA during the period of March 1993 to December 1993. The indications for stent implantation were acute closure in 6 (18.8%), threatened closure in 6 (18.8%) and suboptimal result in 20 (62.4%) patients. Stent insertion were successful in 30 (94%) patients. The diameter stenosis in an immediate angiographic findings after stenting was decreased from 87% to 18% by caliper estimation. Emergency coronary artery bypass graft surgery was required in 1 (3%) patient. A non-Q wave myocardial infarction occurred in 1 (3%) patient. Complications included hematoma of the arterial access site requiring blood transfusion in 4 (12.5%) patients and hemopericardium in 1 (3%) patient. Our initial clinical experience of flexible coil coronary stent imply that stenting is efficacious treatment for acute dissections that are causing acute or threatened closure following angioplasty. The long term follow-up result in all groups of patient who received coronary stents is needed for better evaluation of new devices and prognosis.

OBJECTIVE:
To study the clinical effect and safety of clopidogrel combined with aspirin in antithrombotic therapy for children with Kawasaki disease (KD) complicated by coronary artery aneurysm (CAA).
METHODS:
A total of 77 KD children who were diagnosed with multiple small/medium-sized CAAs by echocardiography between January 2013 and June 2018 were enrolled. They were randomly divided into observation group with 38 children (treated with clopidogrel and aspirin) and control group with 39 children (treated with low-molecular-weight heparin and aspirin). All children were followed up regularly, and the first 3 months of the course of the disease was the observation period. The children were observed in terms of the change of the coronary artery and the incidence of complications.
RESULTS:
At month 3 of follow-up, among the children in the observation group, 6 had normal coronary artery, 11 had coronary artery retraction, 19 had stable coronary artery, and 2 progressed to giant coronary aneurysm; among the children in the control group, 7 had normal coronary artery, 12 had coronary artery retraction, 19 had stable coronary artery, and 1 progressed to giant coronary aneurysm; there was no significant difference in the change of the coronary artery between the two groups (P>0.05). There were 2 cases of epistaxis and 6 cases of skin ecchymosis in the observation group, and 1 case of epistaxis and 7 cases of petechiae and ecchymosis at the injection site in the control group, and no other serious bleeding events were observed in either group.
CONCLUSIONS
Clopidogrel combined with low-dose aspirin is safe and effective in antithrombotic therapy for children with KD complicated by CAA.

Kawasaki Disease (KD) is an acute, febrile, multisystem disease of children. More severe complications in 15~25% of cases include, the development of coronary aneurysms, ischemic heart disease, and sudden cardiac death. The standard treatment for significant coronary artery stenosis has generally been aortocoronary bypass surgery, although percutaneous transluminal coronary angioplasty (PTCA) has been described in a small number of patients. This report describes a 14 year old boy with a history of KD who developed multiple coronary aneurysms and stenosis. We performed PTCA, which was successful in relieving the stenosis of the left circumflex artery.

OBJECTIVETo evaluate risk factors and clinical outcome of coronary artery aneurysms (CAA) developed after drug-eluting stent implantation evidenced by coronary angiographic follow-up.
METHODSThis study analyzed 4500 consecutive patient with de novo coronary artery stenosis receiving drug-eluting stent (DES) implantation from January 2004 to May 2009. Seven hundred and sixty patients with angiographic follow-ups at 6 - 8 months and 28 - 48 months after the index procedure were enrolled. CAA was defined as a localized dilatation exceeding 1.5 times the diameter of the adjacent artery. The independent risk factors and major adverse cardiac events (MACE) including cardiac death, myocardial infarction, target-vessel revascularization (TVR) and in-stent thrombosis were analyzed.
RESULTSCAA was detected in 70 patients with 70 lesions (9.2%, 70/760). Logistic analysis showed that lesion in an infarct-related artery (OR: 5.9, P < 0.01), lesion in the left anterior descending artery (OR: 4.5, P < 0.01), lesion with chronic total occlusion (OR: 3.4, P < 0.05), and lesion length > 33 mm (OR: 2.9, P < 0.05) were independent risk factors for CAA. Follow-up duration was (1131 ± 478) days. MACE was found in 19 patients and all received TVR. There were 11 patients with myocardial infarction and 8 patients with evidence of in-stent thrombosis. Mortality was zero during follow-up.
CONCLUSIONSThe risk factors for the development of CAA after DES are lesions in an infarct-related artery, in the left anterior descending artery, with chronic total occlusion, and with lesion length > 33 mm. MACE is not uncommon in patients with CAA and long-ferm clinical follow-up is warranted for patients with CAA.

OBJECTIVEThe aim of the study was to review the cases of Kawasaki Disease (KD) and analyze the clinical features especially their cardiac complications.
METHODSTotally 283 patients with KD were hospitalized from 1992 to 2002. Their clinical features and factors associated with increased risk of coronary artery aneurysms were reviewed.
RESULTS(1) Among the 283 KD patients, 186 were male and 97 were female. The male-female ratio was 1.9:1. Most of them (71%) were younger than 3 years old. Seasonal peak was in spring and summer (from May to Aug). Depending on the criteria of KD, 228 (81%) were diagnosed as typical KD and 55 (19.4%) were atypical KD. All patients had fever, lasting for 6.1 days. The most common clinical features were oral mucosal changes (97.5%) and cervical lymphadenopathy (95.4%), conjunctivitis (91.2%). And changes in the extremities (89.8%) and rash (81.5%) were also noted. (2) Before the treatment, coronary artery abnormalities were seen in 103/279 (36.9%), which occurred within 4 - 30 days of fever onset. Two weeks after intravenous gamma globulin (IVIG) treatment, the new cases of coronary artery abnormalities were 28/211 (13.3%). The prevalence of coronary artery aneurysms (CAA) with KD was 4.7%. The risk factors of CAA were male cases (P < 0.05) and fever lasting longer than 9 days (P < 0.05). Other cardiac abnormalities in acute phase included left atrial and ventricular enlargement (40/279, 14.3%) and changes in ECG (57/274, 20.8%). The pericardial effusions were found in 11 cases (3.9%).
CONCLUSIONSCardiac complications of KD occurred in the early period of KD. The new cases of coronary artery abnormalities were 13.3% after IVIG treatment. The risk factors of CAA included male cases and fever lasting for longer time.

OBJECTIVES:
To examine the association between duration of fever before intravenous immunoglobulin (IVIG) treatment and IVIG resistance in children with Kawasaki disease (KD).
METHODS:
A retrospective analysis was performed on the medical data of 317 children with KD who were admitted from January 2018 to December 2020. According to the duration of fever before IVIG treatment, they were divided into two groups: short fever duration group (≤4 days) with 92 children and long fever duration group (>4 days) with 225 children. According to the presence or absence of IVIG resistance, each group was further divided into a drug-resistance group and a non-drug-resistance group. Baseline data and laboratory results were compared between groups. A multivariate logistic regression analysis was used to identify the influencing factors for IVIG resistance.
RESULTS:
In the short fever duration group, 19 children (20.7%) had IVIG resistance and 5 children (5.4%) had coronary artery aneurysm, and in the long fever duration group, 22 children (9.8%) had IVIG resistance and 19 children (8.4%) had coronary artery aneurysm, suggesting that the short fever duration group had a significantly higher rate of IVIG resistance than the long fever duration group (P<0.05), while there was no significant difference in the incidence rate of coronary artery aneurysm between the two groups (P>0.05). In the short fever duration group, compared with the children without drug resistance, the children with drug resistance had a significantly lower level of blood sodium and significantly higher levels of procalcitonin, C-reactive protein, and N-terminal B-type natriuretic peptide before treatment (P<0.05). In the long fever duration group, the children with drug resistance had significantly lower levels of blood sodium and creatine kinase before treatment than those without drug resistance (P<0.05). The multivariate logistic regression analysis showed that a reduction in blood sodium level was associated with IVIG resistance in the long fever duration group (P<0.05).
CONCLUSIONS
IVIG resistance in children with KD varies with the duration of fever before treatment. A reduction in blood sodium is associated with IVIG resistance in KD children with a duration of fever of >4 days before treatment.

Objective: To investigate the efficacy and safety of infliximab (IFX) therapy for children with Kawasaki disease. Methods: Sixty-eight children with Kawasaki disease who received IFX therapy in Children's Hospital of Fudan University from January 2014 to April 2021 were enrolled. The indications for IFX administration, changes in laboratory parameters before and after IFX administration, response rate, drug adverse events and complications and outcomes of coronary artery aneurysms (CAA) were retrospectively analyzed. Comparisons between groups were performed with unpaired Student t test or Mann-Whitney U test or chi-square test. Results: Among 68 children with Kawasaki disease, 52 (76%) were males and 16 (24%) were females. The age of onset was 2.1 (0.5, 3.8) years. IFX was administered to: (1) 35 children (51%) with persistent fever who did not respond to intravenous immunoglobulin (IVIG) or steroids, 28 of the 35 children (80%) developed CAA before IFX therapy; (2) 32 children (47%) with continuous progression of CAA; (3) 1 child with persistent arthritis. In all cases, IFX was administered as an additional treatment (the time from the onset of illness to IFX therapy was 21 (15, 30) days) which consisted of second line therapy in 20 (29%), third line therapy in 20 (29%), and fourth (or more) line therapy in 28 (41%). C-reactive protein (8 (4, 15) vs. 16 (8, 43) mg/L, Z=-3.38, P=0.001), serum amyloid protein A (17 (10, 42) vs. 88 (11, 327) mg/L, Z=-2.36, P=0.018) and the percentage of neutrophils (0.39±0.20 vs. 0.49±0.21, t=2.63, P=0.010) decreased significantly after IFX administration. Fourteen children (21%) did not respond to IFX and received additional therapies mainly including steroids and cyclophosphamide. There was no significant difference in gender, age at IFX administration, time from the onset of illness to IFX administration, the maximum coronary Z value before IFX administration, and the incidence of systemic aneurysms between IFX-sensitive group and IFX-resistant group (all P>0.05). Infections occurred in 11 cases (16%) after IFX administration, including respiratory tract, digestive tract, urinary tract, skin and oral infections. One case had Calmette-Guérin bacillus-related adverse reactions 2 months after IFX administration. All of these adverse events were cured successfully. One child died of CAA rupture, 6 children were lost to follow up, the remaining 61 children were followed up for 6 (4, 15) months. No CAA occurred in 7 children before and after IFX treatment, while CAA occurred in 54 children before IFX treatment. CAA regressed in 23 (43%) children at the last follow-up, and the diameter of coronary artery recovered to normal in 10 children. Conclusion: IFX is an effective and safe therapeutic choice for children with Kawasaki disease who are refractory to IVIG or steroids therapy or with continuous progression of CAA.

Objective: To investigate the clinical characteristics of systemic juvenile idiopathic arthritis combined with coronary artery dilatation. Methods: A retrospective analysis was performed on the clinical data, including clinical manifestations, blood routine, inflammatory factors, echocardiography, vascular ultrasound and CT angiography, treatment and outcomes, etc, of 5 cases with systemic juvenile idiopathic arthritis combined with coronary artery dilation admitted to Department of Rheumatology in the affiliated Children's Hospital of Capital Institute of Pediatrics from May 2019 to June 2021. Results: There were 2 males and 3 females among 5 cases. The onset age ranged from 7 months to 4 years 7 months.The diagnostic time ranged from 1.5 months to 3.0 months.Four cases were diagnosed as atypical Kawasaki disease. Three cases showed unilateral coronary artery dilation.Two cases showed bilateral coronary artery dilation.Four cases developed multiple organ injuries.Three cases developed macrophage activation syndrome.Three cases developed lung injury.Two cases developed pericardial effusion.One case developed pulmonary hypertension.As for treatment, 3 cases treated with methylprednisolone pulse therapy and methotrexate combined with cyclosporine, improved after the final application of biological agents, and have stopped prednisone. The other 2 cases were treated with adequate oral prednisone and gradually reduced, and methotrexate was added at the same time, 1 case relapsed in the process of reduction. No other vascular involvement was found in 5 cases. Coronary artery dilation recovered completely after 1 to 3 months of treatment. Conclusions: Systemic juvenile idiopathic arthritis combined with coronary artery dilatation has the clinical characteristics of small onset age, long diagnostic time, prone to multiple organ injuries. Corticosteroids and conventional immunosuppressive agents are not sensitive, and biological agents should be used as soon as possible.The prognosis of coronary artery dilation is good after timely treatment.
