Evaluation of treatment and management of Kawasaki coronary artery disease based on clinical severity classification / 中华儿科杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of evaluation,treatment and follow-up of Kawasaki coronary artery disease based on the clinical severity classification.</p><p><b>METHOD</b>This study evaluated 52 patients admitted to the Children's Hospital of Fudan University between July 2005 and December 2013 who were diagnosed with Kawasaki Disease with coronary artery disease.Inclusion criteria were a disease course of more than two months, initial echocardiography showing severity of grade IV and above, and confirmation of disease severity by angiography. Of those studies, 44 were male and eight were female, aged 6 to 142 (average 41) months. Treatment was planned according to protocols in "Suggestions for Management of Kawasaki Coronary Artery Disease" with follow-up. Those patients with grade IV and above confirmed by angiogram were given oral low-dose asprin and warfarin, and those with grade Vb were given coronary artery bypass grafting (CABG) after comprehensive evaluation. Analysis was carried out for diagnosis, treatment, complications, and results of follow-up.</p><p><b>RESULT</b>(1) Satisfied images were shown by the angiography of all 52 cases. Forty five patients (86%) had giant aneurysm or multiple aneurysms, with thrombosis found in 10 of 45 patients (22%). Coronary artery lesions occurred in 138 coronary branches, and more common in left anterior descending branch (47 branches, with incidence 34%) and right coronary artery (48 branches, with incidence 35%). There were no complications during or after angiography. (2) After angiography, 49 patients remained at grade IV or above, and three improved to grade III. Ultimately, clinical severities of coronary artery disease included three patients at grade III, 31 patients at grade IV, nine patients at grade Va, and nine patients at grade Vb. (3) Thirty-eight patients were properly using aspirin and warfarin, and two patients with severely elevated international normalized ratio (INR) levels presented with knee joint and gastric hemorrhage, both of which were treated successfully.Patients with INR levels between 1.5 and 2.5 did not show signs of hemorrhage. (4) In follow-up visits between 6 months and 8 years, one patient had representation of thrombosis on angiography, but did not lead to coronary stenosis; four patients were improved from grade IV to either grade III or II. The remaining showed no new thrombotic formation or stenosis. (5) Of the nine grade Vb patients, five underwent coronary artery bypass grafting. The youngest of these patients, a 22 months old girl, died intraoperatively. The remaining four recovered postoperatively and were followed up for 8 to 90 months. One patient had a preoperative left ventricular ejection fraction (LVEF) of only 32.8%, with LVEF remaining abnormal post-CABG, between 35% and 44%. The remaining three patients had normal heart size, cardiac function, and electrocardiogram.Of the other four grade Vb patients, two were contraindicated for surgery due to severe heart failure and loss of myocardial activity. Two other cases are being followed up closely due to their young age of 9 months.</p><p><b>CONCLUSION</b>Coronary angiography is safe and efficacious in children, and even in infants.It is the current gold standard tool for grading Kawasaki coronary artery disease. Proper anticoagulation therapy can markedly decrease the incidence of coronary artery occlusion in patients with Kawasaki coronary artery disease. Safe ranges of corrected INR should be between 1.5 and 2.5 after taking warfarin. CABG is an effective treatment for severe coronary artery disease with myocardial ischemia.</p>

Role of real-time three dimensional echocardiography in the assessment of right ventricular function of repaired tetralogy of Fallot / 中华实用儿科临床杂志

Objective To evaluate the clinical value of real-time 3 dimensional echocardiography (RT-3DE) for measurement of right ventricular function in the repaired tetralogy of Fallot (TOF) compared to cine magnetic resonance imaging (c-MRI).Methods Thirty-seven randomly selected patients with repaired TOF from Jan.2000 to Jun.2007 in Children's Hospital,Fudan University underwent both RT-3DE and c-MRI for the data of right ventricular enddiastolic volume (RVEDV),right ventricular end-systolic volume (RVESV),right ventricular ejection fraction (RVEF),which were compared to evaluate the reproducibility and correlation of two ways on right ventricular function.Results All the patients completed both RT-3DE and c-MRI on the same day.The correlation for RVEDV,RVESV,RVEF measured by 2 methods was high (r =0.933,0.943,0.911,P =0.000,0.000,0.105),and it showed that consistency existed in RVEF,as difference was only (1.2 ± 4.5) ％.Comparison with c-MRI,RVEDV and RVESV measured by RT-3DE was underestimated,in which difference was (-17.4 ± 16.9) mL,(-9.3 ± 10.5) mL.Conclusions RVEF with RT-3DE can be assessed with acceptable accuracy,but it is not so good for RVEDV and RVESV.Further study needs to be performed to make sure the value of RT-3DE on the assessment of right ventricular function in repaired TOF.
