Objective:To investigate the clinical manifestations, pathological characteristics, treatment and prognosis of pediatric rheumatic carditis with the initial symptom of acute heart failure, and to improve the clinical understanding of the disease.Methods:The clinical data, laboratory examination results, imaging findings, treatment and prognosis data of 10 cases with acute rheumatic carditis were collected and analyzed retrospectively.The patients pre-sented with acute heart failure as the first symptom and were treated in Shenzhen Children′s Hospital from January 2015 to February 2022.Results:There were 4 males and 6 females in this study.The mean age was 9.1 years (3 years and 1 month to 11 years and 3 months), and the average onset age was (9.3 ± 3.2) days (4-14 days). All the 10 cases had circulation symptoms.Besides, 4 cases were also complicated with joint symptoms, 3 cases with neurological symptoms and 2 cases with skin symptoms.Echocardiography revealed mitral valve diseases in all cases.More specifically, combined valve diseases were found in 5 cases, pure mitral regurgitation in 3 cases, and mixed mitral valve diseases (mitral regurgitation complicated with mitral stenosis) in 2 cases.After receiving antibiotic therapy, anti-infection treatment and anti-heart failure therapy, symptoms improved in all patients and valve lesions were alleviated.All patients were followed up for 6 months to 6 years.Six cases had persistent rheumatic heart disease during the follow up.Conclusions:Pediatric rheumatic carditis with the initial symptom of acute heart failure is characterized by early onset and the typical manifestation of rheumatic fever.Mitral valve disease is the commonest lesion.Echocardiography is of great value for the early diagnosis of the disease.Medical treatment is effective, but the incidence of chronic rheumatic heart disease is still high.

Objective:To evaluate the effectiveness of interventional treatment for neonatal critical pulmonary stenosis(NCPS).Methods:Clinical data of 12 neonates with NCPS who received percutaneous balloon pulmonary valvuloplasty (PBPV) from January 2016 to December 2019 in Department of Cardiology, Shenzhen Children′s Hospital were summarized and analyzed.The collected data included transthoracic echocardiography (TTE), percutaneous oxygen saturation (SPO 2), relevant data on interventional surgery, and follow-up results. Results:All 12 neonates with NCPS received PBPV successfully.The postoperative pressure difference between the right ventricle and the pulmonary artery ranged from 8 to 35 mmHg[(20±7) mmHg, 1 mmHg=0.133 kPa]. The postoperative SPO 2 ranged from 74%-100%[(93.0±5.9)%]. Three neonates with NCPS received Blalock-Taussig (B-T) shunt.One neonate with NCPS developed supraventricular tachycardia during the operation.There was no death for these 12 neonates with NCPS. Conclusions:Interventional treatment of neonates with NCPS could achieve a better effect and be employed as the first treatment option.Some neonates with NCPS would require cardiac B-T shunt or patent ductus arteriosus stent implantation.
Résumé
Kawasaki disease (KD) is one of the acute vasculitis diseases, and its most common complications are coronary artery lesions and myocarditis.Different degrees of myocardial injury can be observed in the acute phase of KD, and different abnormal waveforms can be detected in the electrocardiogram (ECG). As a noninvasive electrophysiological examination, ECG is of great significance for both early diagnosis and prognosis evaluation of KD.The advance in research enables ECG manifestations and electrophysiological significance in the early phase of KD to be gradually re-cognized.In this article, the foreign and domestic research on the changes and clinical significance of ECG in acute stage of Kawasaki disease in recent years was reviewed and summarized, and recent advance in the application of ECG in the acute phase of KD was also summarized.
