Pediatric cardiac computed tomography angiography: Expert consensus from the Filiale de Cardiologie Pédiatrique et Congénitale (FCPC) and the Société Française d’Imagerie Cardiaque et Vasculaire diagnostique et interventionnelle (SFICV)

This article was designed to provide a pediatric cardiac computed tomography angiography (CCTA) expert panel consensus based on opinions of experts of the Société Française d’Imagerie Cardiaque et Vasculaire diagnostique et interventionnelle (SFICV) and of the Filiale de Cardiologie Pédiatrique Congénitale (FCPC). This expert panel consensus includes recommendations for indications, patient preparation, CTA radiation dose reduction techniques, and post-processing techniques. The consensus was based on data from available literature (original papers, reviews and guidelines) and on opinions of a group of specialists with extensive experience in the use of CT imaging in congenital heart disease. In order to reach high potential and avoid pitfalls, CCTA in children with congenital heart disease requires training and experience. Moreover, pediatric cardiac CCTA protocols should be standardized to acquire optimal images in this population with the lowest radiation dose possible to prevent unnecessary radiation exposure. We also provided a suggested structured report and a list of acquisition protocols and technical parameters in relation to specific vendors.     

Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery: Diagnoses and Surgical Results in 12 Pediatric Patients

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital condition. It responds well to early diagnosis and treatment, but otherwise the prognosis is poor. We present our case series of 12 patients (mean age, 2 ± 2.58 yr; age range, 2 mo–8 yr), emphasizing the diagnostic process and discussing our surgical results. The diagnosis of ALCAPA should be suspected in infants who have dilated cardiomyopathy with electrocardiographic changes that suggest ischemia, and in older children who have isolated mitral regurgitation. When clinical suspicion is high, the results of 2-dimensional echocardiography combined with color-flow Doppler studies in expert hands can establish the diagnosis, thus avoiding angiography in critically ill infants. The treatment of choice in our patients was transfer and reimplantation of the left coronary artery onto the ascending aorta. There were 2 deaths: both were infants in extremis who underwent emergency surgery. An older child with severe ventricular dysfunction was given mechanical ventricular assistance and then heart transplantation. As of this report, all 10 survivors remained well and asymptomatic.     

急性心肌梗死患者D二聚体质量浓度与远期预后的关系

目的 探讨急性心肌梗死(acute myocardial infarction,AMI)患者D二聚体(D-dimer)质量浓度与病情严重程度和远期心源性死亡的关系。方法 选取2013年1月至2020年1月收入首都医科大学附属北京友谊医院的AMI患者3 990例,根据D-dimer质量浓度分为3组:≤0.50 mg/L、0.51～0.80 mg/L、≥0.81 mg/L,平均随访时间为2.1 (1.0～4.0) 年。应用Cox比例风险回归模型评估D-dimer对心源性死亡的影响。结果 D-dimer≥0.81 mg/L组患者年龄较大、女性居多、体质量指数较低,既往合并高血压、糖尿病者较多,3支病变较为多见,住院期间肾小球滤过率较低,N末端B型利钠肽原峰值明显升高,左室射血分数<50%患者比例明显升高。D-dimer≥0.81 mg/L组患者在随访期间累计心源性病死率(18.7%)高于D-dimer≤0.50 mg/L组(2.3%)和D-dimer 0.51～0.80 mg/L组(6.1%),且校正其他危险因素后,D-dimer能独立预测AMI患者的心源性死亡(HR=1.71,95%CI:1.34~2.18,P<0.001)。结论 D-dimer能反映AMI患者病情的严重程度,且D-dimer升高可在一定程度上预测AMI患者远期心源性死亡事件发生率升高。
