    右肺动脉异常起源于升主动脉是一种罕见的先天性心脏畸形,可导致婴儿早期死亡。这些患者有早期发展为显著肺动脉高压的风险。生命早期的手术管理势在必行。
    起源于升主动脉的异常肺动脉(通常称为半心)是一种罕见的先天性心脏缺陷,需要在新生儿期立即处理。我们报告了一例罕见的起源于升主动脉的右肺动脉异常变异,并伴有肺动脉闭锁和法洛四联症。上述组合使得这种心脏缺陷的外科治疗要求极高。
    UNASSIGNED: Anomalous origin of right pulmonary artery from the ascending aorta is a rare congenital heart malformation that results in early infant mortality. These patients are at risk for the early development of significant pulmonary hypertension. The surgical management during the early period of life is imperative.
    UNASSIGNED: Anomalous pulmonary artery originating from the ascending aorta (often called hemitruncus) is a rare congenital cardiac defect requiring immediate management in the neonatal period. We report a case of a rare variant of anomalous right pulmonary artery originating from the ascending aorta in combination with pulmonary atresia and tetralogy of Fallot. The above-mentioned combination makes the surgical management of such cardiac defect exceedingly demanding.

    体肺分流术和右心室-肺动脉(RV-PA)连接均广泛用于最初修复伴有室间隔缺损(PA/VSD)的肺动脉闭锁。然而,这些选择中哪一种最适合促进肺动脉发育和改善预后仍存在争议.
    本研究共纳入广东省人民医院2010年至2020年初次康复手术的109例PA/VSD患者。收集了一系列临床数据,以比较体肺和RV-PA连接的围手术期和术后结局。
    体肺分流术组的平均随访时间为61.1个月,RV-PA连接组为70.3个月(p>0.05)。RV-PA连接技术导致明显更高的PaO2,较低的红细胞(RBC),低血红蛋白,和较低的血细胞比容(Hct)(p<0.05)。累积发生率曲线估计RV-PA连接组5年后的累积完全修复率为56±7%,5年后,体肺分流组显著高于36±7%(p<0.05)。Kaplan-Meier曲线显示两组之间的估计生存率相似(p=0.73)。在多变量分析中,RV-PA连接被确定为完全修复的独立预测因子(HR=2.348,95%CI=1.131-4.873)。
    与体肺分流术相比,RV-PA连接是治疗PA/VSD的更理想的初始康复技术,其结果是生存概率相当,但最终完全修复率提高。
    UNASSIGNED: Both systemic-to-pulmonary shunt and right ventricle-pulmonary artery (RV-PA) connection are extensively applied to initially rehabilitate the pulmonary artery in pulmonary atresia with the ventricle septal defect (PA/VSD). However, which of these options is the most ideal for promoting pulmonary artery development and improving outcomes remains controversial.
    UNASSIGNED: A total of 109 PA/VSD patients undergoing initial rehabilitative surgery at Guangdong Provincial People\'s Hospital from 2010 to 2020 were enrolled in this study. A series of clinical data were collected to compare the perioperative and postoperative outcomes between systemic-to-pulmonary and RV-PA connection.
    UNASSIGNED: The mean duration of follow-up was 61.1 months in the systemic-to-pulmonary shunt group and 70.3 months in the RV-PA connection group (p > 0.05). The RV-PA connection technique resulted in a significantly higher PaO 2 , lower red blood cells (RBC), lower hemoglobin, and lower hematocrit (Hct) (p < 0.05). The cumulative incidence curve estimated a cumulative complete repair rate of 56 ± 7% after 5 years in the RV-PA connection group, significantly higher than 36 ± 7% after 5 years in the systemic-to-pulmonary shunt group (p < 0.05). The Kaplan-Meier curve revealed a similar estimated survival rate between the two groups (p = 0.73). The RV-PA connection was identified as an independent predictor for complete repair in the multivariable analysis (HR = 2.348, 95% CI = 1.131-4.873).
    UNASSIGNED: The RV-PA connection is a more ideal initial rehabilitative technique than systemic-to-pulmonary shunt in treating PA/VSD as a consequence of comparable probability of survival but improved definitive complete repair rate.

    背景:目前尚不清楚全身至肺动脉分流术中动脉导管未闭的最佳管理方法。这项研究的目的是检查Blalock-Taussig-Thomas分流手术期间动脉导管未闭管理的可变策略的结果。
    方法:对接受分流术的婴儿进行了回顾性队列研究,将结扎导管的人与保留导管的人进行比较。低心输出量综合征的指标,坏死性小肠结肠炎的发展,并检查了次要结局,如复苏事件.
    结果:36例婴儿均通过正中胸骨切开术进行分流术。20名婴儿在分流时结扎了导管,他们与16名导管开放的婴儿进行了比较。术前基线特征无统计学差异,包括矫正胎龄,以天为单位的年龄,体重,机械通气,血管活性的使用,异质,和肠胃异常.术后低心输出量指标也无统计学差异,包括尿液生产,给定的总流体,肾损伤,最大乳酸,和血管活性-正性肌力评分。3例患者术后肾损伤,都在结扎管组。任何次要结局也没有统计学差异,包括坏死性子宫内膜炎的发展,复苏事件,再干预,插管长度,总停留时间,和死亡率。
    结论:本研究提供了证据,证明分流术期间导管的可变管理不会显著影响结局。保持导管开放可以提供潜在的肺血流救援来源,并且似乎不会增加术后低心输出量的风险。
    BACKGROUND: The optimal approach to patent ductus arteriosus management during systemic-to-pulmonary artery shunt placement is currently unknown. The purpose of this study is to examine the outcomes of variable strategies for patent ductus arteriosus management during Blalock-Taussig-Thomas shunt surgery.
    METHODS: A retrospective cohort study of infants who underwent shunt placement was performed, comparing those who had the ductus ligated with those who had the ductus left open. Indicators of low cardiac output syndrome, development of necrotizing enterocolitis, and secondary outcomes such as resuscitation events were examined.
    RESULTS: Thirty-six infants were included all of whom had their shunt placed via median sternotomy. Twenty infants had their ductus ligated at the time of the shunt, and they were compared with 16 infants whose ductus was left open. There was no statistical difference in preoperative baseline characteristics, including corrected gestational age, age in days, weight, mechanical ventilation, vasoactive use, heterotaxy, and gastrointestinal anomalies. There was also no statistical difference in postoperative indicators of low cardiac output, including urine production, total fluids given, renal injury, maximum lactate, and vasoactive-inotropic score. Three patients had postoperative renal injury, and all were in the ligated duct group. There was also no statistical difference in any secondary outcomes, including the development of necrotizing eneterocolitis, resuscitation events, reinterventions, length of intubation, total length of stay, and mortality.
    CONCLUSIONS: This study provides evidence that variable management of the ductus during shunt placement does not significantly impact outcomes. Leaving the ductus open allows for a potential rescue source of pulmonary blood flow and does not appear to increase the risk of postoperative low cardiac output.

    主主动脉肺侧支动脉(MAPCAs)是罕见的先天性异常,具有重要的临床意义,常伴有先天性心脏病,如法洛四联症(TOF)和肺动脉闭锁(PA)。本研究旨在探讨临床,超声心动图,2016年至2023年期间,我们诊所收治的先天性心脏病患者的MAPCAs的放射学特征。
    使用在双源128层CT扫描仪上进行的胸部计算机断层扫描检查,对46例病例进行了回顾性分析。收集并分析了临床数据和放射学特征。
    这项研究揭示了先天性心脏病与MAPCAs的存在有很强的相关性,TOF,PA,室间隔缺损(VSD)是最常见的,这表明这些络脉可能存在于未诊断的先天性心脏病中。三尖瓣反流和主动脉瓣关闭不全是主要的超声心动图检查结果。放射学上,在85%的病例中,MAPCAs主要起源于降主动脉(II型),它们的尺寸范围从≤3毫米到>10毫米,平均5毫米。
    这项研究为先天性心脏病患者的MAPCAs的临床和放射学方面提供了全面的见解。研究结果强调了早期发现和干预对于更好地管理这些复杂疾病的重要性以及进一步研究的必要性。
    UNASSIGNED: Major aortopulmonary collateral arteries (MAPCAs) are rare congenital anomalies with significant clinical implications, often associated with congenital heart diseases like tetralogy of Fallot (TOF) and pulmonary atresia (PA). This study aimed to investigate the clinical, echocardiographic, and radiologic characteristics of MAPCAs in patients with congenital heart diseases admitted to our clinic between 2016 and 2023.
    UNASSIGNED: A retrospective analysis of 46 cases was conducted using chest computed tomography exams performed on a dual-source 128-slice CT scanner. Clinical data and radiologic characteristics were collected and analysed.
    UNASSIGNED: The study revealed a strong correlation between congenital heart diseases and the presence of MAPCAs, with TOF, PA, and ventricular septal defect (VSD) being the most common, and it indicated that these collaterals may exist with non-diagnosed congenital heart disease. Tricuspid regurgitation and aortic insufficiency were the predominant echocardiographic findings. Radiologically, MAPCAs primarily originated from the descending aorta (type II) in 85% of cases, and their sizes ranged from ≤ 3 mm to > 10 mm, with an average of 5 mm.
    UNASSIGNED: This study provides comprehensive insights into the clinical and radiologic aspects of MAPCAs in patients with congenital heart diseases. The findings emphasise the importance of early detection and intervention for better managing of these complex conditions and the need for further research.

    动脉干(TA,也称为普通动脉干)仅由一条大动脉(“干”)和一个由心脏引起的半月瓣(干瓣膜)和一个额外的室间隔缺损组成(图。50.1).这条大动脉位于室间隔缺损上方,并产生冠状动脉,肺动脉,和主动脉弓.历史上,科莱和爱德华兹将TA分为三种类型,在I型中有一个常见的肺动脉干,在II型中,左PA和右PA分别出现,但彼此靠近,在III型中,两个PA都独立出现;此外,有一种IV型,后来表现为肺动脉闭锁伴VSD,主要主肺侧支动脉起因于降主动脉.
    Truncus arteriosus (TA, also known as common arterial trunk) consists of only one great artery (\"the truncus\") with a semilunar valve (truncus valve) arising from the heart and an additional ventricular septal defect and (Fig. 50.1). This great artery is positioned above the ventricular septal defect and gives rise to the coronary arteries, the pulmonary arteries, and the aortic arch. Historically, TA has been classified by Collet and Edwards in three types, where in type I there was a common pulmonary artery truncus, in type II the left and right PA arise separately but close to each other, in type III both PA arise independently; in addition, there was a type IV that was later characterized as pulmonary atresia with VSD and major aortopulmonary collateral arteries arising from the descending aorta.

    随着胎儿一生中先天性心脏病检出率的提高,胎儿心脏干预措施正在推动发展,希望改变疾病的自然史或提高某些高危病变的生存率。这些干预措施包括胎儿主动脉瓣成形术治疗左心发育不良综合征,胎儿房间隔成形术伴或不伴房间隔支架置入治疗左心发育不良综合征和房间隔完整或严重限制性房间隔变异,和胎儿肺动脉瓣成形术治疗重度肺动脉狭窄或室间隔完整的肺动脉闭锁。这篇综述讨论了他们的适应症,技术方面,和基于现有文献的结果。
    With the improvement in the detection of congenital heart disease in fetal life, fetal cardiac interventions are pushing the envelope in hopes of either altering the natural history of disease or improving survival in certain high-risk lesions. These interventions include fetal aortic valvuloplasty for evolving hypoplastic left heart syndrome, fetal atrial septoplasty with or without atrial septal stenting for hypoplastic left heart syndrome and variants with intact or severely restrictive atrial septum, and fetal pulmonary valvuloplasty for severe pulmonary stenosis or pulmonary atresia with intact ventricular septum. This review discusses their indications, technical aspects, and outcomes based on available literature.

    目标:在我们中心,我们观察到产前诊断为法洛四联症(ToF)的右主动脉弓(RAA)频率增加,动脉导管(ADA)发育不全及其变异。本研究旨在确定胎儿中RAA和ADA是否与ToF相关。进一步评估了遗传异常的分布及其对产后结局的影响。
    方法:单中心回顾性观察研究,包括2010年至2023年产前诊断为ToF的妊娠。所有病例均分为ToF伴肺动脉狭窄(PS)和肺动脉闭锁(PA)。回顾了临床和超声心动图数据库的妊娠结局,遗传异常,和产后课程。
    结果:该队列包括169例,124(73.4%)使用ToF/PS,45(26.6%)使用ToF/PA。与左主动脉弓相比,在ToF的两种亚型(p=0.001)中,动脉导管的分裂与RAA显着相关,在ToF/PS的胎儿中为82.5%(33/40)对10.7%(9/84),在ToF/PA的胎儿中为57.1%(8/14)对12.9%(4/31)。在ToF/PS和ToF/PA中,RAA/ADA与RAA/专利DA显示存在遗传异常的风险明显更高,尤其是微缺失22q11.2,主肺动脉侧支动脉和较短的时间完成手术修复。
    结论:我们证明在产前诊断为ToF的患者中RAA/ADA的频率显著增加。尽管这种关联显示对总生存率没有显著影响,RAA/ADA的产前检测对咨询有影响,遗传评估和产后管理。
    In our center, we observed an increased frequency of right aortic arch (RAA) with an agenesis of the ductus arteriosus (ADA) in prenatally diagnosed tetralogy of Fallot (ToF) and its variations. This study aimed to determine whether there is an association of RAA and ADA in fetuses with ToF. Distribution of genetic anomalies and impact on postnatal outcome were further evaluated.
    Single-center retrospective observational study including pregnancies with prenatal diagnosis of ToF from 2010 to 2023. All cases were subdivided into ToF with pulmonary stenosis (PS) and pulmonary atresia (PA). Clinical and echocardiographic databases were reviewed for pregnancy outcome, genetic anomalies, and postnatal course.
    The cohort included 169 cases, 124 (73.4%) with ToF/PS and 45(26.6%) with ToF/PA. Agenesis of the ductus arteriosus was significantly associated with RAA in both subtypes of ToF (p = 0.001) compared to left aortic arch and found in 82.5% (33/40) versus 10.7% (9/84) of fetuses with ToF/PS and in 57.1% (8/14) versus 12.9% (4/31) of fetuses with ToF/PA. In both ToF/PS and ToF/PA, RAA/ADA versus RAA/patent DA revealed a significantly higher risk for the presence of genetic abnormalities, especially microdeletion 22q11.2, major aorto-pulmonary collateral arteries and a shorter time to complete surgical repair.
    We demonstrated a significantly increased frequency of RAA/ADA in patients with prenatally diagnosed ToF. Although this association revealed no significant impact on overall survival, the prenatal detection of RAA/ADA has implications for counseling, genetic evaluation and postnatal management.

    Brugada综合征是一种罕见的致心律失常综合征,主要与SCN5A基因的致病变异有关。在一些诊断为Brugada综合征的患者中已经报道了右心室流出道纤维化。室间隔完整的肺动脉闭锁的特征是缺乏功能性肺动脉瓣,由于右心室流出道发育不足。我们报告,第一次,一个4岁的男孩,患有肺动脉闭锁,室间隔完整,在SCN5A中具有致病性从头变异,ajmaline测试揭示了1型Brugada模式。我们建议SCN5A基因的有害变异可能与完整的室间隔胚胎发生的肺动脉闭锁有关。导致表型重叠。
    Brugada syndrome is a rare arrhythmogenic syndrome associated mainly with pathogenic variants in the SCN5A gene. Right ventricle outflow tract fibrosis has been reported in some cases of patients diagnosed with Brugada syndrome. Pulmonary atresia with an intact ventricular septum is characterized by the lack of a functional pulmonary valve, due to the underdevelopment of the right ventricle outflow tract. We report, for the first time, a 4-year-old boy with pulmonary atresia with an intact ventricular septum who harbored a pathogenic de novo variant in SCN5A, and the ajmaline test unmasked a type-1 Brugada pattern. We suggest that deleterious variants in the SCN5A gene could be implicated in pulmonary atresia with an intact ventricular septum embryogenesis, leading to overlapping phenotypes.

    Ebstein异常(EA)是一种罕见的先天性心脏病,其特征是三尖瓣(TV)和右心室心肌发育异常。这项研究记录了2例胎儿EA的戏剧性病例,其特征是水肿和心脏肥大,导致宫内或新生儿早期死亡。这些临床结果与形态学异常相关,包括严重的三尖瓣反流,无人看守的电视口,肺动脉闭锁,和扁平的右心室心肌。这项研究强调,这些不利的解剖特征可能会导致胎儿EA的不良临床结局。虽然通过产前超声及时识别这些特征对于提供准确的预后分层和指导治疗决策至关重要。胎儿检查可能需要在右心异常的频谱中辨别EA。
    Ebstein anomaly (EA) is a rare congenital heart defect characterized by abnormal development of the tricuspid valve (TV) and right ventricular myocardium. This study documents 2 dramatic cases of fetal EA characterized by hydrops and cardiomegaly, leading to intrauterine or early neonatal death. These clinical outcomes were associated with morphological abnormalities including severe tricuspid regurgitation, unguarded TV orifice, pulmonary atresia, and flattened right ventricular myocardium. This study highlights that these adverse anatomical features may result in unfavorable clinical outcomes in fetal EA. While timely identification of such features by prenatal ultrasound is crucial for providing accurate prognostic stratification and guiding treatment decisions, fetopsy may be necessary to discern EA among the spectrum of right-heart anomalies.
