Although antenatal diagnostic technique has considerably improved, precise detection and proper management of the neonate with congenital heart disease (CHD) is always a great concern to pediatricians. Congenital cardiac malformations vary from benign to serious conditions such as complete transposition of the great arteries (TGA), critical pulmonary and aortic valvular stenosis/atresia, hypoplastic left heart syndrome (HLHS), obstructed total anomalous pulmonary venous return (TAPVR), which the baby needs immediate diagnosis and management for survival. Unfortunately, these life threatening heart diseases may not have obvious evidence early after birth, most of the clinical and physical findings are nonspecific and vague, which makes the diagnosis difficult. High index of suspicion and astute acumen are essential to decision making. When patent ductus arteriosus (PDA) is opened widely, many serious malformations may not be noticed easily in the early life, but would progress as severe acidosis/shock/cyanosis or even death as PDA constricts after few hours to days. Ductus dependent congenital cardiac lesions can be divided into the ductus dependent systemic or pulmonary disease, but physiologically quite different from each other and treatment strategy has to be tailored to the clinical status and cardiac malformations. Inevitably early presentation is often regarded as a medical emergency. Differential diagnosis with inborn error metabolic disorders, neonatal sepsis, persistent pulmonary hypertension of the newborn (PPHN) and other pulmonary conditions are necessary. Urgent identification of the newborn at such high risk requires timely referral to a pediatric cardiologist, and timely intervention is the key in reducing mortality and morbidity. This following review deals with the clinical presentations, investigative modalities and approach to management of congenital cardiac malformations presenting in the early life.
尽管产前诊断技术有了显著提高,但先天性心脏病(CHD)新生儿的精确检测和妥善管理一直是儿科医生极为关注的问题。先天性心脏畸形从良性到严重情况各不相同,如大动脉完全转位(TGA)、严重的肺动脉和主动脉瓣狭窄/闭锁、左心发育不全综合征(HLHS)、梗阻性完全性肺静脉异位引流(TAPVR),患儿需要立即诊断和治疗才能存活。不幸的是,这些危及生命的心脏病在出生后早期可能没有明显迹象,大多数临床和体格检查结果是非特异性且模糊的,这使得诊断困难。高度的怀疑指数和敏锐的洞察力对于决策至关重要。当动脉导管未闭(PDA)广泛开放时,许多严重畸形在生命早期可能不易被察觉,但在数小时至数天后随着PDA收缩,可能会进展为严重酸中毒/休克/青紫甚至死亡。依赖动脉导管的先天性心脏病变可分为依赖动脉导管的体循环或肺循环疾病,但在生理上彼此差异很大,治疗策略必须根据临床状况和心脏畸形进行调整。不可避免地,早期表现往往被视为医疗急症。与先天性代谢紊乱、新生儿败血症、新生儿持续性肺动脉高压(PPHN)和其他肺部疾病进行鉴别诊断是必要的。对这类高危新生儿进行紧急识别需要及时转诊给儿科心脏病专家,及时干预是降低死亡率和发病率的关键。以下综述探讨了生命早期出现的先天性心脏畸形的临床表现、检查方法和管理方法。
