12月20日晚间，宁波大学附属妇女儿童医院（宁波妇儿医院）针对此前心脏手术去世患儿尸检报告 发布情况说明称，尸检报告显示："房间隔缺损大小为1.0cmx0.9cm"，而不是患方所说的0.3cm。 在尸检时，患儿的心脏处于停止状态，较生前充满血及跳动时有大幅度缩小。1cm左右的房间隔缺 损对于5个月患儿的生长发育存在较大的影响。 不过这一情况说明一经发布就被删除了。第一财经记者未能在非工作时段联系到宁波妇儿医院相关科 室作出解释。 12月14日，宁波市卫健委微信公众号"健康宁波"曾发布情况通报，公布了针对11月14日在宁波妇 儿医院接受心脏手术患儿许某某（小洛熙）不幸离世事件的调查进展，从医院党委书记、院长、分管 副院长到主刀医生等多人被处理，主刀医生同时被停诊。 截至目前，这起医疗事故的技术鉴定尚未公布，具体医疗过错及其责任程度也尚未明确，目前的争议 之一是患儿的房缺大小是否有必要做手术。 2025.12. 21 本文字数：1788，阅读时长大约3分钟 作者 | 第一财经 钱童心 目前用于房缺治疗的器械主要分为介入封堵器械和外科手术相关器械材料。选择哪种治疗方案和器械 取决于房缺的类型、大小、位置以及患者的个 ...

Core Viewpoint - The article discusses the medical controversy surrounding a child's heart surgery at Ningbo Women's and Children's Hospital, focusing on the size of the atrial septal defect (ASD) and the implications for surgical intervention [1][2]. Group 1: Medical Context - The child, a premature infant, was diagnosed with two atrial septal defects, which are common in premature infants and may self-resolve; however, larger defects typically require intervention [2]. - Surgical indications for ASD in children are flexible, with larger defects (diameter >8mm) generally requiring intervention due to low chances of self-resolution [2]. - Clinical assessment for surgery considers hemodynamic changes and the presence of symptoms, with early-stage defects often asymptomatic, leading to potential delays in treatment [2][3]. Group 2: Surgical Techniques and Equipment - Treatment for ASD can be performed via minimally invasive techniques or open-heart surgery, with specific indications for each based on the defect's characteristics [3]. - The choice of surgical method and equipment depends on the type, size, and location of the defect, as well as the individual patient's condition [3]. - Surgical materials include autologous pericardium or processed bovine pericardium for repairs, while interventional procedures utilize occluders made from nickel-titanium alloy [3]. Group 3: Epidemiological Data - Recent epidemiological studies indicate that the incidence of congenital heart disease in China ranges from 8‰ to 10‰, with ASD accounting for approximately 10%-15% of all congenital heart defects [4]. - Based on these statistics, the birth prevalence of ASD is estimated to be between 0.8‰ and 1.5‰, translating to about 0.8 to 1.5 cases per 1,000 live births [4].
