摘要

一名 1 周大的女孩突然意外死亡。尸检的主要发现是右侧优势冠状动脉循环,左侧冠状动脉骨膜不明显。经过仔细检查,发现左冠状动脉的起源异常,其骨膜位于非冠状动脉尖部,紧邻非冠状动脉尖部和左冠状动脉尖部的交界处。动脉管壁口径较小,动脉方向偏斜(见图 1)。

Hidden Coronary Artery Ostium and Sudden Death.

A 1-week-old girl died suddenly and unexpectedly. At autopsy the major finding was of a right dominant coronary artery circulation with an inapparent left coronary artery ostium. After careful examination, an anomalous origin of the left coronary artery was found with the ostium located in the non-coronary cusp immediately adjacent to the commissure of the non- and left coronary cusps. The ostium was of small caliber with an obliquely oriented artery (<45°) with no ostial ridges. The artery coursed anteriorly past the left coronary cusp between the aorta and the left atrial appendage to then follow its usual course inferiorly along the anterior aspect of the left ventricle. The reminder of the autopsy was unremarkable. Death was, therefore, attributed to an anomalous and hypoplastic left coronary artery (and ostium) with an acute angle of take-off. Tracing coronary arteries in the very young may be technically difficult due to their small size, thus identifying the location of ostia is important. This may be difficult when the ostium was located close to a commissure.

期刊介绍: The Journal covers the spectrum of disorders of early development (including embryology, placentology, and teratology), gestational and perinatal diseases, and all diseases of childhood. Studies may be in any field of experimental, anatomic, or clinical pathology, including molecular pathology. Case reports are published only if they provide new insights into disease mechanisms or new information.
