Abstract
Hypoplastic coronary artery disease (HCAD) is a rare coronary artery anomaly that may be the cause of sudden death. It can involve a single or all coronary arteries. This anomaly may cause circulatory insufficiency leading to myocardial infarction. HCAD has no symptoms or may exhibit cardiovascular signs like syncope, dyspnea, chest discomfort, or dizziness. It is often diagnosed at autopsy, and early diagnosis is made with a coronary angiogram. We report HCAD as the cause of the sudden death of a 25-year-old female with a history of loss of consciousness following exertion. On autopsy, all the coronary arteries' lumen was narrowed with thin vessel walls. Histopathological examination shows an underdeveloped and missing muscular layer of the left anterior descending and circumflex coronary arteries' vascular wall. Many cases of HCAD diagnosed by radiographic imaging in living patients have been reported in the literature, but a structural anomaly of coronaries leading to HCAD has not been reported. We report a case of HCAD describing the histopathological examination findings of the vascular wall of coronary vessels illustrating the structural difference.

Sudden cardiac death related to left coronary artery anomalies including hypoplasia and anomalous origin with retro-aortic course. Leg Med (Tokyo) 2023; 61:102186.

Abstract
Congenital anomalies of the coronary arteries are a rare condition with an incidence of 0.3-1.3% in the general population. Clinically, sometimes these anomalies increase the risk of myocardial ischemia, which can present with a wide spectrum of symptoms, from angina to sudden cardiac death (SCD). This case report is about the SCD of an 8-year-old male, in apparent good health, during a football training. Although basic life support maneuvers were performed timely from bystanders and medical staff, the automated external defibrillator (AED) was not used. Autopsy revealed multiple left coronary artery (LCA) anomalies: origin from a separate ostium in the right sinus of Valsalva, slit-like shape of the ostium, acute angle take-off of the LCA from the aorta, retro-aortic course and focal coronary hypoplasia of some branches of the LCA. Microscopic examination revealed diffuse ischemic consequences at a different stage of tissue repair and mild multifocal lymphocytic infiltration. No other significant elements were detected at post-mortem examination. We discuss the forensic evaluation about the cause and the manner of death, considering also the modality of the resuscitation attempts and the claimed malpractice, as often occurs in case of sudden unexpected death in young athletes.

Abstract
Congenital coronary artery anomalies are estimated to affect about 1% of the general population. Hypoplastic coronary artery disease is an uncommon subset associated with significant mortality regardless whether another major cardiac anomaly is present. In this case report, we present an extremely rare case of an infant with hypoplastic coronary artery disease and hypoplastic pulmonary veins. A literature review pertinent to the clinical findings is also contained herein.

Abstract
A 21-year-old African American male presented to the emergency department after an episode of unexplained syncope. He had no significant past medical history. The initial physical examination was within normal limits, and his 12-lead electrocardiogram showed no signs of ischemia or evidence of chamber enlargement. The patient received a transthoracic echocardiogram which demonstrated mild global left ventricular dysfunction with an estimated ejection fraction of 45%. Coronary angiography was next performed and found no evidence of atherosclerotic coronary artery disease but did reveal hypoplasia of the left circumflex and right coronary arteries, with intraluminal diameters of approximately 1 mm. The left anterior descending coronary artery was small distally. Cardiac magnetic resonance imaging with gadolinium enhancement found no evidence of myocardial scar. The patient was ultimately diagnosed with aborted sudden cardiac death due to hypoplastic coronary artery disease (HCAD). The patient received an implantable cardioverter-defibrillator (ICD) prior to hospital discharge for secondary prevention of sudden cardiac death. One year after this presentation, the patient has been asymptomatic, with no ICD discharges.

Abstract
Despite advances in the management of congenital heart disease (CHD), children with CHD who survive into adulthood are at increased risk of sudden death. Sudden death may also be the initial presentation of undiagnosed CHD in some adults. This retrospective descriptive study outlines the spectrum of CHD presenting as sudden death in adults in a medical examiner's population. Despite its rarity (0.2% of all cases investigated between 1991 and 2007), CHD remains an important cause of sudden cardiac death to be recognized at adult autopsy. Bicuspid aortic valve and anomalous coronary anomalies were the most common malformations, comprising 36.9% and 26.2% of cases, respectively. However, a wide spectrum of simple to complex malformations can be seen, with or without prior surgery, and over a wide age spectrum. Once solely a pediatric entity, CHD is now "grown-up" and will likely be diagnosed by forensic pathologists with increased frequency in the future.

Abstract
Congenital coronary anomalies represent a condition often unrecognized in the living and in the dead. Investigating this condition is relevant for both clinicians and pathologists in order to identify potentially unrecognized coronary causes of sudden death. Hypoplastic coronary artery disease (HCAD) is a rare congenital abnormality reported to be associated with sudden death. We report two additional cases of previously apparently healthy people who died suddenly and were found to have HCAD at postmortem evaluation. The clinicopathologic findings are discussed along with a review of the literature.

Abstract
Congenital underdevelopment of one or more main branches of the coronary arteries has been reported in man, but not in non-human mammals. In man, this defective coronary artery arrangement may cause myocardial ischaemia and even sudden death. The main goal of this study was to describe the coronary artery distribution patterns associated with the presence of a markedly underdeveloped (rudimentary) coronary artery in Syrian hamsters. Moreover, an attempt was made to explain the morphogenesis of these patterns, according to current knowledge on coronary artery development. Eleven affected hamsters belonging to a laboratory inbred family were examined by means of internal casts of the heart, great arterial trunks and coronary arteries. The aortic valve was tricuspid (normal) in seven hamsters and bicuspid in the other four. A rudimentary coronary artery arose from the right side of the aortic valve in four specimens, from the left side of the aortic valve in a further three, and from the dorsal aortic sinus in the remaining four. In all cases, a second, well-developed coronary artery provided for all the coronary blood flow. Except for the existence of a rudimentary coronary artery, the present anomalous coronary artery distribution patterns are similar to coronary artery patterns reported in Syrian hamsters, dogs and humans in association with a solitary coronary ostium in aorta. We suggest that an unusual prolonged time interval in the development of the embryonic coronary stems might be a key factor in the formation of coronary arteries displaying significantly dissimilar developmental degrees.

Abstract
Determining whether hypoplasia of a coronary artery has caused or contributed to death is often complicated by an absence of histologic evidence of myocardial ischemia in the area of the heart supplied by the affected artery and also by the lack of data for assessing coronary artery size at autopsy. A 45-year-old woman is reported who collapsed and died and who was found at autopsy to have a dominant, small-caliber, right coronary artery, with acute and chronic ischemic changes in the posterior interventricular septum supplied by the diminutive vessel. This case provides evidence that small-caliber coronary arteries may be associated with a lethal outcome. Given the difficulties that may occur in determining whether there is a causal link between small coronary artery caliber and death, it is possible that this may be an underdiagnosed cause of sudden cardiac death, rather than a coincidental finding of minimal significance.
