Abstract

Background: Single coronary artery (SCA) is a rare anomaly with a prevalence of 0.024-0.066%. Some anomalies are merely benign anatomical variants, whereas some can result in myocardial ischemia or life-threatening arrhythmia. Case Presentation. We described seven cases in which all three major coronaries emerged from the right sinus of Valsalva via a single ostium and supplied the vast majority of the myocardium. A smaller branch arising from the left sinus supplied a modest quantity of myocardium in some of those few cases. These SCA variations do not exactly fit into any existing classification. It is unclear whether we need to modify previous classification systems or newer classification systems.

Conclusions: SCA is divided based on its anomalous course and is usually a benign condition but it may present with cardiovascular complications. Clinicians should be aware of this entity along with the role of CT angiogram in its diagnosis and management.

瓦尔萨尔瓦右窦单根冠状动脉:7例单中心经验。

背景:单冠状动脉(SCA)是一种罕见的异常，患病率为0.024-0.066%。有些异常仅仅是良性的解剖变异，而有些可能导致心肌缺血或危及生命的心律失常。案例演示。我们描述了七个病例，所有三个主要冠状动脉都从右Valsalva窦通过一个口出现，并供应绝大部分心肌。在少数病例中，从左窦产生的一个较小的分支提供了适量的心肌。这些SCA变体并不完全适合任何现有的分类。目前尚不清楚我们是否需要修改以前的分类系统或更新的分类系统。结论:SCA可根据其异常病程划分，通常为良性，但也可能伴有心血管并发症。临床医生应该意识到这一实体以及CT血管造影在其诊断和管理中的作用。
