The aortic root is at the center of the heart. Each of the aortic sinuses of Valsalva, positioned at the base of the aortic root, is in contact with the atrial myocardium and/or ventricular myocardium at their bases, which enables mapping and ablating of some ventricular arrhythmias with an outflow tract origin and supraventricular tachycardias (ie, atrial tachycardia, accessory pathways) from the aortic sinuses of Valsalva. These arrhythmias have characteristic electrocardiographic findings associated with their origins, and almost all are difficult to ablate from an atrial or ventricular endocardial site. Site-specific and potential complications, such as a coronary artery occlusion or atrioventricular block, can occur with catheter ablation at the aortic sinuses of Valsalva. Therefore, accurate diagnosis and proper ablation at the aortic sinuses of Valsalva are required for a cure. This review describes the anatomic features of the aortic sinuses of Valsalva and focuses on the diagnosis and radiofrequency catheter ablation of arrhythmias that can be ablated from this site.

主动脉根部位于心脏的中心。每个主动脉窦（位于主动脉根部的底部）都与心房心肌和/或心室心肌在其基部接触，这使得可以从主动脉窦对一些起源于流出道的室性心律失常和（例如，房性心动过速、旁路）进行标测和消融。这些心律失常与其起源相关具有特征性的心电图发现，几乎所有心律失常都难以从心房或心室心内膜部位进行消融。在主动脉窦进行导管消融时可能会出现特定部位的并发症和潜在并发症，例如冠状动脉闭塞或房室传导阻滞。因此，需要在主动脉窦进行准确的诊断和适当的消融才能治愈。本综述描述了主动脉窦的解剖特征，并重点介绍了可以从该部位消融的心律失常的诊断和射频导管消融。（Circ J 2012; 76: 791-800）。
