当右冠状动脉占主导地位时，即它走行至心脏的核心时，左冠状动脉回旋支通常相当小，因此可能被认为是发育不全（图1）。相反，当左回旋支是主要的冠状动脉时，即它走行至心脏的核心时，右冠状动脉通常很小，因此可能被认为是发育不全（图1）。然而，同一心脏中左右回旋冠状动脉发育不全的情况很少见（图 1）。过去 8 年对 3,400 颗心脏的检查显示，至少 8 颗心脏的左右回旋冠状动脉均存在发育不全。本文将描述这 8 名患者的某些发现。
When the right coronary artery is dominant, i.e., it courses to the crux of the heart, the left circumflex coronary artery is usually quite small and therefore may be considered hypoplastic (Figure 1). Conversely, when the left circumflex is the dominant coronary artery, i.e., it courses to the crux of the heart, the right coronary artery is usually small and therefore may be considered hypoplastic (Figure 1). Hypoplasia of both right and left circumflex coronary arteries in the same heart, however, is a rare occurrence (Figure 1). Examination of 3,400 hearts during the last 8 years disclosed at least 8 to have hypoplasia plasia of both right and left circumflex coronary arteries. Certain findings in these 8 patients will be described here.
