The authors analyzed cardiac CT scans of 70 patients for the smallest distance between each point on the annulus and each of the left circumflex and right coronary arteries. The global minimum for the left circumflex was <5 mm for about 30% of patients. Knowledge of the exact anatomic relationships could help to reduce iatrogenic complications of mitral annuloplasty.
