Updates to Case Attributes

Status changed from pending review to published (public).
Published At was set to .
Body was changed:

An anomalous origin of LCX from right coronary sinus is the most common congenital variant and is divided into three types II:

- Type I: Separate ostia for right coronary artery (RCA) and LCX.

- Type II: Common ostia in the right sinus.

- Type III: LCX arising as a branch of the proximal RCA.

These patients may develop coronary symptoms due to kinking/compression in their retroaortic course.

Updates to Study Attributes

Findings was changed:

Anomalous origin and course of LCX / Typeleft circumflex artery (type III :LCX origins): LCX originates from proximal right coronary RCA (just next yoto RCA origin from right coronary sinus), then LCX has a retro-aortic course, passing between the aorta and left atrium. It is non-dominant and patent with no evidence of plaque or stenosis.
