Findings

No curated finding names malposition of the coronary ostium yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

Malposition of the coronary ostium is a rare coronary artery congenital malformation characterized by displacement of one of the coronary arteries, originating closer to the aortic root or to the commissural area. The anomaly is considered to be asymptomatic, however, it may impose surgical difficulties during aortic root surgery.
