Sana

We did not observe any extra cardiac origin of SANA. This finding is similar to Onciu M et al.

James (1961) had described the origin of SANA directly from the aortic sinuses.

According to Anjali Sabnis et al, the mean distance between the origin of SANA and origin of RCA was 35 mm.

Saremi et al found the distance between ostium of LCx and Left SANA ranged from 2 - 35 mm.

Ortale et al reported that the longest distance between the ostium of RCA and origin of SANA from RCA is 48.6 mm.
