ABSTRACT
To study the variations in gross appearance of ascending aortic fold, and relationship of vertical height of middle of fold to vertical height of heart and to the mean width of the fold. This was a cross sectional study. Department of anatomy, Rawalpindi Medical College, Rawalpindi, from Jan 2010 toDec2010. The present study was carried out on 24 hearts obtained from the dissection room of Rawalpindi Medical College, Rawalpindi. All the cases cadavers available during the study period were included in the study. The ascending aorta was studied with respect to its length and presence of fold in each of the specimens. The direction of the fold was noted forthe classic oblique form and other variations. The fold was present in all the specimens. It was oblique in 13 cases, horizontal in 6, oval in 2, vertical oblique in 2 and vertical horizontal in 1 individual. The vertical height of middle of fold was inversely proportional to vertical height of the heart and directly proportional to the mean width of the fold. The present study provided new dimension and observation that the vertical height of the middle of fold and vertical height of heart are inversely proportional to each other. Vertical height of the middle of fold and mean width of the fold are directly proportional to each other
