A Study of Variations in Human Ascending Aortic Fold

Amer Qayum, Tahzeeb ul Hassan, Tassaduq Hussain.


Objective: 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.
Study Design: This was a cross sectional study.
Place and Duration of Study: Department of anatomy, Rawalpindi Medical College, Rawalpindi, from Jan 2010 to Dec 2010.
Materials and Methods: 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 for the classic oblique form and other variations.
Results: 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.
Conclusion: 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.

Key words: Ascending Aortic fold, Vertical height of heart, Mean width of aortic fold.
