BACKGROUND
The Right Conus Artery is the first branch of Right Coronary Artery. Sometimes it can arise directly from Aorta, then it is called as Third Coronary Artery. Knowing the angulations of Right Conus Artery will be very helpful to the surgeons during aortic root replacement surgery and re-insertion. The Conus Artery angle changes as a result of growth and morphological changes to the myocardium.
AIM
To find the Angulations of Right Conus Artery.
MATERIALS AND METHODS
150 cadaveric hearts of both male and female with unknown age fixed in 10% formalin were used to study the angulations of Right Conus Artery with manual goniometer.
STATISTICAL ANALYSIS
Students unpaired t test was analysed by SPSS software.
RESULTS AND DISCUSSION
In this study, the P value obtained for angulations of right conus artery with respect to aorta and Right Coronary Artery was less than 0.0001 which shows that there is a significant difference in the angulations of Right Conus Artery depending on whether it is arising from Aorta (Obtuse) or Right Coronary Artery (Acute).The P value obtained for angulations of right conus artery in common origin and when arising from Right Coronary Artery was greater than 0.0001 which shows that there is no significant difference in the angulations of Right Conus Artery depending on whether it is arising from Right Coronary Artery or having a common origin mostly acute. Similar study of angulations has been done by Ivan Stankovic. He reported that the angle between the Third Coronary Artery (TCA) and Aorta is 73.4°±35.2° (Insignificant) and angle between Right Coronary Artery and Right Conus artery is 82.3°±39.8° (insignificant) which differs from our present study.
CONCLUSION
Angulations of Right Conus Artery with Aortic origin was obtuse and with Right Coronary Artery and common origin was acute. This obtuse angulations of Right Conus Artery with Aortic origin that irrigates myocardium is a boon to heart.
