6 / BRIEF RESUME OF THE INTENDED WORK:
6.1  Need for the study:
The coronary arteries have some features which distinguish them from the medium sized arteries, both in health and diseases.
The Coronary arteries may present several anomalies in terms of both number and position. An anomalous origin and proximal course of the coronary arteries may be associated with myocardial infarction and sudden death.
Thus the knowledge of normal and variant anatomy of coronay circulation is an increasingly vital component in the management of congenital and acquired heart diseases. Many congenital, inflammatory, metabolic and degenerative diseases may involve the coronary circulation. Increasingly complex cardiac surgical repairs demand the understanding the basic anatomy to improve the operative outcomes.
The recent introduction of selective coronary arteriography provides an accurate localization of the anatomical variations and underlying pathology. The advance made in coronary arterial bypass surgeries and modern methods of mycordial revascularisation demands thorough, sound and complex knowledge of the normal and variant anatomy of coronary artery and circulation. With this aim the coronary arteries are studied with reference to the branching patterns and variations.
6.2  Review of literature:
1.  Edward Jenner (1799) established the understanding of the relationship of coronary artery obstructive disease to angina pectoris and mycordial ischaemia.
2.  W. Henry Hollinshead (1956) described right coronary artery is that which arises from right anterior aortic sinus. Left coronary arises from left posterior aortic sinus. According to him right coronary artery is the dominant artery in majority of the cases.
3.  According to James (1961) Right and left coronary arteries supply the sino-atrial node in 55% and 45% respectively. For atrioventicular node it is 90% and 10% respectively.
4.  S.N. Sahana (1962) described coronary arteries are those which supply the musculature of the heart, the visceral pericardium and the roots of the ascending aorta and pulmonary trunk. Right coronary artery is the dominant artery.
5.  Rene Favaloro and Dudley Johnson (1968) performed 1st coronary bypass surgery and created further interest in coronary anatomy.
6.  From Hutchison’s results (1978) it is apparent that is over 50% of the right atrium is supplied only by the right coronary, the rest receiving a dual supply. More than 62% of left atria are largely supplied by the left and about 27% by the right coronary artery. 11% being supplied by the both.
7.  American Heart Journal (1989) Paolo Angelini, M.D. Houston : Teras. Normal and anomalous coronary arteries : Definition and classification.
8.  Peter L Williams (1995) described right coronary artery as that which arises from anterior aortic sinus and left coronary artery as that which arises from the posterior aortic sinus. Righ coronary artery is the dominant artery in majority of the cases.
9.  Inderbir Sigh (2002) stated that right coronary is the dominant artery in 85% of the cases.

MATERIALS AND METHODS

7.1 Source of data
For the prospective study of two years duration from Jan 2008 to Dec 2009. (40) specimens shall be brought from the unclaimed post mortem bodies in the Department of Forensic Medicine, VIMS, Bellary and (10) from the dissected cadavers in Anatomy Department , VIMS, Bellary.
7.2 Method of collection
After opening the thorax in the postmortem bodies (age and sex noted) in the department of Forensic Medicine, VIMS, Bellary. the pericardial sac is opened to expose the heart. The heart with proximal part of great vessels is identified, dissected & taken out. After cleaning, the specimens are kept in 10% formalin. Later on specimens are studied by dissection method.
7.3 Does the study require any investigation and intervention to be conducted on patients or other humans or animal? If so, describe briefly.
No.
Utmost care will be taken to treat the cadavers with due to respect human body. The organ collected will not be used for any other purpose except for my study.
7.4 Has ethical clearance been obtained from the Institution in case of 7.3?
Yes, Ethical clearance has been obtained fro I.E.C. of VIMS, Bellary.
