Background: Incidence of the heart disease increases day by day in Bangladesh. Recent advances in cardiac surgery and the search for new techniques toward investigation of the heart are demanding a review of the anatomy of the coronary arteries. Method: The present study was performed on sixty (60) adult postmortem human hearts of Bangladeshi people. The samples were divided into 3 age groups: Group A (20 to 40 years) consists of 35 male & 7 female samples, Group B (41 to 60 years) consists of 3 female samples and Group C (61 to 75 years) consists of 7 male samples. Results: In the present study, dominance pattern of the coronary artery was right for male in-group A, B, C were 32 (91.4%), 7(87.5%), 6(85.7%), respectively and for female were 6 (85.7%). 3 (100%) respectively. It was left for male in-group A, B, C were 3 (8.6%), 1 (12.5%), 1(14.3%), respectively and for female was 1 (14.3%). Conclusion: The results of the present study can be helpful to the cardiologists and cardiovasc...

The study was undertaken to assess the coronary dominance and variations in luminal diameters of major coronary arteries and to compare the relation between the coronary dominance and variation in luminal diameter and between coronary dominance and number of vessels measuring less than 2.5 mm in diameter, in 75 cadaveric human hearts obtained from the Department of Anatomy from the various medical colleges of western Maharashtra, India. Out of 75 hearts, 58 (77.33%) showed right dominance, 14 (18.67%) showed left dominance and 3 (4%) showed codominant pattern. No significant difference was noted in the luminal diameters of coronary arteries (right coronary artery, marginal artery, posterior interventricular artery, left coronary artery, anterior interventricular branch, circumflex branch) among the dominance type. It was also observed that 63 hearts (84%) showed more than 2 arteries measuring less than 2.5mm in diameter. To conclude, a majority of the population has a right predomin...
An Anatomical Study on the Coronary Arteries and Their Variations
International Journal of Anatomy and Research, 2016
Background and Aims: The term "Coronary" is derived from the Latin word "Corona", which means crown. The rise in the coronary heart disease in India has led to a rapid transition in health status.The present study is conducted to observe the origin, branching pattern and termination of the coronary arteries in human cadaveric hearts. Preponderance of right coronary dominance or left coronary dominance is also looked for in this study. Materials and Methods: 50 human hearts were collected from the embalmed cadavers of both the sexes, from the department of Anatomy of our institution. They were preserved in 10% formalin. Observation: In the present study, right coronary dominance is observed in 84% and left coronary dominance is observed in 16% of specimens. In 2% of specimen, third coronary artery is observed. 4% of short trunk (< 5 mm) and 6% of long trunk (> 15 mm) of left main coronary artery is observed. The average length of left main coronary trunk is 9.34 mm. In 14% of specimens, myocardial bridges are observed. Conclusion: Knowledge of normal anatomy of coronary arteries, its variations and anomalies related to coronary circulation is mandatory for good clinical outcome following therapeutic procedures, like angioplasty and coronary artery bypass grafting. Thus in the interest of this subject, this study is pursued.

Introduction: Cardiac coronary dominance plays a significant role in different clinical conditions and diseases of the heart. As the people of developing and developed nations are having global coronary artery diseases, it is mandatory to have knowledge of coronary artery diseases including cardiac coronary dominance. The aim of this study is to find out the prevalence of the right coronary artery dominance in cadaveric human hearts in a medical college. Methods: A descriptive cross-sectional study was conducted among all 52 preserved hearts as well as the heart isolated from cadavers obtained from the teaching hospital. The study was conducted from 24th June, 2020 to 24th December, 2020 after obtaining ethical clearance from the Institutional Review Committee (Reference number: 2306202004). All cadaveric heart specimens were laelled with numbers and photographed for easy description of anatomical variation related to the coronary artery. Data were entered into Microsoft Excel 2007 ...
Coronary artery dimensions in the Nepalese population
Journal of the Anatomical Society of India, 2015
Introduction: This study is an attempt to document normal dimensions of the coronary artery branches during life by using quantitative coronary angiography and compare them with international studies. Method: Quantitative coronary angiography (QCA) of 100 patients undergoing evaluation of ischemic heart disease but found to be free of coronary artery disease. Measurement was done using catheter tip as a calibrating object. Results: Out of 57% right dominant circulation 56.1% were of males and 44% of females. Left coronary dominance was seen in 17% of which 52.9% were male and 47% female, by contrast 26% subjects had co-dominant hearts with 61.5% male and 38.4% female. The mean diameter of the right coronary artery was significantly smaller (p < 0.05) in left dominant hearts as compared to that of dominant right. In contrast the mean diameter of the circumflex artery was significantly smaller (p < 0.05) in right dominant pattern as compared to that of patients with dominant left. Similarly the diameter of circumflex artery was significantly smaller in case of codominant type of circulation when compared to that of left coronary pattern of dominancy. Discussion: The distribution pattern of coronary artery in the Nepalese population is distinct from that specified in the literature and the diameters of right coronary artery and circumflex artery are significantly influenced by the nature of dominance.
Assessment of Coronary Artery Dominance in the Indian Cadavers
International Journal of Medical and Biomedical Studies, 2018
As Coronary artery disease is one of the most common heart diseases and also the major cause of death in developing countries. The aim of the present study is to evaluate the coronary dominance pattern which will help the cardiac physicians and surgeons for better diagnosis and management of coronary artery diseases. The study was planned on 30 heart subjects. These selected hearts are without any obvious pathology referred with cardiac conditions was enrolled into the study in Andaman and Nicobar Islands Institute of Medical Science (ANIIMS) from July 2016 to July 2017.The coronary arteries were dissected and analysed for the origin of sinoatrial Nodal artery and Observations were noted. The approval of the Institutional ethical committee was taken for the present study. The hearts identified with the congenital anomalies were excluded from study. From the above study it can be concluded that the most common is the right coronary dominance compared to left and balanced dominance as seen in this study. The present study is in comparison with the data generated by previous authors. This knowledge of normal anatomy and variations of coronary dominance will help interventional cardiologist, cardio-thoracic surgeons and radiologist to plan and provide proper management to patients.

An Autopsy Study of the Quantitative Anatomy of Human Heart
Journal of Advances in Medicine and Medical Research, 2021
There is no uniformity in obtaining anthropological measurements of the heart. Measurements vary according to the methods used by different authors. The normality standard for organ weights should be established in a specific reference sample for each population, as the normality values can be different under genetic and environmental influences. This study is aimed to determine the average values of quantitative anatomy of the adult heart for the Sri Lanka population using autopsy data with an attempt to determine the relationship with sociodemographic factors such as the body weight, age, gender and the body length. Designed as a descriptive cross-sectional prospective study, it was performed on fresh (unfixed) adult hearts recovered at medico-legal autopsy on deaths due to non-cardiac natural causes and miscellaneous unnatural causes for a period of one year. Systematic consecutive sampling method was used from September 2018 to September 2019. Only 122 samples (68 males and 54 females) were included from among 282 adult hearts collected during this period due to strict inclusion and exclusion criteria. Average weight of the heart, thicknesses of the inter-ventricular septum, free wall of the left ventricle and right ventricle for males and females were 296.1 g, 236.85 g, 9.71 mm, 9.52 mm, 1.28 cm, 1.19 cm and 3.41mm, 3.02mm respectively. Male heart weight, interventricular septal thickness and other findings were compatible with contemporary Eastern studies. Significant association was demonstrated in the wall thickness of right ventricle with gender (P- value being 0.038). Large scales multi centered studies to find out the normality standard for heart measurements in Sri Lankan population are recommended.
Anatomical Risk Factors Of Coronary Heart Disease
Medical Journal of Trakya University, 2009
The aim of this study was to explore the possible anatomical risk factors of coronary heart disease (CHD) such as vascular geometry of the left coronary artery and its branches using coronary angiography. Patients and Methods: The trunk length (T) of the left coronary artery, the curve angle of the left anterior descending artery (LAD) and the bifurcation angle between the LAD and the circumflex artery (Cx) were measured in 77 patients (age range 20-83, mean 58.9±11.68). Results: The atherosclerotic plaque existence was investigated in LAD and Cx. The mean values of the T length, LAD curve angle and the LAD-Cx bifurcation angle were respectively 12.86 mm, 140.99° and 94.07°. In patients who have atherosclerotic plaques in LAD, the mean value of the T lengths was found 2.5 mm shorter than those of the patients whose LADs are intact (p=0.020). On the other hand a significant negative correlation between the LAD curve angle and the bifurcation angle was found (p<0.001). Conclusion: In view of our results it can be suggested that geometrical pattern of LAD and its branches may be a congenital risk factor in development of CHD in patients who have no other risk factors.
