“…In the present study, the range of RCA-I (34.4-128.8 mm), RCA-II (6.2-43.4 mm), and RCA-III (9.6-69 mm) were recorded in 60 heart specimens. The range of 1 st segment was similar to the study done by Nguyen (32-127.8 mm) [3] and segments 2 nd and (5-10 mm, 7.5±2.7 mm) [10] and was observed lesser than Reddy (15-25 mm, 20±2.65 mm) [2]. The study findings were analogous to Kumar (2-16 mm, 10.2±3.5 mm) [8].…”

“…With the advancement of medical technology, the incidence of coronary angiography and coronary bypass surgeries, stunt, and balloon angioplasty is also increasing. The present study was done with the hope that the data analyzed in the study may help clinicians to interpret properly the findings which will lead to its remedy [2]. In the present study, the range of RCA-I (34.4-128.8 mm), RCA-II (6.2-43.4 mm), and RCA-III (9.6-69 mm) were recorded in 60 heart specimens.…”

“…The normal and variations in the anatomy of the coronary arteries have been studied for a long time, utilizing cadaveric dissection and various medical imaging techniques. Some of the benefits of cadaveric studies are that they are typically more simplistic because the coronary arteries can be studied in a 3D structure and can be followed from their origin or termination [2].…”

Objective: The present study aimed to record the length of coronary arteries was carried out for better anatomical knowledge about the branches of coronary arteries and its variation is essential for cardiologists and interpretation of coronary angiograms by radiologists. Methods: The study group was comprised 60 human cadaveric hearts retrieved from the dead bodies of the age group 18–50 years brought for medicolegal autopsy. Results: In 60 heart specimen’s length of right coronary artery (RCA)-I (34.4–128.8 mm, 81.5±18.1), RCA-II (6.2–43.4 mm, 20.3±9.9), RCA-III (9.6–69 mm, 38.2±18.7), length of left coronary artery (3.4–19 mm, 12.6±3.74 mm), length of left circumflex artery (31.9–144.5 mm, 79.2±26.2 mm), and length of left anterior descending artery (33.4–154.4 mm, 105.3±27 mm). Conclusion: The name and nature of a coronary artery or a branch define that vessel’s vascularization pattern or territory, rather than its origin. Better anatomical knowledge about the branches of the coronary artery and its variation is essential for cardiologists and interpretation of coronary angiograms by radiologists.

“…Fox et al, 15 found the length of LCA to be <6mm in 36% of all specimens while >20mm in 5% of all specimens on cine angiofilms. Reddy & Pusala 16 reported, the left main (LM) coronary artery ranges in length from 1 to 25mm before bifurcating into the LAD and CA. The LAD coronary artery measures from 10 to 13cm in length, whereas the CA artery measures about 6 to 8 cm in length.…”

Background: Coronary arteries play an important role in perfusion of the heart tissues. Variations or anomalies in coronary arteries may be asymptomatic while some can be symptomatic and even cause sudden death. Knowledge of coronary artery variations is important in diagnosis and treatment of cardiovascular diseases. Aim: To describe variation of left coronary artery. Materials and methods: We dissected and grossly examined a total of 78 human hearts to describe coronary artery variations in origin and course. Results and discussion: The mean outer diameter of left coronary artery (LCA), left anterior descending (LAD) and circumflex artery (CA) was 4.34±2.01mm, 4.21±0.28mm, and 2.73±0.6mm respectively. Whereas the mean length of LCA, LAD and CA was 10.2±3.5mm, 83.4±17.8mm, and 44.6±17.9mm respectively. The main trunk of LCA bifurcated in 63 specimens (80.76%), trifurcated in 8 specimens (10.25%), quadrifurcated in 6 specimens (7.69%) and pentafurcated in 1 specimens (1.28%). Conclusion: Knowledge of the normal and variant anatomy of coronary arteries is indispensable and imperative both in diagnosis, treatment and implementation of interventional measures.

“…In the literature, this variability is observed in the range between 3% and 20% (Table). [1][2][3][4][5][6][7] According to other authors, the incidence of multiple PDAs may be higher than 20%. Singha and Konar reported the presence of a single PDA in 74% and multiple PDAs in 26%, but it should be noted that the PDA origin in this analysis was not only from the right coronary artery.…”

Double Posterior Descending Artery Arising from a Right Coronary Artery

This paper presents two cases of human hearts (a 75-year-old woman and an 88-year-old man) with double posterior descending arteries (PDA) of various sizes originating from the right coronary artery, mainly supplying the interventricular septum as well as the posterior walls of both heart ventricles in a different scope. In the analysis of the arterial vasculature, a range of aspects were considered, such as the point of exit of the right coronary artery, the course of the vessel, the range of the blood supply of the interventricular septum and both ventricles, as well as selected morphometric parameters that were simultaneously compared with one another. These atypical changes presented based on the example of the analyzed cases will certainly constitute a valuable source of information for cardiac surgeons and interventional cardiologists in planning operations.
