Insights
This study demonstrates coronary artery collaterals using coronary angiography and injection-corrosion methods. Coronary angiography is a valuable tool for visualizing these vital blood vessel pathways.
Area of Science:
- Cardiovascular Anatomy
- Interventional Cardiology
Background:
- Coronary artery disease necessitates understanding collateral circulation.
- Collateral pathways are crucial for myocardial perfusion during occlusive events.
Purpose of the Study:
- To illustrate diverse coronary artery collateral types.
- To evaluate coronary angiography and injection-corrosion methods for collateral visualization.
Main Methods:
- Utilized 30 human cadaveric hearts for anatomical study.
- Analyzed 30 patient coronary angiograms (retrospective and prospective).
- Employed coronary angiography and injection-corrosion techniques.
Main Results:
- Identified both intercoronary and intracoronary collateral types.
- Observed well-developed collaterals in cases of right and left coronary artery occlusion.
- Classified patients into groups based on collateral status and left ventricular function.
Conclusions:
- Coronary angiography effectively demonstrates coronary collaterals.
- Anatomical and clinical investigations confirm the presence of various collateral types.
- Understanding collaterals aids in assessing cardiac function in disease states.
Abstract:
The aim of the investigations was to demonstrate different types of collaterals of coronary arteries using the method of coronary angiography and injection-corrosion method. The investigations were carried out on 30 human cadaveric hearts from the Department of Anatomy, and 30 angiograms of patients from the Cardiology Department of Clinics Centre in Sarajevo. Clinical investigations were retrospective and prospective on patients that were treated in hospital, and on patients that just arrived in hospital (based on findings of coronary angiography). The results show the existence of different types of collaterals: intercoronary and intracoronary. We established collaterals in a case with occlusion of the right coronary artery and left coronary artery in which better development of collaterals was established. Our patients were classified in two groups: 1) Patients with good collaterals and good left ventricular function; 2) Patients with good collaterals and impaired left ventricular function. On the anatomical material we found different types of collaterals as well. Our results show that coronary angiography is useful diagnostic method for the demonstration of coronary collaterals.

01:21Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

01:11Overview of Systemic Arteries
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the heart.
01:14Overview of the Cardiovascular System
Heart
The heart is the central pump of the cardiovascular system that circulates blood throughout the body. It comprises two atria receiving the blood and two ventricles pumping blood out of the heart. Their rhythmic contractions, called heartbeats, ensure that blood flow remains continuous.

Diastole: The Relaxation Phase
During diastole, all four heart chambers relax. The atrioventricular (AV) valves open, and the semilunar valves close. This phase sees the lowest chamber pressures, promoting ventricular filling. Venous blood enters the heart through the...
