Pathomorphology of atherosclerotic coronary artery aneurysms and heart architectonics

Area of Science:

• Cardiovascular Medicine
• Pathology
• Radiology

Background:

• Atherosclerotic aneurysms are increasingly recognized vascular pathologies.
• The anterior interventricular branch of the left coronary artery is a critical vessel.
• Understanding aneurysm morphology and location is vital for diagnosis and treatment.

Purpose of the Study:

• To investigate the incidence and characteristics of atherosclerotic aneurysms in the anterior interventricular branch of the left coronary artery.
• To correlate aneurysm features with coronary artery anatomy and hemodynamics.
• To propose diagnostic criteria for coronary artery aneurysms.

Main Methods:

• Coronary angiography analysis to identify and characterize aneurysms.
• Morphometric analysis of aneurysm size and shape.
• Assessment of cardiac angioarchitectonics and hemodynamic shifts.
• Correlation analysis between aneurysm characteristics and clinical outcomes.

Main Results:

• The first proximal segments of the anterior interventricular branch showed the highest incidence of atherosclerotic aneurysms.
• A positive correlation was found between aneurysm incidence, size, and bag-like shape.
• Aneurysm-dependent alterations in cardiac angioarchitectonics led to significant coronary hemodynamic changes.
• Established criteria for coronarographic diagnostics and correction methods were proposed.

Conclusions:

• The proximal anterior interventricular artery is particularly vulnerable to atherosclerotic aneurysms.
• Aneurysm morphology and location are key diagnostic indicators.
• Coronary artery aneurysms have a significant impact on cardiac hemodynamics and are linked to fatal complications.
