AVC in Medical Terminology: Multiple Meanings and Contexts
Arrhythmogenic Ventricular Cardiomyopathy (AVC) in Cardiology
In cardiology, AVC most commonly stands for Arrhythmogenic Ventricular Cardiomyopathy. This is an inherited heart muscle disease that can affect both the right and left ventricles, not just the right side as previously thought. Patients with AVC are at risk for sudden cardiac death, ventricular arrhythmias, and heart failure. The condition is linked to genetic mutations affecting proteins in the heart's intercalated disks, which reduces the heart's electrical and mechanical stability. Diagnosis involves a combination of imaging, biopsy, ECG findings, arrhythmia history, and family genetic background. Treatment includes lifestyle changes, medications like beta-blockers, and sometimes implantable devices or ablation procedures. Lifelong monitoring is recommended for both symptomatic patients and those who carry the genetic mutation but have no symptoms yet 12.
Arterial Ventricular Coupling (AVC) in Cardiovascular Physiology
AVC can also refer to Arterial Ventricular Coupling, which describes the relationship between the heart's pumping ability and the resistance of the blood vessels. This parameter is important for understanding how well the heart and blood vessels work together, especially in critically ill patients. Evaluating AVC can provide valuable information about cardiovascular function and help guide treatment decisions in intensive care settings .
Atrioventricular Canal Defects (AVC) in Congenital Heart Disease
In pediatric cardiology, AVC may mean Atrioventricular Canal Defects. These are congenital heart defects involving holes in the walls between the heart's chambers and abnormalities of the heart valves. AVC defects cause mixing of oxygen-rich and oxygen-poor blood inside the heart, which can affect oxygen delivery to the body. They are often associated with other heart or body abnormalities. Diagnosis requires detailed imaging and evaluation, and surgical repair is usually successful with low mortality and good long-term outcomes .
Aortosternal Venous Compression (AVC) in Vascular Medicine
AVC can also stand for Aortosternal Venous Compression, a rare condition where the brachiocephalic vein is compressed between the sternum and the aorta. This can cause changes in blood flow that are visible on imaging, especially during breathing. Diagnosis is confirmed with specialized imaging techniques, and the condition may be related to anatomical variations such as an aberrant right subclavian artery .
Conclusion
In medical terminology, "AVC" can refer to several different conditions depending on the context: Arrhythmogenic Ventricular Cardiomyopathy, Arterial Ventricular Coupling, Atrioventricular Canal Defects, or Aortosternal Venous Compression. Each meaning is specific to a different area of medicine, so it is important to consider the clinical context to understand what AVC refers to in any given situation 12345.
