Anomalous Pulmonary Venous Return: Causes, Signs, and Best Management Practices
Anomalous pulmonary venous return (APVR) is a rare congenital heart defect in which one or more pulmonary veins connect abnormally to the right side of the heart or to systemic veins, rather than draining into the left atrium as they should. This misconnection causes oxygen-rich blood from the lungs to flow into the wrong chamber, leading to a mix...
Anomalous Right Coronary Artery: Overview, Diagnosis, Symptoms, and Current Treatments
An anomalous right coronary artery (ARCA) is a rare congenital heart defect in which the right coronary artery arises from an abnormal location, most commonly from the opposite (left) sinus of Valsalva. While many individuals may live symptom-free, certain types of ARCA can put people—especially young athletes—at risk for reduced blood flow, chest pain, or even sudden cardiac events....

Early recognition, risk assessment, and appropriate monitoring are crucial for...
Aortic Insufficiency: Overview, Diagnosis, and Effective Modern Therapies
Aortic insufficiency, sometimes called aortic regurgitation, is a condition in which the aortic valve fails to close tightly, allowing blood to flow backward from the aorta into the left ventricle of the heart. This extra workload can cause the heart to stretch and weaken over time, affecting overall circulation and leading to symptoms ranging from subtle fatigue to severe...
Aortic Regurgitation: Diagnosis, Risk Factors, and Latest Treatment Approaches
Aortic regurgitation is a heart valve disorder in which the aortic valve does not close tightly, allowing blood to leak back into the left ventricle from the aorta after each heartbeat. This backflow increases the heart’s workload and can gradually lead to symptoms such as fatigue, breathlessness, or heart failure if not properly managed. Understanding the causes, risk factors,...
Aortic Root Aneurysm: Comprehensive Guide to Warning Signs, Risk Factors, and Management
Aortic root aneurysm is a serious cardiovascular condition marked by the abnormal bulging or dilation of the aorta at its origin, near where it connects with the heart and aortic valve.

Aortic Valve Regurgitation: Complete Guide to Causes, Signs, and Management Strategies
Aortic valve regurgitation is a heart valve disorder where the aortic valve does not close tightly, allowing blood to leak backward from the aorta into the left ventricle. This can lead to progressive heart strain, symptoms such as fatigue and breathlessness, and—if left unmanaged—potentially serious complications like heart failure. Understanding aortic regurgitation’s causes, risk factors, signs, diagnostic approaches, and...
Aortic Valve Stenosis: Causes, Symptoms, Diagnosis, and Best Treatment Options
Aortic valve stenosis is a common and potentially life-threatening heart valve disorder characterized by the narrowing of the aortic valve opening, which impedes blood flow from the left ventricle into the aorta and onward to the rest of the body.

Aortitis: Comprehensive Overview, Early Signs, Causes, and Therapy Options
Aortitis is a rare but potentially life-threatening inflammation of the aorta, the body's largest artery. This condition can stem from autoimmune disorders, infections, or other underlying diseases, and often develops subtly before leading to serious complications like aneurysms, stenosis, or even rupture. Aortitis can affect people of all ages, but its symptoms may mimic other illnesses, making diagnosis challenging....
Aortocaval Fistula: Causes, Symptoms, Diagnosis, and Surgical Treatment Options
Aortocaval fistula (ACF) is a rare but life-threatening vascular abnormality in which an abnormal connection forms between the aorta and the inferior vena cava, the body’s largest artery and vein.

While some individuals experience chest pain, palpitations, or fainting,...
Apoplexy: Sudden Loss of Function, Warning Signs, Diagnosis, and Modern Treatments
Apoplexy is an ancient medical term historically used to describe a sudden loss of consciousness or bodily function due to the rupture or blockage of a blood vessel, most commonly in the brain. Today, it is most closely associated with what we now call a “stroke,” yet the term also covers hemorrhages in other organs, such as pituitary apoplexy....
