Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

1.6K
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

578
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Coronary Artery Disease II: Pathophysiology

805
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

629
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Rheumatic Heart Disease I: Introduction

625
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

451
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Area of Science:

  • Cardiovascular Medicine
  • Rheumatology
  • Vascular Biology

Background:

  • Takayasu arteritis is a chronic inflammatory large-vessel vasculitis.
  • It commonly leads to arterial stenosis and pulselessness.
  • Aortic calcification is typically minor and not a primary cause of stenosis in this condition.

Purpose of the Study:

  • To report an exceptionally rare case of Takayasu arteritis with extensive and rapidly progressive aortic calcification.
  • To discuss the implications of severe calcification leading to malperfusion in the context of Takayasu arteritis.

Main Methods:

  • Case report detailing clinical presentation, diagnostic imaging, and management.
  • Review of existing literature on aortic calcification in vasculitis.

Main Results:

  • The patient presented with extensive, rapidly progressive aortic calcification.
  • This calcification resulted in significant malperfusion, a rare complication of Takayasu arteritis.
  • The findings challenge the typical understanding of calcification's role in this disease.

Conclusions:

  • Extensive aortic calcification can occur in Takayasu arteritis, leading to severe complications like malperfusion.
  • This case underscores the need to consider unusual presentations and potential calcium dysregulation in chronic inflammatory states.
  • Further research into the mechanisms of calcification in Takayasu arteritis is warranted.
