Insights

Woven coronary artery, a rare condition, is challenging to diagnose. Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) confirm diagnosis, aiding in avoiding unnecessary interventions.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Diagnostic Imaging

Background:

  • Woven coronary artery is an exceedingly rare condition with an unknown cause.
  • Traditional diagnostic methods often prove insufficient for identifying this anomaly.

Observation:

  • A 67-year-old male presented with chest pain, revealing mild stenosis in the right coronary artery (RCA) and left circumflex (LCX) via CT angiography.
  • Coronary angiography indicated severe stenosis in the LCX and RCA, with a unique multi-channel appearance.
  • Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) were performed on the RCA.

Findings:

  • IVUS and OCT definitively confirmed the diagnosis of woven coronary artery.
  • The patient remained asymptomatic for 5 years post-diagnosis without intervention.

Implications:

  • Woven coronary artery can be differentiated from spontaneous coronary artery dissection and thrombosis-related revascularization.
  • IVUS and OCT are crucial for accurate diagnosis, preventing unnecessary invasive procedures.

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Coronary Artery Disease II: Pathophysiology

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...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Acute Coronary Syndrome I: Introduction01:30

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
