Insights

A patient with ST elevation myocardial infarction had a rare dual-origin left anterior descending artery. This congenital anomaly increases the risk of future cardiac events, necessitating careful monitoring.

Area of Science:

  • Cardiology
  • Anatomical Variations
  • Interventional Cardiology

Background:

  • Congenital coronary artery anomalies are rare but can lead to significant cardiovascular events.
  • Anomalous origin of the coronary arteries can predispose individuals to myocardial ischemia and infarction.

Observation:

  • A case of acute ST elevation myocardial infarction (STEMI) due to right coronary artery occlusion is presented.
  • Coronary angiography and multislice CT revealed a single right coronary artery with two anomalous left coronary system branches (Yamanaka R-IIIC).
  • These branches formed a dual origin left anterior descending artery, with an unusual course between the pulmonary trunk and aorta.

Findings:

  • Successful treatment of STEMI was achieved with thrombectomy and percutaneous coronary intervention (PCI).
  • The identified coronary anomaly, a Yamanaka R-IIIC subtype, presents a unique anatomical configuration.
  • This specific anomaly poses an increased risk for future myocardial ischemia, infarction, and sudden cardiac death.

Implications:

  • Patients with this coronary anomaly are at high risk for exertional myocardial ischemia.
  • Exercise myocardial perfusion imaging may be beneficial for identifying high-risk individuals within this cohort.
  • Awareness of such rare anomalies is crucial for accurate diagnosis and risk stratification in cardiology.

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 II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

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...

Coronary Circulation01:21

Coronary Circulation

The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
