Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

161
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Acute Coronary Syndrome III: Diagnostic Studies

114
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

247
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...

Acute Coronary Syndrome I: Introduction

438
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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Summary

Spontaneous coronary artery dissection (SCAD) is a rare cause of heart attack in young athletes. Early diagnosis and recognition of complications like thrombus are crucial for effective treatment.

Area of Science:

  • Cardiology
  • Cardiovascular Imaging
  • Sports Cardiology

Background:

  • Spontaneous coronary artery dissection (SCAD) is an uncommon cause of myocardial infarction, particularly in young, healthy individuals.
  • Athletes may present with anginal symptoms mimicking typical exertional angina, complicating diagnosis.

Observation:

  • A 19-year-old collegiate athlete experienced anginal symptoms post-exercise, with elevated troponin and CK-MB levels.
  • ECG revealed diffuse biphasic T-waves; coronary CT angiography showed left anterior descending artery dissection and left ventricular apical thrombus.

Findings:

  • Coronary catheterization confirmed left anterior descending artery dissection.
  • The case highlights SCAD as a differential diagnosis in young athletes with non-ST-elevation myocardial infarction (NSTEMI).

Implications:

  • Prompt diagnosis of SCAD is essential, even in the absence of traditional risk factors.
  • Awareness of potential complications, such as intracardiac thrombi, is critical for guiding therapeutic strategies and improving patient outcomes.
