Imaging Studies for Cardiovascular System V: CT

460
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

351
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...

Mitral Stenosis II: Clinical features and Diagnostic Tests

371
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Acute Coronary Syndrome I: Introduction

1.3K
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...

Area of Science:

  • Cardiology
  • Medical Imaging
  • Interventional Cardiology

Background:

  • Acute chest pain presentation in a 62-year-old woman.
  • Electrocardiogram (ECG) changes and reduced left ventricular ejection fraction (30%) on echocardiogram indicated significant cardiac compromise.

Observation:

  • Emergent cardiac catheterization revealed severe flow disturbance in the left coronary artery.
  • Initial interventions including an intra-aortic balloon pump and drug-eluting stent implantation did not fully resolve the flow disturbance.

Findings:

  • Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) provided critical insights into the underlying mechanism of persistent coronary artery flow disturbance.
  • These advanced intravascular imaging techniques were instrumental in guiding further treatment optimization.

Implications:

  • OCT and IVUS are valuable tools for complex coronary interventions when initial treatments fail.
  • Optimized treatment strategies based on detailed intravascular imaging can improve outcomes in critical cardiac patients.
