Insights

A rare coronary artery anomaly caused chest pain in a woman. Multislice-computed tomography (MSCT) helped diagnose the abnormal right coronary artery (RCA), and stenting relieved her symptoms.

Area of Science:

  • Cardiology
  • Radiology
  • Medical Imaging

Background:

  • Coronary artery anomalies are uncommon but can lead to significant clinical issues.
  • Accurate diagnosis of these anomalies is crucial for effective patient management.
  • Symptoms like crescendo angina can indicate underlying coronary artery pathology.

Purpose of the Study:

  • To report a case of anomalous right coronary artery (RCA) originating from the left sinus of Valsalva.
  • To highlight the utility of Multislice-computed tomography (MSCT) in visualizing coronary artery anomalies.
  • To demonstrate the successful treatment of symptomatic coronary artery anomaly with percutaneous coronary intervention.

Main Methods:

  • A 42-year-old woman with crescendo angina underwent diagnostic imaging.
  • Thallium-scintigraphy and coronary angiography were performed to assess cardiac ischemia and coronary anatomy.
  • Multislice-computed tomography (MSCT) was utilized for detailed evaluation of the anomalous coronary artery course.

Main Results:

  • Coronary angiography revealed a right coronary artery (RCA) arising from the left sinus of Valsalva with severe proximal systolic compression.
  • MSCT effectively depicted the anomalous RCA and its inter-arterial course.
  • Transradial percutaneous coronary intervention with stent implantation successfully relieved the patient's symptoms.

Conclusions:

  • Anomalous origin of the coronary arteries, though rare, requires accurate diagnosis.
  • MSCT is a valuable tool for detailed characterization of coronary artery anomalies.
  • Percutaneous coronary intervention with stenting can be an effective treatment for symptomatic coronary artery anomalies.

Imaging Studies for Cardiovascular System V: CT

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...

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
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...

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...
