Multivessel coronary-ventricular fistulae and ischaemia on cardiac MRI

Insights

Multivessel coronary ventricular fistulae, a rare anomaly, can cause a coronary steal phenomenon. Cardiac MRI confirmed subendocardial ischemia in a patient, validating this rare condition.

Area of Science:

  • Cardiology
  • Cardiac Imaging
  • Congenital Heart Disease

Background:

  • Multivessel coronary ventricular fistulae are rare coronary anomalies.
  • Their clinical and hemodynamic significance remains controversial.
  • Potential origins include arterioluminal or arteriosinusoidal connections.

Observation:

  • A 69-year-old female presented with exertional dyspnea and atypical chest pain.
  • She had multivessel coronary to left ventricular fistulae.
  • Cardiac MRI with adenosine stress was performed for evaluation.

Findings:

  • The cardiac MRI revealed subendocardial ischemia in multiple coronary territories.
  • This finding confirmed a coronary steal phenomenon.
  • The results highlight the hemodynamic impact of these fistulae.

Implications:

  • This case underscores the importance of considering coronary ventricular fistulae in patients with unexplained ischemic symptoms.
  • Cardiac MRI with stress is a valuable tool for diagnosing coronary steal.
  • Further research is needed to fully understand the clinical significance and management of these anomalies.

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Mitral Stenosis II: Clinical features and Diagnostic Tests

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...
