Insights

We identified a rare combination of single coronary artery and double-outlet right ventricle using echocardiography. This finding impacts surgical planning for arterial switch repairs in affected patients.

Area of Science:

  • Cardiovascular Imaging
  • Pediatric Cardiology
  • Congenital Heart Disease

Background:

  • Double-outlet right ventricle (DORV) is a complex congenital heart defect.
  • Coronary artery anomalies can coexist with DORV, influencing surgical outcomes.
  • Accurate pre-operative diagnosis is crucial for effective management.

Purpose of the Study:

  • To report the echocardiographic diagnosis of a combined single coronary artery and DORV.
  • To highlight the initial recognition of this coronary artery variation using subcostal coronal imaging.
  • To discuss the implications for arterial switch repair in patients with this anomaly.

Main Methods:

  • Echocardiographic imaging was performed to diagnose the cardiac anomaly.
  • Subcostal coronal views were utilized for initial identification of the coronary artery variation.
  • Review of relevant literature and surgical considerations.

Main Results:

  • The echocardiographic diagnosis of single coronary artery combined with DORV was successfully made.
  • This specific coronary artery variation was initially identified in the subcostal coronal axis.
  • The combination occurs in approximately 11% of DORV patients.

Conclusions:

  • Echocardiography is effective in diagnosing combined single coronary artery and DORV.
  • Subcostal coronal imaging is valuable for identifying this coronary artery variation.
  • This anatomical combination presents significant challenges for coronary artery transfer during arterial switch repair.

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...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

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...

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...
Aortic Regurgitation II: Clinical Features and Diagnostic Tests01:22

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

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...
