"Brass Knuckle"-Like Right Coronary Artery.

Area of Science:

• Cardiology
• Medical Imaging
• Anatomical Variations

Background:

• Patent foramen ovale and right atrial masses are potential cardiac findings requiring investigation.
• Coronary artery anomalies are relatively common and often found incidentally during cardiac evaluations.
• Clinical presentation is crucial for guiding the diagnostic and therapeutic approach to coronary anomalies.

Purpose of the Study:

• To report an incidental finding of a significant coronary artery anomaly.
• To illustrate the diagnostic process for unexpected cardiac structures.
• To emphasize the importance of clinical correlation in managing coronary anomalies.

Main Methods:

• Patient presented for invasive evaluation of patent foramen ovale and suspected right atrial formation.
• Transthoracic echocardiography and transesophageal echocardiography were performed for diagnostic imaging.
• Imaging modalities were used to assess cardiac structures and rule out initial suspected pathologies.

Main Results:

• Initial suspected patent foramen ovale and right atrial mass were excluded by echocardiography.
• Echocardiography revealed a large, "brass knuckle"-like ectasia of the right coronary artery.
• The ectatic right coronary artery was observed to meander along the lateral wall of the right atrium.

Conclusions:

• Incidental discovery of coronary artery anomalies, such as right coronary artery ectasia, is not uncommon.
• Echocardiography can effectively visualize significant coronary artery abnormalities.
• Management strategies for coronary anomalies should be tailored to the individual patient's clinical presentation and symptoms.
