Single right coronary artery with congenital absence of left coronary system

Area of Science:

• Cardiology
• Medical Imaging
• Congenital Heart Disease

Background:

• Single coronary artery (SCA) is an exceptionally rare congenital coronary anomaly.
• Accurate diagnosis necessitates comprehensive multimodality imaging of coronary anatomy.
• SCA is frequently discovered incidentally during investigations for suspected coronary artery disease.

Observation:

• The case involved a young male patient presenting with non-ST elevation myocardial infarction.
• Initial diagnostic workup included invasive coronary angiography.
• Echocardiography and electrocardiography lack established criteria for SCA diagnosis.

Findings:

• Invasive coronary angiography revealed a single coronary artery (SCA).
• CT coronary angiography confirmed the SCA diagnosis.
• The patient's presentation of myocardial infarction in the context of SCA is noteworthy.

Implications:

• This case underscores the importance of multimodality imaging for diagnosing rare coronary anomalies like SCA.
• Accurate diagnosis of SCA is crucial for appropriate patient management and risk stratification.
• Further research may explore diagnostic challenges and optimal imaging strategies for SCA.
