Resolution of ischemia with β-blocker in a patient with anomalous right coronary artery

Area of Science:

• Cardiology
• Cardiac Surgery
• Clinical Medicine

Background:

• Anomalous origin of the right coronary artery (RCA) is a rare congenital heart defect.
• It is often linked to significant cardiovascular events such as angina, myocardial infarction, and sudden cardiac death.
• Surgical intervention is frequently considered the primary treatment for symptomatic anomalous RCA.

Observation:

• The study presents a case of anomalous RCA.
• The patient experienced symptoms suggestive of myocardial ischemia.
• Serial stress testing was employed for objective assessment.

Findings:

• Long-term beta-blocker therapy was initiated as an alternative to surgery.
• Objective evidence from serial stress testing demonstrated a resolution of ischemia.
• This suggests a non-surgical management approach can be effective.

Implications:

• Beta-blocker therapy may be a viable alternative to surgery for select patients with anomalous RCA.
• Objective stress testing is crucial for monitoring treatment efficacy.
• This finding could influence clinical decision-making for anomalous coronary artery origins.
