[Percutaneous coronary intervention on a single coronary ostium]

Area of Science:

• Cardiovascular Medicine
• Congenital Heart Disease
• Interventional Cardiology

Background:

• Anomalous origin of the left main coronary artery from the right sinus of Valsalva (ALMC-RSV) is a rare congenital cardiac anomaly.
• It typically constitutes only 0.019% of angiographic series and is often asymptomatic.
• Patients may present with normal coronary arteries or be prone to premature atherosclerotic disease.

Observation:

• This report details an unusual case of a patient presenting with ST-segment elevation myocardial infarction (STEMI).
• The patient had an anomalous origin of the left main coronary artery from the right sinus of Valsalva.
• The coronary anatomy was unusual, originating from a single ostium.

Findings:

• The patient with ALMC-RSV experienced an ST-segment elevation myocardial infarction.
• Management involved percutaneous coronary intervention (PCI).
• The PCI was successfully performed through a single coronary ostium, despite the anomalous coronary origin.

Implications:

• This case underscores the importance of considering rare coronary anomalies in the differential diagnosis of myocardial infarction, even in younger patients.
• Percutaneous coronary intervention can be a viable treatment option for acute coronary syndromes in patients with ALMC-RSV.
• Further research into the long-term outcomes and optimal management strategies for ALMC-RSV is warranted.
