Study design: Case Report
Abstract: Background: This case highlights a type 4 dual left anterior descending coronary artery anomaly, identified incidentally during coronary angiography. Case summary: A 51-year-old male patient presented with acute myocardial infarction, which was successfully treated with thrombolysis and percutaneous coronary intervention. Angiography revealed an anomalous origin of the left anterior descending artery (LAD) from the right coronary artery. Stenting was performed on the right coronary artery and the right posterior descending artery branch. Discussion: Type 4 dual LAD is a rare coronary anomaly with potential clinical risks, including sudden cardiac death due to its course between major arteries. Variations in the structure of coronary arteries can present challenges for interventional cardiologists when conducting percutaneous coronary interventions. Accurate coronary anatomy assessment via angiography and computed tomography coronary angiography is crucial for successful percutaneous coronary intervention and surgical planning. Although uncommon, the dual LAD type 4 anomaly is a significant coronary artery variation that interventional cardiologists must consider due to its impact on prognosis and long-term treatment strategies.
