Coronary Stenting in a Patient With Dual Left Anterior Descending Artery

Double left anterior descending coronary artery (LAD) originating from the left main stem and the right coronary artery (type IV dual LAD) is a extremely rare coronary artery anomaly. We report a case of type IV dual LAD in a patient with history of myocardial infarction and worsening effort angina. The proper LAD and both the circumflex (Cx) and the right coronary (RCA) arteries showed multiple severe stenoses. The patient underwent successful percutaneous coronary intervention.
