title: A new anomaly of the left anterior descending artery: Type X dual LAD.
abstract: Dual left anterior descending (LAD) coronary artery anomaly is traditionally classified as four types anomaly by classical coronary angiogram. Nowadays, coronary computed tomographic angiography (CCTA) allows clinicians to understand other variants of dual LAD anomaly. Up to date, 9 types of dual LAD variants detected from not only classical coronary angiogram but also CCTA imaging have been reported. In the present case, we aimed to show a novel dual LAD anomaly, which is demonstrated by CCTA during preoperative evaluation and it has not been previously reported.
