Key result
Percutaneous coronary intervention with stenting successfully treated a 50-70% stenosis in a major diagonal branch of a rare type 4 dual left anterior descending artery, maintaining patency at 10 years.
Why the study?
Dual left anterior descending artery is a rare congenital coronary anomaly with multiple types, and type 4 is among the rarest, requiring recognition for accurate diagnosis and intervention planning.

Highlights the clinical importance of recognizing rare congenital coronary anomalies, such as the type 4 dual LAD artery, for accurate diagnosis and planning of revascularization procedures.
Dual left anterior descending artery (LAD) is a rare congenital coronary artery anomaly with a prevalence of approximately 1% in the general population. To date, 10 types of dual LAD artery anomalies have been reported. Among these, type 4 is one of the rarest. Knowledge and recognition of the dual LAD artery are important for correct diagnosis and planning of coronary bypass surgery and percutaneous coronary intervention. We report a case of a 59-year-old male with type 4 dual LAD artery who presented with dyspepsia and sweating for several months and had approximately 50%-70% stenosis in a major diagonal branch off the short LAD artery.

Jang et al. (2023) conducted a case report in Type 4 dual left anterior descending artery with stenosis (n=1). Percutaneous coronary intervention (balloon angioplasty and stenting) was evaluated on Symptom resolution and stent patency. Percutaneous coronary intervention with stenting successfully treated a 50-70% stenosis in a major diagonal branch of a rare type 4 dual left anterior descending artery, maintaining patency at 10 years.
