Percutaneous intervention with balloon dilatation and drug-eluting stent restored TIMI 3 flow in the obstructed accessory LAD in a 49-year-old man with a rare Type X dual LAD coronary anomaly.
Case Report (n=1)
No
This case highlights the importance of recognizing uncommon coronary artery anomalies, such as a Type X dual LAD, which can significantly influence diagnostic and therapeutic strategies during interventional procedures.
Absolute Event Rate: 100% vs 0%
A 49-year-old man presented with acute onset chest pain and new-onset right bundle branch block. Echocardiography revealed mild apical hypokinesia with an ejection fraction of 45%. Coronary angiography showed all three major coronary arteries originating from the right coronary sinus with normal flow. Further evaluation identified an obstructed accessory left anterior descending (LAD) artery arising from the left sinus. Successful wire crossing, balloon dilatation, and deployment of a drug-eluting stent restored TIMI 3 flow. Subsequent computed tomography angiography confirmed a rare Type X dual LAD anatomy. This case highlights the importance of recognizing uncommon coronary artery anomalies since they may significantly influence diagnostic and therapeutic strategies.
J et al. (Thu,) conducted a case report in A 49-year-old man with acute chest pain, new-onset right bundle branch block, and mild apical hypokinesia with reduced ejection fraction (45%) (n=1). Percutaneous coronary intervention with balloon dilatation and drug-eluting stent deployment (size 3, 28 mm) in accessory left anterior descending artery was evaluated on Restoration of TIMI 3 flow in obstructed accessory left anterior descending artery. Percutaneous intervention with balloon dilatation and drug-eluting stent restored TIMI 3 flow in the obstructed accessory LAD in a 49-year-old man with a rare Type X dual LAD coronary anomaly.
