Percutaneous transluminal coronary angioplasty of the left main coronary artery with a 5Fr catheter system

The protected left main coronary artery (LM) is accessible to percutaneous transluminal coronary angioplasty (PTCA), and the procedure is usually performed with large size catheter systems. This report describes a successful PTCA of a partially protected LM through a 5Fr diagnostic catheter system in a patient with previous coronary artery bypass grafting. Such an approach is time- and cost-efficient when combined with the diagnostic study.
