Treatment of a coronary aneurysm involving bifurcation with the use of a custom-made polytetrafluoroethylene-coveredbifurcation stent system

We report a case with a large aneurysm of the proximal left anterior descending coronary artery involving the bifurcation with a diagonal branch. We used a custom-made bifurcation system with a polytetrafluoroethylene-covered stent for the main branch and a bare metal stent for the side branch with excellent clinical and angiographic result at 5-month follow-up.
