5. Study Description
Brief Summary
This study will examine use of two-stent versus one-stent techniques for patients with large calibre bifurcation lesions including significant side branch disease.
Detailed Description
Treatment of bifurcation coronary lesions remains a difficult area, in which best practice is yet to be established. Prior to the era of drug-eluting stents, the limited data which existed suggested that a strategy of stenting the main vessel, with balloon angioplasty alone of the side-branch if required was superior to stenting both vessels.
Randomised trials of "all-comer" bifurcation lesions have now established that there is no advantage to systematic dual drug-eluting stent strategies. However, these trials included patients with no disease in the side branch, and small side branch vessels.
Expert consensus suggests that "large" bifurcations with significant ostial side branch disease still merit a systematic total lesion coverage stent technique. This trial therefore is designed to assess the hypothesis that large true bifurcations with significant side branch ostial disease are more successfully treated with a systematic culotte technique than with the provisional T approach.
