Balloon Alignment T-Stenting for Bifurcation Coronary Artery Disease Using the Sirolimus-Eluting Stent

Coronary arteries.Final result.Widely patent LAD and diagonal arteries are achieved utilizing a balloon alignment T-stenting procedure.Prior to intervention, severe bifurcation disease is present in the LAD and major diagonal branch.Wire access of both the main vessel and the side branch.A balloon in the main branch is used to align the stent in the side branch. The two will then be simultaneously inflated in step 3, allowing for precise ostial alignment of the stent in the side branch without "overhand" or protrusion in the main vessel.Simultaneous inflation of the balloon in the main branch and the stent in the side branch allows for ostial alignment of the side branch stent. The stent delivery system in the side branch should abut the mid-portion of the balloon in the main branch to eMain branch stent placement (T-stenting across the side branch) incarcerates the side branch. The side branch is generally well protected by the ostial location of its stent deployment for re-accessing the side branch. It is imperative to fully postdilateIt is imperative in the final step to re-cross into the side branch and redilate its ostium, allowing for full expansion of the side branch ostium. This is a critical step in reducing vulnerability to side branch restenosis.

Case Presentation. A 65-year-old gentleman, who works as a professional football referee, presented with progressive symptoms of angina. His job officiating games necessitated significant physical activity and endurance. He presented 10 days prior to the opening game of the season and was referred for subsequent noninvasive testing, which demonstrated a large area of ischemia in the anterior and anterolateral distribution.
Cardiac catheterization demonstrated high-grade bifurcation disease involving the left anterior descending artery (LAD), as well as the major diagonal branch. We performed bifurcation percutaneous coronary intervention (P.C.I.) with drug-eluting stents (DES) utilizing a novel “balloon alignment T-stenting” technique (described below). The patient returned to work shortly thereafter and completed the current season.
Upon completion of the current football season in which he continued to be actively involved as a referee, we performed a 9-month anniversary angiogram which showed wide patency of both the LAD and the diagonal branch. No evidence of in-stent restenosis in either vessel was present.
Our center has now performed 30 consecutive bifurcation PCIs exclusively utilizing drug-eluting stents implanted through this technique. We are in the process of collecting follow-up data including quantitative coronary angiography. The balloon alignment T-stenting technique is described below in detail. The full follow-up analysis of our study is the subject of a future manuscript which is currently in preparation.
