Key result

The modified T-stenting technique with crushing for true bifurcation lesions was feasible, with 2 in-hospital myocardial infarctions and 1 re-PTCA occurring among 20 treated patients at 30 days.

Why the study?

Is the modified T-stenting technique with crushing feasible and safe for treating true bifurcation lesions?

Key Points

To evaluate the feasibility, immediate angiographic success, and 30-day clinical outcomes of a modified crush T-stenting technique using drug-eluting stents for true coronary bifurcation lesions.
Interventional study in 20 consecutive patients undergoing percutaneous coronary intervention for true bifurcation lesions using sirolimus-eluting Cypher stents.
The side-branch stent was deployed with 4–5 mm protruding into the main branch and subsequently crushed against the vessel wall during main-branch stent expansion, followed by optional kissing balloon post-dilatation.
Stent delivery and deployment were successfully achieved in 100% of lesions (20/20), with final kissing balloon inflation performed in 7 patients (35%).
In-hospital complications occurred in 3 patients (15%), comprising 2 myocardial infarctions and 1 repeat angioplasty due to distal vessel dissection, with no further major adverse cardiac events observed through 30-day follow-up.

Is the modified T-stenting technique with crushing feasible and safe for treating true bifurcation lesions?

Population

20 consecutive patients with true bifurcation lesions

Intervention

Modified T-stenting technique with crushing using a drug-eluting stent (Cypher stent)

Outcome

Procedural success and major adverse cardiac events (MACE) in-hospital and at 1-month clinical follow-upsafety

The modified T-stenting technique with crushing using drug-eluting stents is feasible for bifurcation lesions with an acceptable rate of procedural complications at 30 days.

Limitations

Lack of angiographic follow-up to prove complete coverage of the ostium of the side branch
Lack of angiographic follow-up to prove the advantage of complete coverage of the ostium

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Small case series suggests feasibility of modified T-stenting with crushing; leaves open need for randomized safety and outcome data.
