Key result

A technique using two over-the-wire dilatation systems achieved successful major vessel dilatation in 100% (8/8) of patients with bifurcational lesions, with no associated complications.

Why the study?

Does a technique using two over-the-wire dilatation systems improve procedural success and prevent side branch occlusion in patients undergoing angioplasty for bifurcational lesions?

Population

8 patients undergoing coronary angioplasty for a bifurcational lesion in the left anterior descending or…

Implication

Supports feasibility in small series; hypothesis-generating, should not change practice without larger studies.

Key Points

To evaluate a dual over-the-wire balloon dilatation technique designed to prevent iatrogenic side branch occlusion during angioplasty of coronary bifurcation lesions.
Assessed an interventional technique using two simultaneous over-the-wire dilatation systems positioned in the stenosed primary vessel and adjacent side branch.
Treated N=8 patients undergoing coronary angioplasty for lesions in the left anterior descending or circumflex arteries located near a major branch.
Successful dilatation of the major vessel was achieved in 100% (8/8) of patients, and side branch dilatation was successful in all 3 patients with ostial involvement.
One patient experienced partial side branch closure during main vessel dilation, which was promptly resolved using the prepositioned guide wire without procedural complications.

Does a technique using two over-the-wire dilatation systems improve procedural success and prevent side branch occlusion in patients undergoing angioplasty for bifurcational lesions?

Population

8 patients undergoing coronary angioplasty for a bifurcational lesion in the left anterior descending or circumflex artery located near a large side branch.

Intervention

A technique using two over-the-wire dilatation systems positioned within the stenosed coronary artery and the side branch in jeopardy.

Outcome

Procedural success (successful dilatation of the major vessel lesion and side branch) and procedural complications.safety

The use of two over-the-wire dilatation systems appears to be a safe and efficacious method for performing coronary angioplasty in bifurcational lesions to prevent iatrogenic side branch occlusion.
