Methods: Bench and in-vivo evaluations were performed. For the bench visualization bifurcated silicone mock vessel was used. The POKI technique 💯 was simulated using a 3.5 mm POT balloon. For the in-vivo evaluation patients with angiographic bifurcation lesions in a native 💯 coronary artery with diameter ≥ 2.5 mm and ≤ 4.5 mm, SB diameter ≥ 2.0 mm, and percentage diameter stenosis 💯 (%DS) more than 50% in the main vessel (MV) were included. Provisional stenting was the default strategy.
Background: Percutaneous coronary interventions 💯 (PCI) of bifurcation lesions poses a technical challenge with a high complication rate. Kissing balloon inflation (KBI) and proximal optimization 💯 technique (POT) are used to correct bifurcation carina after stenting. However, both may still lead to uncomplete strut apposition to 💯 the side branch (SB) lateral wall. Proposed herein, is a new stent-optimization technique following bifurcation stenting consisting of a combination 💯 of POT and KBI called proximal optimization with kissing balloon inflation (POKI).
