Figure 1: “Provisional” T-stenting with small protrusion technique step by step in a bench model. (a) The stent for the side branch is placed with a minimal protrusion in the main vessel and an uninflated balloon is prepared for final kissing in the main vessel. (b) The side branch stent is deployed with the main vessel balloon uninflated. (c) The balloon of the side branch stent is pulled back to achieve perfect alignment with the main vessel balloon. (d) Kissing balloon inflation is performed with the side branch stent's balloon and the main vessel balloon. (e) Final result with T-stenting with small protrusion stenting.
