Abstract
T and small protrusion (TAP) is a stenting technique that is utilized for the management of coronary bifurcation lesions when using a two-stent strategy. This technique is also useful whenever stenting of a main vessel (MV) jeopardizes a side branch (SB) or when a sub-optimal result is encountered in a daughter vessel after starting with one-stent approach. The conversion from one-stent strategy to TAP could be achieved smoothly and often leads to good results. Technically, optimal positioning of the SB stent to achieve the required protrusion into the lumen of the MV remains a challenge. Toward that goal we propose an added step that involves inflating a balloon in the MV to serve as an anvil with simultaneous pullback of the SB stent, to be followed by stent deployment. We refer to this approach as the snuggle T and protrusion (S-TAP) technique owing to close contact between the SB stent and the MV balloon during simultaneous inflation. In this manuscript, we detail this interventional technique and provide a demonstrative case study.
