ABSTRACT

Coronary bifurcation lesions, present in approximately 15-20% of percutaneous coronary interventions (PCI), pose a challenging area in interventional cardiology. In cases requiring side branch stenting, the T-stenting and TAP (T and small protrusion) techniques are critical for reducing procedural complications and optimizing treatment efficiency. T-stenting is typically applied when the bifurcation angle approaches 90 degrees, while TAP is preferred for angles over 70 degrees. Initially developed as bailout strategies for compromised side branches, these techniques have been widely adopted as planned dual stent strategies. This section explores the T and TAP stenting techniques in detail, outlining step-by-step procedures, key advantages, potential challenges, and recommended management strategies.
