Role of Final Kissing Balloon Inflation in Left Main Distal Bifurcation Single Stenting: Insights from Angiographic Microvascular Resistance.

ABSTRACT: Background and Objectives: The roles of final kissing balloon inflation (FKBI) in single stenting remain controversial, with no prior studies evaluating its impact on angiographic restenosis from the perspective of coronary microcirculation. This study aimed to investigate whether FKBI reduced angiographic restenosis in patients treated with single stenting in the left main (LM)-left anterior descending (LAD) after propensity score matching (PSM) to balance baseline characteristics, including the pre-procedural angiography-derived index of microcirculatory resistance (AMR). Additionally, it aimed to demonstrate the temporal changes in AMR (pre-procedure, post-procedure, and follow-up) and their impact on angiographic restenosis. Materials and Methods: AMR was calculated based
