Abstract:: There is no data on the impact of coronary computed tomography angiography (coronary CTA), as an addition to angiography, on the outcomes of percutaneous coronary interventions (PCI) in bifurcation lesions. Patients with stable coronary artery disease scheduled for elective bifurcation PCI were randomized 1:1 to planning the procedure based on coronary CTA and angiography (CTA group) or angiography alone (CA group). The primary efficacy endpoint was the immediate angiographic result. Secondary efficacy endpoints were: a) procedural characteristics and b) postprocedural fractional flow reserve (FFR) in the side branch (SB) in a subgroup of patients. Safety outcomes were: a) periprocedural myocardial infarction, b) contrast use and c) radiation dose. PCI of 45 lesions in the CTA group and 47 lesions in the CA group was performed. Postprocedural lumen diameters in the main branch (MB) and SB, frequency of SB compromise or occlusion and mean SB FFR values were not different between study groups. Two or more stents were implanted less frequently in the CTA group than in the CA group (18% vs. 43%, p = 0.01). This difference was driven by less frequent MB 2-stent overlap in the CTA group (7 vs. 21%, p = 0.046) and numerically less SB stenting (11% vs. 21%, p = 0.07). Proximal optimization technique was used more frequently in the CTA group (44% vs. 21%, p = 0.018). CTA-assisted bifurcation PCI leads to similar immediate results compared with angiography alone, however is associated with higher use of single-stent procedures with proximal optimization, less frequent 2-stent overlap and less SB stenting.
