OBJECTIVES: The study aim was to assess current procedural strategies and perceptions for percutaneous coronary intervention (PCI) involving bifurcations. METHODS: We distributed an online survey via email (8050 invitations) and social media. RESULTS: Among 440 responders, median annual PCI volumes were 15 cases (interquartile range [IQR], 10-29 cases) for left main (LM) and 50 cases (IQR, 27-73 cases) for non-LM (nLM) bifurcation lesions. Radial access use was reported in 51% of LM and 82% of nLM cases. An upfront 2-stent strategy, most commonly double-kissing (DK) crush, was reported in 49% of LM and 29% of nLM lesions. Bailout stenting during provisional stenting was reported in 26% of LM-PCIs, usually using the T and protrusion technique. In provisional stenting cases, most operators (<35%) did not report predilating the side branch, but routinely postdilated after successful provisional stenting (>85%), most often using both kissing-balloon inflation and the proximal optimization technique. Intravascular imaging was used in 80% of LM and 46% of nLM cases. CONCLUSIONS: Among the survey responders, the DK crush technique was the most frequently used 2-stent strategy for bifurcation PCIs. For LM lesions, bailout stenting was performed after provisional strategy in approximately 25% of cases. For nLM lesions, use of intravascular imaging and coronary physiology was lower than for LM lesions.
