This study aimed to assess current procedural strategies and perceptions for percutaneous coronary intervention (PCI) involving bifurcations. The survey results showed that the DK crush technique was the most frequently used 2-stent strategy. For left main lesions, approximately 25% of cases underwent bailout stenting after provisional strategy. For non-left main lesions, the use of intravascular imaging and coronary physiology was lower than for left main lesions.
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.
