BACKGROUND

This study evaluated the views of the cardiology community on the clinical use of coronary intravascular imaging (IVI).Methods and Results:A web-based survey was distributed to 31,893 individuals, with 1,105 responses received (3.5% response rate); 1,010 of 1,097 respondents (92.1%) self-reported as interventional cardiologists, 754 (68.7%) with >10 years experience. Overall, 96.1% had personal experience with IVI (95.5% with intravascular ultrasound [IVUS], 69.8% with optical coherence tomography [OCT], and 7.9% with near-infrared spectroscopy); 34.7% of respondents were from Europe and 52.0% were from Asia (45.4% from Japan). The most commonly reported indications for IVI were optimization of stenting (88.5%), procedural/strategy guidance (79.6%), and guidance of left main interventions (77.0%). Most respondents reported perceived equipoise regarding choice between IVUS and OCT for guidance of coronary intervention. High cost (65.9%) and prolongation of the procedure (35.0%) were the most commonly reported factors limiting use. IVI was used more frequently (>15% of cases guided by IVI) in Japan than Europe (96.6% vs. 10.4%, respectively; P<0.001) and by operators with longer interventional experience.

CONCLUSIONS

In a sample of predominantly experienced interventional cardiologists, there was a high rate of personal experience with IVI in clinical practice. The most commonly identified indications for IVI were optimization of stenting, procedural/strategy guidance, and guidance of left main interventions. Variability in practice patterns is substantial according to geographic region and interventional experience.
