Abstract 15993: Does Optical Coherence Tomography Guided Percutaneous Coronary Intervention Reduce Resource Utilization?
Background: Optical coherence tomography (OCT) was recently introduced to optimize percutaneous coronary intervention (PCI). Pre-PCI OCT evaluation may help develop optimal strategy and potentially reduce resource utilization.
Aims: To test the hypothesis that OCT-guided PCI, compared to angio-guided PCI, would reduce resource utilization.
Methods and Results: A total of 429 PCI cases were selected from the cath lab database: 143 OCT-guided and 286 angio-guided cases. They were matched on propensity score derived from a logistic model determined by clinical and angiographic factors. Resources studied included number of stents, number of balloons, procedure time, contrast volume, and fluoroscopy time. OCT-guided cases had a significant shorter fluoroscopy time compared to angio-guided cases (16.5 vs. 20.5 min, p=0.006), but no significant difference was observed in balloon usage, stent usage, procedure time, or contrast volume.
Conclusions: This study failed to demonstrate that OCT-guided PCI reduces resource utilization compared to angio-guided PCI. Investigation of whether OCT-guided PCI improves clinical outcome requires large scale prospective studies.
