This multicenter, prospective, randomized controlled study was designed to evaluate the noninferiority of guided angioplasty by optical frequency domain (OFDI) compared to IVUS. 800 elective patients randomized 1: 1 were included.
The diameter of the stent in the IVUS group was higher than in the OFDI group (p = 0.03). Post implant angiography showed a similar minimal lumen diameter between the two methods. Angiographic follow-up at 8 months and clinical at 12 months is ongoing.
Conclusion
Initial results showed minimal luminal-like area between both groups with a slightly smaller diameter of stent in the OFDI guided group.
