This is an observational, prospective, multicenter study using optical coherence tomography (OCT) and measurement of fractional flow reserve (FFR) before and after angioplasty. Inpatient following up was set at one month, six months, and one year. Before performing the OCT, the planned strategy was recorded and surgeons were free to change the strategy. The strategy of the procedure was modified based on information obtained from the OCT pre angioplasty in 57% of cases. After angioplasty, the OCT led to an optimization itself in 27% of cases.
Conclusion
The information provided by the OCT influenced the decision of operators in a total of 65%. Changing strategy based on OCT seems to be associated with reduced periprocedural infarct rate. These data should be corroborated in randomized prospective studies.
