OCT-Guided PCI According to Lesion Length and Vessel Diameter

Puntos clave

This analysis aims to evaluate the effectiveness of OCT-guided PCI concerning lesion lengths and vessel diameters.
Post hoc analysis of the OCCUPI trial data.
Evaluation of clinical outcomes based on lesion lengths and reference vessel diameter (RVD).
Comparison of outcomes in lesions ≥32 mm with RVD <2.8 mm.
OCT-guided PCI showed consistent clinical outcomes across various lesion lengths and RVD.
The most significant benefits were seen in lesions measuring ≥32 mm with a reference vessel diameter of less than 2.8 mm.
Overall, OCT guidance indicates a positive impact on treatment efficacy.

Resumen

This post hoc analysis of the OCCUPI trial showed that clinical outcomes consistently favored OCT-guided PCI across varying lesion lengths and RVD, with the most pronounced benefit evident in lesions ≥32 mm with RVD <2.8 mm.
