Side Branch Pre-dilation During Provisional Stenting of Coronary Bifurcation Lesions: A Randomized Controlled Trial
Author: Hamidreza Sanati, M.D. Interventional Cardiologist Associate Professor, Rajaei Cardiovascular Medical and Research Center Tehran, IRAN
BACKGROUND
- Elective two-stent strategy is not superior to the provisional stenting.
- Jailed wire technique and pre-dilatation of the SB before MV stenting have been proposed to protect SB during provisional stenting
- Not a precise conclusion from available, albeit rather insufficient data
CONCLUSION
- The study was not sufficiently powered because of the small number of the participants.
- Not statistically significant but from the clinical point of view, the results seem to be important and in accord with other studies.
- Side branch pre-dilation increases the possibility of dissection at the SB ostium and consequently the chance of crossing-over to two-stent strategy. On the other hand, pre-dilation does not facilitate SB access after MV stenting.
- It should be avoided as a routine strategy.
