Abstract

Background: It is estimated that fifteen to twenty percent of all percutaneous coronary interventions are bifurcation PCIs. Bifurcation intervention is regarded as one of the most challenging procedures in the field of interventional cardiology, both in terms of the success rate of the procedure itself as well as the incidence of long-term cardiac events. Aim and objectives: to assess the impact of side branch ostium management with either KBI or RE-POT in non-left main bifurcations provisionally stented. patients and methods: Retrospective and prospective study of 100 patients, 73 male and 27 female with non-left main bifurcation lesions treated with single DES strategy, in Damnhour Medical National Institute and the Islamic Cardiac Center from march 2021 to march 2023. After provisional stenting and proximal optimization, cases were separated into 3 groups according on the method utilized for side branch post dilatation. In one group KBI was used, in another group re-POT was used and in the third group no further management after proximal optimization. Results: TIMI flow in the main branch & side branch post intervention, procedural complications, and recurring chest discomfort in a minimum of 3 m follow up presented no statistically significant difference amongst the trial groups. Conclusion: Side-branch ostium dilatation after provisional stenting in non-LM bifurcations provisionally stented is not a routine step, only performed if there is no satisfactory flow in a sizable side branch. There is no significant difference between kissing balloon inflation and re-POT as complementary steps for side branch ostium dilatation after provisional stenting of the main vessel and proximal optimization.
