“…Several studies compared findings with angiographic evaluation alone versus under the guidance of IVUS, and showed lower major adverse cardiac events (MACE) and cardiac death rates at follow up were seen in the IVUS group 7,8, 9 . At the beginning of the procedure, risk factors for SB occlusion after provisional stenting technique should be recognized such as SB stenosis and acute angel of SB [10][11][12][13][14][15] . In this study, we are trying to understand the usefulness of IVUS to help in the prediction of SB collapse after provisional stenting.…”

Background: Coronary bifurcation lesion is important subject in percutaneous coronary intervention (PCI). While much progress has been made in PCI facilities, bifurcation stenting is still has a lot of problems. Objective: The aim of this study was the usefulness of intravascular ultrasound (IVUS) to help in the prediction of occlusion of side branch (SB) after stenting the main vessel (MV) in bifurcation lesions. Patients and methods: The period of this study was from May 2019 to December 2020, and included 80 patients who were submitted for elective coronary angiography to the cardiology department at Maadi Military Hospital, and showed bifurcation lesions treated with provisional stenting using IVUS measurements. Results: This study included two groups according to the occlusion of SB after main vessel stenting .The 1st group had the patients with occlusion of SB (n= 18) and the 2nd group had the patients without occlusion of SB (n= 62). The thinner plaque of main vessel (MV) at junction position with SB, MV plaque area and diameter ratio of SB were the factors which could predict acute occlusion of SB after provisional stenting. Conclusion:In coronary bifurcation lesions, we can use intravascular ultrasound (IVUS) to help in the prediction of occlusion of SB after provisional stenting, and these predictors can help the operators to prepare the best strategy for treating bifurcation lesions.

ObjectivesTo define the impact of side branch (SB) lesion length on clinical outcomes after percutaneous coronary intervention (PCI) on bifurcation lesions.BackgroundThe role of the SB lesion length remains questionable in PCI planning and its implication on clinical outcome is controversial.MethodsData from the retrospective multicenter EBC‐P2BiTO registry were analyzed. The primary endpoint was the occurrence of major adverse cardiac events (MACE), defined as the composite of cardiac death, myocardial infarction excluding periprocedural, or stent thrombosis at 13 months median follow‐up (IQR 11–28). By using propensity scores for inverse probability of treatment weighting (IPTW), the comparison of treatment groups was adjusted to correct for potential confounding.ResultsAmong 1,252 patients, SB was normal in 489 (39%), diseased in 763 (61%) cases. MACE occurred in 68 patients (5.4%). The optimal discriminant SB lesion length for MACE was ≥10 mm, with an area under the curve of 0.71 (p < .01).The incidence of MACE was higher among patients with SB lesions ≥10 mm (8%) than with normal SB (4.1%) (hazard ratio [HR], 2.8; 95% confidence interval [CI], 1.5–5.3; p = .001, IPTW‐adjusted) or SB lesions <10 mm (5.1%) (HR, 1.5; 95% CI, 1.1–3.3; p = .048, IPTW‐adjusted), being similar between these last two groups.ConclusionsIn bifurcation PCI, SB lesion length ≥ 10 mm identifies patients at higher risk of MACE than those with <10 mm SB lesions and those without SB disease, considering that no differences were observed among these last two groups. Careful planning is mandatory when approaching bifurcations with long SB lesions.
