Background: Many studies have demonstrated that deferral of percutaneous coronary intervention (PCI) on the basis of a myocardial fractional flow reserve (FFR) ≥0.75 is associated with a very low coronary event rate. However, some groups have empirically chosen the cut-off value of 0.80 rather than 0.75 for decision to defer PCI and the FFR measurement between 0.75 and 0.80 has been established as a grey zone. The aim of this study was to evaluate the long-term clinical outcomes of patients with moderate coronary lesions and FFR measurements between 0.75 and 0.80. Methods: The study included 125 anigiographically moderate coronary lesions (>50% diameter stenosis by visual assessment) in 125 patients but in whom the PCI was deferred on the basis of an FFR ≥ 0.75. The FFR was calculated as the ratio of mean distal pressure divided by the proximal pressure during hyperemia. Patients were divided into two groups according to the result of FFR: ≥ 0.80 (n=99, group 1) and between 0.75 and 0.79 (n=26, group 2). We evaluated the long-term major adverse cardiovascular events (MACE) related and unrelated to the FFR-evaluated lesion. Results: During a follow-up period of 82 ± 29 months (mean ± SD), The Kaplan-Meier event-free survival curves showed that group 2 was poorer than group 1 in prognosis (p=0.0148). The incidence of MACE unrelated FFR-evaluated lesion in group 1 was equivalent to that in group 2 (p=0.96). Conclusions: In patients with moderate coronary lesions and borderline FFR measurements, deferral of PCI was associated with a higher rate of MACE related to the FFR-evaluated lesion. FFR cut-off point of 0.80 instead of 0.75 may be more appropriate for deferring PCI.

Calcified Coronary Lesions

Despite advances in technology, percutaneous coronary intervention (PCI) of severely calcified coronary lesions remains challenging. Rotational atherectomy is one of the current therapeutic options to manage calcified lesions, but has a limited role in facilitating the dilation or stenting of lesions that cannot be crossed or expanded with other PCI techniques due to unfavourable clinical outcome in long-term follow-up. However the results of orbital atherectomy presented in the ORBIT I and ORBIT II trials were encouraging. In addition to these encouraging data, necessity for sufficient lesion preparation before implantation of bioresorbable scaffolds lead to resurgence in the use of atherectomy. This article summarises currently available publications on orbital atherectomy (Cardiovascular Systems Inc.) and compares them with rotational atherectomy.

Background: The treatment of LMCAD has shifted from coronary artery bypass grafting (CABG) to Percutaneous coronary intervention (PCI). However, data on long-term outcomes of PCI for LMCA disease, especially in patients with acute coronary syndrome (ACS) remains limited and conicting. This study aims to nd the association of the immediate and 4-year mortality in ACS patients with LMCA disease treated by PCI based on ejection fractions at admission. Methods: A retrospective analytical study was conducted. Patients were divided at admission into those with reduced left ventricular ejection fraction and those with preserved ejection fraction. Results: Forty (58.8%) of the patients presented with preserved EF. The mean age of the patients was 71.6±7.1 years. The mean LVEF of the preserved group was 61.6±4.3% and signicantly higher than that of the reduced group. Age and cardiovascular risk factor prole was similar between the two groups. Patients with reduced ejection fraction had signicantly higher levels of serum creatinine and signicantly lower levels of Hb and HDL. Mean hospital stay was signicantly longer for patients with preserved EF. In-hospital deaths were also similar between the two groups. The reduced EF group had a signicantly higher allcause mortality in the 4-year follow-up period. The mean years of follow-up for all participants was 4.2±1.3 years. Conclusion: It was seen that in patients presenting with ACS and undergoing PCI due to LMCAD, LVEF at admission, singly and in in multivariate regression is an important predictor of in hospital and 4-year mortality

Abstract Objectives: This study analyzed the association between on-treatment platelet reactivity and long-term outcomes of patients with acute coronary syndrome (ACS) and thrombocytopenia (TP) in the real world. Methods: A total of 10724 consecutive cases with coronary artery disease who underwent percutaneous coronary intervention (PCI) were collected from January to December 2013. Cases with ACS and TP under dual anti-platelet therapy were enrolled from the total cohort. 5-year clinical outcomes were evaluated among cases with high on-treatment platelet reactivity (HTPR), low on-treatment platelet reactivity (LTPR) and normal on-treatment platelet reactivity (NTPR), tested by thromboelastogram (TEG) at baseline. Results: Cases with HTPR, LTPR and NTPR accounted for 26.2%, 34.4% and 39.5%, respectively. Cases with HTPR were presented with the most male sex, lowest hemoglobin level, highest erythrocyte sedimentation rate and most LM or three-vessel disease, compared with the other two groups. The rates of 5-year all-cause death, major adverse cardiovascular and cerebrovascular events (MACCE), cardiac death, myocardial infarction (MI), revascularization, stroke and bleeding were all not significantly different among three groups. Multivariable Cox regression indicated that, compared with cases with NTPR, cases with HTPR were not independently associated with all endpoints, as well as cases with LTPR (all P>0.05). Conclusions: In patients with ACS and TP undergoing PCI, 5-year all-cause death, MACCE, MI, revascularization, stroke and bleeding risk were all similar between cases with HTPR and cases with NTPR, tested by TEG at baseline, in the real world. The comparison result was the same between cases with LTPR and NTPR.
