BACKGROUND: It is not entirely clear whether ischemia burden on stress single-photon emission computed tomography (SPECT) effectively identifies patients who have a long-term benefit from coronary revascularization. METHODS: The study population consisted of 719 patients with ischemia on stress SPECT. Early coronary revascularization was defined as percutaneous coronary intervention or coronary artery bypass grafting ≤90 days after SPECT. Patients who underwent late revascularization (>90 days after SPECT) were excluded (n = 164)...

BACKGROUND: Current guidelines suggest that coronary artery bypass grafting (CABG) should be the preferred revascularization method for unprotected left main coronary artery stenosis. In light of evidence from recent randomized trials, we assessed whether percutaneous coronary intervention (PCI) using drug-eluting stents is as safe and effective as CABG for the treatment of unprotected left main coronary artery disease. METHODS AND RESULTS: Digital databases and manual searches were performed for randomized trials comparing PCI and CABG for unprotected left main coronary artery stenosis...

BACKGROUND: Kidney transplantation is the definite surgical treatment for end-stage renal disease. Shortage of organs and the increasing number of patients with end-stage renal disease has led to an expansion of the selection criteria promoting the use of organs from marginal donors. Use of kidneys with renal artery aneurysm (RAA) is one such example. Description of the case: We report a case of living-related kidney transplantation from a 46-year-old female donor with unilateral RAA to her 68-year-old father...

Masahiro Koide, Keiji Inoue, Akiko Matsuo, Hiroshi Fujita
BACKGROUND: Heavy coronary artery calcification is responsible for stent underexpansion, which is associated with increased in-stent restenosis. Here we report a case in which optical coherence tomography (OCT) demonstrated that the metal component of an underexpanded stent previously implanted in a heavy calcified lesion had been completely removed after ablation with rotational atherectomy. CASE PRESENTATION: An 83-year-old man with exertional angina was referred to our hospital...

AIMS: Despite optimal angiographic results after percutaneous coronary intervention (PCI), some lesions may continue to produce ischemia under maximal hyperemia. We evaluated the factors associated with persistently ischemic fractional flow reserve (FFR) after angiographically successful PCI. METHODS AND RESULTS: A total of 574 consecutive patients with 664 lesions undergoing PCI who had FFR pre- and post-PCI were analyzed. Percutaneous coronary intervention led to effective ischemia reduction from pre-FFR (0...

The Crosser catheter is a unique device that facilitates antegrade intraluminal recanalization by high-frequency vibration energy and cavitation. We used this device not only as a chronic total occlusion (CTO) crossing device, but also as a flossing device in stenotic lesions and we also evaluated the efficacy of this device when used with both the "Crosser preceding" and the "Guidewire preceding" in CTOs. Complications related to this device were investigated, too. We retrospectively analyzed a total of 90 consecutive patients with peripheral artery disease in the femoropopliteal artery and below-the-knee artery (BTA)...

BACKGROUND: Coronary vasospasm is an important pathogenesis of acute coronary syndrome (ACS). However, the clinical features and prognosis of vasospastic angina (VA) patients presenting with ACS (VAACS) are still unclear. We aimed to evaluate the clinical characteristics and long-term outcomes of VAACS patients without significant coronary artery stenosis. METHODS AND RESULTS: A total of 986 VA patients confirmed by ergonovine provocation test were analyzed. VAACS was defined as VA patients visiting the emergency room with documented electrocardiographic changes, significant arrhythmias, or elevated cardiac biomarkers...

OBJECTIVE: Angiographic assessment of stenosis has limited predictive value for functionally significant lesions compared with fractional flow reserve (FFR). The recently developed angiographic DILEMMA score, which consists of minimal lumen diameter (MLD), lesion length (LL) and Bypass Angioplasty Revascularization Investigation (BARI) Myocardial Jeopardy Index (MJI) was found to have diagnostic value in predicting FFR ≤0.80. The present study was an investigation of prediction of FFR ≤0...

BACKGROUND: The drug-eluting balloon (DEB) is a promising tool to prevent restenosis after coronary angioplasty. However, data on the outcomes of DEB in de novo lesions are scarce. Vessel recoil and constrictive remodeling are the dominant causes of restenosis after angioplasty. The use of cutting balloons (CB) may effectively reduce elastic recoil after balloon dilation. In this study, we evaluate the efficacy and safety of DEB in treating de novo coronary artery lesions, using a predilation strategy with cutting balloon (CB) dilation before DEB angioplasty...

BACKGROUND: Patients with known coronary artery disease presenting to the emergency department (ED) with chest pain are often admitted, yet may not be having an acute coronary syndrome (ACS). METHODS: We assessed whether the use of a novel risk score and a modified thrombolysis in myocardial infarction risk score obtained in the ED could discriminate which of these high-risk patients have ACS. Chart review was performed on a cohort of 285 patients with known coronary artery disease presenting to the ED with chest pain thought to be of ischemic origin and admitted to the hospital...
