Coronary artery aneurysm is uncommon and mostly caused by coronary atherosclerosis. Although usually asymptomatic, it may cause catastrophes due to aneurysm rupture, vasospasm, or thromboembolism formation. Coronary artery aneurysm most frequently involves the right coronary artery, followed in frequency by the left circumflex coronary artery and the left anterior descending coronary artery; it rarely involves the left main coronary artery. Herein present two cases with left main coronary artery aneurysm and briefly discuss their treatment. 相似文献

Very high takeoff of the left main coronary artery in the absence of another coronary anomaly is a rare finding. The pathologic consequences of this anomaly are unclear, and the literature on this subject does not agree on whether the condition is dangerous. We present our findings in 2 patients who were discovered to have this anomaly upon noninvasive computed tomographic coronary angiography, and we discuss our analysis of the literature and our management of these patients. 相似文献

The choice between coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for myocardial revascularization in patients with left main disease (LMD) is controversial. There is general agreement that CABG is appropriate for all patients, and PCI is acceptable for those with low-to-intermediate anatomic complexity. However, there is uncertainty about the relative safety and efficacy of PCI in patients with more complex LMD and with comorbidities such as diabetes. No direct comparison trial has focused on revascularization in diabetic patients with LMD, and thus conclusions on the topic are subject to the limitations of subgroup analysis, as well as the heterogeneous exclusion criteria, and methodologies of individual trials. The available evidence suggests that among diabetics, CABG is superior in patients with LMD with SYNTAX (SYNergy between percutaneous coronary intervention with TAXus and dardiac surgery) score greater than 33, distal bifurcation disease, or multivessel disease. PCI may be appropriate in those with less-extensive disease or those with limited life expectancy or high surgical risk. 相似文献

Background
Limited data are available on the relative performances between different types of drug-eluting stents (DES) for obstructive left main coronary artery disease (LMCAD).Objectives
This study sought to compare effectiveness and safety profiles of various second-generation DES for LMCAD in real-world clinical practice.Methods
Among 4,470 patients in 3, multicenter, prospective registries (IRIS-DES [Interventional Cardiology Research Incorporation Society-Drug-Eluting Stents] registry, the IRIS-MAIN [Interventional Cardiology Research Incorporation Society-Left MAIN Revascularization] registry, and the PRECOMBAT [PREmier of Randomized COMparison of Bypass Surgery versus AngioplasTy Using Drug-Eluting Stent in Patients with Left Main Coronary Artery Disease] study) treated between July 2007 and July 2015, the authors identified 2,692 patients with significant LMCAD who received second-generation DES; 1,254 with cobalt-chromium everolimus-eluting stents (CoCr-EES), 232 with biodegradable polymer biolimus-eluting stents (BP-BES), 616 with platinum-chromium EES (PtCr-EES), and 590 with Resolute zotarolimus-eluting stent (Re-ZES). The primary outcome was target-vessel failure.Results
The observed 3-year rates of target-vessel failure were not significantly different for the different types of DES (16.7% for the CoCr-EES, 13.2% for the BP-BES, 18.7% for the PtCr-EES, and 14.7% for the Re-ZES; p = 0.15). In multiple treatment propensity score analysis, the adjusted hazard ratios (HRs) for target-vessel failure were similar in between-group comparisons of the different DES, except for the PtCr-EES versus the BP-BES (reference; HR: 1.60; 95% confidence interval: 1.01 to 2.54; p = 0.046). There were no significant differences in risk of composite of all-cause death, any myocardial infarction, or any revascularization and its individual components according to the different types of DES. Although the 3-year incidence of stent thrombosis was considerably low (≤1.0%) for all types of DES, between-group differences were observed, generally favoring the EES platforms.Conclusions
In this pooled analysis of 3 prospective registries involving unrestricted use of various second-generation DES for LMCAD, we found no significant between-group differences in 3-year risk of target-vessel failure, except for a higher risk of primary outcome with PtCr-EES compared to BP-BES.

Giant aneurysm of the left main coronary artery is exceedingly rare and accounts for less than 2% of patients undergoing coronary angiography. The etiology varies depending on the patient''s age and geographic area, but half are of atherosclerotic origin. In most cases, coronary aneurysms are asymptomatic, however, symptomatic patients present with symptoms characteristic of coronary artery disease such as chest pain (angina pectoris), myocardial infarction, congestive heart failure, and even sudden death. Coronary angiography is considered the gold standard tool to determine the presence or absence of coronary artery disease, and if present, its size and location. Herein, we report a case of giant aneurysm of the left main coronary artery presenting as syncope and documented nonsustained ventricular tachycardia. 相似文献
