PATIENT Male, 74 FINAL DIAGNOSIS: Abdominal aortic aneurysm (AAA) Symptoms: Palpable abdominal mass Medication: - Clinical Procedure: Abdominal aortic aneurysm repair Specialty: Surgery. OBJECTIVE Rare disease. BACKGROUND Coronary artery disease is common in elderly patients with abdominal aortic aneurysms. Here we report a case of the combination of surgical repair for abdominal aortic ane...

BACKGROUND Provisional stenting is effective for anatomic simple bifurcation lesions. Double kissing crush stenting reduces the 1-year rate of target lesion revascularization. This study aimed to investigate the 5-year clinical results of the DKCRUSH-II study (Randomized Study on Double Kissing Crush Technique Versus Provisional Stenting Technique for Coronary Artery Bifurcation Lesions). MET...

Percutaneous coronary intervention carries the risk of coronary artery perforation, which may lead to serious adverse effects such as cardiac tamponade, myocardial infarction, and even death. We describe a patient who developed hemoptysis immediately after saphenous vein graft rupture, which is a rare complication during coronary intervention. Stenting using a covered stent, along with simultan...

Coronary artery thrombosis, due either fissuring or erosion of atherosclerotic plaque, is the usual cause of acute myocardial infarction (1) and results in a progressive increase of the infarct size with a wavefront transmural extension from the endocardium towards the epicardium (2,3). Although thrombolysis and reperfusion can occur spontaneously, thrombotic coronary artery occlusion usually p...

Objective: We evaluated the short and long-term effect of peri-interventional dabigatran therapy on vasomotion, endothelialization, neointimal formation in a porcine coronary artery stenting model. Background: Stenting arteries induces local inflammation, impairs vasomotion delays endothelialization. Methods: Twenty-eight animals underwent percutaneous intervention (PCI) with drug eluting stent...

Perioperative acute myocardial infarction (AMI) is the most common cause of postoperative morbidity and mortality. It is a rare but important and fatal complication. Recognizing this situation may be difficult due to the influence of general anesthesia. Early diagnosis and treatment can decrease the morbidity and mortality of this fatal complication. In this case we present a 56-year-old female...

Carotid arterial dissections may result from spontaneous or traumatic causes. Postcoital arterial dissections have been reported in both the vertebral and coronary arteries. We report a rare case of spontaneous dissection from the common carotid artery to the internal and external carotid arteries after sexual intercourse, leading to fulminant middle cerebral artery (MCA) territory infarct. Alt...

OBJECTIVES The study compared the safety and efficacy of coronary artery stenting in aged and nonaged patients and identified predictors of adverse clinical outcomes. BACKGROUND Limited data are available on the outcomes of stenting in the aged (> or = 80 years) compared to nonaged patients. METHODS The study was a pooled analysis of 6,186 patients who underwent coronary artery stenting in ...

BACKGROUND The association of shear stress (SS) with in-stent restenosis after bare metal stenting is not clear. We investigated the significance of SS on predicting areas with neointima thickness (NT) in humans and the effect of vascular brachytherapy (VBT) following coronary artery stenting on the relationship of SS with NT. METHODS By using coronary angiography and intravascular ultrasound...

BACKGROUND Coronary stents, drug-eluting stents in particular, have been linked to coronary epicardial endothelial dysfunction after implantation. However, less is known about their impact on coronary microvascular function and their long-term effects on the vasculature. METHODS AND RESULTS We evaluated 71 patients (mean age, 53.0±10.1 years) with chest pain and angiographically nonsignifican...
