Left ventricular thrombus is a frequent complication after myocardial infarction and is associated with high risk for arterial embolic complications. In addition to oral anticoagulation, surgical thrombectomy may be a promising treatment for large and mobile thrombus. We report the rare case of a 27-year-old patient who presented with a giant left ventricular thrombus after expanded and silent myocardial infarction caused by spontaneous dissection of the left anterior descending coronary artery. As conservative therapy by oral anticoagulation had failed, the thrombus was removed by performing left ventriculotomy...

OBJECTIVES: To review the effectiveness of manual thrombectomy (MT) in a series of patients with ST-elevation myocardial infarction (STEMI) exclusively presenting with TIMI 0-1 flow undergoing percutaneous coronary intervention (PCI), in accordance to the angiographically estimated area at risk (AAR). Second, to assess major in-hospital clinical events, emphasizing neurological outcomes. BACKGROUND: The routine utilization of MT in STEMI is not recommended. However, in recent trials, a significant proportion of patients had neither large thrombus burden nor a totally occluded coronary segment, neutralizing the expected benefits of MT...

BACKGROUND: The treatment method for acute ischemic stroke is rapidly developing, and the effects of endovascular modalities, when used alone or in combination, needs to be studied. We aimed to identify the difference between pharmaceutical thrombolysis and multi-modal therapy (MMT) used in acute posterior circulation ischemic stroke (APCIS) patients and also to detect the predictors for successful recanalization and favorable outcomes. METHODS: A retrospective analysis of patients with APCIS who received thrombolytic pharmaceuticals and MMT from 2011 to 2016 was performed at the stroke center...

A 52-year-old Asian male with no traditional risk factors for coronary artery disease presented with acute coronary syndrome. Coronary angiography showed complete thrombotic occlusion of the left circumflex with a large thrombus burden in the setting of diffuse aneurysmal enlargement of the coronary arteries consistent with antecedent Kawasaki disease. Manual thrombectomy with adjunctive intracoronary tirofiban was performed utilizing the GuideLiner catheter. Stent implantation was deferred. Follow-up imaging 48 h later showed preserved coronary flow and decreased thrombus burden...

RATIONALE: Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries. CAE is often associated with the presence of slow coronary flow and may lead to acute myocardial infarction (AMI), even without total occlusion. PATIENT CONCERNS AND DIAGNOSIS: We report a case of a 24-year-old male patient with CAE suffering from AMI. INTERVENTIONS: Percutaneous coronary intervention with aspiration thrombectomy failed to restore adequate blood flow...

Previous study has demonstrated that erythrocyte-rich thrombi contain more inflammatory cells and reflect high thrombus burden, leading to impaired myocardial reperfusion in myocardial infarction. The aim of this study is to investigate the utility of quantified frequency domain optical coherence tomography (FD-OCT) signal analysis in evaluating the erythrocyte-rich thrombus with ex-vivo materials. We evaluated 54 specimens of coronary artery thrombus obtained by thrombectomy catheter from 8 patients who underwent primary percutaneous coronary intervention...

BACKGROUND: Thrombus aspiration during percutaneous coronary intervention (PCI) for the treatment of ST-segment-elevation myocardial infarction (STEMI) has been widely used; however, recent trials have questioned its value and safety. In this meta-analysis, we, the trial investigators, aimed to pool the individual patient data from these trials to determine the benefits and risks of thrombus aspiration during PCI in patients with ST-segment-elevation myocardial infarction. METHODS: Included were large (n≥1000), randomized, controlled trials comparing manual thrombectomy and PCI alone in patients with ST-segment-elevation myocardial infarction...

BACKGROUND: Drug-eluting stent (DES) -induced coronary vasospasm is a well known phenomenon after stent implantation; however, the extent of this risk is still unknown. We report a case in which DES-induced severe coronary vasospasm was clinically suspected as a cause of subacute stent thrombosis (ST). CASE PRESENTATION: A 67-year-old man came to our hospital due to chest pain with mild exercise. He was diagnosed with effort angina by coronary angiography and underwent DES implantation in the mid-left ascending artery (LAD) after the administration of dual anti-platelet therapy...

OBJECTIVES: Hepcidin-25 serves as a key peptide in the regulation of iron homeostasis and inflammation. It remains unknown whether hepcidin-25 plays an adverse role in atherosclerotic diseases. The aim of this study was to investigate whether hepcidin-25 is involved in the pathophysiology of coronary plaque vulnerability. METHODS AND RESULTS: Serum hepcidin-25 levels were quantitatively determined by the LC-MS/MS assay system. Peripheral blood was collected from patients with acute myocardial infarction (MI, n=33) and patients with stable angina pectoris (sCAD, n=19)...

Limited data exist on the association between breast cancer treatments and coronary artery disease anatomy, particularly in males. We describe an unusual case of diffuse coronary ectasia in a man with breast cancer presenting with acute coronary syndrome (ACS). A 66-year-old man with breast cancer on paclitaxel, tamoxifen, and carboplatin chemotherapy regimen, presents with new onset chest pain. Electrocardiogram reveals anterolateral ST-segment depressions and elevated troponin I level. Emergent angiography revealed grossly ectatic coronary arteries with a total thrombotic occlusion of the mid right coronary artery...

Right Heart Thrombus (RiHT) management is really controversial, and appropriate guidelines are not present for the management. In patients referring with RiHT and Pulmonary Embolism (PE), there are three ways of managing these patients. Out of the three, one is thrombectomy, which is with high risk taking in mind the comorbidities these patients have. The other is using thrombolytic which, in many cases is contraindicated or with high risk. The other less effective way is full anticoagulation. It is really controversial to choose between these ways of management and no clear approach is present...

Computed tomographic angiography (CTA) is a quick and accurate method in triage to determine recanalization therapies for acute ischemic stroke. To minimize delay in the start of recanalization therapies, performance of CTA immediately after unenhanced brain computed tomography (CT) is recommended as the minimum standard. However, there are some pitfalls related to image interpretation of CTA in acute stroke, such as false patency sign. We describe the case of a 66-year-old man who presented with acute middle cerebral artery (MCA) occlusion by a calcified embolus with false patency sign on CTA after coronary angiography...

OBJECTIVES: The aim of this study was to evaluate if residual thrombus burden after aspiration thrombectomy affects the outcomes of primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND: Recent studies failed to show clinical benefit of aspiration thrombectomy in STEMI patients. This might be due to insufficient removal of thrombus at the culprit lesion. METHODS: A total of 109 STEMI patients who underwent aspiration thrombectomy followed by stenting within 24 h from symptom onset were included...

INTRODUCTION: Coronary artery aneurysm (CAA) is defined as coronary dilatation which exceeds the diameter of the normal adjacent artery segments or the diameter of the patient's largest coronary artery by 1.5 times. The incidence of giant CAA is difficult to be determined, since only few reports have been described in the literature. METHODS AND RESULTS: A 65-year-old man was referred to our hospital because of a "mass" in the right heart detected on echocardiography at a regular medical health examination, while he experienced no any symptoms...

OBJECTIVE: To investigate whether angiographically defined occlusion type could predict of the etiology of acute intracranial large artery occlusion and the stentriever response. METHODS: We reviewed consecutive patients with acute intracranial large artery occlusion who underwent endovascular treatment and examined their workups for embolic sources. Patient demographics, laboratory findings, hyperdense artery sign, and angiographic occlusion type (truncal-type or branching-site occlusion) were compared between embolic sources (+) and (-) groups...
