coronary thrombectomy

BACKGROUND: Renal cell carcinoma accounts for 2-3% of all malignant cancers in adults and is characterized by the potential development of venous tumor thrombus. CASE PRESENTATION: We present a rare case of a 62-year-old Caucasian man who arrived in the emergency department for monosymptomatic hematuria. Further investigation revealed a right renal cell carcinoma with 16 cm intravascular extension through the renal vein into the inferior vena cava and right atrium associated with significant coronary artery disease based on the computed tomography scan and coronary angiography...

PURPOSE OF REVIEW: To review the evidence regarding stroke and recent myocardial infarction (MI), reduced left ventricular ejection fraction, left ventricular thrombus (LVT), and wall motion abnormalities (WMA). RECENT FINDINGS: The risk of ischemic stroke associated with acute MI has been greatly reduced with reperfusion treatments that improved myocardium salvage. Acute ischemic stroke is an uncommon complication of diagnostic coronary angiography and percutaneous coronary intervention...

BACKGROUND: Despites guidelines and strong evidence supporting intravenous thrombolysis and endovascular thrombectomy for acute stroke, access to these interventions remains a challenge. The objective of the IMPROVE stroke care program was to accelerate acute stroke care delivery by implementing best practices and improving the regional systems of care within comprehensive stroke networks. METHODS: The IMPROVE Stroke Care program was a prospective quality improvement program based on established models used in acute coronary care...

In recent years, A Direct Aspiration First Pass Technique (ADAPT) has emerged as an effective and safe method of thrombectomy. Large trials have shown noninferiority of ADAPT compared to primary stent retriever approach, while new studies emphasize on its shorter procedural time with potentially fewer complications and costs.1,2 . Failure of the A Direct Aspiration First Pass Technique (ADAPT) is often due to the inability to successfully navigate the aspiration catheter to the thrombus site. As a solution, several techniques have been considered such as the use of stiffer microcatheters or a wedge device...

BACKGROUND: Coronary artery embolism caused by BioGlue is a rare complication; therefore, its diagnosis and treatment remain undefined. CASE SUMMARY: A 47-year-old woman underwent ascending aortic replacement and coronary artery bypass grafting (CABG) for type A acute aortic dissection involving the right coronary artery ostium in 2017. Subsequently, she was diagnosed with Marfan syndrome. Five years later in 2022, she underwent aortic arch replacement, the Bentall procedure, and repeat CABG because of aortic root enlargement and aortic regurgitation progression...

BACKGROUND: Previous reports have revealed various endovascular intervention techniques for prosthetic femoropopliteal bypass occlusion (PFPBO); however, treatment for PFPBO remains challenging for most interventionalists and vascular surgeons because the procedure is complicated. Most of the reported techniques involve device implantation. In the present study, we performed a combination of surgical graft thrombectomy and drug-coated balloon angioplasty for PFPBO without implanting any additional devices...

Background: Compelling evidence has accumulated on the role of oxidative stress on the endothelial cell (EC) dysfunction underlying acute coronary syndrome. However, unveiling the underlying metabolic determinants has been hampered by the scarcity of appropriate cell models to address cell-autonomous mechanisms of ED dysfunction. Methods: We have generated endothelial cells derived from thrombectomy specimens from patients affected with acute myocardial infarction (AMI) and conducted phenotypical and metabolic characterization, focused on central carbon metabolism...

BACKGROUND: Tirofiban is an antiplatelet treatment approved for acute coronary syndrome, but it has not been rigorously evaluated for efficacy and safety in patients with acute ischemic stroke (AIS) treated with endovascular thrombectomy (EVT). METHODS: Electronic databases were systematically searched for studies conducted from January 1, 2015, to July 31, 2021, that evaluated tirofiban administration for patients with AIS treated with EVT in comparison with control...

We present a 73-year-old female with history of rheumatic heart disease status post-mechanical mitral valve on warfarin, valvular atrial fibrillation, and alpha thalassemia who was admitted to an outside hospital with anterior ST-segment myocardial infarction. Coronary angiogram showed occluded left anterior descending artery (LAD) with acute thrombus status post-thrombectomy and balloon angioplasty.

Coronary microvascular dysfunction (CMD) is a common complication of ST-segment elevation myocardial infarction (STEMI) and can lead to adverse cardiovascular events. This is a non-randomized, observational, prospective study of STEMI patients with multivessel disease who underwent primary PCI, grouped based on whether they underwent balloon pre-dilatation stenting or direct stenting of the culprit lesion. Coronary physiology measurements were performed 3 months post-PCI including coronary flow reserve (CFR) and index of microcirculatory resistance (IMR) measurements at the culprit vessel...

Background : Acute ischemic stroke (AIS) following left ventricular assist device (LVAD) implantation is a serious complication associated with device morbidity. AIS development following LVAD placement typically presents between 6- and 24-months post implantation. Case/Results : We report a case of a 67-year-old male who initially presented with reduced ejection fraction and severe coronary vessel disease. Following coronary artery bypass graft surgery, the patient remained in a low output state necessitating placement of an LVAD device...

INTRODUCTION: ST-segment elevation myocardial infarction (STEMI) with high thrombus burden is associated with a poor prognosis. Manual aspiration thrombectomy reduces coronary vessel distal embolisation, improves microvascular perfusion and reduces cardiovascular deaths, but it promotes more strokes and transient ischaemic attacks in the subgroup with high thrombus burden. Intrathrombus thrombolysis (ie, the local delivery of thrombolytics into the coronary thrombus) is a recently proposed treatment approach that theoretically reduces thrombus volume and the risk of microvascular dysfunction...

BACKGROUND: A silent left ventricular thrombus is dangerous. The current standard anticoagulation therapy was ineffective in our case or similar, and the outcome was poor. CASE PRESENTATION: A 33-year-old man with a silent left ventricular thrombus was detected incidentally by transthoracic echocardiography. After admission, anti-coagulation with low-molecular-weight heparin therapy was carried out. The CAG revealed 70% systolic stenosis in the middle of the right coronary artery along with myocardial bridging...

BACKGROUND: Coronary air embolism (CAE) is a rare and life-threatening complication of endovascular procedures, mostly due to procedure-related causes. CASE SUMMARY: A 70-year-old man with severe respiratory disorder presented with patent foramen ovale (PFO)-related platypnea-orthodeoxia syndrome (POS). Transcatheter PFO closure was performed under local anaesthesia and intracardiac echocardiographic guidance. After a 5-Fr catheter was passed through the PFO via a 7-Fr femoral vein sheath, the patient suddenly coughed and breathed deeply...

BACKGROUND: Left ventricular (LV) thrombus is a lethal complication of coronary artery disease that can lead to embolization and sudden death. There is no clear consensus on the optimal treatment for LV thrombi. There is a paucity of case series about surgical excision of LV thrombus in patients with coronary vessel disease. For that, there is insufficient evidence to support surgical excision of LV thrombus and recommend the optimal timing of this procedure. CASE SUMMARY: We report a case of a 52-year-old man with a history of percutaneous catheter intervention for mid-right coronary artery lesion 3 years ago...

BACKGROUND: We present the case of an individual with acute occlusion of the middle cerebral artery caused by atherosclerosis. The patient underwent angioplasty using a coronary perfusion balloon, which resulted in a favorable clinical outcome. CASE DESCRIPTION: A 66-year-old male patient presented with an acute onset of right hemiplegia and dysarthria. Magnetic resonance imaging revealed an occlusion of the left middle cerebral artery, and alteplase was administered, followed by a mechanical thrombectomy and intracranial balloon catheter angioplasty...

BACKGROUND: We explored the potential of mechanical thrombectomy (MT) for acute ischemic stroke patients at hospitals that perform percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) in the United States. METHODS: We analyzed nationally representative data between 2017 and 2020 to determine the numbers, characteristics, and outcomes of acute ischemic stroke patients admitted to hospitals that perform both primary PCI and MT, hospitals that perform primary PCI but not MT and hospitals that perform neither PCI or MT...

PURPOSE: Pediatric liver transplant surgery is burdened by arterial complications whose endovascular treatment is not standardized. We report the outcomes of a cohort of pediatric recipients with hepatic artery complications treated by endoluminal procedures. MATERIALS AND METHODS: From December 2019 to December 2022, consecutive transplanted pediatric patients who underwent endovascular treatment of hepatic artery complications were reviewed. The analysis included: type of complication (occlusion, stenosis, pseudoaneurysm); onset (acute =  < 15 days, subacute = 15-90 days, late =  > 90 days); endovascular technique (angioplasty, stenting); complications and outcomes...

Acute ST-elevation myocardial infarction (STEMI), acute ischemic stroke (AIS), and acute pulmonary embolism (PE) are life-threatening conditions, each posing a high risk of morbidity and mortality. When all three of these acute conditions occur simultaneously, the overall prognosis for the patient becomes considerably worse. We report a case of a 70-year-old woman who presented to the emergency department (ED) with a triad of acute STEMI, AIS, and PE as a consequence of atherosclerotic heart disease, atrial fibrillation, and a prolonged transatlantic flight...
