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...

With increasing use of left ventricular assist devices (LVAD) for long-term circulatory support comes a growing need for device exchange. The conventional surgical approach for device exchanges has been a reoperative median resternotomy. Less invasive HeartMate II LVAD exchange via a non-muscle-dividing subxiphoid incision as an alternative to a left subcostal incision may reduce pain burden and facilitate recovery. From November 2006 through June 2015, 292 patients underwent HeartMate II LVAD placement, of which 30 (10...

Chronic thromboembolic pulmonary hypertension (CTEPH) represents a unique subtype of pulmonary hypertension characterized by the presence of mechanical obstruction of the major pulmonary vessels caused by venous thromboembolism. CTEPH is a progressive and devastating disease if not treated, and is the only subset of PH potentially curable by a surgical procedure known as pulmonary endarterectomy. The clot burden and pulmonary embolism recurrence may contribute to the development of CTEPH however only few thrombophilic factors have been found to be associated...

BACKGROUND: -Thrombus aspiration during percutaneous coronary intervention (PCI) for the treatment of ST 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 STEMI. METHODS: -Included were large (N≥1000) randomized controlled trials comparing manual thrombectomy vs...

BACKGROUND: Abdominal aortic aneurysm (AAA) wall inflammation and mechanical structural stress may influence AAA expansion and lead to rupture. We hypothesized a positive correlation between structural stress and fluorine-18-labeled 2-deoxy-2-fluoro-d-glucose ((18)F-FDG) positron emission tomography-defined inflammation. We also explored the influence of computed tomography-derived aneurysm morphology and composition, including intraluminal thrombus, on both variables. METHODS AND RESULTS: Twenty-one patients (19 males) with AAAs below surgical threshold (AAA size was 4...

Deep vein thrombosis (DVT) is associated with a high cost burden for health care systems because of secondary cost intensive complications like pulmonary embolism and especially the post thrombotic syndrome (PTS). The current standard therapy of anticoagulation for DVT therapy has not changed through the years leaving patients especially with iliofemoral vein thrombus on a high-risk situation for developing PTS. Current study situation for endovascular treatment of iliofemoral DVT treatment gives a rationale for active thrombus removal using catheter directed therapy (CDT) or pharmacomechanical thrombectomy (PMT) which improves valvular vein function and luminal patency reducing the potential complication of PTS...

Background. Insufficient data are available on the potential benefit of selective aspiration and clinical predictors for no-reflow in STEMI patients undergoing primary percutaneous coronary intervention (PPCI) adjunct with aspiration thrombectomy. Objective. The aim of our study was to investigate clinical predictors for insufficient reperfusion in patients with high thrombus burden treated with PPCI and manual aspiration thrombectomy. Methods. From January 2011 till December 2015, 277 STEMI patients undergoing manual aspiration thrombectomy and PPCI were selected and 202 patients with a Thrombolysis in Myocardial Infarction (TIMI) thrombus grade 4~5 were eventually involved in our study...

This study aims to evaluate occurrence, size, composition, and clinical significance of embolized debris during superficial femoral artery atherectomy using all commercially available atherectomy devices. Distal athero/thromboembolic events (DATE) are a universal phenomenon in lower extremity atherectomy procedures (LEAPs) due to the sheer volume of atheroma and the thrombus burden in peripheral arterial disease. Some of these events can be clinically significant. We prospectively gathered clinical and histopathological data on all commercially available atherectomy devices by using embolic protection devices (EPD) in every case...

AIMS: Restoration of effective myocardial reperfusion by primary percutaneous coronary intervention (PPCI) in patients with ST-elevation myocardial infarction is difficult to predict. A method to assess the likelihood of a suboptimal response to conventional pharmacomechanical therapies could be beneficial. We aimed to derive and validate a scoring system that can be used acutely at the time of coronary reopening to predict the likelihood of downstream microvascular impairment in patients with STEMI...

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...

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an independent risk factor for plaque rupture and atherothrombotic events. However, the associations between serum Lp-PLA2 level and thrombus burden in ST-segment elevation myocardial infarction (STEMI) patients remain unknown.We consecutively enrolled 351 STEMI patients who underwent primary percutaneous coronary intervention (pPCI). Patients were assigned to a high thrombus burden (HTB) group (n = 230) and a low thrombus burden (LTB) group (n = 121). Baseline data were recorded during hospital admission...

Lindsay Robertson, Olivia McBride, Anne Burdess
BACKGROUND: Deep venous thrombosis (DVT) occurs in approximately one in 1000 adults every year, and has an annual mortality of 14.6%. In particular, iliofemoral DVT can lead to recurrent thrombosis and post-thrombotic syndrome (PTS), a painful condition which can lead to chronic venous insufficiency, oedema, and ulceration. It causes significant disability, impaired quality of life, and economic burden. Early thrombus removal techniques have been advocated in patients with an iliofemoral DVT in order to improve vein patency, prevent valvular dysfunction, and reduce future complications, such as post-thrombotic syndrome and venous ulceration...

BACKGROUND AND PURPOSE: As previously demonstrated, the recanalization rate and clinical outcome in patients with anterior circulation stroke treated with IV thrombolysis (IVT) depend on clot characteristics such as thrombus length and thrombus density. In patients with basilar artery occlusion (BAO) treated with IVT, the recanalization rate has also been shown to depend on thrombus length, although no cut-off value beyond which recanalization would seem impossible has been determined...
