INTRODUCTION: The latest recommendations for echocardiographic chamber quantification have implemented updated normal values for all cardiac chambers. PURPOSE: To evaluate the incidence of normal and abnormal values of routine echocardiographic parameters such as left ventricular ejection fraction (LVEF) and left atrial volume indexed to body surface area (LAVi) in patients with non-valvular atrial fibrillation (AF) and to determine the influence of LVEF and LAVi reclassification on the prediction of LAAT by transthoracic echocardiography...

Here, we present the case of a patient with the findings of an early intracardiac thrombus and a pulmonary embolus after major trauma. A large clot was identified extending from the inferior vena cava into the right atrium and ventricle in the setting of preserved right ventricular function. Post-traumatic intracardiac thrombus is extremely rare and no comparable cases have previously been described in the absence of a congenital heart defect and obvious myocardial injury. Best practice afterpost-traumatic intracardiac thrombus is not well established but we found that early inferior vena cava filter placement and treatment with therapeutic coagulation resulted in clinical improvement, resolution of the thrombus and no further emboli...

Holt-Oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. Skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. They range from clinodactyly, absent or digitalised thumb, hypoplastic or absent radii, and first metacarpal to hypoplastic ulna and carpal bone anomalies. Cardiac involvement ranges from asymptomatic conduction disturbances to multiple structural defects...

Dilated cardiomyopathy (DCM) may be associated with formation of intracardiac thrombi which may embolize and result in life-threatening complications. We present a 19-month-old female child with DCM who presented with a right hemispheric cerebrovascular accident. Urgent echocardiography revealed poor left ventricular systolic function and a thrombus attached to the interventricular septum along the left ventricular outflow tract. There was resolution of the thrombus following the use of warfarin.

BACKGROUND: Device indications have changed for placement of continuous-flow left ventricular assist devices (CF-LVADs). We performed a multicenter analysis evaluating temporal variations in outcomes after CF-LVAD implantation. METHODS & RESULTS: We retrospectively defined three time intervals to reflect changes in CF-LVAD technology (Period 1: 2004 to 2009; Period 2: 2010 to 2012; and Period 3: 2012 to 2014). A total of 1,064 patients (HeartMate II (HMII)=835, HeartWare (HVAD)=229) underwent CF-LVAD implantation between May 2004 and October 2014...

Right ventricular failure is a common complication associated with rotary left ventricular assist device (LVAD) support. Currently, there is no clinically approved long-term rotary right ventricular assist device (RVAD). Instead, clinicians have implanted a second rotary LVAD as RVAD in biventricular support. To prevent pulmonary hypertension, the RVAD must be operated by either reducing pump speed or banding the outflow graft. These modes differ in hydraulic performance, which may affect the pulmonary valve opening (PVO) and subsequently cause fusion, valvular insufficiency, and thrombus formation...

BACKGROUND: The literature examining clinical outcomes and readmissions during extended (> 1 yr) left ventricular assist device (LVAD) support is scarce, particularly in the era of continuous-flow LVADs. METHODS: We completed a retrospective cohort study on consecutive LVAD patients from June 2006 to March 2015, focusing on those who received more than 1 year of total LVAD support time. Demographic characteristics, clinical outcomes and readmissions were analyzed using standard statistical methods...

BACKGROUND: Recently, the role of free fatty acids (FFAs) in thromboembolism has re-emerged in the context of cardioembolic stroke. Therefore, we attempted to determine the role of FFAs in embolic risk in various potential sources of cardioembolism (PSCE). We hypothesized that if elevated FFA levels in stroke patients are associated with thrombogenesis, then patients with a well-known high risk of embolic sources would have high FFA levels. METHODS: Data collected from 2 hospital-based stroke registries were analyzed to investigate the association between FFA and PSCE...

This is a 61-year-old man with end-stage liver disease who experienced cardiac arrest secondary to a massive pulmonary embolus and intracardiac thrombus during cannulation for veno-venous extracorporeal membrane oxygenation (ECMO) in preparation for orthotopic liver transplantation (OLT). Surgery was aborted and the patient was taken back to the intensive care unit in cardiogenic shock on multiple vasopressors. The patient was unresponsive to heparin bolus and too high risk for systemic thrombolytics or embolectomy...

BACKGROUND: The contemporary role of prophylactic anticoagulation following extensive anterior wall ST-segment myocardial infarction (STEMI) is unclear. METHODS AND RESULTS: We evaluated anterior STEMI patients with left ventricle dysfunction (left ventricular ejection fraction ≤40%) ("high risk"), categorized by prophylactic warfarin use, within a regional STEMI. Patients with pre-existing atrial fibrillation were excluded. The primary outcome was an adjusted (for Global Registry of Acute Coronary Events risk score) 1-year composite of recurrent ischemia, stroke/transient ischemic attack/systemic embolism, or all-cause death...

BACKGROUND: Takotsubo cardiomyopathy is characterized by transient systolic dysfunction of the apical and mid segments of the left ventricle in the absence of obstructive coronary artery disease. Intraventricular thrombus formation is a rare complication of Takotsubo cardiomyopathy and current data almost exclusively consists of isolated case reports and a few case series. Here we describe a case of Takotsubo cardiomyopathy with formation of an apical thrombus within 24 h of symptom onset, which has been reported in the literature only once previously, to the best of our knowledge...

Left ventricular (LV) diverticulum represents a rare and frequently asymptomatic congenital anomaly, which is incidentally discovered during routine transthoracic echocardiography. We present a case of a 66-year-old female patient who was admitted to the cardiology department due to incidental finding of a tumor-like mass associated with the posterior mitral leaflet. Preliminary echocardiographic evaluation revealed a solid structure, suspected of mitral annulus calcification or LV malignancy. However, cardiac contrast-enhanced computed tomography confirmed the presence of LV diverticulum, partially filled with calcified thrombus...

Although most patients with takotsubo cardiomyopathy have a favorable outcome, complications are not uncommon. Recent studies have reported an increase in incidence of cardioembolic complications; however, the association between takotsubo cardiomyopathy and stroke, in particular thromboembolic cerebral infarction, remains unclear. We reported a 44-year-old woman who had a cerebral infarction resulting from takotsubo cardiomyopathy. She had felt chest discomfort a few days prior to infarction, and later developed left hemiparesis...

We report here a case of left atrium inversion after implanting HeartMate III LVAD, which is known to be the first in literature. LVAD can be functional only if there is adequate inflow to the device. Parameters and filling of left ventricle can be assessed by TEE. In our case, initial examination with TEE showed thrombus like images. HeartMate III has a reliable algorithm that automatically reduces pump speed if 'suction effect' is detected. HeartMate III demonstrates clean flow properties and good surface wash...

INTRODUCTION: The need for transesophageal echocardiography (TEE) before catheter ablation of atrial fibrillation (CA-AF) is still being questioned. The aim of this study is to analyze patients' (pts) risk factors of left atrial appendage thrombus (LAAT) prior to CA-AF in daily clinical practice, according to oral anticoagulation (OAC) strategies recommended by current guidelines. METHODS AND RESULTS: All pts scheduled for CA-AF from 01/2015-12/2016 in our center were included and either treated with NOACs (novel-OAC; paused 24-hours pre-ablation) or continuous vitamin K-antagonists (INR 2...

Behçet's disease (BD) is systemic vasculitis of unknown etiology, which is more common in the countries located along the Great Silk Road. The disease is diagnosed if a patient has 4 key diagnostic signs: aphthous stomatitis, genital sores, and eye and skin lesions. Vascular diseases referred to as minor criteria for BD are characterized by the formation of aneurysms and thrombosis, predominantly in the venous bed. In venous disorders, a blood clot can form in any vessel, including caval, cerebral, pulmonary, and other veins...

Device thrombosis is a devastating complication of left ventricular assist devices. The definitive treatment has been device exchange or explant. Evidence of increasing morbidity and mortality with device exchange has shifted strategies toward conservative management. In this report, we detail the use of thrombolytics as salvage therapy in a patient with an occlusive HeartWare ventricular assist device (HeartWare Inc., Framingham, MA) thrombus, resulting in long-term survival without further intervention.

BACKGROUND: The diagnosis of thrombus in the left atrium in patients with persistent atrial fibrillation (AF) and may be inconsistent because of variability in thrombus morphology. In some cases it is challenging and requires unusual approach. New Doppler-derived methods might be helpful to identify such thrombi. We evaluated quantitative differences in mechanical function of the left atrial appendage (LAA) basal segments using tissue Doppler imaging (TDI)and speckle tracking echocardiography (STE) in patients with non-valvular AF with and without LAA thrombus and compared them with SR patients...
