Acute decompensated heart failure (ADHF) is a common reason for admission to the hospital, and readmission is frequent. Multiple factors contribute to rehospitalizations, but inadequate assessment of volume status leading to persistent congestion is an important factor. We sought to determine if focused cardiac ultrasound (FCU) of the inferior vena cava (IVC), as a surrogate of volume status, would predict readmission of ADHF patients after index hospitalization. Patients admitted with a primary diagnosis of ADHF were prospectively enrolled...

Cell and gene therapy are exciting and promising strategies for the purpose of cardiac regeneration in the setting of heart failure with reduced ejection fraction (HFrEF). Before they can be considered for use, and implemented in humans, extensive preclinical studies are required in large animal models to evaluate the safety, efficacy, and fate of the injectate (e.g., stem cells) once delivered into the myocardium. Small rodent models offer advantages (e.g., cost effectiveness, amenability for genetic manipulation); however, given inherent limitations of these models, the findings in these rarely translate into the clinic...

Angiosarcomas of the uterine is a malignant and poor prognostic tumor and can either be a primary sarcoma or arising secondary to radiotherapy of a more complex tumor. Primary uterine angiosarcomas are exceptional and probably arise from embryonic vascular remnants, teratoma or from the rich uterine vasculature. We reported a rare case of primary angiosarcoma of uterine that at the time of diagnosis presented with sign and symptom of local and distant metastasis. The patient presented with dyspnea, chest pain, and history of vaginal bleeding and pelvic pain...

Wave intensity (WI) is a novel noninvasive index of circulatory dynamics that reflects ventriculo-arterial coupling. It is calculated as the product of the first derivative of blood pressure and that of flow velocity measured by carotid echocardiography. This study aimed to clarify the clinical implications of WI and its relation with carbon dioxide production (VE/VCO 2 slope). Twenty-one healthy volunteers (control group) and 21 patients with hypertension (HT group) underwent cardiopulmonary exercise testing (CPX) and exercise stress echocardiography...

AIM: Biliary lithiasis is common in most western countries. Symptomatic patients will also have choledocholithiasis in 10% of the cases. For patients with intermediate probability of CBD stones, the recommended imaging studies are endoscopic ultrasound (EUS) or MRCP. This study aims to identify early factors that can be used as predictors for the presence of CBD stones, and by that to find which patient should undergo ERCP without an early EUS. METHODS: This is a retrospective cohort study including all patients who underwent EUS for suspected choledocholithiasis at the Soroka University Medical Center (SUMC) in the years 2009-2014...

OBJECTIVES: In sacrococcygeal teratoma, the presence of high-output cardiac failure resulting from arteriovenous shunting through the large tumor has been associated with an adverse outcome. The objective of this study was to determine whether the tumor size and cardiac biomarkers in cord blood can predict neonatal survival in sacrococcygeal teratoma. METHODS: The study population consisted of 25 neonates with sacrococcygeal teratoma. Tumor size was calculated by the ellipsoid formula using dimensions measured by antenatal ultrasound ([length × width × depth in cm] × 0...

BACKGROUND: Counter-pulsation control (CPC) by ventricular assist devices (VADs) is believed to reduce cardiac load and increase coronary perfusion. However, patients with VADs have a higher risk of arrhythmia, which may cause the CPC to fail. Consequently, CPC has not been applied by VADs in clinical practice. The phase-locked loop (PLL) algorithm for CPC is readily implemented in VADs; however, it requires a normal, consistent heartbeat for adequate performance. When an arrhythmia occurs, the algorithm maintains a constant pumping rate despite the unstable heartbeat...

BACKGROUND: Although only high-flow arteriovenous fistulas (AVFs) are postulated to cause high-output cardiac failure (HOCF), there are currently no universally accepted criteria defining a high-flow fistula. METHODS: To verify if vascular access blood flow (Qa) ≥ 2000 ml/min provides an accurate definition of high-flow fistula, we selected 29 consecutive patients with Qa ≥ 2000 ml/min at color-duplex ultrasound examination and assessed them for the presence of cardiac failure symptoms; transthoracic echocardiography was also performed...

BACKGROUND: Inspiratory muscle weakness is associated with the development of exercise intolerance in patients with heart failure (HF). Ultrasound assessment of the diaphragm is used to evaluate respiratory muscle function, but its application in patients with HF remains undefined. We examined the relationship of diaphragm function as assessed by ultrasonography with inspiratory muscle strength and exercise tolerance in HF. METHODS AND RESULTS: Seventy-seven patients hospitalized with HF were enrolled...

Budd-Chiari syndrome (BCS) is defined by clinical and laboratory signs associated with partial or complete impairment of hepatic venous drainage in the absence of right heart failure or constrictive pericarditis. Primary BCS is the most frequent type and is a complication of hypercoagulable states, in particular myeloproliferative neoplasms. Secondary BCS involves tumor invasion or extrinsic compression. Most patients present with chronic BCS including a non-cirrhotic, dysmorphic, chronic liver disease with various degrees of fibrosis deposition...

Pleural effusion (PLEFF), mostly caused by volume overload, congestive heart failure, and pleuropulmonary infection, is a common condition in critical care patients. Thoracic ultrasound (TUS) helps clinicians not only to visualize pleural effusion, but also to distinguish between the different types. Furthermore, TUS is essential during thoracentesis and chest tube drainage as it increases safety and decreases life-threatening complications. It is crucial not only during needle or tube drainage insertion, but also to monitor the volume of the drained PLEFF...

The jugular venous pulse (JVP) is one of the main parameters of cardiac function and is used by cardiologists in diagnosing heart failure. Its waveform comprises three positive waves (a, c and v) and two negative waves (x and y). Recently, it was found that JVP can be extrapolated from an ultrasound (US) video recording of the internal jugular vein (IJV), suggesting its application in space missions, on which US scanners are already widely used. To date, the feasibility of assessing JVP in microgravity (microG) has not been investigated...

Adequate assessment of fluid status is an imperative objective in the management of all types of patients in cardiology, intensive care, and especially nephrology. Fluid overload is one of the most common modifiable risk factors directly associated with hypertension, heart failure, left ventricular hypertrophy, and eventually, higher morbidity and mortality risk in these categories of patients. Different methods are commonly used to determine fluid status (eg, clinical assessment, natriuretic peptide concentrations, echocardiography, inferior vena cava measurements, or bioimpedance analysis)...
