Cardiac resynchronization therapy (CRT) is an established therapy for symptomatic heart failure (HF). Unfortunately, many recipients remain nonresponders. Studies have revealed the potential role of multipoint pacing (MPP) in improving response and outcomes. The aim of this study is to compare the effects of MPP against those of standard biventricular pacing (BVP) on (i) ventriculoarterial coupling (VAC) and energy efficiency of the failing heart, (ii) diastolic function, (iii) quality of life, and (iv) NT-proBNP levels and glomerular filtration rate (GFR) during a follow-up of 13 months...

OBJECTIVES: Lung ultrasound detection of B-lines has become a simple, semiquantitative, noninvasive tool for evaluating pulmonary congestion in heart failure (HF) patients. This study compared the correlation of B-lines with E/e', NT-proBNP, and ejection fraction (EF) in acute decompensated heart failure (ADHF). METHODS: Eighty-two consecutive patients who were diagnosed with acute decompensated HF were divided into two groups: preserved ejection fraction heart failure (HFpEF, EF≥50%, n=32) and reduced ejection fraction heart failure (HFrEF, EF<50%, n=50)...

BACKGROUND: Occult hepatitis B infection consists of persistence of HBV genomes in hepatocytes,absence of serum HBsAg, low/undetectable serum HBVDNA. Reactivation of HBV infection may occur during immunosuppression, but few data are available in heart transplant. OBJECTIVES: We followed-up heart recipients with or without markers of previous HBV infection,evaluating prevalence of HBV markers, incidence of HBV reactivation and its virological and clinical features...

AIMS: There is little evidence-based therapy existing for acute heart failure (AHF), hospitalizations are lengthy and expensive, and optimal monitoring of AHF patients during in-hospital treatment is poorly defined. We evaluated a rapid cardiothoracic ultrasound (CaTUS) protocol, combining focused echocardiographic evaluation of cardiac filling pressures, that is, medial E/e' and inferior vena cava index, with lung ultrasound (LUS) for guiding treatment in hospitalized AHF patients. METHODS AND RESULTS: We enrolled 20 consecutive patients hospitalized for AHF, whose in-hospital treatment was guided using the CaTUS protocol according to a pre-specified treatment protocol targeting resolution of pulmonary congestion on LUS and lowering cardiac filling pressures...

BACKGROUND: Diuretics are essential for treating acute decompensated heart failure (ADHF), but the response is inconsistent. This study aimed to clarify whether kidney volume as assessed by ultrasound (US) predicts diuretic resistance in patients with ADHF. METHODS: We enrolled 29 patients with ADHF and 32 controls. Height-adjusted kidney volume was assessed by US. We divided patients into two groups based on the median value of total daily use of furosemide (intravenous dose plus 0...

Transplant coronary artery vasculopathy (TCAV) following orthotopic heart transplantation (OHT) continues to be the primary reason for late graft failure in children. The current gold standard of diagnosis of TCAV is coronary angiography with or without intravascular ultrasound. This study investigates the longitudinal use of speckle-tracking echocardiographic strain imaging as an early non-invasive marker to screen for development of TCAV. Echocardiograms from patients who underwent OHT between 2006 and 2010 at Children's Hospital Colorado (n = 50) were retrospectively assessed...

Left ventricular remodelling (LVr) occurs post myocardial infarction (MI), predisposing people to heart failure (HF). LV mechanics and morphology are important in this process. We hence sort to characterize LV mechanics and geometry in a post-MI rodent model. Thirty-two male Sprague-Dawley rats (150-200 g) sustained MI (n = 24) or sham (Sham; n = 8) surgery. In another six sham rats invasive blood pressure measurements were performed. Ultrasound imaging was done at baseline, and 1, 3, 7, 14, 30 and 60 days following surgery, and LV mechanics and morphology assessed...

The risk of cardiac or lung failure after liver transplantation (LT) is significant. In rare cases, the usual intensive care techniques fail to maintain organ oxygenation with a risk of multiorgan dysfunction. Although extracorporeal membrane oxygenation (ECMO) is a difficult and risky procedure, it can be proposed as life-saving. Four children with either acute pulmonary (three) or cardiac (one) failure after LT, and the criteria that decided the use of ECMO (level of ventilation and results, dosage of inotropic drugs, cardiac ultrasound, blood lactate) were retrospectively reported...

As dysfunction of the vascular system is an early, modifiable step in the progression of many cardiovascular diseases, there is demand for methods to non-invasively monitor the health of the vascular system in clinical and research settings. Validated by very good agreement with more technical assessments of vascular function, like intra-arterial drug infusions and flow mediated dilation (FMD), the passive leg movement (PLM) technique has emerged as a powerful, yet relatively simple, test of peripheral vascular function...

BACKGROUND: The European Association of Cardiology (ESC) Guidelines on the diagnosis and treatment of acute heart failure (AHF) indicate prompt therapy initiation and performance of relevant investigations as paramount. Specifically, echocardiography prior to treatment is advocated only with hemodynamic instability, and the evaluation of clinical signs of peripheral perfusion and congestion is suggested as guidance for early interventions. Given the growing body of evidence on the diagnostic/monitoring capabilities of bedside ultrasound (including focused cardiac ultrasound, comprehensive echocardiography, lung ultrasound), we discuss the potential benefit of an integrated clinical/ultrasound approach at the very early stages of acute heart failure...

Dear Editor, An 83-year-old woman developed yellow-brownish infiltrates, nodules, and tumors mimicking xanthomas, mostly involving the periorbital and chest area within three months (Figure 1). She had no abnormalities in serum cholesterol or triglycerides levels. A detailed laboratory analysis revealed the presence of mild monoclonal gammopathy with a presence of immunoglobulin G (IgG) kappa light chains; however, according to hematologist consultation, it did not require medical intervention. Imaging assessment and ultrasound examination did not show any specific involvement of internal organs...

Various lung ultrasound (LUS) scanning modalities have been proposed for the detection of B-lines, also referred to as ultrasound lung comets, which are an important indication of extravascular lung water at rest and after exercise stress echo (ESE). The aim of our study was to assess the lung water spatial distribution (comet map) at rest and after ESE. We performed LUS at rest and immediately after semi-supine ESE in 135 patients (45 women, 90 men; age 62 ± 12 y, resting left ventricular ejection fraction = 41 ± 13%) with known or suspected heart failure or coronary artery disease...

Infective endocarditis complicating a quadricuspid aortic valve (QAV) is rare. Previous reports highlight the increased risk for complications, including progressive aortic regurgitation, decompensated heart failure, and valve perforation. Thus, cardiologists must be able to quickly identify QAVs to guide rapid evaluation and treatment. We report a case of infective endocarditis in a QAV identified on echocardiography and effectively managed with medical therapy alone without complications over an 8-year follow-up period...

Extracorporeal cardiac shock wave therapy (CSWT) has been used to treat patients with severe coronary heart disease and cardiac failure with good results; however, the safety of this treatment is still controversial. Its safety in clinical setting and on microstructures has been confirmed, but the influence of shock wave on the ultrastructures of myocardial cells is not clear. In this study, 12 Sprague-Dawley rats were randomly divided into control (NC) and CSWT therapy (NC+SW) groups. The heart rate, blood pressure, serum troponin I (TNI), and cardiac ultrasound were evaluated, and the myocardial inflammatory responses and fibrosis changes were compared...

BACKGROUND: Ultrasound imaging of adults with heart failure and increased central venous pressure (CVP) has shown significant thoracic duct (TD) dilation from impedance in lymphatic drainage. Elevated CVP and abnormal lymphatic drainage are implicated in severe Fontan complications, including protein losing enteropathy (PLE) and plastic bronchitis (PB). Systematic studies of TD and lymphatic circulation in children are limited, and their cervical TD normative values have not been established...

Located under the cerebral hemispheres and draining the anterior and central regions of the brain into the sinus of the posterior cerebral fossa, the vein of Galen aneurysmal malformation is considered to be a rare cause of hydrocephaly. The presence of this condition in the neonatal period typically includes intractable heart failure and a poor prognosis. We report a case of aneurysm of the vein of Galen diagnosed prenatally at 28 weeks of gestation, with the delivery at term by caesarean section of a female infant...

We present the case of a young pregnant woman with cardiopulmonary arrest due to acute coronary syndrome. Emergent coronary angiography (CAG) and intravascular ultrasound (IVUS) showed extensive coronary artery dissection in the left anterior descending artery, which was treated with primary percutaneous coronary intervention. After managing the heart failure and disseminated intravascular coagulation, a dead fetus was delivered via caesarean section 4 days after admission to the hospital. Follow-up CAG and IVUS at 18 months showed persistent dissection in the non-stented site; hence, another stent was implanted...
