Recently, we and other group have reported that furosemide administration along with hypertonic saline solution enhanced diuretic efficiency of furosemide. However, little is known about factors which associated with high diuretic efficiency by hypertonic saline solution with furosemide therapy. To identify predictors of diuretic efficiency in the hypertonic saline solution with furosemide therapy, we recruited 30 consecutive hospitalized heart failure (HF) patients with volume overload (77 ± 10 years, systolic blood pressure > 90 mmHg, and estimated glomerular filtration rate > 15 ml/min/1...

For arrhythmia treatment or sudden cardiac death prevention in hemodialysis patients, there is a frequent need for placement of a cardiac implantable electronic device (pacemaker, implantable cardioverter defibrillator, or cardiac resynchronization device). Leads from a cardiac implantable electronic device can cause central vein stenosis and carry the risk of tricuspid regurgitation or contribute to infective endocarditis. In patients with end-stage kidney disease requiring vascular access and cardiac implantable electronic device, the best strategy is to create an arteriovenous fistula on the contralateral upper limb for a cardiac implantable electronic device and avoidance of central vein catheter...

This original clinical research study id focused on description of baseline anatomy and outcomes after transcatheter aortic valve implantation (TAVI) in patients presenting with severe aortic stenosis (AS) and bicuspid aortic valve (BAV). We compared this BAV population with a population of patients with AS and tricuspid aortic valves after a propensity score matching developed by a multivariate logistic regression according to a non-parsimonious approach. Baseline anatomical characteristics were obtained by transthoracic echocardiography (TTE) and multi-sliced computed tomography (MSCT) and compared by chi-square and t-student tests...

Evaluation of antiphospholipid antibodies (aPL) and correlation with heart valve abnormalities among patients with systemic lupus erythematosus (SLE). Nested case-control study was conducted with 70 patients with SLE selected from a longitudinal database based on levels of aPL and presence or absence of valve disease by echocardiogram. Valvular abnormalities observed were regurgitation (52), other (14), artificial valves (4), stenosis (2), thickening (2) and no Libman-Sacks endocarditis (0). The mitral valve was the most commonly affected (30 abnormalities), followed by the tricuspid (20 abnormalities)...

INTRODUCTION: the incidence of invasive infections caused by pneumococcus (Streptococcus pneumoniae) has declined since generalized vaccination with pneumococcal conjugated vaccine, but it is still a prevalent pathogen in children. Amongst pneumococcal invasive infections, IE (infectious endocarditis) is rare, with an incidence between 1 and 7%. CASE REPORT: We describe the case of a previously healthy 4 year old boy, who had received one dose of 10-valent pneumococcal conjugate vaccine who presents with fever, a new heart murmur and heart failure...

Advancements in transcatheter technology has increased the number of therapeutic options for patients with tricuspid regurgitation. One category of repair devices attempts to augment leaflet coaptation by either leaflet plication or by functioning as a space occupying device. These include the MitraClip (Abbott, Santa Clara, CA, USA), PASCAL (Edwards Lifesciences, Irvine, CA, USA) and FORMA (Edwards Lifesciences, Irvine, CA, USA) devices. All three have been successfully implanted with promising short term echocardiographic and clinical outcomes...

High lethality of aortic dissection necessitates accurate predictive metrics for dissection risk assessment. The not infrequent incidence of dissection at aortic diameters <5.5 cm, the current threshold guideline for surgical intervention (Nishimura et al., 2014), indicates an unmet need for improved evidence-based risk stratification metrics. Meeting this need requires a fundamental understanding of the structural mechanisms responsible for dissection evolution within the vessel wall. We present a structural model of the repeating lamellar structure of the aortic media comprised of elastic lamellae and collagen fiber networks, the primary load-bearing components of the vessel wall...

BACKGROUND: Quantifying right ventricular function in patients with a systemic right ventricle (RV) is difficult but important for prognosis. Tissue motion annular displacement tracks displacement of the tricuspid annulus toward the apex. We evaluated this measure alongside fractional area change (FAC) on patients with single, RV prior to the bidirectional Glenn procedure. We tested both measures for correlation with outcomes. METHODS: Retrospective measurement of tissue motion annular displacement and FAC was performed on echocardiographic clips obtained prior to the bidirectional Glenn...

BACKGROUND: After the surgical correction of Tetralogy of Fallot (TOF), surgical scars and natural obstacles form pathways capable of supporting an atrial tachyarrhythmia (AT). Radiofrequency ablation is effective, although the few studies to date on this topic had relatively short follow-up periods. AIM: The aims of the study were to evaluate the acute and long-term effects of RF ablation of AT and examine the characteristics of arrhythmia recurrence. METHODS: Tetralogy of Fallot patients (N 16, age 44...

A 47-year-old woman with a medical history of Raynaud's phenomenon presented with fever, cough and shortness of breath. She was found to have left lower lobe consolidation and pleural effusion and was treated as a case of pneumonia. During the hospital course, her respiratory status worsened, and she was intubated on the third hospital day. To investigate the high A-a gradient, a Computerized Tomographic Pulmonary Embolism (CTPE) study was done which identified a large left lower pulmonary artery embolism. She was also found to have a new murmur, and an echocardiogram demonstrated a large lesion on tricuspid valve...

Although vancomycin administration is recommended for the treatment of infective endocarditis (IE) caused by methicillin-resistant Staphylococcus aureus (MRSA), it is unclear whether an alternative agent, daptomycin, can be used to treat IE with pulmonary complications. A 26-year-old female who had undergone surgical repair of a ventricular septal defect as an early teenager presented with fever, headache, and vomiting. She was admitted to our hospital and diagnosed with right-sided IE with septic pulmonary embolism caused by MRSA...

Aims: Secondary mitral regurgitation (MR) drives adverse remodelling towards late heart failure stages. Little is known about the evolution of MR under guideline-directed therapy (GDT) and its relation to cardiac remodelling and outcome. We therefore aimed to assess incidence, impact, and predictors of progressive secondary MR in patients under GDT. Methods and results: We prospectively enrolled 249 patients with chronic heart failure and reduced ejection fraction receiving GDT in this long-term observational study...
