BACKGROUND AND OBJECTIVES: The most common injury to the heart valve with rheumatic involvement is mitral stenosis, which is the reason for a big number of cardiac operations in Brazil. Commissurotomy is the traditional technique that is still widely used for this condition, although late postoperative restenosis is concerning. This study's purpose was to compare the histological findings of porcine cusp mitral valves treated in vitro with commissurotomy with a scalpel blade to those treated with high-power laser (HPL) cutting, using appropriate staining techniques...

Although preliminary data suggests that ibrutinib may increase risk of atrial fibrillation (AF), the incidence of AF in a general cohort of chronic lymphocytic leukemia (CLL) patients is unknown. We evaluated the prevalence of AF at CLL diagnosis and incidence of AF during follow-up in 2444 patients with newly diagnosed CLL. A prior history of AF was present at CLL diagnosis in 148 (6.1%). Among the 2292 patients without history of AF, 139 (6.1%) developed incident AF during follow-up (incidence approximately 1%/year)...

CONTEXT AND AIMS: The advent of systematic screening for rheumatic heart disease (RHD) by echocardiography in endemic regions has led to a new entity: borderline RHD. The pathogenicity and natural history of borderline RHD needs to be addressed. The aim of this study was to assess the outcomes of children detected by echocardiography as having borderline RHD. METHODS: Schoolchildren in 4th grade (i.e., aged 9-10years) who were prospectively echo-screened for RHD (2012-2014) in Nouméa, New Caledonia, were asked to participate...

BACKGROUND: There are limited data regarding the influence of liver dysfunction on outcomes of transcatheter aortic valve implantation (TAVI). Model for End-stage Liver Disease eXcluding International normalized ratio (MELD-XI) score, which was originally developed for patients with cirrhosis awaiting liver transplantation, has been reported as a predictor of heart disease. The aim of this study was to investigate the prognostic value of MELD-XI score for patients undergoing TAVI. METHODS: Data from the prospectively maintained Optimized transCathEter vAlvular iNtervention (OCEAN-TAVI) multicenter registry were collected in 749 patients who underwent TAVI between October 2013 and August 2015...

BACKGROUND: -Although HF disproportionately affects older adults, little data exist regarding the prevalence of American College of Cardiology/American Heart Association heart failure (HF) stages among older individuals in the community. Additionally, the role of contemporary measures of longitudinal strain (LS) and diastolic dysfunction in defining HF stages is unclear. METHODS: -HF stages were classified in 6,118 participants in the Atherosclerosis Risk in Communities study (age 67 - 91 years) at the fifth study visit as follows: stage A (asymptomatic with HF risk factors but no cardiac structural or functional abnormalities), B (asymptomatic with structural abnormalities, defined as left ventricular hypertrophy, dilation or dysfunction, or significant valvular disease), C1 (clinical HF without prior hospitalization), and C2 (clinical HF with prior hospitalization)...

AIMS: Impaired left ventricular (LV) deformation despite preserved LV ejection fraction (LVEF) is common and predicts outcomes in heart failure with preserved LVEF. We hypothesized that impaired LV deformation at rest is a marker of impaired cardiac systolic and diastolic reserve, and aimed to determine whether resting longitudinal (LS) and circumferential strain (CS) are associated with invasively measured haemodynamic response to exercise in patients with dyspnoea and a normal LVEF...

BACKGROUND: Once aortic stenosis (AS) is severe, patients develop symptoms at different stages. Indeed, symptom status may correlate poorly with the grade of valve narrowing. Multiple pathophysiological mechanisms, other than valvular load, may explain the link between AS and symptom severity. We aimed to describe the relationship between the severity of symptoms and the characteristics of a cohort of patients with severe AS already referred for aortic valve replacement (AVR). METHODS: We analyzed 118 consecutive patients (70±9 years, 55% men) with severe AS referred for AVR...

BACKGROUND: Globally, heart failure (HF) has been recognized as one of the major cardiovascular disorder with high morbidity, mortality and considerable social impact. In Sub Saharan African countries, HF has turned out as a leading form of cardiovascular diseases, and has considerable socioeconomic impact. However, there are differences in clinical characteristics and survival status among patients with preserved (HFpEF) and reduced (HFrEF) ejection fraction. The aim of this study is to outline the clinical characteristics and medication profile, assess the survival status and prognostic factors of Ethiopian HF patients with HFrEF and HFpEF...

Aortic stenosis is one the most frequent valvular diseases in developed countries, and its impact on public healthcare resources and assistance is increasing. A substantial proportion of elderly patients with severe aortic stenosis is frequently not eligible for surgery because of advanced age, frailty and multiple comorbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy...

BACKGROUND: As the intracardiac flow field is affected by changes in shape and motility of the heart, intraventricular flow features can provide diagnostic indications. Ventricular flow patterns differ depending on the cardiac condition and the exploration of different clinical cases can provide insights into how flow fields alter in different pathologies. METHODS: In this study, we applied a patient-specific computational fluid dynamics model of the left ventricle and mitral valve, with prescribed moving boundaries based on transesophageal ultrasound images for three cardiac pathologies, to verify the abnormal flow patterns in impaired hearts...

In adults on chronic hemodialysis, achieving a hemoglobin concentration of 12g/dl and above with erythropoiesis stimulating agents leads to increased cardiovascular events and mortality, but this may not be true in children. Therefore, we conducted a retrospective cohort study of pediatric patients (under 18) from the Centers for Medicare and Medicaid Services End Stage Renal Disease (ESRD) Clinical Performance Measures (CPM) project (2000 to 2008) merged with the United States Renal Data System. Hemoglobin was determined from the Clinical Performance Measures data, and beginning annually on January 1st of the next year, patients were followed for up to 1 year...
