BACKGROUND: Proper integration of multiple imaging modalities in the routine follow-up of patients with repaired tetralogy of Fallout (TOF) is poorly supported by data. We report our single center comparative study between cardiac magnetic resonance (CMR) and echocardiography to assess equipoise in the clinical utility of these two imaging methods in an unselected consecutive cohort of TOF patients referred to our outpatient clinic. MATERIAL AND METHODS: In this cross-sectional study, repaired TOF patients who underwent CMR and echocardiography within a 4-week period between 2010 and 2011 at our Center were included...

BACKGROUND: Myocardial dysfunction has been implicated in gradual heart failure in transposition of the great arteries (TGA) with a systemic right ventricle (RV). Fibrosis can be assessed using the extracellular volume fraction (ECV). Our aim was to measure ECV and determine its associations with clinical findings and outcomes. METHODS: We prospectively measured ECV in systemic RV subjects (either D-loop after atrial switch or L-loop) and healthy controls. T1 measurements for a single mid-ventricular short-axis plane before and 3, 7, and 15 min after gadolinium contrast were used to quantify systemic ventricular ECV...

PURPOSE: Adaptive servo-ventilation (ASV) is a ventilator algorithm able to correct breathing through anticyclic support of breathing in patients with central sleep apnea (CSA). So far, very few data exist regarding the role of ASV on acute heart failure with preserved ejection fraction (HFpEF). METHODS: We performed a single-center prospective, randomized, case-control study in consecutive acute HFpEF (left ventricle ejection fraction, LVEF ≥ 45%) patients with sleep-disordered breathing (SDB, apnea-hypopnea index, AHI > 15/h) and prevalence of CSA...

The aim of the present study was to investigate the predictive value of the plasma matrix metalloproteinase-9 (MMP-9) level at admission for in-hospital mortality in patients who received emergency percutaneous coronary intervention (PCI) following AMI. A single blood sample was collected at admission from 155 consecutive AMI patients who underwent emergent PCI. The plasma levels of MMP-9 value (528.9±191.6 ng/ml) were significantly higher in the patients who died (n=24) than in the survivors (385.4±236.0 ng/ml) during 14 days of hospitalization ( P =0...

BACKGROUND: Right ventricular function and biomarkers of B-type natriuretic peptide (BNP) and N-Terminal pro-BNP (NT pro-BNP) are used to determine the severity of right ventricular failure and outcomes from pulmonary hypertension. Real-time three-dimensional echocardiography (3DE) is a novel quantitative measure of the right ventricle and decreases the geometric assumptions from conventional two-dimensional echocardiography (2DE). We correlated right ventricular functional measures using 2DE and single-beat 3DE with biomarkers and hemodynamics to determine the severity of pediatric pulmonary hypertension...

Although there are many biomarkers for heart failure, limited data are available regarding their prognostic value in adult congenital heart disease (ACHD). We investigated the potential of various biomarkers to predict ACHD mortality in a single-center, retrospective cohort study. Blood levels of neurohormones [angiotensin II, endothelin-1 (ET-1), norepinephrine (NE), aldosterone, and plasma renin activity]; inflammatory biomarkers [high-sensitivity C-reactive protein (hs-CRP), high-sensitivity tumor necrosis factor, soluble TNF receptor type I and II (sTNF-RI and sTNF-RII), and interleukin-6 (IL-6)]; and brain natriuretic peptide (BNP) were measured in 103 ACHD patients (median age 28 years)...

BACKGROUND/AIMS: Plasma concentrations of the N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) are increased in end-stage renal disease. Improvement in hemodynamic stability has been reported when switching from hemodialysis (HD) to on-line hemodiafiltration (ol-HDF). The aim of this study was to investigate plasma concentrations of NT-proBNP, BNP and neuropeptide Y (NPY) during a 1-year follow-up, after a change from high-flux HD to postdilution ol-HDF. Additional variables were also studied, e...

BACKGROUND: Adults with single ventricle physiology palliated with a Fontan circulation experience high mortality due to circulatory failure. Renin-angiotensin-aldosterone system (RAAS) genotype contributes to adverse cardiovascular outcomes in acquired heart failure. This study evaluated associations between RAAS genotype, ventricular mass and function in a contemporary cohort of adults with a Fontan circulation. METHODS: This single-center prospective study included adults (n=106) seen after the Fontan operation (mean age 27±9years)...

BACKGROUND: Pulmonary artery hypertension (PAH) is characterized by vascular remodeling, high pulmonary blood pressure, and right ventricular hypertrophy. Oxidative stress, inflammation and pulmonary artery remodeling are important components in PAH. Ellagic acid (EA) is a phenolic compound with anti-oxidative, anti-inflammatory, and anti-proliferative properties. This study aimed to investigate whether EA could prevent the development of monocrotaline (MCT)-induced PAH in rats. METHODS: Male Sprague-Dawley rats received EA (30 and 50mg/kg/day) or vehicle one day after a single-dose of monocrotaline (MCT, 60mg/kg)...

Data regarding the value of B-type natriuretic peptide (BNP) measurements in infants with a single-ventricle (SV) physiology are lacking. This analysis aimed to describe the BNP level changes in infants with an SV physiology before and after superior cavopulmonary connection (SCPC) surgery. Levels of BNP were measured by a core laboratory before SCPC (at 5.0 ± 1.6 months) and at the age of 14 months during a multicenter trial of angiotensin-converting enzyme inhibition therapy for infants with SV. Multivariable longitudinal analysis was used to model the associations between BNP levels and three sets of grouped variables (echocardiography, catheterization, growth)...

INTRODUCTION: Right ventricular pacing (RVP) causes ventricular desynchronization and may lead to the development of heart failure (HF). Prolongation of atrioventricular delay (AVD) in DDDR pacemakers reduces unnecessary RV stimulation. The aim of the study was to verify the influence of RVP reduction on HF symptoms. METHODS: The study comprised 31 patients (17 men, mean age: 71.6 ± 8 yrs) with DDDR pacemaker implanted due to sinus node dysfunction (SND). At baseline, 28 patients did not present any symptoms of HF...

The field of cardio-oncology is challenged to address an ever greater spectrum of cardiotoxicity associated with combination chemotherapy, greater dose intensity, extremes of age, and enhanced patient survival which exposes more protracted risk of developing congestive heart failure (CHF). Recent reports of chemotherapy-induced hypertension as a common adverse effect of angiogenesis inhibitors and immunosuppressants clarify the need for routine blood pressure (BP) monitoring and guideline-based management of hypertension as an integral strategy to preserve LV function...

BACKGROUND: Among adults with congenital heart diseases (CHD) evaluation of sudden cardiac death (SCD) risk remains a great challenge. Although microvolt T-wave alternans has been incorporated into SCD risk stratification algorithm, its role in adults with CHD still requires investigation. We sought to determine the incidence of MTWA in this specific group and its coincidence with ventricular arrhythmia (VA) and other clinical findings presumably associated with SCD. METHODS: A case-control study was performed in which 102 patients with CHD characterized by right ventricle pathology or single ventricle physiology (TGA, UVH, Ebstein's anomaly, ccTGA, Eisenmenger syndrome, DORV, CAT, unoperated ToF) were compared to 45 age- and sex-matched controls...
