OBJECTIVE: Echocardiography is the most important tool to assess infants with congenital diaphragmatic hernia (CDH) for pulmonary hypertension (PH). The pattern of blood flow in the pulmonary artery [described as time to peak velocity (TPV)/right ventricular ejection time (RVET) ratio] provides distinct information about pulmonary arterial pressure. The aim of our study was to investigate the correlation of TPV/RVET measurements with the most commonly used classification system for PH in CDH newborns and the association of these measurements with outcome parameters...

AIMS: Heart failure with a preserved ejection fraction (HF-PEF) remains a difficult clinical diagnosis. The aim of this study was to test the utility of established criteria to classify patients with HF-PEF. We prospectively enrolled patients into one of five groups across a spectrum of cardiac disease and applied three different criteria for HF-PEF and calculated diagnostic metrics. METHODS AND RESULTS: A total of 565 patients were included in the analysis, including 170 patients with an adjudicated diagnosis of HF-PEF, 152 patients with heart failure with reduced ejection fraction, 152 patients at risk for heart failure, and 91 age-matched healthy controls...

Debate on the proper timing of pulmonary valve replacement (PVR) after repair of tetralogy of Fallot is still continuing. We aim to clarify how the different components of right ventricle (RV) changed with relieved volume overload in the remodeling process after pulmonary valve replacement and gain a clear idea of the relationship between different right ventricle components function and exercise capacity after PVR in these patients. The medical records and results of cardiac magnetic resonance imaging and cardiopulmonary exercise testing of 25 consecutive eligible patients were reviewed...

BACKGROUND: Due to the increase of elderly and diabetes patients, surgeons encounter patients requiring treatment of critical limb ischemia (CLI) in the presence of systemic arteriosclerotic diseases. In this study, we retrospectively investigated the prevalence of coronary artery disease (CAD) in patients with CLI who underwent major (above-the-ankle) amputation or nonmajor amputation (below-the-ankle amputation or debridement of wound). METHODS: We retrospectively investigated 129 consecutive patients surgically managed for CLI in our institution between January 2013 and December 2015...

BACKGROUND: Double valve surgery is associated with an increased peri-operative morbidity and mortality. A less invasive right thoracotomy approach may be a viable alternative to median sternotomy surgery in these higher-risk patients. METHODS: We retrospectively analyzed the baseline demographics, operative characteristics, and post-operative outcomes of patients who underwent minimally invasive double valve surgery between January 2009 and December 2011 at our institution...

BACKGROUND: Combining a ring annuloplasty (Ring) with a mitral subvalvular intervention (Ring + subvalvular) in patients with secondary mitral regurgitation (MR) may improve mitral valve (MV) repair durability. However, the outcomes of this strategy compared with a Ring only, have not been clearly defined. METHODS: A systematic review and meta-analysis was performed utilizing randomized controlled and propensity matched studies which compared a Ring + subvalvular versus Ring MV repair for the treatment of secondary MR...

Introduction: Allopurinol used in the treatment of gout has been shown to improve the vascular endothelial dysfunction and reduce the dysfunction of the failing heart. This study was done to evaluate the effect and safety of allopurinol in non-hyperuricemic patients with chronic severe left ventricular (LV) dysfunction. Methods: In this study, 35 consecutive cases of non-hyperuricemic patients with chronic heart failure who had severe LV systolic dysfunction (ejection fraction of less than 35%) and were on optimal guideline directed medical therapies for at least 3 months were included...

Strain imaging is a sensitive marker of myocardial dysfunction and may be underused in Takotsubo cardiomyopathy (TC). We present a case of biventricular TC in which early improvement in left ventricular longitudinal strain predated subsequent improvement in ejection fraction. Early temporal patterns of strain of the left and right ventricles have not previously been described in TC. Our case illustrates how strain can be a sensitive marker for myocardial dysfunction and recovery in TC. Increased use of strain in TC may have further implications on prognosis and management...

We present the case of a 61-year-old woman admitted with chest pain and an ECG demonstrating ST-segment elevation in the lateral leads. Emergency coronary angiography demonstrated an occluded obtuse marginal branch. Percutaneous intervention was unsuccessful as the lesion could not be crossed with a wire. Left ventriculography and transthoracic echocardiography demonstrated hypokinesis of the entire apex but preserved contractility of the basal segments, consistent with a diagnosis of apical ballooning syndrome (ABS)...

BACKGROUND AND AIM: Epicardial fat (EF) is increased in obesity and has important interactions with atrial and ventricular myocardium. Most of the evidence in this scenario can be confused by the presence of comorbidities such as hypertension, diabetes and dyslipidemia, which are very common in this population. The influence of EF on atrial remodeling and cardiac function demands further investigation on morbidly obese without these comorbidities. METHODS AND RESULTS: We prospectively recruited 20 metabolically healthy morbidly obese and 20 normo-weights controls...

If the heart is represented by a hydraulic pump, cardiac power represents the hydraulic function of the heart. Cardiac pump function is frequently determined through left ventricular ejection fraction using imaging. This study aims to validate resting cardiac power output (CPO) as a predictive biomarker in patients with advanced heart failure (HF). One hundred and seventy-two patients with HF severe enough to warrant cardiac transplantation were retrospectively reviewed at a single tertiary care institution between September 2010 and July 2013...

This study aimed to assess the prognostic value of soluble ST2 (sST2) for risk stratification in patients undergoing transcatheter aortic valve implantation (TAVI). In 461 patients undergoing TAVI, sST2 was determined at baseline and categorized into quartiles. An optimum cutoff of 29 ng/ml was calculated. Primary end point was 1-year all-cause mortality. Results were validated in an independent cohort. Patients with sST2 >29 ng/ml had an increased 30-day (9.7% vs 4.6%, p = 0.043) and 1-year mortality (38...

Management of waste of electric and electronic equipment (WEEE) is a key issue for modern societies; furthermore, it contains valuable materials that can be recycled, especially in printed circuit boards (PCB), which have approximately one-third of their weight in copper. In this study we demonstrated the use of laser to strip the covering soldering mask on PCB's, thus exposing the copper underneath so that extraction techniques may take place. Using a Q-Switched Nd:YAG laser operating at 1064nm and 532nm we tested the procedure under different energy conditions...

Planet formation theories predict that some planets may be ejected from their parent systems as result of dynamical interactions and other processes. Unbound planets can also be formed through gravitational collapse, in a way similar to that in which stars form. A handful of free-floating planetary-mass objects have been discovered by infrared surveys of young stellar clusters and star-forming regions as well as wide-field surveys, but these studies are incomplete for objects below five Jupiter masses. Gravitational microlensing is the only method capable of exploring the entire population of free-floating planets down to Mars-mass objects, because the microlensing signal does not depend on the brightness of the lensing object...

In previous studies mechanical dispersion (MD) predicted ventricular arrhythmias independently of left ventricular ejection fraction (LVEF). Moreover the combination of MD and global longitudinal strain (GLS) increased the prediction of arrhythmic events. We investigated the prognostic value of a new 2D-strain index, GLS/MD, in patients with heart failure (HF). We analysed 340 consecutive HF outpatients in sinus rhythm. Echocardiography was performed at 1.6±0.4 months after hospital discharge. The end point included sudden cardiac death, ventricular fibrillation and sustained ventricular tachycardia (SCD/VA)...
