INTRODUCTION: Early detection of left ventricular systolic dysfunction (LVSD) is important for therapeutic strategies for Duchenne muscular dystrophy (DMD) patients. We analyzed the myocardial strain by echocardiography for the early detection of LVSD and determined the predictors of early LVSD. METHODS: Cross-sectional study of forty DMD patients with normal left ventricular ejection fraction. Global longitudinal strain (GLS) was used to analyse subtle disturbances in the longitudinal contraction of the myocardium...

PURPOSE: Multisite cardiac resynchronization therapy (MSCRT) with dual-vein left ventricular (LV) pacing has theoretical advantages over conventional CRT in faster and more physiological LV activation. We aimed to define indications, feasibility, safety, acute, and long-term results of MSCRT. METHODS: All patients implanted with MSCRT during 2008-2014 in a single center were reviewed and analyzed. RESULTS: Thirty-nine patients (90% CRT-defibrillators, 64 ± 9 years, 85% male, 74% ischemic etiology) were included...

Right ventricular (RV) geometry is altered by septal shift after pulmonary artery banding. This may reduce tricuspid regurgitation (TR) and improve ventricular function in patients with corrected transposition of great arteries and systemic right ventricle. However, banding is risky in sick patients with severe RV failure. There are no predictive models in clinical practice to test this septal shift hypothesis before a risky surgery. A transcatheter model to mimic a pulmonary artery band is presented in corrected transposition of great arteries with failing right ventricle and severe TR...

Echocardiography has contributed to the care of critically ill patients but there remains a need for more publications about its association with outcomes to confirm its role. We conducted a retrospective review of trauma and burn patients that were admitted to our intensive care unit between 2015 and 2017 that underwent hemodynamic transesophageal echocardiography. Data collected included demographics, clinical and laboratory data. Right ventricle fractional area of change (RVFAC) measurements were performed on still mages obtained from mid-esophageal four-chamber-view clips...

Transcatheter pulmonary valve replacement is now a feasible alternative to surgical pulmonary valve replacement in children and adults with dysfunctional right ventricular outflow conduits. Currently, 2 types of valves can be used for this application. This article provides an overview of the procedure and how it is performed, indications and contraindications for transcatheter pulmonary valve replacement, and short- and long-term outcomes. Nursing considerations mainly focus on educating patients, preventing bleeding and infection, monitoring renal function, and preventing injury to the catheter insertion site...

PURPOSE OF REVIEW: We review the trials that have demonstrated potentially harmful effects from right ventricular (RV) apical pacing as well as reviewing the evidence of alternative RV pacing sites and cardiac resynchronization therapy (CRT) for patients who have heart failure and atrioventricular (AV) block. RECENT FINDINGS: The role of CRT in patients with AV block and impaired left ventricular function remains an important consideration. The BLOCK HF trial demonstrated better outcomes with CRT pacing over RV pacing in patients with left ventricular systolic dysfunction (LVSD) and AV block who were expected to have a high RV pacing burden, but failed to demonstrate a mortality benefit...

BACKGROUND: The right ventricular ejection fraction (RVEF) is a surrogate marker of right ventricular function in pulmonary hypertension (PH), but its measurement is complicated and time consuming. The tricuspid annular plane systolic excursion (TAPSE) measures only the longitudinal component of RV contraction while the right ventricular fractional area change (RVFAC) takes into account both the longitudinal and the transversal components. The aim of our study was to evaluate the relationship between RVEF, RVFAC, and TAPSE according to hemodynamic severity in two groups of patients with PH: pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH)...

The clinical value of cardiac color ultrasound and cardiac troponin T (cTnT) combined with dynamic electrocardiogram in evaluating the treatment effect on acute pulmonary embolism (APE) was investigated. Ninety-eight patients with APE treated in Jinan Zhangqiu District Hospital of TCM from March 2016 to February 2017 were selected, and they were examined via the cardiac color ultrasound, cTnT and dynamic electrocardiogram to evaluate the clinical value in the treatment of pulmonary embolism. Electrocardiogram showed that there was no significant difference in the poor prognosis rate between right ventricular strain group and non-right ventricular strain group (P>0...

A novel sternotomy sparing implantation technique for the Thoratec HeartMate 3 is described. Cannulation of the left ventricular apex is performed via a minithoracotomy in the left fourth or fifth intercostal space. The outflow graft is advanced through the pericardium to a second minithoracotomy in the right second intercostal space and then anastomosed to the ascending aorta. This approach was performed in three patients so far with no need for conversion. We did not observe any perioperative adverse events, such as bleeding or thromboembolic complications, as well as no short-term mortality...

Acute respiratory distress syndrome (ARDS) is the most severe form of acute respiratory failure characterized by diffuse alveolar and endothelial damage. The severe pathophysiological changes in lung parenchyma and pulmonary circulation together with the effects of positive pressure ventilation profoundly affect heart lung interactions in ARDS. The term pulmonary vascular dysfunction (PVD) refers to the specific involvement of the vascular compartment in ARDS and is expressed clinically by an increase in pulmonary arterial (PA) pressure and pulmonary vascular resistance both affecting right ventricular (RV) afterload...

OBJECTIVE: Quantifying unbalance, the threshold for single ventricle palliation vs biventricular repair in patients with unbalanced complete atrioventricular septal defect (AVSD), is challenging. Utilizing a core lab review of baseline echocardiograms, we sought to assess the correlations among commonly used measures of unbalance and common atrioventricular valve (AVV) and ventricular sizes. METHODS: A single reviewer evaluated baseline echocardiograms from an inception cohort of babies < age 1 year with complete AVSD admitted to one of 25 CHSS institutions...

Long-term right ventricular pacing is associated with electrical and mechanical dyssynchrony and ultimately development of pacing-induced cardiomyopathy (PICM) in a subset of patients. Patients with a high degree of pacing burden and reduced left ventricular (LV) function prior to pacemaker implantation are at the greatest risk for developing PICM. Cardiac resynchronization therapy (CRT) has an established role in the treatment of patients with LV systolic heart failure and intraventricular delay and has been used to successfully treat PICM...

BACKGROUND: The accurate measurement of cardiac output (CO) is required in patients with pulmonary hypertension (PH).While both the thermodilution (TDCO) and indirect Fick (IFCO) methods are commonly used, there is little data comparing them in patients with PH. METHODS: We performed a retrospective analysis of patients evaluated at our center. All patients who had right heart catheterization (RHC) within 3 months of an echocardiogram, and CO assessment by both TDCO and IFCO methods were included...

BACKGROUND: The role of right atrial (RA) dysfunction in patients with pulmonary hypertension (PH), as evaluated by two-dimensional speckle-tracking echocardiography (2D-STE) remains to be determined. METHODS: Sixty consecutive PH patients and 30 healthy volunteers were included. RA function was evaluated by 2D-STE, and the following parameters were recorded: an average longitudinal strain (LS) curve that included LSpos during RA filling and LSneg representing RA active contraction (their summation is LStot), the phasic RA volumes, total RA emptying fraction, and the ratio of RA passive and active emptying to total emptying...

BACKGROUND: Ejection fraction (EF) is commonly applied as a clinically relevant metric to assess ventricular function. The numerical value of EF depends on the interplay between end-systolic volume (ESV) and end-diastolic volume (EDV). Remarkably, the relative impact of the two constitutive components on EF received little attention. METHODS: Three patient groups not using beta-blockers were analyzed for a robust investigation into the relative contribution of ESV and EDV when assessing EF: cardiac patients (N=155) with left ventricular (LV) data obtained by biplane ventriculography, near-normals (N=276) by gated SPECT investigation, and an MRI-based post Fallot repair study including right ventricular (RV) data (N=124), besides LV...

Heart failure remains a major public-health problem with an increase in the number of patients worsening from this disease. Despite current medical therapy, the condition still has a poor prognosis. Heart failure is complex but mitochondrial dysfunction seems to be an important target to improve cardiac function directly. Our goal was to analyze the effects of MitoQ (100 µM in drinking water) on the development and progression of heart failure induced by pressure overload after 14 weeks. The main findings are that pressure overload-induced heart failure in rats decreased cardiac function in vivo that was not altered by MitoQ...
