irculatory support.The heart is a complex multi-scale system composed of components integrated at the subcellular, cellular, tissue and organ levels. The myocytes, the contractile elements of the heart, form a complex three-dimensional (3D) network which enables propagation of the electrical signal that triggers the contraction to efficiently pump blood towards the whole body. Cardiovascular diseases (CVDs), a major cause of mortality in developed countries, often lead to cardiovascular remodeling affecting cardiac structure and function at all scales, from myocytes and their surrounding collagen matrix to the 3D organization of the whole heart. As yet, there is no consensus as to how the myocytes are arranged and packed within their connective tissue matrix, nor how best to image them at multiple scales. Cardiovascular imaging is routinely used to investigate cardiac structure and function as well as for the evaluation of cardiac remodeling in CVDs. LY2880070 in vitro For a complete understanding of the relationship between structural remodelingew, we provide an overview of available and emerging cardiovascular imaging techniques for assessing myocardial architecture ex vivo and discuss their utility in being able to quantify cardiac remodeling, in CVDs, from myocyte to whole organ.Reverse Potts shunt is a palliative procedure aimed at decompressing the pressure-overloaded right ventricle in severe pulmonary hypertension (PH). We, herein, report the first case of an interventional creation of an "endogenous" reverse Potts shunt by stenting a pre-existing small but patent ductus arteriosus (PDA) in a 2 months old female infant with severe, supra-systemic PH, associated with a novel combination of a compound heterozygous ABCA3 mutation and additional heterozygous genetic variants of surfactant protein B (SFTPB) and C (SFTPC). The aforementioned combination of human genetic mutations has not been described before in viable infants, children or adults. The catheter intervention was performed via percutaneous femoral arterial access and was well-tolerated. Subsequently, the infant improved by means of clinical status, echocardiographic systolic right ventricular (RV) function, and serum NT-proBNP levels as biomarker of right atrial and RV pressure load. In conclusion, this single case report suggests that interventional stenting of a pre-existing PDA to create an "endogenous" reverse Potts shunt is feasible and efficacious in infants less than 3 months old with severe PH and impending RV failure associated with developmental lung disease.Prenatal closure of the ductus arteriosus (DA) can lead to cardiovascular dysfunction resulting in pulmonary hypertension (PH), progressive right heart failure, fetal hydrops, and fetal or neonatal demise. Supportive therapies-including mechanical ventilation, oxygen, and nitric oxide (NO)-have been employed with variable success among infants born full term, but there is no widely accepted management of prenatal closure of the DA, particularly for preterm infants. We present the case of an infant born at 31 weeks' gestation with right ventricular (RV) dysfunction and PH due to prenatal ductal closure, who was successfully treated with milrinone, resulting in full recovery of cardiac function. Prenatal ductal closure is rare, particularly under 32 weeks gestation, but should be suspected in cases of postnatal hypoxemia in the absence of significant lung disease or structural heart disease. Milrinone may be considered as a therapeutic agent to treat both PH and RV dysfunction in preterm infants status post in utero closure of the DA.Bronchopulmonary dysplasia (BPD) is a combined pulmonary vascular and parenchymal disease, representing the most common cause of chronic lung disease (CLD) in infancy. Pulmonary hypertension (PH) is frequently associated with BPD and-if persistent-substantially increases mortality. We report on a 4-month-old, former preterm infant with BPD, severe PH and right heart failure who greatly and rapidly improved clinical status and right ventricular (RV) function by means of blood biomarkers [N-terminal prohormone of brain natriuretic peptide (NT-pro-BNP), cardiac troponin T] and transthoracic echocardiography, following the addition of spironolactone and hydrochlorothiazide to the treatment regimen.
Macitentan, a dual endothelin receptor antagonist (ERA), was approved in 2014 for the treatment of adults with idiopathic pulmonary arterial hypertension (PAH). Once-per-day dosing and low potential hepatic toxicity make macitentan an appealing therapeutic option for children with PAH, but reports on its use in pediatric patients are still lacking.
Prospective observational study of 18 children [10 male; median age 8.5, minimum (min.) 0.6, maximum (max.) 16.8 years] with pulmonary hypertension (PH). Four of these 18 patients were treatment-naïve and started on a de novo macitentan therapy. The remaining 14/18 children were already on a PH-targeted pharmacotherapy (sildenafil or bosentan as monotherapy or in combination). Nine children who were on bosentan were switched to macitentan. We analyzed the 6-minute walking distance (6MWD), NYHA functional class (FC)/modified ROSS score, invasive hemodynamics, echocardiographic variables and the biomarker N-terminal pro-brain natriuretic peptide (NT-proBNP).
Thd and was associated with improvements in invasive hemodynamics, longitudinal systolic RV function (TAPSE) and serum NT-proBNP values.
This is the first prospective study of macitentan pharmacotherapy in infants and children with PH less then 12 years of age. Except in one patient, macitentan treatment was well tolerated and was associated with improvements in invasive hemodynamics, longitudinal systolic RV function (TAPSE) and serum NT-proBNP values.Right heart dysfunction and failure is the principal determinant of adverse outcomes in patients with pulmonary arterial hypertension (PAH). In addition to right ventricular (RV) dysfunction, systemic congestion, increased afterload and impaired myocardial contractility play an important role in the pathophysiology of RV failure. The behavior of the RV in response to the hemodynamic overload is primarily modulated by the ventricular interaction and its coupling to the pulmonary circulation. The presentation can be acute with hemodynamic instability and shock or chronic producing symptoms of systemic venous congestion and low cardiac output. The prognostic factors associated with poor outcomes in hospitalized patients include systemic hypotension, hyponatremia, severe tricuspid insufficiency, inotropic support use and the presence of pericardial effusion. Effective therapeutic management strategies involve identification and effective treatment of the triggering factors, improving cardiopulmonary hemodynamics by optimization of volume to improve diastolic ventricular interactions, improving contractility by use of inotropes, and reducing afterload by use of drugs targeting pulmonary circulation.
