Pulmonal hypertension

S Riechardt, M Koch, J Oh, M Fisch
BACKGROUND: Neonatal autosomal recessive polycystic kidney disease (ARPKD) is associated with giant kidneys, lung hypoplasia, pulmonal hypertension, and end-stage renal failure. Depending on the study, mortality is reported to range between 20 and 80%. OBJECTIVES: Does bilateral nephrectomy improve survival? PATIENTS AND METHODS: Between 2010 and 2016, we treated 7 children with prenatally diagnosed ARPKD. All had a planned delivery by cesarean section...

KEY POINTS: Maternal nutrient restriction induces intrauterine growth restriction (IUGR) and leads to heightened cardiovascular risks later in life. We report right ventricular (RV) filling and ejection abnormalities in IUGR young adult baboons using cardiac magnetic resonance imaging. Both functional and morphological indicators of poor RV function were seen, many of which were similar to effects of ageing, but also with a few key differences. We observed more pronounced RV changes compared to our previous report of the left ventricle, suggesting there is likely to be a component of isolated RV abnormality in addition to expected haemodynamic sequelae from left ventricular dysfunction...

In the adult congenital heart disease (ACHD) population, pulmonary valve replacement (PVR) is a common intervention, its benefit, however, has been incompletely investigated. This study investigates short- and intermediate-term outcomes after PVR in ACHD. Using State Inpatient Databases from the Healthcare Cost and Utilization Project, we investigated both hospitalization rate and financial burden accrued over the 12-month period after PVR compared with the 12 months before. Among 202 patients who underwent PVR, per patient-year hospitalization rates doubled in the year after PVR compared with the year before (0...

The population of adults with tetralogy of Fallot (TOF) is growing, and it is not known how the changes in age distribution, treatment strategies, and prevalence of co-morbidities impact their interaction with the health care system. We sought to analyze the frequency and reasons for hospital admissions over the past decade. We extracted serial cross-sectional data from the United States Nationwide Inpatient Sample on hospitalizations including the diagnostic code for TOF from 2000 to 2011. From 2000 to 2011, there were 20,545 admissions for subjects with TOF, with a steady increase in annual number...

Congenital lobar emphysema is a rare disease, which is characterized by pulmoner hyperinflation. Depending on the degree of bronchial obstruction, the clinical presentation may be variable. We report a rare case with congenital lobar emphysema in a 38-days-old male infant who presented with severe respiratory distress and hypertension. Air trapping in the left upper lung and significant mediastinal shift to the right were observed on the chest x-ray. Emphysematous changes were detected on the thorax computed tomography and considered as congenital lobar emphysema...

Right-sided heart failure is the most common cause of death in pulmonary hypertension (PH). Echocardiographic measurements of right atrial (RA) size are associated with worse outcome in PH, however the association between RA function and death in PH has not been well-described. 160 PH patients (World Health Organization groups 1-5) underwent cardiac magnetic resonance imaging (cMRI) and right heart catheterization (RHC) within 6 weeks of each other at a tertiary care academic medical center in the United States...

BACKGROUND: Mutations in the KCNK3 gene have been identified in some patients suffering from heritable pulmonary arterial hypertension (PAH). KCNK3 encodes an outward rectifier K(+) channel, and each identified mutation leads to a loss of function. However, the pathophysiological role of potassium channel subfamily K member 3 (KCNK3) in PAH is unclear. We hypothesized that loss of function of KCNK3 is a hallmark of idiopathic and heritable PAH and contributes to dysfunction of pulmonary artery smooth muscle cells and pulmonary artery endothelial cells, leading to pulmonary artery remodeling: consequently, restoring KCNK3 function could alleviate experimental pulmonary hypertension (PH)...

Here, we report a rare case of a 23-year-old term parturient with Eisenmenger syndrome due to Taussig-Bing anomaly presenting with gestational hypertension, oligohydramnios, and intrauterine growth retardation posted for elective cesarean section. Preoperatively, echocardiography of the patient was suggestive of double-outlet right ventricle (DORV) with large sub-pulmonic ventricular septal defect (VSD), right ventricular hypertrophy, bidirectional shunt and severe pulmonary artery hypertension. The surgery was successfully performed under a graded segmental epidural anesthesia with 2% lignocaine...

We reported transcatheter closure of gigantic persistent ductus arteriosus (PDA) complicated by severe pulmonary hypertension (PH) using a custom-made PDA occluder. A 19-year-old lady weighing 45 kg visited to our Heart Saving Project in Mongolia with a chief complaint of shortness of breath. Contrast CT scan showed ellipsoidal section of PDA whose long axis being 28 mm, and the short axis of 21 mm. A custom-made PDA occluder, whose retention skirt, the aortic side, and the pulmonic side diameter of the body were 54, 36, 34 mm, respectively, was successfully deployed using 14-Fr sheath...

While the clinical classification of diseases with pulmonary hypertension (PH) has remained fairly stable in recent years, the treatment options have improved significantly. In addition to the General measures (vaccinations, physical training) new recommendations for supportive therapy (administration of diuretics, iron supplementation and oral anticoagulant) exist currently. Some new substances (mostly in the indication pulmonary arterial hypertension) have been admitted to the targeted drug treatment in recent years...

From a broad perspective there are only three arterial systems that respond to relative hypoxia with vasoconstriction. They are the placental, the pulmonic and the renal vascular beds. The renal system's adaptation to hypoxia is markedly different from the other two circulatory beds and will not be further considered here. Regional vasoconstriction is adaptive in the placenta and lung because it redirects red blood cells from areas of relative hypoxia to more oxygenated areas thereby maximizing oxygen uptake for a given cardiac output...

Pulmonary arterial hypertension (PAH) is a common postoperative complication in patients with congenital heart disease (CHD). Although the recent clinical classification of pulmonary hypertension divided PAH associated with CHD (PAH-CHD) into several subclasses, the anatomical and hemodynamic features of postoperative PAH-CHD vary enormously. Therefore, it is still difficult to obtain clinical evidence supporting the indication of pulmonary vasodilators for PAH-CHD. We often encounter patients with PAH occurring after surgical treatment of tetralogy of Fallot (TOF), especially patients with major aortopulmonary collateral arteries (MAPCAs)...

BACKGROUND: The role of the natriuretic peptides (NPs) in hypertension is complex. Thus, a higher blood NP concentration is a robust marker of pressure-induced cardiac damage in patients with hypertension, whereas genetically elevated NP concentrations are associated with a reduced risk of hypertension and overweight individuals presumably at high risk of hypertension have lower NP concentrations. OBJECTIVE: To investigate the associations between serum N-terminal pro-B-type natriuretic peptide (NT-proBNP), used as a surrogate marker for active BNP, and prevalent as well as 5-year incident hypertension in a Danish general population sample...

OBJECTIVES: To compare noninvasive estimates of pulmonary artery pressure (PAP) obtained via echocardiography (ECHO) to invasive measurements of PAP obtained during right heart catheterization (RHC) across a range of PAP. To examine the accuracy of estimating right atrial pressure via ECHO (RAPECHO) compared to RAP measured by RHC (RAPRHC), and determine if adding RAPECHO improves the accuracy of noninvasive PAP estimations. ANIMALS: 14 healthy female beagle dogs...

INTRODUCTION: Patients with pulmonary hypertension (PH) often present with a variety of physical findings reflecting a volume or pressure overloaded right ventricle (RV). However, there is no consensus regarding the diagnostic utility of the physical examination in PH. METHODS: We conducted a systematic review of publications that evaluated the clinical examination and diagnosis of PH using MEDLINE (1946-2013) and EMBASE (1947-2013). We also prospectively evaluated the diagnostic utility of the physical examination findings...

BACKGROUND AND OBJECTIVE: Since pulmonary hypertension is defined haemodynamically with a mean pulmonary artery pressure (mPAP) of at least 25 mmHg, right heart catheterization is mandatory for diagnosis of PH. However, it remains unclear if echocardiography can always detect a PH and to what extent echocardiographic and invasive parameters correlate. We aimed to determine the frequency of right heart valve insufficiencies, the correlation of mPAP measured invasively and estimated by echocardiography and the correlation of other echocardiographic parameters with invasively measured cardiac output (CO) and pulmonary vascular resistance (PVR) in patients who presented at our center for pulmonary hypertension...
