Abstract
Pulmonary hypertension (PH) is usually associated with a normal or decreased cardiac output (CO). Less commonly, PH can occur in the context of a hyperdynamic circulation, characterized by high CO (>8 L/min) and/or cardiac index ≥4 L/min/m2 in the setting of a decreased systemic vascular resistance. PH due to high CO can occur due to multiple conditions and in general remains understudied. In this review article we describe the pathophysiology, etiology, diagnosis, hemodynamic characteristics, and management of PH in the setting of high CO. It is important to recognize this distinct entity as PH tends to improve with treatment of the underlying etiology and PH specific therapies may worsen the hemodynamic state.

Abstract
INTRODUCTION The efficacy of endothelin receptor antagonists (ERAs) in the management of Eisenmenger syndrome (ES) remains controversial. The aim of this study is to systemically review the safety and effects of ERAs in improving the quality of life and basic cardiac functions of these patients. METHODS Twelve databases were searched, including PubMed, Web of Science, Scopus, Virtual Health Library, World Health Organization (WHO) Global Health Library, Google Scholar, POPLINE, Systems for Information of Grey Literature in Europe, New York Academy of Medicine, ClinicalTrials.gov, metaRegister of Controlled Trials and the WHO International Clinical Trials Registry Platform, through August 2016. We included randomized clinical trials addressing the effect of ERAs on cardiac functions in patients with ES. The quality of studies was assessed using the Cochrane Collaboration tool. RESULTS We included two trials represented by four papers, of which three papers reported the efficacy of bosentan against placebo and one paper reported the results of a combination of bosentan and sildenafil versus placebo and bosentan. One trial showed a significant effect of bosentan treatment over placebo on indexed pulmonary vascular resistance and mean pulmonary artery pressure, but a non-significant increase in 6-min walk distance and a non-significant effect on systemic pulse oximetry. The other trial reported the safe but non-significant effect of combination therapy of bosentan and sildenafil compared with bosentan and placebo. CONCLUSIONS This study demonstrated safety and improved hemodynamic effects of bosentan in ES, with a controversial effect on exercise capacity. Further randomized controlled trials with longer follow-up duration are needed to confirm these results.

Abstract
Advancement in correction or palliation of congenital cardiac lesions has greatly improved the lifespan of congenital heart disease patients, resulting in a rapidly growing adult congenital heart disease (ACHD) population. As this group has increased in number and age, emerging science has highlighted the systemic nature of ACHD. Providers caring for these patients are tasked with long-term management of multiple neurologic, pulmonary, hepatic, renal, and endocrine manifestations that arise as syndromic associations with congenital heart defects or as sequelae of primary structural or hemodynamic abnormalities. In this review, we outline the current understanding and recent research into these extra-cardiac manifestations.

Abstract
Pulmonary hypertension is the commonest condition leading to dilated pulmonary artery. We describe three different types of compression of adjacent anatomical structures by dilated pulmonary arteries. We included involvement of the left main coronary artery, left recurrent laryngeal nerve and tracheobronchial tree. Compression of these structures can cause major complications such as myocardial ischemia, hoarseness and major airway stenosis. We present a case for each scenario and review the literature for each of these complications, focusing on patients' characteristics and contemporary management.

Abstract
This study aims to estimate plasma levels of acylated ghrelin in children with pulmonary hypertension (PH) associated with congenital heart disease (CHD) and to correlate the levels of acylated ghrelin with endothelin-1 (ET-1), nitric oxide (NO), and clinical hemodynamic parameters. We investigated the plasma concentration of acylated ghrelin, ET-1, NO, and the hemodynamic parameters in 20 children with CHD, 20 children with PH-CHD, and 20 normal children. Plasma-acylated ghrelin and NO levels were significantly higher in CHD group than in control subjects (P < 0.001). Moreover, plasma-acylated ghrelin, ET-1, and NO levels were significantly elevated in PH-CHD group compared with the CHD group (P < 0.05). In PH-CHD children, plasma-acylated ghrelin levels correlated positively with pulmonary artery systolic pressure (PASP; r = 0.740, P < 0.001), pulmonary artery diastolic pressure (PADP; r = 0.613, P = 0.004), right ventricular systolic pressure (RVSP; r = 0.642, P = 0.002), mean pulmonary arterial hypertension (mPAP; r = 0.685, P = 0.001), right ventricle diameter (RVD; r = 0.473, P = 0.035), pulmonary artery trunk diameter (PAD; r = 0.613, P = 0.004), NO (r = 0.463, P = 0.04), and ET-1 (r = 0.524, P = 0.018). Plasma-acylated ghrelin levels were elevated both in CHD and in PH-CHD. Increased acylated ghrelin levels correlated positively with ET-1, NO, PASP, PADP, RVSP, mPAP, RVD, and PAD. Acylated ghrelin may be a new biomarker of PH-CHD.

Abstract
Proper and early identification of patients who harbor serious occult illness is the first step in developing a disease-management strategy. Identification of illnesses through the use of noninvasive techniques provides assurance of patient safety and is ideal. PA dilation is easily measured noninvasively and is due to a variety of conditions, including pulmonary hypertension (PH). The clinician should be able to thoroughly assess the significance of PA dilation in each individual patient. This involves knowledge of the ability of PA dilation to accurately predict PH, understand the wide differential diagnosis of causes of PA dilation, and reverse its life-threatening complications. We found that although PA dilation is suggestive of PH, data remain inconclusive regarding its ability to accurately predict PH. At this point, data are insufficient to place PA dilation into a PH risk-score equation. Here we review the causes and complications of PA dilation, define normal and abnormal PA measurements, and summarize the data linking its association to PH, while suggesting an algorithm designed to assist clinicians in patient work-up after recognizing PA dilation.

Abstract
Pulmonary arterial hypertension (PAH) is an obstructive pulmonary vasculopathy, characterized by excess proliferation, apoptosis resistance, inflammation, fibrosis, and vasoconstriction. Although PAH therapies target some of these vascular abnormalities (primarily vasoconstriction), most do not directly benefit the right ventricle (RV). This is suboptimal because a patient's functional state and prognosis are largely determined by the success of the adaptation of the RV to the increased afterload. The RV initially hypertrophies but might ultimately decompensate, becoming dilated, hypokinetic, and fibrotic. A number of pathophysiologic abnormalities have been identified in the PAH RV, including: ischemia and hibernation (partially reflecting RV capillary rarefaction), autonomic activation (due to G protein receptor kinase 2-mediated downregulation and desensitization of β-adrenergic receptors), mitochondrial-metabolic abnormalities (notably increased uncoupled glycolysis and glutaminolysis), and fibrosis. Many RV abnormalities are detectable using molecular imaging and might serve as biomarkers. Some molecular pathways, such as those regulating angiogenesis, metabolism, and mitochondrial dynamics, are similarly deranged in the RV and pulmonary vasculature, offering the possibility of therapies that treat the RV and pulmonary circulation. An important paradigm in PAH is that the RV and pulmonary circulation constitute a unified cardiopulmonary unit. Clinical trials of PAH pharmacotherapies should assess both components of the cardiopulmonary unit.

Abstract
OBJECTIVE To report our single-center experience with patients who had cardiac and multiorgan transplantation for end-stage congenital heart disease (CHD). PATIENTS AND METHODS We reviewed records for all patients with CHD who had undergone heart transplantation at Mayo Clinic, Rochester, Minnesota, from November 1, 1990, through June 30, 2012. Patients with cardiomyopathy were excluded, unless CHD was present. RESULTS Overall, 45 patients had cardiac transplantation for end-stage CHD (mean age, 26.1±18.4 years; range, 1 month to 65 years). Two patients (4%) had combined heart/liver transplantation; 1 (2%) had heart/kidney transplantation. Six patients (13%) had no previous cardiac operation; the remaining 39 patients had a mean of 3 (range, 1-8) previous cardiac operations. Patient survival (95% CI) at 1, 5, and 10 years was 89% (80%-98%), 89% (80%-98%), and 72% (56%-87%), respectively, while graft survival at 1, 5, and 10 years was 89% (80%-98%), 89% (80%-98%), and 61% (44%-78%), respectively. During the same era, the International Society for Heart & Lung Transplantation reported that survival in patients undergoing transplant for non-congenital diagnoses was 85%, 72%, and 56%, respectively. Over a mean follow-up of 8.7±6.2 years, rejection requiring treatment was documented in 35 patients (78%). Eleven patients (24%) have been diagnosed with neoplasia (8 skin, 1 blood, 1 lymph, and 1 other), and 3 patients (7%) have required retransplantation. Four patients (9%) have developed significant coronary vasculopathy; 1 successfully underwent retransplantation, and 3 died 6, 8, and 14 years after transplantation. CONCLUSION With appropriate patient selection and posttransplant monitoring, survival has improved for patients with complex end-stage CHD. Multiorgan transplantation is an option for selected patients with CHD.

Abstract
Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease, with high morbidity and mortality rates. Accumulating evidence has demonstrated that genetic defects play an important role in the pathogenesis of TOF. However, the molecular basis of TOF in the majority of patients remains to be determined. In the present study, sequence analysis of the coding exons and exon-intron boundaries of GATA5, a gene encoding a zinc finger‑containing transcriptional factor crucial for cardiogenesis, was performed on genomic DNA isolated from resected cardiac tissue and matched blood samples of 85 unrelated patients who underwent surgical repair of TOF. Genotyping was performed on the cardiac tissue and matched blood samples from 63 unrelated patients who underwent cardiac valve replacement due to rheumatic heart disease as well as the blood samples obtained from 200 unrelated healthy individuals. The functional effect of the mutations was evaluated by using a luciferase reporter assay system. As a result, the novel heterozygous GATA5 mutations, p.D203E and p.Y208X, were found in the cardiac tissues of two TOF patients, respectively. There were no mutations in the cardiac tissues obtained from 63 patients with rheumatic heart disease nor in the blood samples obtained from the 348 subjects. Functional analysis revealed that the GATA5 mutants were consistently associated with significantly decreased transcriptional activity compared with their wild-type counterpart. Thus, results of this study showed an association of somatic GATA5 mutations with TOF, providing further insight into the underlying molecular mechanism of TOF.
