Thoracic Bio-reactance Measurement of Cardiac Output in Pulmonary Hypertension

Pulmonary Hypertension (PH) is a rare disease characterized by an increase in pulmonary vascular resistance, leading to a progressive decline in cardiac output (CO).Since cardiac output is correlated with the prognosis of the disease, the conduct of a right heart catheterization (thermodilution measurement, reference technique) during the annual follow-up visit of patients in competences centres is recommended. In practice, it is not systematically performed because of it is invasive, with potential risk for the patient, and there is limited logistical capacity for its implementation. The estimation of cardiac output is thus often based on cardiac ultrasound but its measurement is potentially biased. Starling ™ SV is a non-invasive cardiac output monitor based on thoracic bio-reactance measurement. Several clinical studies have shown that cardiac output measured by bio-reactance is strongly correlated with the measurement obtained by catheterization in different indications. Rich et al. (2013) assessed bio-reactance specifically in 50 patients with Pulmonary Hypertension compared with thermodilution. The results showed that the measurement of cardiac output by bio-reactance was feasible in these patients, had a better accuracy than by catheterization, and was reliable for detecting changes in cardiac output after a vasodilatation test. The Starling ™ SV monitor could thus have a place in the follow-up of patients who are being treated for Pulmonary Hypertension. Since it is a rapid, non-invasive examination, it could be performed on an outpatient basis, especially as a first-line test to check the stability of the CO, thus avoiding the systematic use of right heart catheterization, which would then be reserved only to patients for whom the measurement by bio-reactance would show a decrease of cardiac output compared to the previous value. Before being able to propose this use in current practice, it is necessary to carry out a pilot study which will make it possible to explore the interest of bio-reactance in this situation.

Frailty in Children With Cardiac Disease

Frailty is a complex biologic syndrome of diminished physiologic reserve that leads to decreased resistance to stressors and is associated with adverse health outcomes. The syndrome has been well studied in adults and is quantified by the Fried criteria, which are comprised of five components- slowness, weakness, self-reported exhaustion, shrinkage and diminished physical activity. The concept of frailty is novel in children. A study in young adult childhood cancer survivors demonstrated increased incidence of frailty in this population along with increased risk of morbidity and mortality. This suggests that frailty as a phenotype has relevance outside of the geriatric age group. Pediatric patients with single ventricle physiology, heart failure and pulmonary artery hypertension- all represent populations with significantly increased risk of mortality, morbidity and decreased quality of life. Currently, such patients are monitored outpatient by serial echocardiograms and blood work that only gives information about end organ damage. But there is no validated tool available to measure global infirmity in such children. Better understanding of the relevance and applicability of frailty in pediatrics may allow for identification of the most vulnerable pediatric cardiac patients and be of value in optimizing their clinical management and improving health outcomes.

Database for Clinical and Anamnestic Data in Pulmonary Hypertension

Pulmonary hypertension (PH) is defined as a pulmonary arterial mean pressure (meanPAP) ? 25 mmHg measured in the right heart catheterization. There are different forms of PH defined in the classification of Dana Point 2008. PH is diagnosed with right heart catheterization but there are other non invasive methods which can be used for screening like the echocardiography, stress echocardiography and cardio pulmonary exercise testing. In the diagnosis process and in the follow up of PH patients biomarkers like NTproBNP are helpful. There are no specific biomarkers for the disease which can make the diagnosis process easier and predict prognosis. The systematic data collection in a data base provides better information about patients in daily routine and clinical studies as well as in the design of new studies.

Non-contrast Enhanced Cardiac Magnetic Resonance Imaging in the Diagnosis and Classification of Pulmonary Hypertension

Pulmonary hypertension (PH) is a life-threatening cardiovascular disease characterized by pathological elevation of mean pulmonary arterial pressure (mPAP) >/= 25 mmHg at rest. mPAP < 20 mmHg is defined as normal, values in the range between 21-24 mmHg are described as "borderline PH" diagnosed by right heart catheterization. Based on the etiology, PH is assigned to 5 groups (WHO, Data Point, 2008), whereas classification of disease is an important prognostic and therapy-deciding criterion. Cardiac magnetic resonance tomography (CMR) provides a reliable technique to estimate elevated mean pulmonary arterial pressure from period of existence of a vortical motion of blood flow in the main pulmonary artery. Vortex can be visualized in 3-dimensional vector field, particle trace and streamline representations and can be analysed with respect to vortex related measures (geometry of center, vortex formation, vorticity, propagation dynamics …). Furthermore T1-mapping and non-contrast enhanced lung perfusion/ventilation scans represent promising techniques for PH characterization. Aim of this explorative study is to 1. analyse PH-associated blood flow characteristics in the heart and the surrounding great vessels with respect to the 5 groups of PH, and 2. investigate the hemodynamic state of "borderline PH" compared to normal mPAP and manifest PH by non-contrast CMR.

The Effects of Commercial Air Travel on Patients Suffering From Pulmonary Hypertension

The aim of this study is to 1) descriptively report possible in flight events and 2) to provide regression analysis if the number of events are statistically significant in their prevalence and thus are useful in finding possible parameters in echocardiography, right heart catheterization, laboratory findings, spiroergometry as well as six minute walk test to produce a risk assessment for possible expected in flight adverse events as well as a recommendation concerning the need of supplemental oxygen for each individual patient. The investigators therefore want to find out: In which subgroup (if applicable) of PH patients in flight adverse events are more frequent. Whether there are parameters (from blood samples, blood gas analysis, World Health Organization-Functional Class (WHO-FC), Six Minute Walk (SMW), echocardiography, right heart catheter (RHC)) that are able to predict in flight need for additional oxygen and/or possible adverse events.

Novel Echocardiographic Methods for Early Identification of Neonates at Risk for Chronic Pulmonary Hypertension

Chronic pulmonary hypertension (cPHT) is a serious cardiopulmonary disorder that causes low oxygen levels in the blood, difficulty in breathing and ultimately heart failure. Newborn babies born extremely premature frequently suffer from cPHT while receiving treatment in neonatal intensive care units and are more likely to die than those without cPHT. Echocardiography is the investigation of choice for the assessment of heart function in premature infants however however there is a significant lack of standardization, sensitivity, and reliability for echocardiography parameters and a lack of consensus regarding optimal detection timing. In adults and older children it is known that early diagnosis and treatment, particularly before right side of the heart fails, is an important determinant of treatment success and survival. Diagnosis late in postnatal course for preterm infants remains a major barrier to timely and effective treatment. The primary objective of this study is to develop new, sensitive, quantitative echocardiographic diagnostic criteria which will allow for the identification of extreme preterm neonates suffering from significantly high pressure in their pulmonary blood vessels, early in postnatal course, when the disease is likely to be most amenable to preventative/curative treatment. This is an international initiative that will leverage expertise about echocardiography techniques and cardiopulmonary physiology of preterm infants.The results of this study will have an immediate impact on the day-to-day care of these highly vulnerable infants. The results will lead to increased awareness among clinicians, inform future surveillance protocols and diagnostic timing, and provide ideal preparation for future therapeutic trials.

L-citrulline and Pulmonary Hypertension Associated With Bronchopulmonary Dysplasia

Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects up to 35% of very low birth weight infants (VLBW < 1500 g). Based on the current numbers of VLBW infants born annually in the U.S., between 5,000-10,000 neonates will develop BPD each year. It is estimated that 8-42% of infants with BPD will develop pulmonary hypertension (PH). Moreover, it has been known since the 1980's that echocardiographic evidence of PH in infants with BPD is associated with up to 40% mortality. Treatment options to ameliorate PH in infants with BPD (BPD-PH) are limited. There have been no randomized clinical trials of any therapy in infants with BPD-PH. The standard care for the management of BPD-PH is to attempt to resolve the underlying lung disorder and the judicious use of oxygen as a potent pulmonary vasodilator. Using this management approach, which has not changed since the 1980's, the survival rates for infants with BPD-PH in the 2000's has been reported to be 64% at 6 months and 53% at 2 years after diagnosis of PH. The lack of improvement in outcomes for the past 3 decades has led to the widespread agreement that novel and effective therapies are desperately needed for infants with BPD-PH. The goal is to develop oral L-citrulline clinically for the treatment of pediatric pulmonary hypertension associated with bronchopulmonary dysplasia (BPD-PH); before pursuing a large scale treatment trial, pharmacokinetic (PK) dose-finding, tolerability studies in patients at high risk of developing BPD-PH are warranted. The hypothesis is that oral L-citrulline will be well tolerated, without significant adverse effects in infants at high risk of developing pulmonary hypertension (PH) associated with BPD. The investigators propose to first characterize the PK profile of oral L-citrulline in order to define an appropriate dose range and treatment interval for infants at high risk of developing BPD-PH. Then using the doses and intervals generated by the PK profile, with a maximum dose of 3 g/kg/d, the investigators propose to evaluate the tolerability and ability to achieve the target study drug level (100-150 micromolar) in babies treated for 72 hours with oral L-citrulline. These studies will provide the data needed to design a full-scale randomized multi-center trial to evaluate the efficacy of oral L-citrulline therapy to ameliorate BPD-PH in human infants, a patient population that has a desperate need of new therapies.

Anxiety Self-management Intervention for Pulmonary Hypertension

Pulmonary hypertension (PH) is a disorder of high blood pressure that impacts the heart and lungs. Approximately, 50% of individuals with PH experience anxiety or panic disorders. There is limited evidence on psychological treatments for anxiety in PH; however, results support the use of Cognitive Behavioural Therapy (CBT). Despite the prevalence and impact of anxiety in PH; there are no widely available and/or disease specific pathways, thus highlighting an unmet need in this population. This project aims to develop and pilot, using randomised control trial methodology, a self-management intervention for individuals with PH based on principles of CBT.
