Filter by:The knowledge on the rare type of pulmonary hypertension which can not be explained by left heart disease, respiratory disease or congenital heart disease is very limited. Investigators aim to setup a national registration study for the rare type of pulmonary hypertension, to understand the natural history, survival, progression, genetic and environmental contributions to disease.
Respiratory monitoring during right heart catheterization to differentiate between various types of pulmonary hypertension; The effects of the cardiovascular system on the lung mechanical properties.
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: 1. In which subgroup (if applicable) of PH patients in flight adverse events are more frequent. 2. 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.
This study aims to investigate safety and efficacy of Occlutech® AFR device in patients with severe pulmonary hypertension (PH).
Since the pulmonary artery hypertension is defined based on MPAP and the two previous formulae relating MPAP and PAT were derived in western population, the investigator planned to conduct a prospective study to derive a new formula for measuring MPAP from PAT in Indian population and compare the accuracy of all the three formulae
Tracheal occlusion IDE approved by FDA for congenital diaphragmatic hernia fetuses.
This study is designed as a prospective study, with the primary endpoint being changes in pulmonary hemodynamic parameters after ELVR in patients with severe emphysema. Secondary endpoints will be changes in lung function parameters, exercise capacity, and QoL.
Development of pulmonary hypertension (PH) in chronic lung diseases has both functional and prognostic implications . PH in Lung diseases is usually mild to moderate with preserved cardiac output, and evolves slowly alongside the progression of lung disease and hypoxemia . However, a minority of patients develop severe PH with elevations in pulmonary artery pressure that have been described as ''out of proportion'' to the underlying disease . The aim of this study is to compare the characteristics and outcomes of consecutive patients with PH-due to lung diseases diagnosed at our specialist referral center over a 1-year period.
- Measuring the incidence and prevalence of PAH in Egyptian patients with different types of MCD - Determination of survival & the risk factors of mortality.
The purpose of this study is to verify the applicability Six minutes walk test and Shuttle walk test in assessing functional capacity in patients with Eisenmenger Syndrome. Patients will undergo three functional tests, being the six-minute walk test, shuttle walk test and cardiopulmonary exercise test on a cycle ergometer, associated with evaluation of metabolic and ventilatory variables and cardiac monitoring throughout the test.
