Filter by:Despite the developments in recent years, pulmonary arterial hypertension (PAH) is still a disease with high mortality and morbidity. Although studies on genetic background have increased, the pathogenesis of PAH remains complex and unresolved. The most comprehensive data are related to bone morphogenetic protein receptor type 2 (BMPR2), and in recent years, new responsible or candidate genes have been identified, especially by new generation DNA sequencing In this study, it was aimed to determine the genetic background of patients with PAH and to investigate the genetics of secondary PAH not only HPAH.
This clinical investigation is a prospective, multicenter, non-randomized, open-label, Early Feasibility Study to evaluate the safety, performance, and initial clinical efficacy of the Rivet PVS therapy in patients with symptomatic pulmonary hypertension.
Russian National Registry of Patients With Pulmonary Arterial Hypertension (PAH) and Chronic Thromboembolic Pulmonary Hypertension (CTEPH) is a multicenter, observational study of the clinical course and disease management of PAH and CTEPH patients. designed to gather demographic, clinical and prognostic data of routine medical care in prospective manner for newly initiated treatment since Jan 2016. The internet-based registry (www.medibase.pro) fulfills high quality standards through several measures (planned minimum centre contribution of at least 10 patients per year, automated plausibility checks of data at entry, queries, monitoring with source data verification in >50% of participating centers). All consecutive patients diagnosed with World Health Organization Pulmonary Hypertension Groups (WHO Group I) PAH according to specific hemodynamic criteria will be enrolled in participating centers after signing the informed consents. Participating patients will be followed for a minimum of five years from the time of enrollment. It can be applied, among further purposes, for quality assurance: individual centers can confidentially compare their results with the combined outcome of the other centers. It is expected that the registry contributes to optimization of specific drug therapy for PAH and Pulmonary Hypertension (PH).
Study ROR-PH-303, ADVANCE EXTENSION, is an open-label extension (OLE) study for participants with WHO Group 1 PAH who have participated in another Phase 2 or Phase 3 study of ralinepag.
The purpose of this study is to (1) quantify cardiovascular anatomy and physiology using magnetic resonance imaging under both resting and exercise conditions in patients who have congenital heart disease and in age-matched normal volunteers, (2) use computer models to reproduce and simulate blood flow in these patients, and then (3) to combine the imaging data and computer models to estimate values which cannot be directly measured and to predict physiological changes induced by exercise and medical or surgical therapies.
The RELAHP registry is a Latin-American multinational, multicenter, prospective observational registry-type cohort study, which pretends to identify clinical characteristics, clinical course, management and outcome of all forms of pulmonary hypertension (PH). All consecutively consented patients newly diagnosed with WHO Group I-V PH according to specific hemodynamic criteria on right heart catheterization at the participating centers will be enrolled. Patients will be followed six-monthly for a minimum of five years from the time of enrollment.
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 purpose of this study is to determine whether cardiac resynchronization therapy with the use of an implanted electronic pacemaker reduces morbidity associated with chronic thromboembolic pulmonary hypertension
