Heart Catheterization Using Magnetic Resonance Imaging (MRI) Fluoroscopy and Passive Guidewires
Background: A heart catheterization is a diagnostic heart procedure used to measure pressures and take pictures of the blood flow through the heart chambers. Magnetic resonance imaging (MRI) fluoroscopy shows continuous pictures of the heart chambers that doctors can watch while they work. Researchers want to test this procedure with catheterization tools routinely used in x-ray catheterization called guidewires. Guidewires will help move the heart catheter through the different heart chambers. Guidewires are usually considered unsafe during MRI because MRI can cause a guidewire to heat while inside the blood vessels and heart....

Hemodynamic Effect of Nasal High-flow in Patients Suspected or Followed for a Precapillary Pulmonary Hypertension
In this study, the investigators aim to describe the hemodynamic consequences of nasal high-flow measured during right heart catheterization and echocardiography. The research hypothesis is that nasal high-flow would increase cardiac output in patients with pulmonary hypertension. The concomitant echocardiography will allow to describe its sensibility to detect cardiovascular consequences of nasal high-flow.

Hemodynamic Effects of BPA at Rest and During Exercise in CTEPH
Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by obstruction of the pulmonary vasculature by residual organized thrombi, leading to increased pulmonary vascular resistance (PVR), progressive pulmonary hypertension, and right heart failure. Medical therapy and balloon angioplasty (BPA) are effective treatment alternatives in lowering pulmonary pressures and increasing pulmonary flow. The aim of this study is to assess the hemodynamic effects of BPA or medical therapy on the pressure-flow relationship in the pulmonary vasculature and the pulmonary vascular compliance.

Hemodynamic Testing Strategies to Assess Pulmonary Hypertension in Heart Failure
The goal of this observational study is to learn about heart function and high lung blood pressure in patients with heart failure. The main question[s] it aims to answer are whether we can improve the ability to predict patients who will have complications after they receive treatment including heart transplant and left ventricular assist devices.

Hormonal, Metabolic, and Signaling Interactions in PAH
Our hypothesis is that optimal treatment of the dysfunctional metabolic pathways which underlie PAH will improve pulmonary vascular function and consequences of the disease.

HRV as a Marker of Treatment Response in PAH Arterial Hypertension
This is a prospective longitudinal cohort study to determine the value of HRV obtained using noninvasive actigraphy to quantify the response to pulmonary vasodilator therapy in newly diagnosed PAH patients

Hyperpolarized 129Xe MR Imaging of Lung Function in Healthy Volunteers and Subjects With Pulmonary Disease
The purpose of this study is to develop and evaluate the usefulness of hyperpolarized (HP) 129Xe gas MRI for regional assessment of pulmonary function.

Identification of Heritable CTEPH
Some patients who have blood clots come down with a life-threatening condition known as Chronic Thromboembolic Pulmonary Hypertension (CTEPH), which is high blood pressure only in the arteries of the lungs. This study seeks to understand more about the genetics causes of CTEPH by obtaining blood samples and examining family histories.

Identifying Right Ventricular Dysfunction in COPD Through Right Heart Catheterization, Imaging and Exercise
This study plans to learn more about heart function among individuals with chronic obstructive pulmonary disease (COPD). In particular, the investigators want to understand the different patterns of right ventricular response to pulmonary hypertension (high pressure in the lungs) during rest and exercise. By identifying patterns of right ventricular dysfunction, this study will help identify better treatments for patients with COPD in the future.
