RECRUITING

Contrast Echocardiography During Exercise to Assess Pulmonary Blood Volume

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of this study is to evaluate whether pulmonary blood volume (PBV) derived from contrast echocardiography can serve as a non-invasive surrogate for invasive pulmonary artery wedge pressure (PAWP) during exercise. Also, to compare changes in PBV with exercise in patients with and without heart failure and pulmonary vascular disease.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * Patients referred to the cardiac catheterization laboratory for invasive exercise right heart catheterization for evaluating exertional dyspnea. Investigators will include patients with normal or low EF, and across the spectrum of pulmonary hypertension severity.
  1. * Patient inability or unwillingness to undergo echocardiography including a contrast method, or if echocardiography would, in the opinion of the investigator, somehow compromise the quality of data acquisition for the clinical case.
  2. * Prior adverse reaction to echo contrast administration
