Overview

The purpose of this study is to determine how accurate transthoracic echocardiogram (echo) is at estimating the pressures within your heart, as compared to the most accurate test of right heart catheterization (RHC, also called "Swan" catheter). Echo is a test that uses ultrasound to get pictures of your heart through an ultrasound probe that is placed on your chest or upper abdomen. RHC is a procedure where a catheter is inserted into your heart through a large vein (in your neck or groin), and the pressures within your heart are measured directly. This study will show us if echo measurements can be used reliability in patients in the future without having to do invasive catheterization. Patients undergoing both echo and RHC, as determined by their doctor, while in the hospital as part of standard medical care will be enrolled in this study. There is no additional testing that will be done as part of this study. 

Study Details

Inclusion Criteria

  • At least 18 years of age
  • Undergoing both transthoracic echocardiogram and right heart catheterization within 4 hours of each other

Exclusion Criteria

  • History of complex congenital heart disease
  • Mechanical ventilation
  • Inability to provide informed consent

Study Requirements

If you decide to participate in this study, you will undergo echo and RHC measurements as part of standard clinical are, as determined by your doctors. There is no specific order in which these two tests will be completed. There is no additional testing that is required as part of this study. Your participation in the study will last for 24 hours at most due to possible scheduling constraints.
