Postural Changes During Right Heart Catheterization
Assessing the Influence of Postural Changes During Right Heart Catheterization for the Evaluation of Pulmonary Hypertension
Study Overview
Status
Intervention / Treatment
Detailed Description
The investigators also plan a prospective study of patients referred for pulmonary artery catheterization at the UNC cardiac catheterization lab for evaluation of known or suspected pulmonary hypertension. The purpose of this portion of the study is to evaluate the degree to which digital reading of pulmonary artery pressure (PAP) and pulmonary capillary wedge pressure (PCWP) impact the diagnosis and classification of pulmonary hypertension specifically in patients being evaluated for pulmonary hypertension while being tested in the supine, sitting and standing positions.
The investigators will identify 60 patients referred for right heart catheterization to evaluate known or suspected pulmonary hypertension. Patients will have right heart catheterization performed by the clinician that was planning on performing the procedure and a pulmonary hypertension specialist in the Division of Pulmonary and Critical Care Medicine or Division of Cardiology. After informed consent is obtained, the subject will be prepped and draped per protocol in the UNC Cath lab. Their internal jugular vein will be visualized by ultrasound and accessed with a pulmonary artery catheter using standard procedure which also uses fluoroscopy to ensure correct placement of the catheter. Once pressure measurements are obtained from the cardiac chambers and pulmonary arteries, the catheter will be secured into place with tegaderm to allow for mobilization of the patient. The patient will then be asked to sit up on the side of the cath table and the pressure transducer will be re-calibrated to be at the level of the patient's right atrium. Repeat measurements will be obtained of the pulmonary artery and PCWP in this position. After, the patient will be asked to stand up and the pressure transducer once again re-calibrated to estimate the level of the right atrium; new measurements will be obtained in the standing position. Each position will be maintained for 5 minutes before measurements are taken. The supine position measurement will be used for clinical decision making purposes as per usual. The investigators will collect each measurement over at least 10 cardiac cycles and use the mean end-expiratory values to ensure precision.
Once all measurements are obtained, the patient will be asked to return to the supine position. The tegaderm will be released and the catheter removed during sustained expiration maneuver per standard protocol.
No sedation will be administered to the patients.
No further contact will be done with the study subject for the purpose of this research trial.
