An interventional study of CD Leycom/Millar Instruments conductance catheter in Constrictive Pericarditis, sponsored by Mayo Clinic. Withdrawn at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2016-11-04.
Sponsored by Mayo Clinic · Not applicable, Interventional, and Diagnostic
Until now, diagnosis of constriction was based on pressure changes of ventricle by conventional pressure-wide hemodynamic evaluation but not on ventricular volume change. This study will provide answers to persisting questions about volume changes during respiration in patients with constrictive pericarditis by directly measuring both right and left ventricular volume.
Subjects referred for right and left heart catheterization will be eligible.
Changes in pressure-volume relationships will be compared to changes in LV and RV systolic pressure during respiration.
Device: CD Leycom/Millar Instruments conductance catheter
Conductance catheter-Pressure volume relationship
Presence of constrictive pericarditis
Time frame: 1 hour
