Condition constrictive pericarditis
Treatment cd leycom/millar instruments conductance catheter
Sponsor Mayo Clinic
Start date December 2013
End date November 2015
Trial size 0 participants
Trial identifier NCT02027350, 13-008074


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.

Primary purpose diagnostic
Changes in pressure-volume relationships will be compared to changes in LV and RV systolic pressure during respiration.
cd leycom/millar instruments conductance catheter
