New Methods to Diagnose Constrictive Pericarditis
The recruitment status of this trial is unknown because the information has not been verified recently.
|Treatment||cd leycom/millar instruments conductance catheter|
|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.
|Endpoint classification||efficacy study|
|Intervention model||single group assignment|
Changes in pressure-volume relationships will be compared to changes in LV and RV systolic pressure during respiration.
Presence of constrictive pericarditis
time frame: 1 hour
Male or female participants at least 18 years old.
Subjects referred for right and left heart catheterization will be eligible.
|Official title||Pressure-Volume Analysis of Constrictive Pericarditis|
