All trials for Constrictive Pericarditis All trials of CD Leycom/Millar Instruments conductance catheter
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.
| Arm | Type | Interventions | Description |
|---|---|---|---|
| Pressure-volume relationship | Experimental | Device: CD Leycom/Millar Instruments conductance catheter | Changes in pressure-volume relationships will be compared to changes in LV and RV systolic pressure during respiration. |
Sex: All, ages: 18 Years to any
Subjects referred for right and left heart catheterization will be eligible.
