New Methods to Diagnose Constrictive Pericarditis

Mayo Clinic

Status: Withdrawn

Conditions: Constrictive Pericarditis

Treatments: Device: CD Leycom/Millar Instruments conductance catheter

Study type: Interventional

Funder types: Other

Identifiers

NCT02027350

13-008074

Details and patient eligibility

About

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.

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

Subjects referred for right and left heart catheterization will be eligible.

Trial design

Primary purpose: Diagnostic

Allocation: N/A

Interventional model: Single Group Assignment

Masking: None (Open label)

Pressure-volume relationship

Experimental group

Description:

Changes in pressure-volume relationships will be compared to changes in LV and RV systolic pressure during respiration.
