NCT00760630
First received: September 24, 2008
Last updated: September 3, 2010
Last verified: September 2010
  Purpose

Newly developed diagnostic parameters have potential to differentiate between epicardial disease and microvascular dysfunction with the help of anatomical details and physiological endpoints and can be used in present clinical settings.


Condition Intervention Phase
Coronary Artery Disease
Device: FFR/CFR and IVUS
Phase 0

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Simultaneous Measurements Of Pressure Gradient, Blood Flow and Percentage Area Stenosis Of Coronary Epicardial Lesions To Assess Severity Of Epicardial Stenosis And Myocardial Infarction

Further study details as provided by University of Cincinnati:

Primary Outcome Measures:
  • to detect ischemic heart disease in patients with abnormal stress tests using MPI with SPECT and to determine the presence of significant epicardial stenosis using coronary angiography with simultaneous physiological pressure and flow measurements [ Time Frame: Upon Diagnostic Angiogram and Flow Wire ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To compare novel measurements, Pressure Drop Coefficient (CDP) & Lesion Flow Coefficient (LFC), against measured current parameters called Fractional flow reserve (FFR) & Coronary flow reserve (CFR). [ Time Frame: Upon Diagnostic Angiogram and Flow Wire ] [ Designated as safety issue: No ]

Estimated Enrollment: 76
Study Start Date: December 2009
Estimated Study Completion Date: April 2012
Estimated Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CDP LFC
all patients will have this calculation based upon diagnostic parameters with IVUS and FFR and/or CFR
Device: FFR/CFR and IVUS
All patients with clinical indication for cardiac cath will have FFR and IVUS
Other Name: Volcano FFR and IVUS catheters will be used

Detailed Description:

The pressure drop coefficient (CDP) is a functional index based on hyperemic dp and u measurements. The lesion flow coefficient (LFC) combines the functional index CDP with an atomic measure (percentage area stenosis) as a single parameter.
