Damped and Ventricularized Coronary Pressure Waveforms

10/23/2017

Lloyd W. Klein , MD;

Divya Korpu , MD;

Although the terms ventricularization and damping are commonly used in the cath lab and are widely recognized as indicating possible flow limitation due to catheter position, their hemodynamic origins and mechanism have not been well studied....

Although the terms...

A Novel Simple Technique Using Hyperemia to Enhance Pressure Gradient Measurement of the Lower Extremity During Peripheral Intervention

08/29/2015

Bruce Gray , DO;

Issam Koleilat , MD;

Pressure-wire gradient detection with and without provocative hyperemia testing using this novel approach may prove to be a useful adjunct in the diagnosis and treatment of lower-extremity occlusive disease.

Pressure-wire gradient detection...

Thorsten Reffelmann , MD;

Stephan B. Felix , MD;

Markus Lindner ;

Klaus Empen , MD;

Currently, many methods for quantitation of coronary collateral function are based on intracoronary pressure measurements distal of an occluded balloon, which do not fully account for the dynamic nature of collateral flow. Therefore, a...
