TCT-374 Novel method to assess both the epicardial and microvascular domain using vascular conductance obtained from intracoronary pressure and flow velocity

Methods Validation of this new approach was performed in a total of 403 both obstructive and non-obstructive coronary vessels interrogated with intracoronary Doppler and pressure in 261 patients with stable angina pectoris. Conclusion A comprehensive assessment of the coronary circulation, based on...

Description
Summary:Methods Validation of this new approach was performed in a total of 403 both obstructive and non-obstructive coronary vessels interrogated with intracoronary Doppler and pressure in 261 patients with stable angina pectoris. Conclusion A comprehensive assessment of the coronary circulation, based on separate calculation of epicardial- and microcirculatory conductance, is feasible and provides a clear, coherent depiction of coronary haemodynamics in ischaemic heart disease.
