An unusual coronary pseudo-obstruction image due to competitive blood flow between critical stenosis in proximal LAD and collateral vessels from RCA

Abstract

This case illustrates an unusual coronary pseudo-obstruction due to competitive coronary flows from critical proximal left anterior descending (LAD) coronary artery stenosis and collateral vessels from distal right coronary artery. The flow dynamics of both antegrade and retrograde flows counterbalanced each other at the second diagonal branch level of LAD causing a total pseudo-obstruction image. © 2015 Akadémiai Kiadó, Budapest.
