title: Interventional physiology. Part XVIII: Influence of intra-aortic balloon counterpulsation and collateral flow reversal during multivessel angioplasty.
abstract: Flow velocity changes during multivessel angioplasty suggests that collateral flow has an important role in determining safety and ischemic threshold during these procedures. The physiology of collateral flow with and without intra-aortic balloon pumping has been demonstrated in this individual and provides insight into the mechanisms of reduced ischemia during high-risk coronary interventions.
