The no-flow phenomenon during diagnostic coronary angiography

Definite conclusions for the reason of the no-flow phenomenon are not possible at present, despite multiple different theories that could explain it. What is important from the clinical standpoint is that, although rare, it is a potentially life-threatening condition during diagnostic coronary angiography that should be recognized and aggressively treated. We consider the present report as the first one, to our knowledge, that describes this angiographic entity, and how prompt recognition and adequate management prevents certain death in this population.
