This analysis observes hemodynamic fluctuations during chronic total occlusion interventions, suggesting careful monitoring is necessary.
Given the complexity of the procedure, chronic total occlusion (CTO) intervention is often associated with hemodynamic fluctuations. In such cases, it is necessary to ascertain potential causes involving the target vessel, the donor vessel, and non-coronary factors promptly. In addition, the relative hypoperfusion of the target vessel caused by immediate antegrade and retrograde competitive blood flow upon guidewire crossing and establishment of the procedural trajectory is also a problem worthy of consideration.
