Hypotension During Chronic Total Occlusion Recanalization

Key Points

To understand the causes of hypotension during chronic total occlusion (CTO) interventions and their hemodynamic effects.
Analyzed hemodynamic changes during CTO procedures.
Investigated causes related to target vessels and donor vessels.
Evaluated the impact of blood flow dynamics during guidewire crossing.
Identified significant hemodynamic fluctuations during CTO interventions.
Highlighted the role of competitive blood flow in hypoperfusion.
Suggested the need for timely identification of causes to mitigate hypotension risks.

Abstract

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.
