Elective percutaneous coronary intervention performed during contrast-induced hypotension

Area of Science:

• Cardiology
• Interventional Cardiology
• Pharmacology

Background:

• Contrast reactions can cause severe hypotension, typically necessitating emergency treatment and procedure termination.
• Managing contrast-induced hypotension during cardiac procedures presents significant clinical challenges.

Purpose of the Study:

• To assess the feasibility and safety of elective percutaneous coronary intervention (PCI) in patients experiencing contrast-induced hypotension.
• To evaluate the efficacy of vasopressor support in managing severe hypotension during PCI.

Main Methods:

• A case series involving three patients with a history of contrast-induced hypotension.
• Nine elective PCI procedures were performed with continuous blood pressure monitoring and vasopressor administration.
• Management strategies for contrast-induced hypotension during PCI were implemented.

Main Results:

• Successful completion of all planned PCI procedures was achieved despite contrast-induced hypotension.
• Blood pressure was effectively supported using vasopressors, allowing for uninterrupted intervention.
• No major adverse events were reported during or after the procedures.

Conclusions:

• Performing elective PCI during contrast-induced hypotension is feasible and safe with appropriate blood pressure support.
• Vasopressor management is a viable strategy for patients with a history of severe contrast reactions undergoing PCI.
• This approach offers a potential management pathway for complex cases, avoiding procedure abandonment.
