Aspirin-Exacerbated Respiratory Disease Requiring Desensitization Prior to Planned Percutaneous Catheterization Intervention.

Aspirin-exacerbated respiratory disease (AERD) consists of a triad of asthma, chronic rhinosinusitis with nasal polyposis, and a hypersensitivity reaction to aspirin consisting of nasal congestion and broncho-constriction. This disease presents a conundrum in cardiac patients undergoing percutaneous catheterization intervention (PCI) who might require stent deployment due to the need for aspirin as part of the dual antiplatelet therapy required if a stent is placed. Here, we present the case of a patient who underwent a coronary angiogram showing two-vessel disease but had to undergo aspirin desensitization first before planned PCI as he had a history of severe aspirin allergy in the past.
