This case study describes myocardial ischemia and stunning after the topical application of phenylephrine-soaked pledgers (0.25%) in a 63-year- old female undergoing elective endoscopic sinus surgery. The patient had no previous history of cardiovascular disease or illicit drug use. Transient myocardial ischemia was associated with acute hypertension, chest pain, and S-T segment changes 4 minutes after pledget placement. Angiography revealed normal coronary blood flow and severe left ventricular systolic and diastolic dysfunction. Follow-up echo-cardiography demonstrated improved left ventricular function within 1 week and total resolution of dysfunction by 4 weeks after ischemia.
