Primary angioplasty using a urokinase-coated hydrogel balloon in acute myocardial infarction during pregnancy

A 38-year-old multigravid white female presented at 16 weeks gestation with an acute inferoposterolateral myocardial infarction. Emergent coronary angiography demonstrated a total proximal occlusion of a large dominant left circumflex artery with a filling defect at the site of the occlusion suggestive of thrombus. Primary angioplasty using a urokinase-coated hydrogel balloon resulted in successful recanalization of the vessel with restoration of normal TIMI Grade III flow and, most notably, apparent complete lysis of the intracoronary thrombus. After a subsequently uneventful pregnancy, a healthy baby was delivered.
