Abstract

Allergy to contrast media is hazardous in patients who need multiple cardiac catheterizations. We describe the case of a 16-year-old boy who presented with fatigue and cyanosis. He had undergone a Fontan operation 14 years previously, after which he developed an allergy to iodinated contrast media. Contrast echocardiograms by manual injection of microbubbles suggested the presence of a venovenous collateral vessel from the brachio-cephalic vein draining into the pulmonary vein. We used intravascular ultrasound as the sole imaging method to identify the target vessel and to guide deployment of an Am-platzer Vascular Plug II. The patient experienced immediate improvement in his systemic saturation. Our experience shows that intravascular ultrasound may be a feasible alternative to standard imaging methods in patients with congenital heart disease who need cardiac interventional procedures and are allergic to contrast media.
