Right Heart Catheterisation with Dobutamine Stress Test for Evaluation of Right Ventricular Outflow Tract Obstruction 30 Years After Surgical Repair of Tetralogy of Fallot

Abstract

Right ventricular outflow tract obstruction was suspected in a 32-year-old man with repaired tetralogy of Fallot and borderline indications for surgical. Right heart catheterisation with a dobutamine stress test was useful in assessing the dynamics and severity of right ventricular outflow tract obstruction and in determining the treatment strategy.
