Sudden death risk in congenitally corrected transposition with ventricular dysfunction: Patient case submitted by Matthias Greutmann, MD, FESC

Abstract

1. ACHD patients with systemic ventricular failure and a narrow QRS are not suitable candidates for biventricular pacing. 2. If biventricular pacing leads to poor response or clinical worsening, it is better to turn off pacing (if possible) and leave the patient with their native QRS complex. 3. Patients with severe forms of CHD and severe systemic ventricular failure need to be considered for ICD implantation.
