Late dysfunction of the systemic right ventricle in patients with complete transposition of the great arteries after Mustard or Senning procedures and progressive deterioration of the clinical status has been demonstrated. However, evidence-based data on the effective therapy for systemic right ventricular dysfunction in these patients are yet to be defined. Our patient shows an improvement in the right ventricular systolic function, with a reduction in tricuspid regurgitation and a consequent better exercise tolerance after a hybrid approach consisting of an upgrading of a previous transvenous-implanted dual-chamber Implantable Cardiac Defibrillator to biventricular pacing associated with pulmonary artery banding via an anterior thoracotomy.
