Biventricular ICD implantation succeeds in a patient with mesocardia and ccTGA.
Case Report (n=1)
Biventricular ICD implantation is feasible in patients with complex congenital heart disease, including congenitally corrected transposition and left-sided superior vena cava, despite anatomical and sensing challenges.
May inform individualized device strategies in rare CHD; hypothesis-generating and should not yet alter practice.
An increasing number of patients with congenital heart disease are surviving into adulthood and some have indications for device therapy. Complex anatomical abnormalities may hinder the operator and require the adaptation of standard implantation techniques. We present the first report of successful biventricular ICD implantation in a patient with mesocardia, congenitally corrected transposition of the great arteries, pulmonary atresia, and a left superior vena cava draining into the coronary sinus. This case posed challenges in lead placement due to both complex anatomy and the risk of inappropriate device therapies secondary to far-field oversensing.

Rogers et al. (2008) conducted a case report in Congenitally corrected transposition of the great arteries, pulmonary atresia, left superior vena cava, mesocardia (n=1). Biventricular ICD implantation was evaluated on Successful biventricular ICD implantation. Successful biventricular ICD implantation was achieved in a patient with complex congenital heart disease including mesocardia and congenitally corrected transposition of the great arteries.
