Figure 1 : 

Three-dimensional navigation system reconstruction of the triangle of Koch after Mustard surgery for d-transposition of the great arteries. A. Posterior view showing the relationship between new atrial cavities and vessels. B. Location of the triangle of Koch with sinus ostium positioned in the left side of the atrial baffle, needing left approach for atrioventricular nodal tachycardia ablation. CSO: coronary sinus ostium; H: His bundle location; LAp: left atrial appendage; LV: left ventricle; PVA: pulmonary venous atrium; RV: right ventricle; SVA: systemic venous atrium; SVC: superior vena cava.

Figure 2 : 

Twin atrioventricular node location with three-dimensional navigation system in a patient with congenitally corrected transposition of the great arteries, large ventricular septal defect and pulmonary stenosis. Ventricular activation by each node produces a different ventricular electrocardiogram pattern of activation. CS: coronary sinus; LA: left atrium; RA: right atrium; SVC: superior vena cava.

Catheter ablation of intra-atrial reentrant tachycardias after Fontan surgery with atriopulmonary connexion for tricuspid atresia. A. Three-dimensional reconstruction with voltage colour-coded map (scar area in grey, normal voltage area in purple). Ablation spots are noted with red dots with three isthmuses for intra-atrial reentrant tachycardia: 1=cavotricuspid isthmus; 2=cannulation scar with short isthmus; 3=isthmus around the atriopulmonary connection. B. Corresponding 12-lead electrocardiogram for each tachycardia related to the three isthmuses. IVC: inferior vena cava; PA: pulmonary artery; RA: right atrium; SVC: superior vena cava.

Catheter ablation of atrial fibrillation in patient with d-transposition of the great arteries and Senning surgery. Conversion to sinus rhythm during ablation at a fragmented site, near a surgical suture line. A. Cranial view of the posterosuperior baffle suture line and ablation site with three-dimensional system reconstruction. B. Electrograms and electrocardiogram during ablation showing organization then conversion to sinus rhythm. PLV: subpulmonary left ventricle; PVA: pulmonary venous atrium; SRV: systemic right ventricle; SVC: superior vena cava.
