2. Fig 1
View inside left atrium. Incision through the interatrial groove (Waterston) and stay sutures to expose the left atrium. Blue lines depict the endocardial radiofrequency ablation lines. Ablation lines (O) are also performed from the ablation line isolating the left pulmonary veins (LPV) to the base of the excised and resutured left atrial appendage (LAA) amputation site and to the posterior mitral valve (MV) annulus. (p = isolation of the coronary sinus from the posterior left atrial wall; RPV = right pulmonary veins.)

3. Fig 2
View inside right atrium. Bicaval cannulation. Blue lines depict the endocardial radiofrequency ablation lines. The isthmus ablation (F) runs from the inferior caval vein (IVC), across the interatrial septum, up to the caudal aspect of the coronary sinus (CS) ostium and over to the posterior tricuspid valve (TV) annulus. (FO = foramen ovale; RAA = excised and resutured right atrial appendage; SVC = superior vena cava.)
