The superior transseptal approach provides excellent exposure for mitral valve reconstruction. For atrial fibrillation, cryoablation is less invasive, simpler, and safer than the Cox maze operation. Combining the superior transseptal approach and cryoablation for mitral valve procedures yields a high recovery rate from atrial fibrillation, similar to that of radiofrequency ablation. Cryoablation-related complications such as thromboembolic events or requirement for a permanent pacemaker were not observed in our consecutive series. Cryoablation is also cost-effective.
