Does real-time three-dimensional transoesophageal echocardiography guidance improve the feasibility and safety of transseptal puncture in patients undergoing atrial fibrillation ablation?
Real-time 3D TEE is a feasible and safe tool for guiding transseptal puncture during AF ablation, allowing for direct visualization of the fossa ovalis and single-attempt access.
