May inform procedural risk in normal atria; leaves open generalizability and requires prospective validation.
Observational (n=42)
TEE-guided transseptal catheterization is associated with a low complication rate (2.2%) in patients with structurally normal atria.
Hahn et al. (1995) conducted an observational in Normal-sized atria requiring radiofrequency ablation of left-sided accessory pathways (n=42). Transesophageal echocardiographically guided atrial transseptal catheterization was evaluated on Cardiac complications. Transesophageal echocardiography-guided atrial transseptal catheterization in patients with normal-sized atria had a low complication rate of 2.2% (1 complication in 46 procedures).
