Transseptal left heart catheterization has been performed as an alternative to the retrograde approach since 1958. However, this procedure can result in life-threatening complications, some of which may occur because of insufficient anatomical landmarks. Accordingly, we sought to assess the safety and efficacy of a new transseptal left heart catheterization technique designed for ablation procedures. Specifically, we examined whether electrode catheters could be used as anatomical landmarks, permitting identification of the aortic root and other critical structures.Results: One hundred and eight consecutive patients underwent transseptal left heart catheterization under biplane fluoroscopy during catheter ablation. Electrode catheters positioned in the right atrial appendage, His bundle region, and coronary sinus were used as anatomical landmarks to guide the transseptal unit to the fossa ovalis. The angles of the right anterior and left anterior oblique projections were selected in each patient based on the orientation of the His bundle and coronary sinus catheters. Transseptal left heart catheterization was successfully performed in all patients without complications. In contrast to previous reports, the direction of the needle at the successful puncture site in the last 96 patients varied substantially: 2 o'clock in 13 patients (13 %); 3 o'clock in 43 patients (45 %); and 4 o'clock in 40 patients (42 %).Conclusion: The use of electrode catheters as anatomical landmarks and biplane fluoroscopy facilitates transseptal catheterization. This approach can be used safely during catheter ablation procedures.
