Key result
Transseptal left heart catheterization in 450 cases resulted in 0 mortalities and only 3 cases of accidental aortic puncture.
Why the study?
Is transseptal left heart catheterization safe and feasible?
Observational (n=450)
Is transseptal left heart catheterization safe and feasible?
Transseptal left heart catheterization is a safe procedure with a low rate of significant complications.
Supports low-risk profile in experienced hands; leaves open prospective validation in modern practice.
Experiences with 450 transseptal left heart catheterizations are reviewed. There were no mortalities in this series, and the only significant complication was accidental puncture of the aorta in three patients. The equipment and technic employed in the current method, by which a radiopaque catheter of large caliber is introduced into the left ventricle, are described in detail. The advantages of this modification are outlined.

Brockenbrough et al. (1962) conducted an observational in Patients requiring left heart catheterization (n=450). Transseptal left heart catheterization was evaluated on Mortality and significant complications. Transseptal left heart catheterization in 450 cases resulted in 0 mortalities and only 3 cases of accidental aortic puncture.
