Purpose:
To analyse the transseptal catheterization technique, its indications and possible complications.
Methods:
The transseptal catheterization has been undertaken in 233 patients, 202 children (aged 0.1 to 16 years) with congenital heart disease and 31 adults (aged 37 to 73 years) submitted to mitral valvuloplasty. The Mullins technique was employed to access left heart chambers.
Results:
In the pediatric group, the indications for transseptal catheterization were coarctation of the aorta and valvular or subvalvular aortic stenosis. By this technique, multiple diagnostic analysis and therapeutic procedures, such as blade atrioseptostomy and mitral valvuloplasty, became available. Among the complications in the 2 groups, pericardial perforation was the most frequent, depending on the laboratory practice with this technique.
Conclusion:
The transseptal cardiac catheterization is a safe and effective technique to investigate hemodynamic data in several congenital heart diseases and is essential to many therapeutic procedures. The technique has a low incidence of complications when employed by experienced teams.
