The Aortic Valve is a valvular system that bears different high pressure forces. It takes part of a complex structure called Aortic Root. Nowadays, anatomic knowledge has taken a preponderant role, due to the use of the Transcatether Aortic Valve Implant (TAVI). To describe the patient´s characteristics which exclude them of the TAVI for anatomic reasons in cadaveric dissections and transthoracic echocardiograms. A descriptive retrospective analysis of 67 individuals was performed and divided into two groups. Group A: Formalized cadaveric dissections with hypertrofic hearts and aortic sclerosis signs from the Chair A of Anatomy of the University of La Plata (UNLP). Group B: Transthoracic Echocardiograms realized at the San Martín Hospital of La Plata between January 2005 and December 2009. Out of 67 individuals assessed, 17 (25%) had one or more contraindications for TAVI. Five on Group A (36%), and 12 on Group B (23%). The most common anatomic contraindication was the Ascending Aortic diameter less than 30mm and the aortic annulus less than 20mm, following to the RAo-TSVI Angle more than 145° (2 to Group A, and 4 to Group B) and the Septal thickness more than 17mm (no one to Group A, and 3 to Group B). Only just one individual was found with a low implant left coronary artery in the Group A avoiding TAVI. According to this study, the anatomic contraindications to realize TAVI are frequent due to the diagnosis devices available at the moment. The anatomic aortic root knowledge and the aortic valve interindividual variability will allow the improvement of the manufactured devices made in the market. |
