CHOICE OF MINISTERNOTOMY
Conventional approach, TF-AVI or TA-AVI, was not desirable AND the ascending aorta was deemed suitable for conventional cannulation
STEP BY STEP PROCEDUREA 5 cm J-shaped upper ministernotomy;
A 8-Fr sheath insertion through a double pledgets reinforced purse string sutures with the Seldinger technique;
Crossing aortic valve with a straight wire supported by a right Judkins catheter;
Insertion of a pre-shaping super stiff guide wire in left ventricle;
Finally the Ascendra 2 transapical delivery system is introduced through the aorta and kept in its upper part.
IDEAL STAIGHT LINE FOR OPTIMAL VALVE RELEASE
• A non-calcified area on the ascending aorta was identified which would allow direction of the sheath in a STRAIGHT LINE to deploy the device, leaving enough space between the Ascendra system and the device itself.

THE DAY AFTER
• RX TORACE
LESSON LEARNED
• Procedural success: adequate technical placement, normal bioproshesis performance and recovery;
• Advantage: overcoming challenging aorto-ileo –femoral-vascular disease, avoid arch crossing and new left ventricular scar;
• The proximity between the puncture site and the native aortic valve allows easier manipulation and delivery of the device, with an IDEAL straight line.
CONCLUSIONS
• Upper ministernotomy represent an additional option for patients who are NOT candidates for TF-AVI and in whom an apical approach may represent a less desirable option (low EF, severe pulmonary disfunction);
• Access to arterial brachiocephalic trunk is also avaible through this incision;
• Controindication for transaortic TAo-AVI approach: porcelain aorta.
