Early outcomes of the suprasternal transcatheter aortic valve replacement technique

An Updated Comprehensive Review of Existing Transcatheter Aortic Valve Replacement Access

For the past 20 years, transcatheter aortic valve replacement (TAVR) has been the treatment of choice for symptomatic aortic stenosis. The transfemoral (TF) access is considered the gold standard approach for TAVR. However, TF-TAVR cannot be performed in some patients; thus, alternative accesses are required. Our review paper generalises the TAVR accesses currently available, including the transapical, transaortic, trans-subclavian/axillary, transcarotid, transcaval, and suprasternal approaches. Their advantages and disadvantages have been analysed. Since there is no standard recommendation for an alternative approach, access selection depends on the expertise of the local cardiac team, patient characteristics, and access properties. Each TAVR centre is recommended to master a minimum of one non-TF access alternative. Of note, more evidence is required to delve into the clinical outcomes of each approach, at both early and long-term (Figure 1).

Suprasternal transcatheter aortic valve replacement: Modified trocar-free technique

BACKGROUND AND AIM OF STUDY

Transcatheter aortic valve replacement is established as the standard treatment for severe aortic stenosis. Many approaches have been described, including the suprasternal technique, an alternative for patients with unsuitable femoral arteries. We now describe a trocar-free technique for the Suprasternal approach.

METHODS AND RESULTS

Under endotracheal anesthesia, an incision is made above the manubrium and dissection is carried down to the innominate artery with adequate exposure for cannulation. Access site is closed with purse-string suture. The Suprasternal approach has relatively few contraindications.

CONCLUSION

Our trocar-free technique is a safe and easily reproducible technique for TAVRs in patients with poor femoral access.
