Association of transaortic approach and transoesophageal echocardiography as the primary imaging technique for improved results in transcatheter valve implantation.

OBJECTIVES

The transaortic access has been proposed to perform transcatheter aortic valve implantation in patients with no other available access. We hypothesize that its coupling with transoesophageal echocardiographic guidance may further reduce procedure-related morbidity.

METHODS

Transoesophageal echocardiography was adopted as the primary imaging modality to produce high-resolution images and to guide the deployment of the transcatheter valve. This imaging modality allows continuous visualization not only of the prosthesis and of the delivery system, but also of the surrounding anatomical landmarks (aortic annulus, sinotubular junction and anterior mitral leaflet).

RESULTS

We report an initial series of eight patients, who were treated by a transaortic delivery of the transcatheter valve (SAPIEN Valve, Edwards Lifesciences Inc., Irvine, CA, USA) through an upper mini-sternotomy and guided by transoesophageal echocardiography. The procedure was uneventful in all patients; there were no cases of access site morbidity, periprocedural stroke or renal failure.

CONCLUSIONS

The association of the transaortic route and the transoesophageal echo guidance has the potential to improve the results of transcatheter valve implantation, and deserves further investigation.
