Key result
Real-time 3D TEE guides NeoChord procedures more accurately than 2D TEE in degenerative mitral disease.
Why the study?
Transapical off-pump mitral valve intervention with neochord implantation requires accurate echocardiographic guidance, and the added value of 3D real-time transesophageal echocardiography over 2D is important to define.
Does 3D real-time transesophageal echocardiography provide more accurate procedural guidance than 2D echocardiography in patients undergoing the NeoChord procedure?
Does 3D real-time transesophageal echocardiography provide more accurate procedural guidance than 2D echocardiography in patients undergoing the NeoChord procedure?
3D real-time transesophageal echocardiography is mandatory for accurate guidance during the transapical off-pump NeoChord procedure.

3D TEE may aid neochord implantation guidance; leaves open outcome benefit versus 2D alone.
BACKGROUND: Transapical off-pump mitral valve intervention with neochord implantation for degenerative mitral valve disease have been recently introduced in the surgical practice. The procedure is performed under 2D-3D transesophageal echocardiography guidance. METHODS: The use of 3D real-time transesophageal echocardiography provides more accurate information than 2D echocardiography only in all the steps of the procedure. In particular 3D echocardiography is mandatory for preoperative assessment of the morphology of the valve, for correct positioning of the neochord on the diseased segment , for the final tensioning of the chordae and for the final evaluation of the surgical result. RESULT AND CONCLUSION: This article is to outline the technical aspects of the transesophageal echocardiography guidance of the NeoChord procedure showing that the procedure can be performed only with a close and continuous interaction between the anesthesiologist and the cardiac surgeon.

Pittarello et al. (2015) conducted a review in Degenerative mitral valve disease. 3D real-time transesophageal echocardiography vs. 2D echocardiography was evaluated. 3D real-time transesophageal echocardiography provides more accurate information than 2D echocardiography for guiding the NeoChord procedure in degenerative mitral valve disease.
