Transcatheter Lotus valve implantation in a regurgitant SAPIEN 3 valve

Nicolas M. Van Mieghem1*, MD; Ramon Rodriguez-Olivares1, MD; Arie-Pieter Kappetein2, MD, PhD; Peter P. de Jaegere1, MD, PhD

An 88-year-old male underwent a transcatheter aortic valve implantation with a 26 mm Edwards SAPIEN 3 (S3) valve (Edwards Lifesciences Inc., Irvine, CA, USA) with mild residual paravalvular regurgitation (PAR) after post-dilatation with a 26 mm balloon (Moving image 1). The upper row of Figure 1 illustrates the S3 positioning during expansion (left) with mild PAR by transoesophageal echocardiography (middle) and contrast angiography (right). Transthoracic echocardiography at follow-up (second row) revealed severe PAR (Moving image 2). The pathophysiology of this deterioration to severe PAR is uncertain. S3 sizing and positioning seemed adequate and recoil was excluded. Damage to the S3 integrity by post-dilatation cannot be ruled out. A transcatheter valve-in-S3 implantation with a 27 mm Lotus™ valve (Boston Scientific, Marlborough, MA, USA) followed. The third row displays the Lotus positioning within the S3 (left) and the final result (right) with trivial PAR (middle) (Moving image 3). The bottom row illustrates the mid portion of the frame derived from rotational angiography, confirming identical S3 area at the end of the index procedure and prior to Lotus implantation two months later (no recoil). Note the significant increase in area after Lotus implantation. The Lotus valve is mechanically deployed with high radial force and an adaptive seal. It is completely repositionable and retrievable even after full expansion. These intrinsic features may help optimise transcatheter valve-in-valve procedures.
