title: Transapical transcatheter aortic valve implantation in a complex aortic surgical patient: A case involving the youngest valve-in-valve implantation with a 29 mm transcather valve.
abstract: The present article reports a case involving a 29-year-old man who developed severe cardiac failure (New York Heart Association class IV). He had a complex surgical history, beginning with the repair of an anterior sinus of Valsalva aneurysm and closure of a ventricular septal defect at eight months of age. His residual Valsalva aneurysm and mixed aortic valve disease necessitated mechanical aortic valve replacement at 14 years of age. One year later, he developed coagulase-negative staphylococcal prosthetic valve infective endocarditis, necessitating an additional replacement of his valve with a pulmonary homograft. Subsequent follow-up revealed a dilated ascending aorta (6 cm) and increased regurgitation through his homograft, with significant dilation of the left ventricle. At 20 years of age, he underwent excision of the aneurysmal ascending aorta and arch of the aorta, and the aortic valve was replaced with a 29 mm bioprosthetic valve. This proved satisfactory for nine years until he presented at Guy's and St Thomas' National Health Services Foundation Trust (London, United Kingdom) with severe aortic regurgitation. His logistic EuroScore was 5.9 and Parsonnet score was 17 but, due to extensive previous surgery, he was considered and accepted for transcatheter aortic valve implantation. A 29 mm Edwards Sapien valve (Edwards Lifesciences, USA) was successfully implanted using a valve-in-valve procedure. The patient remained well and symptom free at early follow-up. Technical aspects of this complex adult congenital case that, to the authors' knowledge is the youngest case of transcatheter aortic valve implantation and the first 29 mm valve-in-valve procedure, are discussed.
