Abstract

An 88-year-old woman was diagnosed with aortic stenosis and an aortic annulus that was too narrow to perform transcatheter aortic valve implantation. Surgery was performed through a 7-cm right mini-thoracotomy at the fourth intercostal space. A 19-mm aortic valve bioprosthesis was implanted after root enlargement. The fourth intercostal space was a suitable site for aortic root enlargement because of the shorter skin-to-root distance and the detailed exposure of the aortic valve after cutting the aortic wall. This study concluded that minimally-invasive aortic valve replacement following root enlargement can be an option for the treatment of elderly patients with aortic stenosis accompanied by an annulus that is too small to perform transcatheter aortic valve implantation.
