The self\u2010expandable Allegra 23\u2009mm, advanced through the right femoral artery, got stuck at the point of passage between the aortic arch and the prosthetic tube in the ascending aorta. A peripheral balloon was advanced from the left femoral artery and simultaneously inflated at the stalemate point, while pushing the valve toward the implantation site. Following failure with 5\u2009mm and 7\u2009mm balloons, crossing was successful with a 9\u2009mm balloon.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The standard buddy balloon technique involves the use of a single balloon diameter.
