Occasionally severe aortic insufficiency necessitates urgent aortic valve replacement. We reviewed our experience with the Ross\u2013Konno procedure in patients &amp;lt;1\u2009year.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>Between October 2013 and May 2020, 36 patients underwent balloon (34) or surgical (2) aortic valvuloplasty for aortic stenosis. Six patients subsequently underwent a Ross\u2013Konno procedure. The median age at operation was 55 (27\u2013116) days and weight was 4.25 (2.5\u201312) kg. All patients were in severe cardiac failure and had a small aortic annulus with Z-score \u22123.1 (\u22121 to \u22124.4).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>There were no early or late deaths. At the latest follow-up at 39 (13\u201360) months, ventricular function had improved in all patients and no patient was on anti-failure medication. On echocardiography, there wasno more than trivial aortic regurgitation and no left ventricular outflow tract obstruction. One patient required right ventricle to pulmonary artery conduit replacement and one patient had homograft stenting.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Despite the severe preoperative haemodynamic compromise, the urgent Ross\u2013Konno procedure was associated with excellent operative survival and recovery of ventricular function.
