Redo surgical aortic valve replacement carries substantial morbidity and mortality, particularly in elderly or high\u2010risk patients. Valve\u2010in\u2010valve (ViV) transcatheter aortic valve implantation (TAVI) has become an established alternative, though data on the performance of self\u2010expanding Portico and Navitor valves remain limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively analyzed 47 consecutive patients who underwent ViV TAVI for severe bioprosthetic aortic valve dysfunction between January 2020 and June 2024 at Barts Heart Center. In\u2010hospital and 30\u2010day outcomes were evaluated using Valve Academic Research Consortium 3 criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The median age was 79 years, and 80.9% had small surgical valves (\u2264\u200923\u2009mm). ViV TAVI with Portico or Navitor valves was successful in 46 cases (97.9%), with no in\u2010hospital mortality or need for emergency cardiac surgery. Technical success was achieved in 89.4% of cases; failures were related to two major vascular complications, two valve\u2010related interventions, and one major cardiac structural complication. At 30 days, device success and safety outcomes were favorable, with no deaths or additional major complications. Two patients (4.3%) experienced ischemic stroke, and one (2.8%) required a new permanent pacemaker. Most patients (97.8%) were in NYHA class I\u2013II. Echocardiography confirmed intended valve performance in 87% of cases, with no moderate or severe aortic regurgitation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>ViV TAVI with Portico and Navitor valves is a safe and effective option for failed surgical bioprostheses, including small valves, offering excellent short\u2010term outcomes.
