title: Urgent Transcatheter Aortic Valve Implantation in Patients With Severe Aortic Stenosis and Acute Heart Failure: Procedural and 30-Day Outcomes.
abstract: Transcatheter aortic valve implantation (TAVI) is recommended for patients with severe symptomatic aortic stenosis (AS) who are at prohibitive/high risk for surgical aortic valve replacement (SAVR). Patients with severe AS may experience acute decompensated heart failure (HF) that is resistant to medical therapy. We report our TAVI experience in treating patients with unstable AS who require urgent intervention for their aortic valve disease.
  
  
  
  Patients were restrictively included in the urgent TAVI registry if they were admitted with acute refractory and persistent HF despite medical therapy and had TAVI performed during the same hospital stay. All others were included in the elective TAVI group.
  
  
  
  Between November 2008 and April 2015, 410 consecutive patients underwent TAVI at our centre-27 (6.6%) urgently. Patients operated on urgently were more likely to be frail and carry higher SAVR mortality risk based on The Society of Thoracic Surgeons Predicted Risk of Mortality/logistic EuroSCORE (LES) measures. Pulmonary edema was the most common clinical presentation. Preprocedural assessment used fewer imaging modalities, yet implantation success remained high and reached 96.3% using an additional valve (valve-within-valve) required in 3 patients, with no difference in periprocedural complications according to the Valve Academic Research Consortium-2 definitions. Although 30-day functional capacity was reduced, patients had similar 30-day mortality and major adverse cardiovascular event rates compared with patients who underwent elective TAVI.
  
  
  
  Short-term outcome after urgent TAVI appears to be reasonable. For patients with severe AS who experience acute decompensated HF that is recalcitrant to optimal medical therapy and who are at high risk with SAVR, urgent TAVI may be a viable treatment strategy. Larger prospective studies and data on long-term outcomes are needed.
