Urgent Transcatheter Aortic Valve Implantation in Patients With Severe Aortic Stenosis and Acute Heart Failure: Procedural and 30-Day Outcomes.

Background: 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.
