Comparison of Results of Transcatheter Aortic Valve Implantation in Patients With Severely Stenotic Bicuspid Versus Tricuspid or Non bicuspid Valves

There have been some concerns about outcomes of TAVI in patients with bicuspid aortic valves (BAV). In this retrospective study, outcomes after TAVI in 21 patients with BAVs were compared with those in 447 patients with tricuspid aortic valves (TAV). Device success was lower and 30-day mortality was higher in BAV patients. There was no significant difference between groups in terms of 30-day composite safety end point, postprocedural aortic regurgitation or in 12-month cardiovascular mortality.
