Criteria for Referral for AVR, TAVI, and BAV

SAVR

  1. Severe, symptomatic AS

  2. Open heart surgery for another indication AND moderate to severe AS

  3. Severe AS AND LV EF< 50%.
TAVI

  1. High-risk or prohibitive risk surgical patients with severe, symptomatic, trileaflet AS.

  2. Severe, symptomatic AS with STS score ≥ 8, as an alternative to SAVR.*

  3. Severe, symptomatic AS with anatomy precluding SAVR (i.e. radiation to chest, porcelain aorta)

  4. Severe, symptomatic AS with prohibitive surgical risk (an estimated 50% or greater risk of mortality at 30 days due to significant comorbid conditions**)
BAV

  1. Extreme risk patients as a bridge to SAVR or TAVI.

  2. Palliative therapy for short to intermediate term symptomatic improvement.

(LV = left ventricular, EF = ejection fraction)

*

STS score based on referral criteria for partner trials – initially STS ≥ 10, it was later decreased to ≥8.

**

i.e. those comorbid conditions associated with increased mortality with SAVR (liver disease, significant COPD, pulmonary hypertension, etc.)
