CRRAC = critical status, renal dysfunction, right atrial pressure, cardiac output
AV = aortic valvuloplasty
Outcome: 30-day mortality following the valvuloplasty
Parameters:
(1) critical status
(2) renal dysfunction (based on serum creatinine)
(3) right atrial pressure prior to the procedure in mm Hg
(4) cardiac output
Critical status:
(1) ventricular tachycardia or fibrillation
(2) aborted sudden death
(3) preoperative ventilation
(4) preoperative inotropic support
(5) intra-aortic balloon counterpulsation
(6) preoperative anuria or oliguria

total score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: based on right atrial pressure
• maximum score: 39 + right atrial pressure
• The higher the score the greater the risk of 30-day mortality.
