|CHSS Score for Neonatal Critical Aortic Stenosis Calculator
The score is the predicted difference in 5-year survival for a UVR minus a BVR. A positive number favors a UVR; a negative number favors a BVR, with the magnitude of the difference expressed by the number.
For example, a CHSS Score of +10 predicts that 5-year survival is 10% greater for a UVR versus a BVR. A score of -20 predicts that 5-year survival after a BVR is 20% greater than after a UVR.
"Please note, the CHSS on-line AS Calculator survival predictions were previously reported in decimal points rather than % survival. The calculator has now been changed to % Survival. We apologize for any confusion this inadvertent error has caused."
