STS/ACC TVT v3 Education-Sequence# 13700

Sequence# 13700 - Low Flow (Video 1:01)

Video Transcription

Video Summary

The video discusses a new data element called Low Flow in the TAVR module. It is a child field of aortic stenosis and is coded when aortic stenosis is present and the echo result for AV mean gradient is less than 40 mmHg. Low Flow is coded when the stroke volume index is less than 35 mL per square meter. If AV mean gradient or Low Flow is not documented, sequence 13700 is left blank and sequence 13701 is coded as Low Flow not documented. This data element is added to the dataset for evaluation of future appropriate use criteria for transcatheter aortic valve procedures.
