May support noninvasive Doppler for mitral disc valve area; leaves open prospective confirmation before clinical adoption.
Does non-invasive ultrasound Doppler accurately measure effective valve area in patients with mitral disc valve implants compared to invasive manometric data?
Non-invasive ultrasound Doppler techniques provide effective valve area measurements that correlate well with invasive manometric data in patients with mitral disc valve implants.
Holen et al. (1977) studied this question.
