Does pulsed Doppler combined with cross-sectional echocardiography accurately diagnose and evaluate the severity of prosthetic valve dysfunction compared to invasive procedures?
Pulsed Doppler combined with cross-sectional echocardiography provides an accurate non-invasive assessment of prosthetic valve dysfunction, including localization and severity.
Veyrat et al. (1985) conducted an observational in Valvar prosthetic dysfunction (n=103). Pulsed Doppler technique combined with cross-sectional echocardiography vs. Invasive procedures and surgical findings (reference standard) was evaluated on Diagnostic reliability and accuracy in assessing severity, site, and size of prosthetic dysfunction. Pulsed Doppler combined with cross-sectional echocardiography demonstrated a diagnostic reliability of ≥90% and accurately assessed the severity of prosthetic valve dysfunction in 86% of cases.
