Key result
Doppler tissue imaging identified all 15 patients with diastolic heart failure, demonstrating similar diagnostic accuracy to mitral pulse wave Doppler and superiority to the AVPD technique.
Why the study?
Does Doppler tissue imaging (DTI) improve the identification of diastolic dysfunction compared to MPWD and AVPD in patients with heart failure?

Supports DTI as alternative to MPWD for diastolic HF identification; leaves open superiority to AVPD pending validation studies.

Does Doppler tissue imaging (DTI) improve the identification of diastolic dysfunction compared to MPWD and AVPD in patients with heart failure?
Regional DTI has similar accuracy as MPWD in identifying diastolic heart failure patients and is superior to the AVPD technique.
Jarnert et al. (2000) conducted an observational in Congestive Heart Failure (n=45). Doppler tissue imaging (DTI) vs. Mitral pulse wave Doppler (MPWD) and atrio-ventricular plane displacement (AVPD) was evaluated on Identification of patients with diastolic heart failure. Doppler tissue imaging identified all 15 patients with diastolic heart failure, demonstrating similar diagnostic accuracy to mitral pulse wave Doppler and superiority to the AVPD technique.
