Overview

May aid non-invasive LVEDP estimation in mitral stenosis; hypothesis-generating and requires prospective validation.

Structured PICO

Can a Doppler echocardiographic prediction model accurately estimate LVEDP in patients with moderate to severe mitral stenosis?

P
Population
33 patients with moderate to severe mitral stenosis (MS) who had indications for left heart catheterisation
I
Intervention
Doppler echocardiographic prediction model (combining left atrium area [LAA], isovolumic relaxation time [IVRT], and annular early diastolic velocity [Ea])
C
Comparator
Invasive measurement of LVEDP during left cardiac catheterisation
O
Outcome
Prediction of LVEDP ≥ 15 mmHgsurrogate

A combination of Doppler echocardiographic variables (LAA, IVRT, and Ea) can non-invasively estimate elevated LVEDP in patients with moderate to severe mitral stenosis.

Limitations

  • Requires further studies to confirm results
