What deceleration time indicates restrictive physiology?

E-wave deceleration time <140ms (or <160ms by some criteria) indicates restrictive diastolic filling, suggesting markedly elevated left atrial pressure and poor prognosis.

What conditions cause restrictive filling?

Restrictive filling occurs in advanced heart failure, cardiac amyloidosis, constrictive pericarditis, and severe hypertensive heart disease with diastolic dysfunction.

How does deceleration time relate to prognosis?

A persistently short deceleration time despite optimal therapy (non-reversible restrictive pattern) carries significantly worse prognosis than reversible restriction that responds to diuresis.

Deceleration Time Restrictive Filling <140ms

Identify restrictive diastolic filling pattern by E-wave deceleration time <140ms on Doppler echocardiography, indicating elevated filling pressures and adverse prognosis.
