diastolic filling pattern
The characteristic pattern of ventricular filling assessed by echocardiographic evaluation of mitral inflow velocities.
Full Definition
Diastolic filling patterns describe the phases of ventricular relaxation and filling as assessed through echocardiographic analysis of transmitral flow velocities and tissue Doppler imaging. Patterns are classified as normal, impaired relaxation (Grade I diastolic dysfunction), pseudonormal (Grade II), or restrictive (Grade III). The E/A ratio, deceleration time, and E/e' ratio are key parameters used to characterize these patterns. Assessment of diastolic filling is crucial for diagnosing heart failure with preserved ejection fraction and determining prognosis in various cardiac conditions.
Usage
Usage note: Include specific grade classification (I-III) when documenting diastolic dysfunction.
