Echocardiographic Evaluation of Left Ventricular Diastolic Function in Healthy Neonates

Volume 1, Oct 2012

S R Mittal, MD, DM, Ajmer, Rajasthan, India.

Background: There is scanty literature on echocardiographic evaluation of left ventricular diastolic functions in healthy neonates.

Methods and Results: Detailed echocardiographic evaluation of left ventricular diastolic functions was performed in 18 healthy neonates. Mitral valve diastolic movement on M-mode echocardiography and pulsed Doppler parameters of mitral flow showed normal pattern as seen in adults. Velocity of propagation, pulmonary vein flow pattern and tissue Doppler imaging of medial and lateral mitral annulus showed diminished compliance pattern as compared to older children and adults.

Conclusions: Less compliant pattern of left ventricle is normal in healthy neonates (J Clin Prev Cardiol 2012;1(4):161-6)
Key Words: Diastolic function; echocardiography; left ventricle; neonates; tissue Doppler imaging.
