Overview
Echocardiography
- Left ventricular mass and/or thickness- The left ventricular mass is difficult to measure with 3-dimensional echocardiography . 2-dimensional echocardiography can also be used to assess atleast the wall thickness (wall thickness is increased in both hypertrophy and remodelling).
- Left atrial volume- Highly reliable and best measured using 4-chamber and 2-chamber views. It is clinically relevant as this is reflection of the extent of left ventricular remodelling over time. An index of 34 ml/m2 is considered as an independent predictor death, heart failure, atrial fibrillation, and ischemic stroke--12--. Dilated left atrial volume is however not exclusive to diastolic dysfunction. Other conditions like high output states, bradycardia and 4-chamber enlargement, atrial flutter or atrial fibrillation, mitral valve disease and in few cases of athletes. It is vital therefore to differentiate on clinical basis, other echo volumes etc.
