The most common symptom of hypertrophic cardiomyopathy is dyspnoea which occurs in 90% of cases and is due to elevated left ventricular diastolic pressures as a consequence of the diastolic dysfunction.

Assessment of LV Diastolic Function by Echo in SR and AF

All About Cardiovascular System and Disorders

Though there are several parameters for evaluation of left ventricular diastolic function by echocardiography, the most commonly used are the pulsed Doppler mitral E/A ratio and tissue Doppler mitral E/e’ ratio. Doppler interrogation of mitral valve is usually done from the apex through the apical four chamber view.

Here it is 1 and in cases like asymmetric septal hypertrophy or hypertrophic cardiomyopathy, there will be disproportionate thickening of the septum.
