What does hypertrophic cardiomyopathy look like on Echo?

Mid-systolic notching, coarse systolic fluttering of the aortic valve, and fibrotic septal changes at the level of leaflet-septal contact are related echocardiographic features in obstructive HCM.

How do you confirm a HOCM?

An echocardiogram is commonly used to diagnose hypertrophic cardiomyopathy. This test uses sound waves (ultrasound) to see if your heart’s muscle is abnormally thick. It also shows how well your heart’s chambers and valves are pumping blood.

How does echo measure PDA?

The echocardiography can be used to assess the size of PDA by measuring transductal diameter, interrogate shunt direction, and velocity of blood flow across the ductus arteriosus can be measured by using Doppler technique.

Does echocardiogram show hypertrophic cardiomyopathy?

Abstract. Hypertrophic cardiomyopathy (HCM) is diagnosed on the basis of left ventricular (LV) hypertrophy for which there is insufficient explanation (e.g. mild hypertension or mild aortic stenosis with marked hypertrophy). Echocardiography is an invaluable tool in the diagnosis and follow-up of patients with HCM.

What are the echocardiography findings in HOCM?

Echo findings in HOCM – IVS hypertrophy SAM – mechanism is venturi effect and drag forces within LVOT LV and/or RV hypertrophy – asymmetric usually LVOT Obstruction Diastolic dysfunction LV end diastolic pressure – elevated Pressure gradient across LVOT with dagger shaped continuous wave doppler Decreased LV cavity during systole

When to have an echocardiographic evaluation of PDA?

As clinical signs of PDA are not sensitive or specific enough, all extremely preterm infants at risk of developing PDA should undergo echocardiography. The main goal of the present review is to define and develop the different steps in echocardiographic evaluation of PDA in the preterm infant.

How is the colour Doppler flow mapping done in HOCM?

Initially the apical 5C view is obtained and then the colour Doppler flow mapping (CFM) is done to locate the flow in LVOT. Continuous wave (CW) Doppler cursor is then aligned along the LVOT colour jet of HOCM.

When to use over detection in hypertrophic cardiomyopathy?

Over detection (false-positive diagnosis of hypertrophic cardiomyopathy) In this setting, the septal/posterior wall ratio may exceed 1.5 simply because the septum is mildly hypertrophied and the posterior wall is thinned as a result of the prior infarct. Other forms of hypertrophy may mimic HCM and are described later.
