Decreased left ventricular size
What is left ventricular hypoplasia (LVH)?
Left ventricular hypoplasia Is associated with a variety of congenital heart defects, including critical aortic stenosis, unbalanced atrioventricular canal, and total anomalous pulmonary venous connection, and is almost uniformly fatal without surgical or catheter·directed intervention.
When to report the right ventricle as dilated on Echo?
. • report the right ventricle as dilated despite measuring within the normal range, on the basis of a right ventricle appearing significantly larger than the left ventricle. Recommendations for Cardiac Chamber Quantification by Echo in Adults: update from ASE/EACI. JASE 2015;28:1-39 RIGTH VENTRICULAR OUTFLOW TRACT Proximal RVOT Distal RVOT
What causes left ventricular pressure to increase during diastole?
In early diastole, left ventricular pressure reaches its nadir, which is followed by an increase in pressure caused by a combination of forces, such as the viscoelastic forces of the myocardium, pericardial restraint and ventricular interaction (5–7,17,18,20,49,52).
Why is the E velocity low in diastole?
There is a slower decrease in the rate of decrease of left ventricular pressure, and the duration of relaxation is prolonged into mid- or even late diastole. A lower initial driving force across the mitral valve occurs because of this slower rate of ventricular relaxation and results in a low E velocity.

left ventricular wall thickness andmassdecreased, apparently as a result ofthedecreaseoftheleft ventricular preload and also ofthe decrease ofthe afterload, because the systolic blood pressure decreased. Theleft atrial diameter decreased in response to the decreased left ventricular preload andwall hypertrophy.

V1 lead is the best lead to view ventricular activity and differentiate between right and left bundle branch blocks. The only way to view V1 is with a five lead system. Therefore, MCL1 was designed to overcome the inconvenience of a five lead system and provide all the advantages of V1 viewing.

Difficult filling results in systemic venous elevation, which does not fall during inspiration. When both right and left filling pressures reach the level of 15-30 mm Hg, pulmonary venous congestion occurs. Although the myocardium may be intrinsically normal, the insufficient LV filling leads to decreased cardiac output, especially during exercise.

Left ventricular aneurysm. Occurs days to weeks post MI. Begins with infarct expansion, necrosis, removal of debris, replace with scar. Risk factors include large infarcts, uncontrolled hypertension, receiving steroids or NSAIDs. Apical dyskinesis/aneurysm predisposes to thrombus. Can compromise pump function and cause VT.
