NASA has released an image taken by the Hubble space telescope of a cluster of stars known as NGC-121, in one of our neighboring galaxies. ESA/Hubble/NASA. Saturn's largest and second largest moons, Titan and Rhea, appear to be stacked on top of each other in this true-color scene from NASA's Cassini spacecraft.
An enlarged left ventricle of the heart can be the result of heart muscle disease caused by medication, drugs, alcohol, idiopathic (cause unknown).
Most cases involve both sides of the heart. Right-side heart failure occurs if the heart can't pump enough blood to the lungs to pick up oxygen. Left-side heart failure occurs if the heart can't pump enough oxygen-rich blood to the rest of the body. Right-side heart failure may cause fluid to build up in the feet, ankles, legs, liver, abdomen, and the veins in the neck. Right-side and left-side heart failure also may cause shortness of breath and fatigue (tiredness). The leading causes of heart failure are diseases that damage the heart. Examples include coronary heart disease (CHD), high blood pressure, and diabetes.
