What are the symptoms of right-sided heart failure? The accumulation of blood in the lungs forces the right ventricle to be overworked and ultimately fail. Right-sided heart failure (right ventricular or RV heart failure) can be caused by issues like lung disease, but most often it is the result of left-sided heart failure. What are the symptoms of left-sided heart failure? As a result, blood backs up into the lungs. This is either because the ventricle can’t exert sufficient force to move the blood or because the ventricle can’t relax properly between beats and allow itself to fill with blood. In this condition, the left ventricle is unable to pump blood out to the body efficiently. Left-sided heart failure (sometimes referred to as left ventricular or LV heart failure) is the more common of the two types. Blood moves from the lungs into the left atrium, down to the left ventricle and then out to the body to supply organs and tissues with oxygen and nutrients. From there it moves to the right ventricle, which pumps it to the lungs where it is oxygenated.

Blood returns from the body and enters the right atrium. Each side of the heart has paired upper and lower chambers. The upper chambers are called atria and the lower chambers are called ventricles. To understand these conditions, it is important to know a little about how blood flows through the heart. In right-sided heart failure, the right side of the heart is weakened and results in fluid in your veins, causing swelling in the legs, ankles, and liver. In left-sided heart failure, the left side of the heart is weakened and results in reduced ability for the heart to pump blood into the body. The major difference between left-sided heart failure and right-sided heart failure is in the side of the heart that is weakened. Heart failure can occur in the left side of the heart, the right side of the heart or on both sides. What is the Difference Between Left-Sided Heart Failure and Right-Sided Heart Failure?
