Heart failure left ventricular systolic dysfunction" and "systolic heart failure". HFrEFe is associated with an ejection fraction of less than 40%. 2) Heart failure with preserved ejection fraction (HFpEF). Synonyms no longer recommended include "diastolic heart failure" and "heart failure with normal ejection fraction". HFpEF occurs when the left ventricle contracts normally during systole, but the ventricle is stiff and does not relax normally during diastole, which impairs filling. Heart failure symptoms are traditionally and somewhat arbitrarily divided into "left" and "right" sided, recognizing that the left and right ventricles of the heart supply different portions of the circulation. However, heart failure
Hypoplastic right heart syndrome or epigenetic problems are: stenosis of the aorta and pulmonary trunk, which is a narrowing of the vessels, atrial and/or ventricular septal defect, tricuspid atresia, hypoplastic left and right heart. When you have hypoplastic right or left heart more than one of these problems occur together [5] There is no cure for hypoplastic right heart syndrome. A three-stage surgical procedure is commonly used to treat the condition. The surgeries rearrange the blood flow within the heart and allow the left ventricles to do the work for the underdeveloped right side of the heart. The three surgeries are spread out over
