• valvular disease
  • Total content of unesterified fatty acids and activity of ATPases/latent, stimulated by Mg2+, 2,4-DNP, Mg2+ and 2,4-DNP/were studied in heart and liver mitochondria of rabbits with decompensated mitral valvular disease. (msk.ru)
  • Valve failure or dysfunction can result in diminished heart functionality, though the particular consequences are dependent on the type and severity of valvular disease. (wikipedia.org)
  • rheumatic heart d
  • These conditions occur largely as a consequence of aging, but may also be the result of congenital (inborn) abnormalities or specific disease or physiologic processes including rheumatic heart disease and pregnancy. (wikipedia.org)
  • systolic
  • Heart murmurs are most frequently categorized by timing, into systolic heart murmurs and diastolic heart murmurs, differing in the part of the heartbeat on which they can be heard. (wikipedia.org)
  • diastolic
  • Since sarcomere length cannot be determined in the intact heart, other indices of preload such as ventricular end-diastolic volume or pressure are used. (wikipedia.org)
  • This amount of blood is known as the end diastolic volume (EDV), and the mitral valve closes at the end of atrial contraction to prevent a reversal of blood flow. (wikipedia.org)
  • complications
  • Early vascular complications of intraaortic balloon counterpulsation in patients undergoing open heart surgery. (biomedsearch.com)
  • Patients with mechanical heart valves are required to take blood thinners for the rest of their lives, which presents a risk of bleeding complications. (wikipedia.org)
  • tissue
  • Finally, artificial tissue valves will wear out - on average lasting between 10 and 15 years, requiring further surgery at an advanced age. (wikipedia.org)
  • Anatomically, the valves are part of the dense connective tissue of the heart known as the cardiac skeleton and are responsible for the regulation of blood flow through the heart and great vessels. (wikipedia.org)
  • This is because blockage of one coronary artery generally results in death of the heart tissue due to lack of sufficient blood supply from the other branch. (wikipedia.org)
  • posterior
  • The anterior cusp covers approximately two-thirds of the valve (imagine a crescent moon within the circle, where the crescent represents the posterior cusp). (wikipedia.org)
  • On the posterior surface of the heart, the right coronary artery gives rise to the posterior interventricular artery, also known as the posterior descending artery. (wikipedia.org)
  • It runs along the posterior portion of the interventricular sulcus toward the apex of the heart, giving rise to branches that supply the interventricular septum and portions of both ventricles. (wikipedia.org)
  • regurgitant
  • Color Doppler 3D studies have shown that 2D methods generally underestimate mitral regurgitant volume. (clinicaltrials.gov)
  • Although RT3DE measurements have been shown to correlate well with CMR measures of LV volumes, using a 3D volumetric method to calculate mitral regurgitant volumes has not been well studied. (clinicaltrials.gov)
  • We will also compare RT3DE and CMR measures of mitral regurgitant volume. (clinicaltrials.gov)
  • The percentage of blood that regurgitates back through the aortic valve due to AI is known as the regurgitant fraction. (wikipedia.org)
  • backflow
  • These two arteries receive blood from the ventricles and their semilunar valves permit blood to be forced into the arteries, and prevent backflow from the arteries into the ventricles. (wikipedia.org)
  • Chordae
  • They are anchored to the walls of the ventricles by chordae tendineae, which prevent the valves from inverting. (wikipedia.org)
