Mitral Valve Essay

307 words - 2 pages

he term mitral valve prolapse was coined by J. Michael Criley in 1966 and gained acceptance over the other descriptor of "billowing" of the mitral valve, as first described by John Brereton Barlow. This is why it is also referred to as Barlow’s Syndrome. Mitral valve prolapse, or MVP, is defined as a valvular heart disorder in which one or both mitral valve flaps close incompletely during systole usually producing either a click or murmur and sometimes produces minor mitral regurgitation. ...view middle of the document...

Patients with classic mitral valve prolapse have excess connective tissue that thickens the spongiosa and separates collagen bundles in the fibrosa. This weakens the leaflets and adjacent tissue, resulting in increased leaflet area and elongation of the chordae tendineae.
Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart condition. When signs and symptoms do occur, it's typically because of mitral regurgitation. Mitral valve prolapse symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include arrhythmia, dizziness or lightheadedness, difficulty breathing or shortness of breath, often when lying flat or during physical activity, fatigue, coughing, and chest pain that’s not caused by a heart attack or coronary artery disease. Mitral valve prolapse often runs in families and can be linked to other conditions such as Marfan syndrome, Ehlers-Danlos syndrome, adult polycystic kidney disease, Ebstein’s anomaly, and scoliosis.
Although most people with mitral valve prolapse never have problems, complications can occur. Complications tend to occur in middle-aged or older adults. They may include mitral valve regurgitation, which may or may not be serious depending on the amount of fluid

1467 words - 6 pages brought back to the heart by the four pulmonary veins, which enter the left auricle. When this chamber contracts, blood is forced into the left ventricle and then by ventricular contraction into the aorta. The bicuspid, or mitral, valve prevents the blood from flowing back into the auricle, and the semilunar valves at the beginning of the aorta stop it from flowing back into the ventricle. Similar valves are present in the pulmonary artery. &nbsp

As it allows blood to leave the ventricle, out we go into the ascending aorta, taking us full circle into systemic circulation (“Basic venous

Physiology Essay

1778 words - 8 pages ventricles relax and the ventricular pressure continues to decrease. There are 2 heart sounds during the cardiac cycle: S1 and S2. S1 is made when the AV valves close. Then systole (ventricular contraction) occurs. After systole, S2 is made by the semilunar valves closing. After S2 diastole (ventricular relaxation) occurs. Mitral stenosis is when the mitral valve closes properly but only opens narrowly. Because the opening is narrow, blood cannot
