John Michael Criley, MD, FACC, MACP, (born 1931) is Professor Emeritus at the David Geffen School of Medicine at University of California, Los Angeles (UCLA). [1]
He has made a number of pioneering contributions to the field of cardiology and medical education of the physical examination. He was also instrumental in the development of the Los Angeles County Fire Department's Paramedic program in 1969. [2]
He is an authority on cardiac hemodynamics, cardiac auscultation, cardiac catheterization, and valvular heart disease. He served for 25 years as Division Chief at Harbor-UCLA Medical Center in Torrance, California.
In addition, he is also credited with the term mitral valve prolapse, after demonstrating to Dr. Barlow that it was not aneurysm of the mitral leaflet but rather displacement of the leaflet that led to the condition.[ citation needed ]
Emergency! is an American action-adventure medical drama television series jointly produced by Mark VII Limited and Universal Television. Debuting on NBC as a midseason replacement on January 15, 1972, replacing the two short-lived situation comedy series The Partners and The Good Life, it ran for a total of 122 episodes until May 28, 1977, with six additional two-hour television films during the next two years, 1978 and 1979.
The mitral valve, also known as the bicuspid valve or left atrioventricular valve, is one of the four heart valves. It has two cusps or flaps and lies between the left atrium and the left ventricle of the heart. The heart valves are all one-way valves allowing blood flow in just one direction. The mitral valve and the tricuspid valve are known as the atrioventricular valves because they lie between the atria and the ventricles.
Westwood is a commercial and residential neighborhood in the northern central portion of the Westside region of Los Angeles, California. It is the home of the University of California, Los Angeles (UCLA). Bordering the campus on the south is Westwood Village, a major regional district for shopping, dining, movie theaters, and other entertainment.
Mitral valve prolapse (MVP) is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole. It is the primary form of myxomatous degeneration of the valve. There are various types of MVP, broadly classified as classic and nonclassic. In severe cases of classic MVP, complications include mitral regurgitation, infective endocarditis, congestive heart failure, and, in rare circumstances, cardiac arrest.
Mitral stenosis is a valvular heart disease characterized by the narrowing of the opening of the mitral valve of the heart. It is almost always caused by rheumatic valvular heart disease. Normally, the mitral valve is about 5 cm2 during diastole. Any decrease in area below 2 cm2 causes mitral stenosis. Early diagnosis of mitral stenosis in pregnancy is very important as the heart cannot tolerate increased cardiac output demand as in the case of exercise and pregnancy. Atrial fibrillation is a common complication of resulting left atrial enlargement, which can lead to systemic thromboembolic complications such as stroke.
Mitral regurgitation (MR), also known as mitral insufficiency or mitral incompetence, is a form of valvular heart disease in which the mitral valve is insufficient and does not close properly when the heart pumps out blood. It is the abnormal leaking of blood backwards – regurgitation from the left ventricle, through the mitral valve, into the left atrium, when the left ventricle contracts. Mitral regurgitation is the most common form of valvular heart disease.
Franklin David Murphy was an American administrator, educator, and medical doctor. During his life, he served as Chancellor of the University of Kansas (KU) and Chancellor of the University of California, Los Angeles (UCLA).
In cardiology, an Austin Flint murmur is a low-pitched rumbling heart murmur which is best heard at the cardiac apex. It can be a mid-diastolic or presystolic murmur It is associated with severe aortic regurgitation, although the role of this sign in clinical practice has been questioned.
Mitral valve repair is a cardiac surgery procedure performed by cardiac surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, through the pulmonary veins, to the left atrium of the heart. After the left atrium fills with blood, the mitral valve allows blood to flow from the left atrium into the heart's main pumping chamber called the left ventricle. It then closes to keep blood from leaking back into the left atrium or lungs when the ventricle contracts (squeezes) to push blood out to the body. It has two flaps, or leaflets, known as cusps.
Mitral valve replacement is a procedure whereby the diseased mitral valve of a patient's heart is replaced by either a mechanical or tissue (bioprosthetic) valve.
