| Austin Flint | <person> Flint, the son and grandson of physicians, was born in Massachusetts and graduated from Harvard Medical School in 1832. He founded the Buffalo Medical College. Austin became associated with Dr. Samuel D. Gross at the University of Louisville. He was a pioneer user and advocator of the binaural stethoscope, and was called the "American Laennec." This internist described a loud presystolic murmur at the cardiac apex in aortic regurgitation now known as the Austin Flint Murmur (1862). He introduced the terms "cavernous" and "broncho-vesicular respiration." His "Principles and Practice of Medicine" published in 1866 was a leading textbook of medicine for many years. Lived: 1812-1886. (18 Nov 1997) |
| Austin Flint murmur | Synonym: Austin Flint phenomenon, Flint's murmur. (05 Mar 2000) |
| Austin Flint phenomenon | The murmur of relative mitral stenosis during significant aortic regurgitation owing to narrowing of the mitral orifice by pressure of the aortic regurgitant flow on the anterior mitral leaflet. Synonym: Austin Flint murmur. (05 Mar 2000) |
| flint | 1. <chemical> A massive, somewhat impure variety of quartz, in colour usually of a gray to brown or nearly black, breaking with a conchoidal fracture and sharp edge. It is very hard, and strikes fire with steel. 2. A piece of flint for striking fire; formerly much used, especially. In the hammers of gun locks. 3. Anything extremely hard, unimpressible, and unyielding, like flint. "A heart of flint." Flint age. An obsolete appliance for lighting the miner at his work, in which flints on a revolving wheel were made to produce a shower of sparks, which gave light, but did not inflame the fire damp. Flint stone, a hard, siliceous stone; a flint. Flint wall, a kind of wall, common in England, on the face of which are exposed the black surfaces of broken flints set in the mortar, with quions of masonry.

| Flint's murmur | A diastolic murmur, similar to that of mitral stenosis, heard best at the cardiac apex in some cases of free aortic insufficiency; it is thought to be caused by the turbulent regurgitating stream from the aorta mixing into the stream simultaneously entering from the left atrium through the mitral valve, causing posterior movement of the anterior leaflet of the mitral valve with transient acceleration of blood flow through the mitral valve. Synonym: Austin Flint murmur. (05 Mar 2000) |
| Flint's syndrome | <syndrome> Acute renal failure occurring in a patient with liver failure. The exact causal relationship in unclear, but those with alcoholic cirrhosis and alcoholic hepatitis are at greatest risk.
