| click-murmur syndrome | <syndrome> Mitral valve prolapse (also known as Barlow's syndrome ), the most common heart valve abnormality, affecting 5-10% of the world population. Most patients have no symptoms and require no treatment, but some have fatigue and/or palpitations. The mitral valve prolapse can often be detected by a doctor during examination of the heart and confirmed with an echocardiogram. Patients are usually given antibiotics prior to any procedure which might introduce bacteria into the bloodstream, including dental work and minor surgery, because of an increased risk of infection of the abnormal heart valve.

|---|---|
| mitral murmur | A murmur produced at the mitral valve, either obstructive or regurgitant. (05 Mar 2000) |
| Cole-Cecil murmur | The diastolic murmur of aortic insufficiency when well or predominantly heard in the left axilla. (05 Mar 2000) |
| water wheel murmur | Churning cardiac murmur produced by air embolism to the heart; also heard in pneumohydropericardium. Synonym: water wheel murmur. (05 Mar 2000) |
| pleuropericardial murmur | A pleural friction sound over the pericardial region, synchronous with the heart's action, and simulating a pericardial murmur (rub). (05 Mar 2000) |
| murmur | A finding on physical examination of the heart that can, in some cases, indicate the presence of cardiac disease. Murmurs result from vibrations set up in the bloodstream and the surrounding heart and great vessels as the result of turbulent flow. (27 Sep 1997) |
| continuous murmur | A murmur that is heard without interruption throughout systole and into diastole. (05 Mar 2000) |
| cooing murmur | A murmur, usually of mitral regurgitation, of very high pitch resembling the cooing of a pigeon or a dove. (05 Mar 2000) |
| Coombs murmur | A blubbering apical middiastolic murmur occurring in the acute stage of rheumatic mitral valvulitis and disappearing as the valvulitis subsides. Synonym: Coombs murmur. (05 Mar 2000) |
| musical murmur | A cardiac or vascular murmur having a high-pitched musical character. (05 Mar 2000) |
| crescendo murmur | A murmur that increases in intensity and suddenly ceases; the presystolic murmur of mitral stenosis is a common example. (05 Mar 2000) |
| Cruveilhier-Baumgarten murmur | A venous murmur heard over collateral veins, connecting portal and caval venous systems, on the abdominal wall. See: Cruveilhier-Baumgarten sign. (05 Mar 2000) |
| Hamman's murmur | A crunching precordial sound synchronous with the heart beat; heard in mediastinal emphysema. (05 Mar 2000) |
| presystolic murmur | A murmur heard at the end of ventricular diastole (during atrial systole if in sinus rhythm), usually due to obstruction at one of the atrioventricular orifices. Synonym: atriosystolic murmur, late diastolic murmur. (05 Mar 2000) |
| heart murmur | A finding on physical examination of the heart that can, in some cases, indicate the presence of cardiac disease. Murmurs result from vibrations set up in the bloodstream and the surrounding heart and great vessels as the result of turbulent flow. (27 Sep 1997) |
