  2. Mitral valve prolapse - Wikipedia

    en.wikipedia.org/wiki/Mitral_valve_prolapse

    Transesophageal echocardiogram of mitral valve prolapse. Mitral valve prolapse classification. Diagnosis of mitral valve prolapse is based on modern echocardiographic techniques which can pinpoint abnormal leaflet thickening and other related pathology. Echocardiography is the most useful method of diagnosing a prolapsed mitral valve. Two- and ...

    en.wikipedia.org/wiki/Mitral_regurgitation

    Dysfunction of any of these portions of the mitral valve apparatus can cause regurgitation. [citation needed] The most common cause of MR in developed countries is mitral valve prolapse. [10] It is the most common cause of primary mitral regurgitation in the United States, causing about 50% of cases. Myxomatous degeneration of the mitral valve ...

    en.wikipedia.org/wiki/Mitral_valve

    The mitral valve is typically 4 to 6 square centimetres (0.62 to 0.93 sq in) in area and sits in the left heart between the left atrium and the left ventricle. [5] It has two cusps: an anterior one, and a posterior one. [6] The opening of the mitral valve is surrounded by a fibrous ring known as the mitral annulus. The anterior cusp attaches to ...

    During systole, the valve closes, which means blood has just one option—to be ejected out the aortic valve and into circulation. If the mitral valve doesn’t shut all the way, blood can leak back into the left atrium, called mitral valve regurgitation. During diastole, the mitral valve opens and lets blood fill into the ventricle.

    en.wikipedia.org/wiki/Systolic_heart_murmur

    Mitral valve prolapse: This is the most common cause of late systolic murmurs. It can be heard best over the apex of the heart, usually preceded by clicks. The most common cause of mitral valve prolapse is "floppy" valve (Barlow's) syndrome. If the prolapse becomes severe enough, mitral regurgitation may occur.

    This includes aortic regurgitation (AR), mitral regurgitation (MR), and a ventricular septal defect (VSD). [4] Mitral valve prolapse: The click and the murmur of mitral valve prolapse are delayed because left atrial volume also increases due to mitral regurgitation along with increased left ventricular volume.
