Prosthetic heart valve

Prosthetic heart valves are common. The four valves of the heart may all be surgically replaced. However, the aortic and mitral valves are the most commonly replaced. Replacements may be tissue or metallic valves, only the latter being visualized on imaging investigations. Sometimes the annulus...

Carpentier classification of mitral valve regurgitation

The Carpentier classification divides mitral valve regurgitation into three types based on leaflet motion 1: type I: normal leaflet motion annular dilation, leaflet perforation regurgitation jet directed centrally type II: excessive leaflet motion papillary muscle rupture, chordal rupture, ...

Diastolic dysfunction assessment (echocardiography)

According to the American Society of Echocardiography and the European Association of Cardiovascular Imaging, diastolic dysfunction assessment on echocardiography is divided into two different groups based on left ventricular systolic function.  Normal left ventricular systolic function There ...

Myxomatous mitral valve degeneration

Myxomatous mitral valve degeneration, myxomatous degeneration of the mitral valve, myxomatous mitral valve disease or simply myxomatous mitral valve is a non-inflammatory progressive alteration of the mitral valve structure associated with mitral valve prolapse and mitral insufficiency. Termino...

Mitral valve leaflet calcification

Mitral valve leaflet calcification or mitral leaflet calcification refers to the deposition of calcium on the mitral valvular leaflets as opposed to mitral annular calcification in the mitral annulus. It has been associated with mitral stenosis 1,2.  Epidemiology Mitral leaflet calcification h...

Mitral valve replacement

Mitral valve replacement refers to the substitution of the mitral valve either by a mechanical valve or bioprosthesis. Indications Mitral valve replacement has been superseded by mitral valve repair in most situations of mitral valve dysfunction 1-3. Further existing indications of operative m...

Flail leaflet

Flail leaflet or leaflet flail refers to an abnormally increased leaflet mobility of the atrioventricular valves associated with valvular prolapse and a systolic excursion of the leaflet tip or edge into the atria. Pathology Flail leaflet can be seen in leaflets of the mitral and tricuspid val...

Mitral annular dilation

Mitral annular dilation refers to an increased mitral annulus in relation to the size of the mitral valvular leaflets and is a potential cause for mitral regurgitation. Epidemiology Associations Mitral annular dilation is seen in the following clinical conditions 1-3: secondary mitral regurg...

Reduced leaflet motion

Reduced leaflet motion refers to an abnormally decreased mobility of one or more valvular leaflets and is a phenomenon that has been observed after (transcatheter) implantation of prosthetic heart valves and gained clinical significance for the diagnosis of subclinical leaflet thrombosis. Epide...
