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 ...

Mitral annular disjunction
Mitral annulus disjunction (MAD) is an anatomic abnormality involving the confluence of the left atrium, mitral valve annulus, and the base of the left ventricle. It is classically associated with the spectrum of myxomatous disease of the mitral valve and mitral valve prolapse (MVP).

Transcatheter mitral valve intervention
Transcatheter mitral valve interventions (TMVI) or percutaneous mitral valve interventions are less-invasive, highly technical procedures available for the management of selected patients with mitral valve regurgitation and include several transcatheter mitral valve repair (TMVr) and transcathet...

Percutaneous mitral commissurotomy
Percutaneous mitral commissurotomy (PMC) also known as percutaneous mitral balloon commissurotomy (PMBC), percutaneous mitral valvotomy (PMV) or percutaneous mitral balloon valvuloplasty (PMBV) is a transcatheter procedure for the management of mitral stenosis.

Coandă effect (physics)
The Coanda effect refers to the phenomenon by which a narrow jet of liquid (or air) passing through an orifice directly in sequence with a solid (especially convex) surface will deviate from its path and adhere to this curved surface, following its shape in parallel.
The mechanism is thought to...

Mitral leaflet separation index
The mitral leaflet separation (MLS) index is a semi-quantitative and complementary approach for assessing the degree of mitral stenosis by using two-dimensional echocardiography. It strongly correlates with the mitral valve area using planimetry and pressure half-time techniques 1-3.
