2019年6月12日 · 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, redundant chordae; eccentric jet, directed away ...

2024年8月22日 · Mitral valve regurgitation, also known as mitral valve insufficiency or mitral valve incompetence, is a valvulopathy that describes leaking of the mitral valve during systole that causes blood to flow in the reverse direction from the left ventricle into the left atrium.

2025年1月31日 · Mitral annular dilation can be found as a contributing factor of mitral regurgitation and can be found in the Carpentier types I or IIIb depending on whether it is associated with left atrial or left ventricular dilation 3. If isolated it is usually associated with …

Unilateral pulmonary edema from acute mitral regurgitation Discussion: Cardiac catheterization showed no CAD and patient had a prosthetic Carpentier Edwards mitral valve placement.

2024年10月30日 · 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 alone is replaced as seen in annuloplasty rings.

2024年12月19日 · Most commonly the mitral valve is affected, producing stenosis in later disease 2,6. Aortic regurgitation can also occur. Pathologically commissural fusion of valve leaflets is a characteristic feature. Valvular disease can develop after either a single severe episode of acute rheumatic fever or after multiple episodes 8. Radiographic features

2024年8月22日 · Mitral valve repair or mitral valvuloplasty is a surgical method for treatment of a deficient mitral valve, which comprises removal of redundant valvular tissue and fixation of ruptured/elongated chordae tendineae rather than the whole replacement of the valve.

2024年11月5日 · Mitral valve replacement has been superseded by mitral valve repair in most situations of mitral valve dysfunction 1-3. Further existing indications of operative mitral valve replacement include the following 1-3: irreparable mitral valve pathology. expected poor durability outcomes with mitral valve repair. significant mitral annular calcification

If the left atrium enlarges, extends towards and also abuts the right lung, a second interface between heart (the left atrium) and lung forms: this is the double density sign. The cardiac MRI showed that the left atrial enlargement was due to severe mitral regurgitation.
