Operative findings showed an extracardiac aneurysm of the interleaflet triangle above the aortic-mitral curtain. Because there was no sign of active inflammation, the orifice was closed with an autologous pericardial patch, and the aortic valve was replaced with a mechanical valve.

The treatment of mitral valve stenosis is discussed including percutaneous mitral balloon valvotomy and mitral valve replacement. The treatment of mitral stenosis relies on the prevention or early recognition of rheumatic heart disease. Pro

This is especially common in prosthetic aortic valve endocarditis. In (A), the infected aortic valve has been removed, revealing destruc-tion of the aorto-mitral curtain below the aortic annulus. Involvement of the intervalvular fibrous body [aorto-mitral curtain (AMC)] is rarer in patients with endocarditis. Reconstruction of the AMC during double-valve surgery may be the only alternative for treating patients with infective endocarditis with abscess or vegetations, inadequate intervalvular fibrous tissue to secure a prothesis valve.

The aortic-mitral curtain is the fibrous tissue between the anterior mitral valve leaflet, the left and non-coronary cusps of the aortic valve, and the left and right trigone. 3 The posterior portion of the annulus is less developed owing to the discontinuity of the fibrous skeleton of the heart in this region. Aortic-mitral curtain Anterior mitral leaflet Inter-atrial septum Left and/or right atria Right atrium Right atrium Membranous septum Conduction system Normal aortic valve (AV) and mitral valve (MV) function in a reciprocal interdependent fashion. We hypothesized that MV function would be affected by severe aortic stenosis (AS) and that it would remain altered after transcatheter AV replacement (TAVR). An intertrigonal sheet of fibrous tissue between the aortic anulus and the anterior leaflet of the mitral valve.

When the mitral and aortic heart valves fail to open and close properly, the heart's ability to pump blood adequately through the body is hampered.

The chordae arising from each papillary muscles (PM) insert on both the mural and aortic leaflets of the mitral valve. The boundary of the rough zone (RZ) is shown by dotted red line. Direction of blood flow is shown by yellow arrows. The aortic and mitral valve share a common fibrous border call the aortic-mitral curtain. Due to this anatomic linkage, normal aortic and mitral valve function are interdependent demonstrating coupled reciprocal behavior.

Extensive surgical debridement and mitroaortic curtain reconstruction is required in order to eradicate the infection. The fact that most of affected patients have had previous valve replacements brings additional challenges regarding optimal surgical exposure of the mitral valve annulus. Involvement of the intervalvular fibrous body [aorto-mitral curtain (AMC)] is rarer in patients with endocarditis. Reconstruction of the AMC during double-valve surgery may be the only alternative for treating patients with infective endocarditis with abscess or vegetations, inadequate intervalvular fibrous tissue to secure a prothesis valve.

Aortic mitral curtain





The aortic and mitral valve share a common fibrous border call the aortic-mitral curtain. Due to this anatomic linkage, normal aortic and mitral valve function are interdependent demonstrating coupled reciprocal behavior. Thus, during the cardiac cycle when aortic annular area is at its maximum, mitral annular area is at its minimum and vice versa.

It is attached by the left and right fibrous trigones to the left ventricular myocardium. Abstract.

18 Jun 2014 Destruction of the mitral–aortic (or mitroaortic) intervalvular fibrosa (IVF) by infective endocarditis is a marker of advanced pathology. Patients 

In other words, at the MA-Ao junction, the left atrial wall does not join the left ventricular wall but is attached to the aorta. Involvement of the mitroaortic curtain as a complication of infective endocarditis constitutes a serious medical condition. Extensive surgical debridement and mitroaortic curtain reconstruction is required in order to eradicate the infection.
