2018-03-02 · The aortic-mitral curtain is a fibrous thickening separating the aortic valve leaflets from the mitral valve proper. On either end of the aortic-mitral curtain is a triangular junction of fibrous tissue known as the right and left fibrous trigones (Figure 4 & 5).

Abstract The anatomic relationship of the aortic and mitral valves is a useful landmark in assessing congenital heart malformations. The atrioventricular and semilunar valve regions originate in wi 2018-03-02 2020-12-26 These are collectively called the aortic–mitral continuity. Additionally, expansion of fibrous tissue at either extreme of the area of continuity forms the right and left fibrous trigones. 1984-01-15 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. Extensive infective endocarditis of the aortic root and the aortic-mitral continuity: a mitral valve sparing approach† Extensive IE of the aortic root with destruction of the surrounding tissues remains a complex disease with high morbidity and mortality rates. Our technique allows native mitral valve preservation but is technically challenging.

In particular, uncontrolled IE of the aortic valve can cause destruction of the aortic root and, subsequently, the aortic-mitral continuity and the mitral valve. Infection of the aortic-mitral continuity has been reported in 10.6% of cases of left-sided IE [ 2] and in 47.1% of patients with aortic root abscess [ 3 ].

The atrioventricular and semilunar valve regions originate in widely separated parts of the early embryonic heart tube, and the process by which the normal fibrous continuity between the aortic and mitral valves is acquired has not been clearly defined. The aortomitral continuity (also known as the aortomitral curtain, aorticomitral junction, intervalvular fibrous body ) is a fibrous sheet located between the noncoronary and left coronary leaflets of the aortic valve and anterior leaflet of the mitral valve . It is attached by the left and right fibrous trigones to the left ventricular myocardium. Background— The aortomitral continuity (AMC) has been described as a site of origin for ventricular tachycardias (VT) in structurally normal hearts.

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.

(B) The aortic leaflet of the mitral valve cut in profile shows the atrial wall (blue arrows) reaching the leaflet. Grey dots mark the region of fibrous continuity between aortic and mitral valves. Figure 3 A dissection showing the left (L) and right (R) fibrous This area is called mitral–aortic fibrous continuity, also known as mitral–aortic curtain or intervalvular fibrosa (Fig. 16‑2). Two nodules of dense fibrous tissue namely the “right and left fibrous trigons” near the commissures exist to reinforce the base of anterior leaflet.

The detailed evaluation involves multiple key parameters that make up the equation that determines the aortic valve area (AVA). The Aortic Valve Area Continuity Equation. Calculating the aortic valve area by using the continuity equation is a relatively simple method to use.

The imaging revealed late Gd enhancement (LGE) mainly in the basal midlayer of the anteroseptal wall to aorta‐mitral continuity (AMC) just below the prosthetic aortic valves in both cases (Figure 4). We also performed cardiac MRI for two patients in the control group who had positive SAECG and NSVT in Holter.
