The interactions of mitral and aortic annuli correlate with the left ventricular to each other via fibrous tissue, which is also called the aortomitral curtain (8).

The aortic (AV) and mitral (MV) valves are coupled via a common fibrous continuity known as the aortic–mitral curtain or intervalvular fibrosa . As a result, the physiological function of either of these two valves involves the complementary function of the other [ 2 ].

This is especially common in prosthetic aortic valve endocarditis. In (A), the infected aortic valve has The posterior leaflet is in continuation with the anterior leaflet of the mitral valve (the tissue is called the aorto-mitral curtain). The aortic valve is opened during systole, the driving force for it to open is the difference in pressure between the contracting left ventricle of the heart and the aorta. along with valvular lesions, the aorto-mitral curtain (AMC, junction between base of anterior mitral leaﬂet and aortic root) thickness is increased on transthoracic echocardiography. We sought to identify clinical and transthoracic echocardiography predictors of long-term mortality in patients with RACD.

Andrew Murphy and Dr Francis Deng et al. 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 Figure 2 Aortic valve endocarditis can extend below the aortic valve into the aorto-mitral curtain. 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.

A common structure, the subaortic curtain, 14–17 simultaneously supports 2 of the aortic cusps (left coronary and noncoronary) and the anterior leaflet of the mitral valve. 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.

The aortic leaflet (AL) forms the posterior wall of the LVOT. 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 annulus was increased from 21 mm to 27 mm for a mechanical AVR. Patient was discharged without blood transfusion or any complications. Our enlargement technique was simple and effective to enlarge the aortic annulus for mechanical AVR. along with valvular lesions, the aorto-mitral curtain (AMC, junction between base of anterior mitral leaﬂet and aortic root) thickness is increased on transthoracic echocardiography.

3D solid elements were used to model the aorta, aortic root, valves, aortic-mitral curtain, calcification and myocardium, truss elements were used for the mitral chordae, while shell elements were used for the endocardial wall. Five-hundred and fifty-seven (557) subjects received isolated aortic replacement, 176 received isolated mitral replacement, and 29 received replacement of both the aortic and mitral valves. The cumulative follow-up for all subjects was 773.51 patient-years with a mean follow-up of 1.02 patient-years (s.d. = 0.71 patient-years, range 0 – 3.10 patient-years).

Aggressive debridement may result in atrioventricular groove disruption, circumflex injury, paravalvular leak (PVL), or stroke.1 In high-risk patients with MAC, a transcatheter aortic valve replacement (TAVR) in the mitral position via a transapical, trans-septal, or Redo double valve replacement (aortic & mitral valves) with aorto-mitral continuity (Mitral-aortic Intervalvular Fibrosa, MAIVF) reconstruction a patient wit Aorto-mitral curtain thickness of at least 0.6 cm was associated with significantly increased mortality. Conclusions Patients with RACD undergoing cardiothoracic surgery have high long-term mortality, which is independently predicted by AMC thickness, a higher preoperative risk score, and lack of cardioprotective medications.

There are two main mechanisms of extension of the infection from the aortic valve to the mitral valve: (1) aortic annular abscess that extends to the aortomitral curtain or intervalvular fibrous curtain and anterior mitral leaflet (Fig. 7.13), and (2) the aortic regurgitation caused by IE of the aortic valve, causing a “kissing lesion” on the secondarily infected anterior mitral leaflet. DISCUSSION.

There is continuity between the anterior leaflet of the mitral valve and the left and non-coronary cusp of the neighboring aortic valve, referred to as the aortic-mitral curtain. Mitral annular calcification (MAC) represents a challenging pathology associated with significant morbidity after surgery. Aggressive debridement may result in atrioventricular groove disruption, circumflex injury, paravalvular leak (PVL), or stroke.1 In high-risk patients with MAC, a transcatheter aortic valve replacement (TAVR) in the mitral position via a transapical, trans-septal, or 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 mitral valve is also called a bicuspid valve and plays an important role in your heart. Here's more information about the heart's mitral valve, its function and some of the diseases that affect the mitral valve.
