Calculation of the continuity equation can be usually made in every echomachine, but in case this is not possible, hier an online calculator of the Canadian Society of Echocardiography. aortic–mitral continuity Fan Wang1, Xuelian Song1, Yi Dang1, Shangzhi Shu2 and Shuyan Li2 Abstract Catheter ablation of accessory pathways can be challenging depending on the location of these pathways, and accessory pathways are rare through the aortic cusps. We report a patient who 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. Abstract The anatomic relationship of the aortic and mitral valves is a useful landmark in assessing congenital heart malformations.
Anterior accessory pathways can be safely and effectively ablated … 2002-01-01 mitral continuity (AMC).9 This area, also known as the aortomitral curtain or intervalvular fibrosa, can become heavily calcified in patients with severe degenerative aortic or mitral valve disease.10 Increased thickness of AMC has been associated with an increase in postsurgi-cal complications in the setting of mitral valve surgery.11 Aortic Regurgitation (AR) Evaluation by 2-D and Doppler Echo •Echocardiography remains the imaging modality of choice for the diagnosis of the mechanism and the quantitation of severity of AR •Careful application of the concepts of the continuity equation are needed for accurate quantitation of AR •Quantitation of AR is the sum of all 2-D The calcification burden of the aortomitral continuity as a whole (AMCC mass, including the aortic valve, left ventricular outflow tract, and mitral annulus and/or valve), isolated aortic valve (AVC mass), and coronary arteries (Agatston score and CAC score) were quantified from unenhanced CT scans by using commercially available software (Aquarius iNtuition; TeraRecon, Foster City, Calif 1.

Saad M, Roushdy A, Jmeian A 2017-02-23 Aortic Stenosis: Breaking Down the Continuity Equation The evaluation and screening of aortic stenosis is a routine calculation performed on all complete echocardiograms. The detailed evaluation involves multiple key parameters that make up the equation that determines the aortic valve area (AVA).
A continuous wave doppler (CWD) of the LVOT could be obtained, but, since the CWD introduces ambiguity into the equation and since flows in the LVOT rarely exceed the aliasing velocity of the pulse wave doppler, PWD is the best measurement mode. However, in aortic regurgitation, there is excessive flow, so aliasing may occur.

According to the continuity equation, flow across the mitral valve is equal to flow across the aortic valve. Using pulsed wave Doppler, the volume flowing across the aortic valve (i.e stroke volume ) and the mitral valve can be calculated.

Findings from our case suggest that an AP located in this area can be successfully ablated from the LCC. In conclusion, an AV AP can be present and successfully ablated at rare locations, such as the left aortic sinus of Valsalva near the aortic–mitral continuity, after failure to 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 ]. endocardium to the anterior mitral leaflet parallel to the aortic valve plane andendocardium to the anterior mitral leaflet, parallel to the aortic valve plane and within 0.5–1.0 cm of the valve orifice European Journal of Echocardiography 2009;10:1-25 Unlocking Prognostic Information from Cardiac CT: Does Aortic Mitral Continuity Calcification Matter?
Stroke volume, the amount of blood ejected into the aorta, is calculated by measuring the area and VTI in the LVOT: SV = area LVOT • VTI LVOT. In conclusion, an AV AP can be present and successfully ablated at rare locations, such as the left aortic sinus of Valsalva near the aortic–mitral continuity, after failure to achieve ablation along the mitral annulus. A continuous wave doppler (CWD) of the LVOT could be obtained, but, since the CWD introduces ambiguity into the equation and since flows in the LVOT rarely exceed the aliasing velocity of the pulse wave doppler, PWD is the best measurement mode. However, in aortic regurgitation, there is excessive flow, so aliasing may occur.

However, the mitral-aortic separation increased from 0.34 +/- 0.02 mm in normal hearts to 0.82 +/- 0.25 mm in stage 18, 1.11 +/- 0.36 mm in stage 21 and 0.75 +/- 0.33 mm in stage 24 permanent loop experimental hearts (p less than 0.01).

She had undergone mitral valve Mitral-aortic (M-A) discontinuity is an uncommonly ob-served congenital malformation. From the embryologic point of view, it is a failure of the superior endocardial cushion of the A-V canal reach and insert into the aortic root (the mitral-aortic fibrous trigone). It should be dif-ferentiated from aorto-left ventricular discontinuity, a 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.
