Chordae Tendineae
The tendinous cords that connect each cusp of the two atrioventricular HEART VALVES to appropriate PAPILLARY MUSCLES in the HEART VENTRICLES, preventing the valves from reversing themselves when the ventricles contract.
Heart Rupture
Disease-related laceration or tearing of tissues of the heart, including the free-wall MYOCARDIUM; HEART SEPTUM; PAPILLARY MUSCLES; CHORDAE TENDINEAE; and any of the HEART VALVES. Pathological rupture usually results from myocardial infarction (HEART RUPTURE, POST-INFARCTION).
Mitral Valve
The valve between the left atrium and left ventricle of the heart.
Mitral Valve Insufficiency
Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.
Mitral Valve Prolapse
Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.
Rupture
Forcible or traumatic tear or break of an organ or other soft part of the body.
Tricuspid Valve
The valve consisting of three cusps situated between the right atrium and right ventricle of the heart.
Papillary Muscles
Conical muscular projections from the walls of the cardiac ventricles, attached to the cusps of the atrioventricular valves by the chordae tendineae.
Rupture, Spontaneous
Tear or break of an organ, vessel or other soft part of the body, occurring in the absence of external force.
Heart Valve Prosthesis Implantation
Surgical insertion of synthetic material to repair injured or diseased heart valves.
Echocardiography
Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.

Chordal force distribution determines systolic mitral leaflet configuration and severity of functional mitral regurgitation. (1/118)

OBJECTIVES: The purpose of this study was to investigate the impact of the chordae tendineae force distribution on systolic mitral leaflet geometry and mitral valve competence in vitro. BACKGROUND: Functional mitral regurgitation is caused by changes in several elements of the valve apparatus. Interaction among these have to comply with the chordal force distribution defined by the chordal coapting forces (F(c)) created by the transmitral pressure difference, which close the leaflets and the chordal tethering forces (FT) pulling the leaflets apart. METHODS: Porcine mitral valves (n = 5) were mounted in a left ventricular model where leading edge chordal forces measured by dedicated miniature force transducers were controlled by changing left ventricular pressure and papillary muscle position. Chordae geometry and occlusional leaflet area (OLA) needed to cover the leaflet orifice for a given leaflet configuration were determined by two-dimensional echo and reconstructed three-dimensionally. Occlusional leaflet area was used as expression for incomplete leaflet coaptation. Regurgitant fraction (RF) was measured with an electromagnetic flowmeter. RESULTS: Mixed procedure statistics revealed a linear correlation between the sum of the chordal net forces, sigma[Fc - FT]S, and OLA with regression coefficient (minimum - maximum) beta = -115 to -65 [mm2/N]; p < 0.001 and RF (beta = -0.06 to -0.01 [%/N]; p < 0.001). Increasing FT by papillary muscle malalignment restricted leaflet mobility, resulting in a tented leaflet configuration due to an apical and posterior shift of the coaptation line. Anterior leaflet coapting forces increased due to mitral leaflet remodeling, which generated a nonuniform regurgitant orifice area. CONCLUSIONS: Altered chordal force distribution caused functional mitral regurgitation based on tented leaflet configuration as observed clinically.  (+info)

Ten-year experience of chordal replacement with expanded polytetrafluoroethylene in mitral valve repair. (2/118)

BACKGROUND: Mitral valve repair is the procedure of choice to correct mitral regurgitation (MR). Although chordal replacement with expanded polytetrafluoroethylene (ePTFE) has been widely accepted to repair anterior mitral prolapse and other difficult situations, the long-term results of the repair and the fate of ePTFE have not been delineated. METHODS AND RESULTS: From July 1988 to April 1999, 74 patients (49 males, 25 females) aged 17 to 77 years (mean age 55. 3+/-14.8 years) underwent mitral valve repair with chordal replacement with ePTFE. The follow-up period was from 6 months to 11. 3 years (mean 4.6+/-3.2 years). The causes of MR were degenerative in 65 patients (88%) and infective in 9 (12%). Three patients had active infective endocarditis. Valve lesions were anterior in 35 patients, posterior in 10, and both anterior and posterior in 29. Various procedures for plasty of leaflets were necessary in 37 patients (50%). Atrial fibrillation was associated in 38 patients (51%), and the maze procedure has been performed in a selected group of 30 patients (41%) since July 1992. There was 1 in-hospital death (1.4%) and 3 late cardiac deaths (4.1%). More than moderate MR developed in 12 patients (17%) during the follow-up period. Three of these patients required early reoperation within 1 year due to hemolysis. Two patients underwent mitral valve replacement at 6 and 8 years after repair, respectively. The actuarial reoperation-free rates at 5 and 10 years were 94.3+/-2.8% and 81.7+/-9.1%, respectively. Sinus rhythm was restored in 21 patients (70%) with the maze procedure. There was only 1 thromboembolic episode (0. 3%/patient-y) in a patient with atrial fibrillation who did not undergo the maze procedure. Event-free survival rates as assessed by the freedom from cardiac death, thromboembolism, reoperation, and anticoagulation-related hemorrhage at 5 and 10 years were 91.3+/-3. 4% and 71.6+/-9.7%, respectively. There was no relationship between recurrent MR and the change of ePTFE. Structural analysis of the ePTFE resected during reoperation revealed no calcification and showed remaining flexibility and pliability. Protein infiltration was observed in the ePTFE, and collagenous proliferation was recognized at the site of fixation to the valve leaflet and the papillary muscle. The surface of the ePTFE was completely endothelialized, which may induce antithrombogenicity. CONCLUSIONS: The long-term durability and biological adaptation of ePTFE as artificial chordae for mitral valve repair of MR were proved for >10 years.  (+info)

Mitral valve repair in a predominantly rheumatic population. Long-term results. (3/118)

Valve repair in rheumatic patients poses special problems due to valve deformity and mixed lesions. We present our experience from January 1988 through June 1999, in this retrospective study of 818 patients (377 males). The mean age was 22.8 +/- 11.3 years (range, 2 to 70 years). The cause of mitral regurgitation was rheumatic in 718 (88%) patients, congenital in 51, myxomatous in 34, infective in 7, and ischemic in 8. Most patients (64%) were in New York Heart Association functional class III or IV. Congestive heart failure was present in 116 patients (14%). Reparative procedures included posterior collar annuloplasty (n=710), commissurotomy (n=482), cusp-level chordal shortening (n=237), cusp thinning (n=222), cleft suture (n= 166), and cusp excision/plication (n=42). Operative mortality was 4% (32 patients). Preoperative left ventricular dysfunction, presence of congestive heart failure, and advanced functional class were associated with greater mortality. Follow-up ranged from 1 to 144 months (mean, 44.9 +/- 33.2 months) and was 96% complete. Most survivors (70%) had no or trivial mitral regurgitation. Forty patients required reoperation for valve dysfunction. There were 23 (2.8%) late deaths. Actuarial, reoperation-free, and event-free survival at 11 years were 92.6% +/- 1.0%, 65.0% +/- 10%, and 38% +/- 6.0%, respectively Among the survivors, 85% were in New York Heart Association functional class I. We conclude that mitral valve repair in rheumatic patients, using current techniques, can effectively correct hemodynamic and functional abnormalities with satisfactory results.  (+info)

Anterior chordal transection impairs not only regional left ventricular function but also regional right ventricular function in mitral regurgitation. (4/118)

BACKGROUND: Preservation of annuloventricular continuity through the chordae tendinae aims to maintain left ventricular (LV) function and thus improve postoperative prognosis. This study was designed to prospectively investigate the effect of anterior chordal transection on global and regional LV and right ventricular (RV) function in mitral regurgitation (MR). METHODS AND RESULTS: Sixty-five patients with severe MR underwent radionuclide angiography before and after either mitral valve (MV) repair (42 patients) or replacement with anterior chordal transection (23 patients). LV and RV ejection fractions (EF) were determined at rest. Both ventricles were divided into 9 regions to analyze regional EF and the effect of anteromedial translation related to surgery. After surgery there was a significant decrease in LVEF (P=0.038) and an increase in RVEF (P=0.036). However, LVEF did not change after MV repair (63.8+/-9.9% to 62.6+/-10.3%), whereas RVEF improved (40.7+/-10.1% to 44.5+/-8.1%, P=0.027). In contrast, LVEF decreased after MV replacement (61.7+/-10.1% to 57.2+/-9.9%, P=0.03), and RVEF was unchanged (40.9+/-10.9% to 41.3+/-9.1%). LVEF 4 and 5, in the area of anterior papillary muscle insertion, were impaired after MV replacement compared with MV repair (region 4, 77.6+/-16.7% versus 87.7+/-10.8%, P=0.005, and region 5, 73.9+/-19.3% versus 89.9+/-13.1%, P<0.001). Moreover, anterior chordal transection led to a significant impairment in the apicoseptal region of the RV (RVEF 4, 50.3+/-15.6% versus 59.3+/-13.8%, P=0.02). CONCLUSIONS: Anterior chordal transection during MV replacement for MR impairs not only regional LV function but also regional RV function.  (+info)

Chordal cutting: a new therapeutic approach for ischemic mitral regurgitation. (5/118)

BACKGROUND: Mitral regurgitation (MR) conveys adverse prognosis in ischemic heart disease. Because such MR is related to increased leaflet tethering by displaced attachments to the papillary muscles (PMs), it is incompletely treated by annular reduction. We therefore addressed the hypothesis that such MR can be reduced by cutting a limited number of critically positioned chordae to the leaflet base that most restrict closure but are not required to prevent prolapse. This was tested in 8 mitral valves: a porcine in vitro pilot with PM displacement and 7 sheep with acute inferobasal infarcts studied in vivo with three-dimensional (3D) echo to quantify MR in relation to 3D valve geometry. METHODS AND RESULTS: In all 8 valves, PM displacement restricted leaflet closure, with anterior leaflet angulation at the basal chord insertion, and mild-to-moderate MR. Cutting the 2 central basal chordae reversed this without prolapse. In vivo, MR increased from 0.8+/-0.2 to 7.1+/-0.5 mL/beat after infarction and then decreased to 0.9+/-0.1 mL/beat with chordal cutting (P<0.0001); this paralleled changes in the 3D leaflet area required to cover the orifice as dictated by chordal tethering (r(2)=0.76). CONCLUSIONS: Cutting a minimum number of basal chordae can improve coaptation and reduce ischemic MR. Such an approach also suggests the potential for future minimally invasive implementation.  (+info)

Transaortic double valve replacement with total chordal preservation. (6/118)

Very few cases of transaortic double valve replacement have been reported in the literature. A 26-year-old man presented to us with severe aortic regurgitation, mitral valve thickening, and mild mitral regurgitation 6 years after he had undergone a Ross procedure and open mitral commissurotomy. At his 2nd operation, he underwent transaortic double valve replacement with total chordal preservation of the mitral apparatus. Due to recurrent rheumatic activity, this patient had experienced a recurrence of valvulopathy Because we have observed this in other young patients with rheumatic heart disease, we no longer perform the Ross procedure in such patients, especially if there is associated mitral valve disease. In selected patients with dilated aortic annulus, the transaortic approach provides excellent access for safe mitral valve replacement with total chordal preservation. The surgical technique and a brief review of the literature are presented.  (+info)

Papillary fibroelastoma of the tricuspid valve chordae with a review of the literature. (7/118)

Endothelial papillary fibroelastomas represent a rare entity in cardiac pathology that at times may be associated with embolisation, angina, and sudden death. We report on a case of a 46-year-old woman with a papillary fibroelastoma originating on the chordae of the tricuspid valve. The tumour was discovered incidentally using transthoracic two-dimensional echocardiography. The patient had an uneventful recovery and remained free of symptoms after six months.  (+info)

Anterior mitral leaflet mobility is limited by the basal stay chords. (8/118)

BACKGROUND: We hypothesize that 2 tendon-like anterior basal stay chords, which remain taut during the entire cardiac cycle, limit the motion of the anterior mitral leaflet. METHODS AND RESULTS: Sonomicrometric crystals were implanted in 6 sheep at the insertion of stay chords at anterior mitral leaflet (S1 and S2), papillary muscle tips, fibrous trigones, mitral annulus, and the tip of the anterior leaflet (AL). Distances between crystals were recorded before and after section of stay chords. During the cardiac cycle, the angle alpha between mitral annulus and AL changed by +54.2+/-12.4 degrees; the angles between mitral annulus and S1 (beta1) changed by +25.7+/-14.6 degrees, and between mitral annulus and S2 (beta2) by +20.4+/-7.8 degrees. During diastole, AL twice crossed the virtual plane formed by the stay chords: during E-wave by a maximum of 6.5 mm (mean, 2.5+/-2.2 mm) and during A-wave by a maximum of 3.2 mm (mean, 1.7+/-0.9 mm). After section of both stay chords, total anterior mitral leaflet motion increased as follows: AL, +6.9+/-3.4 degrees; S1, +13.1+/-4.4 degrees; and S2, +30.9+/-11.7 degrees (P<0.05). CONCLUSIONS: Although the lateral movement of anterior mitral leaflet is limited by stay chords, the midportion moves unimpaired toward the septum, like a sail, between the 2 stay chords during diastole. A diastolic left ventricular-inflow and systolic left ventricular-outflow funnel mechanism is created. Stay chord section increased lateral anterior mitral leaflet movement.  (+info)

Heart valve - WikipediaHeart valve - Wikipedia
These are the mitral and tricuspid valves, which are situated between the atria and the ventricles and prevent backflow from the ventricles into the atria during systole. They are anchored to the walls of the ventricles by chordae tendineae, which prevent the valves from inverting. The chordae tendineae are attached to papillary muscles that cause tension to better hold the valve. Together, the papillary muscles and the chordae tendineae are known as the subvalvular apparatus. The function of the subvalvular apparatus is to keep the valves from prolapsing into the atria when they close. The subvalvular apparatus has no effect on the opening and closure of the valves, however, which is caused entirely by the pressure gradient across the valve. The peculiar insertion of chords on the leaflet free margin, however, provides systolic stress sharing between chords according to their different thickness.[7] The closure of the AV valves is heard as lub, the first heart sound (S1).

BACKGROUND: Common surgical procedures on the mitral valve of the heart include modifications to the chordae tendineae. Such interventions are used when there is extensive leaflet prolapse caused by chordae rupture or elongation. Understanding the role of individual chordae tendineae before operating could be helpful to predict whether the mitral valve will be competent at peak systole. Biomechanical modelling and simulation can achieve this goal. METHODS: We present a method to semi-automatically build a computational model of a mitral valve from micro CT (computed tomography) scans: after manually picking chordae fiducial points, the leaflets are segmented and the boundary conditions as well as the loading conditions are automatically defined ...

Mitral prolapse is a common cardiac disease whose patients are at higher risk for serious complications. Mitral valve (MV) repair offers several important advantages compared with valve replacement and it achieves excellent midterm and long-term results. Two major problems of using pre-measured expanded polytetrafluoroethylene(ePTFE) neochordae (the loop technique) are deciding the length of the neochordae and tying the knot at the intended length. Therefore, a great need still exists to find new method to simplify and precise the length of neochordae. 20 patients with mitral valve prolapse who undergo mitral valve repair using neochorda will be recruited in this study. Trans thoracic echocardiography (TTE) will be done preoperatively for all patients. Two, three, and four chamber view of each patient will be pre-operatively recorded. The device will be set with extracted measurements. Artificial corda loops are made using CV-4 ePTFE sutures. After artificial chordae replacement, the ring ...

A brief summary of ACR history is given, as well as basic techniques of ACR placement and length adjustment. Several cases then are presented, and operative videos are correlated with pre- and post-operative transesophageal echocardiograms. Three procedures involving isolated posterior leaflet prolapse are shown, one repaired with open ACR, and two with robotic methods. Then, a patient with true commissural prolapse is illustrated, managed with ACR to both leaflets. A Barlows valve with annular calcification and generalized segmentation and prolapse is treated with annular decalcification and 4 sets of artificial chords. A patient with a previous failed repair underwent complex re-repair, including ACR to a prolapsing commissural cusp. Posterior leaflet augmentation with gluteraldehyde-fixed autologous pericardium also is used. Approaches to repairing valves with advanced rheumatic ...

A murmur of mitral regurgitation in patients with congestive heart failure after an acute myocardial infarction suggests a surgically correctable cause of the heart failure. Six patients who presented in this manner and who later underwent surgery have been evaluated by two-dimensional echocardiography (2DE). The underlying anatomical cause of the mitral regurgitation was correctly identified as papillary muscle rupture (2 cases), ruptured chordae tendineae (1 case) and papillary muscle fibrosis (3 cases).. Two-dimensional echocardiography is useful in evaluating patients with congestive heart failure who develop a systolic murmur after acute infarction, as it can detect surgically correctable structural defects.. ...

The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction).[1] The papillary muscles constitute about 10% of the total heart mass.[2] ...

Atrial Functional Mitral Regurgitation | JACC: Journal of the American College of CardiologyAtrial Functional Mitral Regurgitation | JACC: Journal of the American College of Cardiology
Moderate or greater mitral regurgitation (MR) is the most frequent valve disease in the United States, with a prevalence (exceeding 2 million people in 2002) that is anticipated to double by 2030 (2,3). Competence of the mitral valve requires a temporally and spatially coordinated interaction of the mitral leaflets with the annulus, chordae tendinae, and papillary muscles; dysfunction of any of these components will affect the normal systolic coaptation of the anterior and posterior leaflets and cause mitral regurgitation. Mechanistically, MR is classified as either primary (i.e., intrinsic valve disease) or functional, and is further subclassified by the degree of leaflet mobility. Functional MR occurs in patients with a structurally normal valve (generally with restricted leaflet mobility), mitral annular dilation, and left ventricular remodeling (4); whether annular dilation alone (no left ventricular [LV] remodeling, normal leaflet mobility) is sufficient for the development of MR is ...

Now lets take a closer look at the valves. All of the hearts valves allow blood to flow one way but not the other. They open to let blood pass through, and then quickly snap shut. They keep blood moving in the right direction through the heart. The tricuspid and mitral valves are called the atrioventricular valves. The tricuspid valve has three flaps (called cusps or leaflets) and the bicuspid valve has two. These valves are connected to the papillary muscles of the heart by thin, tendon-like strings called chordae tendineae. The pulmonary valve and the aortic valve are called the semilunar valves. They normally have three flaps. ...

Parachute mitral valve (PMV) is a congenital heart anomaly which consists of a unifocal attachment of the mitral valve chordae into a single or dominant papillary muscle. This morphological anomaly determines the impairment of mitral leaflet motion, resulting in different grades of mitral stenosis. Due to its frequent association with other congenital cardiac defects requiring surgical correction, the therapy of a relevant stenotic PMV is usually represented by surgical commissurotomy. Herein is reported the case of a PMV treated by surgery in infancy, which showed a severe restenosis after 34 years and was successfully treated by percutaneous valvuloplasty with the additional creation of a restrictive atrial communication ...

So knowing the grade of a murmur isnt all that informative as it doesnt give you a good picture of how the heart is actually functioning - but a color Doppler ultrasound (echocardiogram) when done by a specialist with training and experience (versus a GP vet simply with enough money to purchase an ultrasound machine) is very informative. That test will show the functioning of the valves, and you can see changes in the valve leaflets, whether or not there are ruptured chordae tendinae, whether there is valve prolapse; you can see the regurgitant flow and measure the velocity of the regurg, and you can get exact measurements of the cardiac chambers and compare them to normal measurements. Other complications such as whether or not pulmonary hypertension is present can also be measured by an echo. Another important measurement obtained from an echo is contractility or shortening fraction, which is given in a percentage (like 20% or 50%). This is a measurement of the pumping strength/ability of ...

MVD (Heart Disease) Part 3 - Cavalier MattersMVD (Heart Disease) Part 3 - Cavalier Matters
Bands of fibrous tissue, known as the heart chords or strings (the chordae), form part of the heart structure. The chords increase and decrease in tension causing the valves to open and close. When the chords rupture, it causes sudden shortness of breath. When this occurs it is essential a vet or Cardiologist sees your Cavalier.. He may be given oxygen while the heart remodels itself and your Cavalier will become more comfortable.. ...

NewYork-Presbyterian Queens - Conditions A-Z - Mitral Valve Prolapse
Treatment is not usually necessary as MVP is rarely a serious condition. Regular checkups with a physician are advised.. Persons with rhythm disturbances may need to be treated with beta blockers or other medications to control tachycardias (fast heart rhythms). In most cases, limiting stimulants such as caffeine and cigarettes is all that is needed to control symptoms.. If atrial fibrillation or severe left atrial enlargement is present, treatment with an anticoagulant may be recommended. This can be in the form of aspirin or warfarin (Coumadin®) therapy.. For the person with symptoms of dizziness or fainting, maintaining adequate hydration (fluid volume in the blood vessels) with liberal salt and fluid intake is important. Support stockings may be beneficial.. If severe mitral regurgitation resulting from a floppy mitral leaflet, rupture of the chordae tendineae, or extreme lengthening of the valve should occur, surgical repair may be indicated.. ...

The incidence and etiological classification of valvular diseases were examined on 358 cases from 3,000 consecutive autopsies of more than 60 years of age. The incidence of valvular disease was 11.9% (358 out of 3,000 cases). Mitral stenosis was found in 23 cases (6.4%), of which 21 cases were rheumatic and the remaining 2 were mitral ring calcification (MRC). Mitral regurgitation was observed in 126 cases (35.3%): 69 of papillary muscle dysfunction, 26 of mitral valve prolapse (MVP), 16 of MRC, 9 of ruptured chordae tendineae, 3 of rheumatic and 3 of congenital. Aortic stenosis was noted in 33 cases (9.2%): 27 of calcified, 5 of rheumatic and one of congenital. Aortic regurgitation was found in 169 cases (47.2%): 112 of degenerative, 47 of syphilitic, 7 of rheumatic and 2 of aortitis syndrome. There were 6 cases (1.7%) of tricuspid regurgitation. Etiological classification revealed 6 cases (1.7%) of congenital, 36 (10%) of rheumatic, 49 (13.7%) of syphilitic, 27 (7.5%) of MVP, 69 (19.3%) of ischemic

Echocardiography Tutorial - Mitral Valve
The mitral valve lies between the left atrium and the left ventricle and has two leaflets, the anterior and the posterior. In the figures below, the anterior leaflet is colored green and the posterior leaflet is colored blue. The corresponding video clips show the motion of the valve through the cardiac cycle, but the leaflets are not colored. The images in the left column show the mitral valve directly visualized from the left ventricle, where the chordae tendinae of the subvalvular apparatus can be appreciated. The middle images are taken using transthoracic echocardiography in a 2 chamber, long axis view of the mitral valve. The images on the right are taken of the anterior and posterior leaflets in a short axis view of the heart taken at the level of the mitral valve annulus using transthoracic echocardiography. Applications such as color flow echocardiography allow for the visualization of flow through the mitral valve. Other anatomical features of the mitral valve that can be visualized ...

Introduction: The venturi effect, flow drag effect and abnormal mitral valve apparatus have all been implicated in the development of systolic anterior motion (SAM) of mitral valve among HCM patients. Nevertheless, SAM has also been shown to occur in the absence of HCM or abnormal mitral apparatus. A long posterior mitral leaflet (PML) in relation to the LV cavity may move the coaptation point of the leaflets anteriorly during systole, thus exposing the PML/AML to the flow drag effect of the ejecting blood.. Hypothesis: We hypothesize that a simple mismatch between PML length and LV cavity i.e. a high PML/LV internal diameter in systole (LVIDS) ratio is an important factor for SAM of mitral valve to occur in HCM patient. The null hypothesis is there was no difference in the PML/LVIDS ratio among HCM patients, with or without SAM.. Methods: Consecutive 74 patients who were diagnosed to have HCM with asymmetrical septal hypertrophy(ASH) from our echocardiography laboratories from November 2007 ...

Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets, to inhibit prolapse into the left atrium. At least one marginal chordae is severed, to permit leaflet closure against the band.

Numerical models of the mitral valve have been used to elucidate mitral valve function and mechanics. These models have evolved from simple two-dimensional approximations to complex three-dimensional fully coupled fluid structure interaction models. However, to date these models lack direct one-to-one experimental validation. As computational solvers vary considerably, experimental benchmark data are critically important to ensure model accuracy. In this study, a novel left heart simulator was designed specifically for the validation of numerical mitral valve models. Several distinct experimental techniques were collectively performed to resolve mitral valve geometry and hemodynamics. In particular, micro-computed tomography was used to obtain accurate and high-resolution (39 μm voxel) native valvular anatomy, which included the mitral leaflets, chordae tendinae, and papillary muscles. Three-dimensional echocardiography was used to obtain systolic leaflet geometry. Stereoscopic digital particle ...

Are parallel 10ths ok in 3 part counterpoint? - Music: Practice & Theory Stack ExchangeAre parallel 10ths ok in 3 part counterpoint? - Music: Practice & Theory Stack Exchange
In addition to Aarons answer there are three other things you should maybe consider:. The first chord has no 3rd, only root and fifth. I like it but it would be considered wrong in Bach style counterpoint. It is so long since I have done strict counterpoint I am not going to comment on whether on not it is acceptable in that tradition.. In the second chord you have doubled the 3rd of a major chord if it is intended to be the dominant chord. If you could find a way to avoid this it would probably improve the counterpoint. The absence of the root, if the chord is the dominant, or fifth if the chord is a leading note chord, makes the harmony ambiguous. There again the voice leading to the submediant chord does help to compensate for any harmonic problem but to my ears the doubled leading note is not good. And if it is meant to be a leading note chord it should be in the first inversion.. The other point is that the ninth chord is the mediant chord between two root position dominant chords; within ...
