Anatomical study of truncus arteriousus communis with embryological and surgical considerations. (1/685)

Twelve specimens of truncus arteriosus communis have been studied anatomically, with special reference to the conal anatomy and to the associated cardiac anomalies which can create additional problems if surgical repair is planned. A wide spectrum of conal morphology has been observed, suggesting that differential conal absorption is a developmental characteristic of truncus arteriousus as well as of transposition complexes. The invariable absence of septation of the ventricular infundibula and semilunar valves, in spite of the variable anatomy of the free wall of the conus, indicates that all types of truncus arteriosus, ontogenetically, should be considered as a single undivided conotruncus. Various types of ventircular septal defect were found: (a) ventricular septal defect with absent crista, in which no remnants of conal septum are present; (b) supracristal ventricular septal defect, in which vestigial conal septum is seen in front of the membranous septum; (c) bulloventricular foramen, associated with univentricular origin of the truncus from the right ventricle. Frequent associated anomalies are underdevelopment of the aortic arch, truncal valve malformations, and obstructive ventricular septal defect. The AV conduction system studied in one case showed an arrangement similar to Fallot's tetralogy with the His bundle and the left bundle-branch in a safe position behind the posteroinferior rim of the defect. The postoperative fate of the frequently abnormal truncal valve and the theoretical indications for total repair for Type IV truncus are also discussed.  (+info)

Connexin 43 expression reflects neural crest patterns during cardiovascular development. (2/685)

We used transgenic mice in which the promoter sequence for connexin 43 linked to a lacZ reporter was expressed in neural crest but not myocardial cells to document the pattern of cardiac neural crest cells in the caudal pharyngeal arches and cardiac outflow tract. Expression of lacZ was strikingly similar to that of cardiac neural crest cells in quail-chick chimeras. By using this transgenic mouse line to compare cardiac neural crest involvement in cardiac outflow septation and aortic arch artery development in mouse and chick, we were able to note differences and similarities in their cardiovascular development. Similar to neural crest cells in the chick, lacZ-positive cells formed a sheath around the persisting aortic arch arteries, comprised the aorticopulmonary septation complex, were located at the site of final fusion of the conal cushions, and populated the cardiac ganglia. In quail-chick chimeras generated for this study, neural crest cells entered the outflow tract by two pathways, submyocardially and subendocardially. In the mouse only the subendocardial population of lacZ-positive cells could be seen as the cells entered the outflow tract. In addition lacZ-positive cells completely surrounded the aortic sac prior to septation, while in the chick, neural crest cells were scattered around the aortic sac with the bulk of cells distributed in the bridging portion of the aorticopulmonary septation complex. In the chick, submyocardial populations of neural crest cells assembled on opposite sides of the aortic sac and entered the conotruncal ridges. Even though the aortic sac in the mouse was initially surrounded by lacZ-positive cells, the two outflow vessels that resulted from its septation showed differential lacZ expression. The ascending aorta was invested by lacZ-positive cells while the pulmonary trunk was devoid of lacZ staining. In the chick, both of these vessels were invested by neural crest cells, but the cells arrived secondarily by displacement from the aortic arch arteries during vessel elongation. This may indicate a difference in derivation of the pulmonary trunk in the mouse or a difference in distribution of cardiac neural crest cells. An independent mouse neural crest marker is needed to confirm whether the differences are indeed due to species differences in cardiovascular and/or neural crest development. Nevertheless, with the differences noted, we believe that this mouse model faithfully represents the location of cardiac neural crest cells. The similarities in location of lacZ-expressing cells in the mouse to that of cardiac neural crest cells in the chick suggest that this mouse is a good model for studying mammalian cardiac neural crest and that the mammalian cardiac neural crest performs functions similar to those shown for chick.  (+info)

The presence of infection-related antiphospholipid antibodies in infective endocarditis determines a major risk factor for embolic events. (3/685)

OBJECTIVES: The impact of infection-associated antiphospholipid antibodies (APA) on endothelial cell activation, blood coagulation and fibrinolysis was evaluated in patients with infective endocarditis with and without major embolic events. BACKGROUND: An embolic event is a common and severe complication of infective endocarditis. Despite the fact that APAs are known to be associated with infectious diseases, their pathogenic role in infective endocarditis has not been clearly defined. METHODS: The relationship among the occurrence of major embolic events, echocardiographic vegetation size, endothelial cell activation, thrombin generation, fibrinolysis and APA was examined in 91 patients with definite infective endocarditis, including 26 patients with embolic events and 65 control subjects without embolic events. RESULTS: Overall, 14.3% of patients exhibited elevated APA levels. Embolic events occurred more frequently in patients with elevated levels of APA than in patients without (61.5% vs. 23.1%; p = 0.008). Patients with elevated levels of APA showed higher levels of prothrombin-fragment F1 +2 (p = 0.005), plasminogen-activator inhibitor 1 (p = 0.0002), von Willebrand factor (p = 0.002) and lower levels of activated protein C (p = 0.001) than patients with normal levels of APA. Thrombin generation and endothelial cell activation were both positively correlated with levels of APA. The occurrence of elevated APA levels was frequently associated with structural valve abnormalities (p = 0.01) and vegetations >1.3 cm (p = 0.002). CONCLUSIONS: Infection-associated elevated APA levels in patients with infective endocarditis are related to endothelial cell activation, thrombin generation and impairment of fibrinolysis. This may contribute to the increased risk for major embolic events in these patients.  (+info)

Ineffectiveness of burst suppression therapy in mitigating perioperative cerebrovascular dysfunction. Multicenter Study of Perioperative Ischemia (McSPI) Research Group. (4/685)

BACKGROUND: Cerebral injury is among the most common and disabling complications of open heart surgery. Attempts to provide neuroprotection have yielded conflicting results. We assessed the potential of propofol-induced burst suppression during open heart surgery to provide cerebral protection as determined by postoperative neuropsychologic function. METHODS: Two hundred twenty-five patients undergoing valve surgery were randomized to receive either sufentanil or sufentanil plus propofol titrated to electroencephalographic burst suppression. Blinded investigators performed neurologic and neuropsychologic testing at baseline, postoperative day (POD) 1 (neurologic testing only), PODs 5-7, and PODs 50-70. Neuropsychologic tests were compared with the results of 40 nonsurgical patients matched for age and education. RESULTS: Electroencephalographic burst suppression was successfully achieved in all 109 propofol patients. However, these patients sustained at least as many adverse neurologic outcomes as the 116 controls: POD 1, 40% versus 25%, P = 0.06; PODs 5-7, -18% versus 8%, P = 0.07; PODs 50-70, -6% versus 6%, P = 0.80. No differences in the incidence of neuropsychologic deficits were detected, with 91% of the propofol patients versus 92% of the control patients being impaired at PODs 5-7, decreasing to 52 and 47%, respectively, by PODs 50-70. No significant differences in the severity of neuropsychologic dysfunction, depression, or anxiety were noted. CONCLUSIONS: Electroencephalographic burst suppression surgery with propofol during cardiac valve replacement did not significantly reduce the incidence or severity of neurologic or neuropsychologic dysfunction. The authors' results suggest that neither cerebral metabolic suppression nor reduction in cerebral blood flow reliably provide neuroprotection during open heart surgery. Other therapeutic approaches must be evaluated to address this important medical problem.  (+info)

Viability and enzymatic activity of cryopreserved porcine heart valve. (5/685)

Fibroblast viability of a natural tissue valve for replacing a defective heart valve through allograft or xenograft has been suggested to affect its clinical durability. In this study, the cell viability and enzymatic activity of porcine heart valve leaflets were examined in regard to concerning to the preservation process [variable warm ischemic time (WIT), cold ischemic time (CIT), and cryopreservation]. Porcine heart enblocs were obtained and valve dissection was performed after 2, 12, 24, or 36 hours, in respective groups A, B, C, and D, as WIT. Each group was stored for 24 hours as CIT and cryopreserved. Leaflets were dissected from a valved conduit after each process, and cell viability and enzymatic activity in the leaflet were investigated using trypan blue staining and API ZYM kits. WIT extension significantly decreased fibroblast viability (p < 0.05, 92.25 +/- 2.7% at 2 hours, 84.9 +/- 6.7% at 12 hours, 57.0 +/- 10.2% at 24 hours, 55.9 +/- 7.9% at 36 hours), while CIT for 24 hours was also influenced significantly (p < 0.05), whereas cryopreservation demonstrated no effect on cellular viability. In enzyme activity observation, several enzymes related to lipid or nucleotide degradation (esterase, esterase lipase, particularly phosphatase, phosphohydrolase) were remarkably changed following the valve-fabrication process. After 24 hours CIT, these enzymatic activities in groups B, C and D significantly increased, but the activities decreased after cryopreservation. Particularly, both the viability and enzymatic activity showed remarkable changes after CIT in group B (WIT = 12 hours). These results suggest that WIT is more important than CIT in maintaining viability of the valve, and that completing all the cryopreservation process within 12 hours after acquisition is recommended.  (+info)

Cardiac myosin heavy chains lacking the light chain binding domain cause hypertrophic cardiomyopathy in mice. (6/685)

Myosin is a chemomechanical motor that converts chemical energy into the mechanical work of muscle contraction. More than 40 missense mutations in the cardiac myosin heavy chain (MHC) gene and several mutations in the two myosin light chains cause a dominantly inherited heart disease called familial hypertrophic cardiomyopathy. Very little is known about the biochemical defects in these alleles and how the mutations lead to disease. Because removal of the light chain binding domain in the lever arm of MHC should alter myosin's force transmission but not its catalytic function, we tested the hypothesis that such a mutant MHC would act as a dominant mutation in cardiac muscle. Hearts from transgenic mice expressing this mutant myosin are asymmetrically hypertrophied, with increases in mass primarily restricted to the cardiac anterior wall. Histological examination demonstrates marked cellular hypertrophy, myocyte disorganization, small vessel coronary disease, and severe valvular pathology that included thickening and plaque formation. Skinned myocytes and multicellular preparations from transgenic hearts exhibited decreased Ca2+ sensitivity of tension and decreased relaxation rates after flash photolysis of diazo 2. These experiments demonstrate that alterations in myosin force transmission are sufficient to trigger the development of hypertrophic cardiomyopathy.  (+info)

Oral d,l sotalol reduces the incidence of postoperative atrial fibrillation in coronary artery bypass surgery patients: a randomized, double-blind, placebo-controlled study. (7/685)

OBJECTIVES: The purpose of this prospective, randomized, double-blind, placebo-controlled study was to assess the efficacy of preoperatively and postoperatively administered oral d,l sotalol in preventing the occurrence of postoperative atrial fibrillation (AF). BACKGROUND: Atrial fibrillation is the most common arrhythmia following coronary artery bypass surgery (CABG). Its etiology, prevention and treatment remain highly controversial. Furthermore, its associated morbidity results in a prolongation of the length of hospital stay post-CABG. METHODS: A total of 85 patients, of which 73 were to undergo CABG and 12 CABG plus valvular surgery (ejection fraction > or = 28% and absence of clinical heart failure), were randomized to receive either sotalol (40 patients; mean dose = 190 +/- 43 mg/day) started 24 to 48 h before open heart surgery and continued for four days postoperatively, or placebo (45 patients, mean dose = 176 +/- 32 mg/day). RESULTS: Atrial fibrillation occurred in a total of 22/85 (26%) patients. The incidence of postoperative AF was significantly (p = 0.008) lower in patients on sotalol (12.5%) as compared with placebo (38%). Significant bradycardia/hypotension, necessitating drug withdrawal, occurred in 2 of 40 (5%) patients on sotalol and none in the placebo group (p = 0.2). None of the patients on sotalol developed Torsade de pointes or sustained ventricular arrhythmias. Postoperative mortality was not significantly different in sotalol versus placebo (0% vs. 2%, p = 1.0). Patients in the sotalol group had a nonsignificantly shorter length of hospital stay as compared with placebo (7 +/- 2 days vs. 8 +/- 4 days; p = 0.24). CONCLUSIONS: The administration of sotalol, in dosages ranging from 80 to 120 mg, was associated with a significant decrease (67%) in postoperative AF in patients undergoing CABG without appreciable side effects. Sotalol should be considered for the prevention of postoperative AF in patients undergoing CABG in the absence of heart failure and significant left ventricular dysfunction.  (+info)

Expression of the Mf1 gene in developing mouse hearts: implication in the development of human congenital heart defects. (8/685)

The transcription factor FKHL7 gene has recently been associated with the anterior segment dysgenesis disorder of the eye known as Axenfeld-Rieger anomaly (ARA). A growing body of evidence indicates that mutations in FKHL7 cause not only defects in the anterior segment of the eye but defects in the heart valves and septa as well. In order to evaluate its contribution to normal heart septation and valve formation, expression of the mouse homologue Mf1 in embryonic hearts was analyzed by in situ hybridization. A weak but significant level of Mf1 expression could be detected in the endocardium of mouse embryos as early as day 8.5 post-conception (p.c.). Mf1 expression was undetectable in the hearts of day 9.5 p.c. embryos, but by day 10.5-11 p.c., Mf1 transcripts could be found again in the endocardium of both the atrium and ventricle and a relatively strong signal was observed in the dorsal portion of the septum primum, in what appeared to be the spinal vestibule. At day 13 p.c. when aortic and pulmonary trunks are separated, relatively more Mf1 transcripts were detected in the leaflets of aortic, pulmonary, and venous valves, the ventral portion of the septum primum, as well as in the single layer of cells on the edges of the atrioventricular cushion tissues. Surprisingly, there was no signal detected in the developing interventricular septum. At day 15 p.c., overall Mf1 signals were greatly decreased. However, significant levels of expression could still be observed in the atrial septum, the tricuspid valve, the mitral valve, and in the venous valve but not in the interventricular septum. The temporal and spatial expression patterns of the Mf1 gene in developing mouse hearts suggest that Mf1 may play a critical role in the formation of valves and septa with the exception of the interventricular septum. This is further supported by our studies showing that mutations in the FKHL7 gene were associated with defects in the anterior segment of the eye as well as atrial septal defects or mitral valve defects.

Heart valve surgery is a procedure to treat heart valve disease. In heart valve disease, at least one of the four heart valves that keep blood flowing in the correct direction through your heart doesnt function properly. In heart valve surgery, your surgeon repairs or replaces the affected heart valves.
Our data provide unique insight into the events that support human developmental valvulogenesis. Within this study, we have investigated cellular and molecular processes responsible for human valve maturation and elongation during development. We have identified that human leaflet cell density and proliferation decrease significantly from the first to the second trimester. Differential VEC proliferation patterns were identified in the ventricularis and fibrosa layers. We sought to determine the origin of cells that populate the leaflet mesenchyme during development. We found that VECs undergo EndMT in the cardiac cushions as early as 4 weeks of development, based on inactive cytoplasmic NFATC1 and CD44 expression. Once in the cushions, these cells maintain cytoplasmic NFATC1 expression. Between 5 and 9 weeks of development, we detected strong expression of inactive NFATC1 at the junction of the leaflet/annulus mesenchyme. Later in development (weeks 11 to 17) this expression pattern disappeared ...
Press Release issued Mar 3, 2016: A heart valve is present in arteries and veins and facilitates blood flow only in one direction through the heart. The four major valves in the heart are two atrioventricular valves known as bicuspid valve and tricuspid valve and two semilunar valves known as aortic valve and pulmonary valve. A heart valve separates the atria, ventricles and blood vessels from each other. A heart valve is pushed open to allow blood flow and it closes and prevents backflow of blood. This closing is sealed tightly by nodules present at the tip of the cusps, which are the opening leaflets of the heart valve. The dysfunction of the heart valve causes valvular heart disease. There are two types of valvular heart disease, regurgitation or valvular insufficiency where blood flows in wrong direction due to dysfunctional heart valve and the second is valvular stenosis (Severe Aortic Stenosis) where the heart valve becomes narrow. Injured and defective heart valves are repaired or replaced by

N2 - A disposable injection molded bioreactor for growing tissue-engineered heart valves is controlled to mimic the physiological heart cycle. Tissue-engineered heart valves, cultured from human stem cells, are a possible alternative for replacing failing aortic heart valves, where nowadays biological and mechanical heart valves are used. Growing and conditioning is done by mechanically stimulating the tissue in a bioreactor. The disposable injection molded bioreactor uses flexible membranes and steering valves to mimic a physiological heart cycle. In this work, an air pressure actuation control system for this bioreactor is designed. One membrane is position controlled to achieve a desired flow through the heart valve, while another membrane controls the aortic pressure. A third actuator controls a ...
We analyzed patterning of myocardial AVC differentiation in MZdicer+430 mutant embryos. Nppa (natriuretic peptide precursor type A) is expressed in ventricular and atrial working myocardial cells, whereas bmp4 (bone morphogenetic protein 4) shows a reciprocal expression pattern, restricted to the AVC myocardium. Spatial expression patterns of nppa and bmp4 were unaffected in MZdicer+430 mutants (Online Figure I), demonstrating correct patterning of the myocardium.. Next, we analyzed differentiation of the endocardium. Expression of nfatc1 (nuclear factor of activated T-cells, cytoplasmic, calcineurin-dependent 1) in MZdicer+430 mutant embryos demonstrated the presence of an endocardial lining throughout the heart tube (Online Figure I). Normally, a small population of endocardial cells located at the AVC form ECs, marked by Has2 expression (Figure 1C). Consistent with the increased levels of HA in the cardiac jelly in MZdicer+430 mutants, we found that Has2 expression was no longer restricted to ...
Heart valve diseases are common with an estimated prevalence of 2.5% in the Western world. The number is rising due to an ageing population. Once symptomatic, heart valve diseases are potentially lethal, and heavily influence daily living and quality of life. Surgical treatment, either valve replacement or repair, remains the treatment of choice. However, post surgery, the transition to daily living may become a physical, mental and social challenge. We hypothesise that a comprehensive cardiac rehabilitation programme can improve physical capacity and self-assessed mental health and reduce hospitalisation and healthcare costs after heart valve surgery. A randomised clinical trial, CopenHeartVR, aims to investigate whether cardiac rehabilitation in addition to usual care is superior to treatment as usual after heart valve surgery. The trial will randomly allocate 210 patients, 1:1 intervention to control group, using central randomisation, and blinded outcome assessment and statistical analyses. The
There are two basic types of heart valve defects: a narrowing of a valve (stenosis) and a leak in a valve that allows blood to back up (regurgitation). You might need heart valve surgery if you have one of these defects and its affecting your hearts ability to pump blood.. Your doctor will evaluate you to determine the most appropriate treatment for your condition. If you dont have signs or symptoms, or your condition is mild, your doctor might suggest monitoring over time. In that case, healthy lifestyle changes and medications might help manage symptoms.. Eventually, your valve might need to be repaired or replaced. In some cases, doctors recommend heart valve repair or replacement even if youre not having symptoms. If you need heart surgery for another condition, doctors might repair or replace the affected heart valve at the same time.. Your doctor will discuss with you whether heart valve repair or replacement is more appropriate for your condition. Doctors often recommend heart valve ...

Decellularization of porcine heart valves is the removal of cells along with antigenic cellular elements by either physical or chemical decellularization of the tissue. This decellularized valve tissue provides a scaffold with the remaining extracellular matrix (ECM) that can then be used for tissue engineering and valve replacement in humans inflicted with valvular disease. Decellularized biological valves have potential benefit over conventional valves through decreased calcification which is thought to be an immuno-inflammatory response initiated by the recipient. Valvular disease is caused primarily by valvular lesions stemming from infections, especially rheumatic fever (Streptococceus pyogenes), which can result in either a regurgitant or stenotic valve, or both. Regurgitation results from lesions on the valve edges or annular dilation which causes backwards-flow of the blood. Stenosis results in thickened leaflets due to heavy fibrosis of the valve so blood cannot flow through normally . ...

ROCKVILLE, Md. -- The FDA has approved the first prosthetic heart valve made from decellularized human tissue as a replacement for a diseased or damaged pulmonary valve.
Bovine heart valves metabolize up to 96% of exogenous |sup|14|/sup|C-glucose to lactate when incubated in vitro under appropriate conditions. Small proportions of the |sup|14|/sup|C-radioactivity are incorporated into glycogen, glycosaminoglycans and lipids and are oxydized to |sup|14|/sup|CO|sub|2|/sub|. Difference between the valves of the left ventricle (aortic and mitral valve) and of the right ventricle (pulmonary and tricuspid valve) were found in the rate of glycolysis as well as in the collagen, glycogen and glycosaminoglycan content. The in vitro incorporation of [U-|sup|14|/sup|C] glucose radioactivity into the total glycosaminoglycans resulted in a specific labelling of hyaluronic acid, dermatan sulfate and chondroitin sulfate, but the specific radioactivities of the individual glycosaminoglycans and their relative rates of biosynthesis differed markedly. The relative rates of biosynthesis were 2.9-7.6 for hyaluronate, 1.0 for dermatan sulfate and 0.26-0.59 for chondroitin sulfate. After

Introduction: Minimally invasive valve replacement procedures rapidly evolve as alternative treatment option for patients with valvular heart disease. Based on non-living bioprosthetic materials, currently used valve protheses are associated with disadvantages i.e. degenerative dysfunction. Tissue engineering (TE) technologies providing living, autologous heart valves with the capacity of regeneration and growth have shown functionality in long-term animal studies and initial human applications. Here, we introduce a novel strategy combining two promising heart valve technologies: minimally invasive replacement and tissue engineering.. Methods: Trileaflet heart valves (n=8, 30mm) based on rapidly degrading polymer scaffolds and self-expandable stents were engineered from ovine autologous vascular-derived cells. Valves were grown in-vitro for 12d utilizing diastolic loading bioreactor systems. Thereafter, the valves were crimped applying a novel introduction system (12mm). 4 valves were delivered ...

Although we previously reported that an angioinhibitory factor chondromodulin I maintains cardiac valvular function by preventing angiogenesis (Nat Med, 2006), the mechanism underlying the progression of degenerative valvular heart disease (VHD) is poorly understood, and no preventive therapy has been established. Periostin is reported to be a stress-responsive, secreted protein that promotes embryonic cardiac valve development, but its physiological and pathophysiological roles in VHD remain unknown. We investigated the possible involvement of periostin in VHD, and if it is involved, how it affects the progression of VHD.. Methods and Results: ...
A device for improving the function of a heart valve has a first and a second shape. The device comprises two contact points, wherein the device in the first shape exhibits a distance between the two contact points essentially corresponding to a distance between two commissures of the heart valve and the device in the second shape exhibits an increased distance between the contact points. The device is in the first shape arranged for insertion to the heart valve to establish a contact between the contact points and the commissures. The device is transferable from said first shape to said second shape, and the device is in the second shape arranged for extending in abutment with valve tissue throughout a cycle of heart action. The device may change the shape of the heart valve by stretching it between the commissures for improving the ability of the heart valve to close.
The best treatment for you will depend on your age, your general health and the severity of your heart condition. Some heart valve problems respond well to lifestyle changes and medications. When medical management is not enough to manage your heart valve condition, your heart specialist may recommend a valve repair or replacement. It may be possible to surgically correct defects in the valve. However, if the heart valves are too badly damaged to be successfully repaired, valve replacement is an option. Replacement heart valves may be either mechanical (metal and plastic) or bioprosthetic (from human donors or animals). ...
Youll likely begin to feel better almost right away. Your condition will improve gradually, and youll notice that each day youll feel a little bit better. However, youll have to make some lifestyle adjustments to get the most out of your new or repaired heart valve.. There are precautions you should take to make sure your heart valve disease does not return. Make sure to visit your doctor for follow-up care. He or she will give you instructions on how and when to take your medicine and about activities you can do and which ones to avoid.. Having a heart valve repaired may cause you to think that you need to greatly change your lifestyle. You will probably feel much better physically with continued improvement several weeks or months after your surgery. As you feel better, you may want to discuss some of this information further with your doctor.. ...
This invention discloses a percutaneous delivered heart valve and delivery means thereof, wherein the percutaneous delivered heart valve is a twistedly foldable heart valve prosthesis comprising a generally cylindrical support element with a diameter, wherein the support element is twistedly foldable to a smaller diameter, a flexible heart valve with a plurality of valvular leaflets releasably attached to said support element, and a receptacle having a plurality of connecting members secured to the cylindrical support element, wherein the receptacle is releasably matched to an expanding element capable of untwisting the receptacle adapted for un-twisting and unfolding said heart valve.
An apparatus and method are disclosed for supporting a heart valve with a flexible girdle. The girdle has an elongated cylindrical sidewall having an axial length at least commensurate with the heart valve. The girdle is disposed around a tubular valve wall of the heart valve being implanted so that the inflow end of the girdle is adjacent the inflow end of the tubular valve wall. The inflow ends of the girdle and heart valve may then be sutured together to implant the valve. The girdle provides support to stabilize the heart valve and inhibit deformation thereof.
At times, one or more valves do not close or open properly and this leads to disruptions in the blood flow from heart to body. Such a condition is called heart valve disease and the treatment of the condition is dependent on the severity and type of the disease and the heart valve that is damaged. Atresia, stenosis, and regurgitation are the basic issues of heart valves. Disease of heart valves can be present at the time or birth or it can also develop in later stages of life or in adulthood because of several conditions and causes, such as other types of heart conditions and infections ...

Middle-aged heart valve replacement patients may have better outcomes if they receive valves made from animal tissue rather than metal, researchers report.. The investigators analyzed 13 studies that compared metal and tissue valves in patients aged 40 to 70 who had aortic valve replacement.. Heart valves are designed to allow blood to flow in only one direction through the heart.. The two types of valves studied have different risks and benefits, the authors of the report explained.. Metal (mechanical) valves last longer but are more likely to cause blood clots. So patients have to take blood-thinning drugs for the rest of their lives, which can increase the risk of major bleeding, the study authors said.. Tissue (bioprosthetic) valves are less likely to cause blood clots, but they may need to be replaced at some point, the authors added.. Fifteen years after receiving new heart valves, there were no differences in rates of survival, stroke or infection of the heart lining between the two ...

In vertebrates, heart pumping is required for cardiac morphogenesis and altering myocardial contractility leads to abnormal intracardiac flow forces and valve defects. Among the different mechanical cues generated in the developing heart, oscillatory flow has been proposed to be an essential factor in instructing endocardial cell fate toward valvulogenesis and leads to the expression of klf2a, a known atheroprotective transcription factor. To date, the mechanism by which flow forces are sensed by endocardial cells is not well understood. At the onset of valve formation, oscillatory flows alter the spectrum of the generated wall shear stress (WSS), a key mechanical input sensed by endothelial cells. Here, we establish that mechanosensitive channels are activated in response to oscillatory flow and directly affect valvulogenesis by modulating the endocardial cell response. By combining live imaging and mathematical modeling, we quantify the oscillatory content of the WSS during valve development ...
Abstract A computational structural deterministic modeling strategy has been developed and experimentally validated to (1) assist tissue engineering scaffold fabrication, and as a consequence to improve in vivo scaffolds performances, and (2) provide a better understanding of cellular mechanical and metabolic response to local micro-structural deformations of the extracellular matrix (ECM). Image analysis software was developed and tested on electrospun poly (ester urethane) urea (PEUU) scaffolds, collagen gels, decellularized tissues. The algorithm analyzed SEM and multi-photon images (maximum imaging penetration depth: 160 µm) providing a full 3D characterization of engineered constructs morphology (n ≥ 6). The detected material topologies were adopted to generate statistically equivalent scaffold biomechanical models minimizing the difference between the real material and network model architectural features. The mechanical response at the macro scale was fully characterized by stress control

Computer simulation of the beating human heart requires the simultaneous solution of equations of motion that couple together the fluid mechanics of the blood, the elasticity of the flexible heart valve leaflets, and the active, time-dependent elasticity of the muscular heart walls. The immersed boundary (IB) method was created to solve this problem. It regards the cardiac tissue as a part of the fluid in which additional, elastic forces are applied. These forces are generated by a collection of immersed elastic fibers that model the muscle fibers of the heart walls and the collagen fibers that give the heart valve leaflets their strength. Results will be shown as a computer animation of the beating heart. Not included in these simulations is the electrical activity that coordinates and controls the heartbeat, but we shall discuss how the IB framework can be generalized to solve the electrical problem, too. ...

What Are Diseased Heart Valves?. Diseased heart valves can affect the flow of blood through the heart. The heart consists of four valves, with two large blood vessels leaving the heart to ensure that blood doesnt go back into the heart after it has been pumped out.. Diseased or damaged heart valves can affect this flow by restricting or obstructing the blood-this is known as valve stenosis or narrowing. This puts extra strain on the heart so that it has to pump much harder to get the blood through the narrowing. If the valve doesnt close properly, then its known as a leaky valve, valve incompetence, or regurgitation.. What Causes Diseased Heart Valves?. There are a few known causes, and these include being born with an abnormal valve/s, having had rheumatic fever, damaged heart muscle after a heart attack, or cardiomyopathy (a disease of the heart muscle). If youve had rheumatic fever or a previous condition with endocarditis, these can all have an effect.. One of the main causes of diseased ...
