Bioprosthesis
Prosthesis, usually heart valve, composed of biological material and whose durability depends upon the stability of the material after pretreatment, rather than regeneration by host cell ingrowth. Durability is achieved 1, mechanically by the interposition of a cloth, usually polytetrafluoroethylene, between the host and the graft, and 2, chemically by stabilization of the tissue by intermolecular linking, usually with glutaraldehyde, after removal of antigenic components, or the use of reconstituted and restructured biopolymers.
Heart Valve Prosthesis
A device that substitutes for a heart valve. It may be composed of biological material (BIOPROSTHESIS) and/or synthetic material.
Heart Valve Prosthesis Implantation
Surgical insertion of synthetic material to repair injured or diseased heart valves.
Aortic Valve
The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.
Tricuspid Valve Stenosis

Pericardium
A conical fibro-serous sac surrounding the HEART and the roots of the great vessels (AORTA; VENAE CAVAE; PULMONARY ARTERY). Pericardium consists of two sacs: the outer fibrous pericardium and the inner serous pericardium. The latter consists of an outer parietal layer facing the fibrous pericardium, and an inner visceral layer (epicardium) resting next to the heart, and a pericardial cavity between these two layers.
Cardiac Catheterization

Destructive aortic valve endocarditis from Brucella abortus: survival with emergency aortic valve replacement. (1/643)

Brucella abortus infection of the aortic valve caused acute aortic regurgitation leading to severe left ventricular failure in a 62-year-old man. He made an excellent recovery after emergency aortic valve replacement. This is the third reported case of successful heart valve replacement for Brucella endocarditis and the second such case involving the aortic valve.  (+info)

Long-term survival and valve-related complications in young women with cardiac valve replacements. (2/643)

BACKGROUND: The type of cardiac valve replacement associated with the lowest health risks for young women who may undergo pregnancies is unknown. We investigated which valve type was associated with greatest patient and valve survival and the effect of pregnancy on valve loss. METHODS AND RESULTS: In this retrospective study, all women 12 to 35 years old who underwent valve replacements between 1972 and 1992 at Greenlane Hospital were identified, and follow-up was available in 93%. The 232 women were followed up for 1499 patient-years. Ten-year survival of women with mechanical (n=178), bioprosthetic (n=73), and homograft (n=72) valves was 70% (95% CI, 59% to 83%), 84% (95% CI, 72% to 99%), and 96% (95% CI, 91% to 100%), P=0.002. After adjustment for confounding variables, the relative risk (RR) of death with mechanical compared with bioprosthetic valves was 2.17 (95% CI, 0.78 to 5.88). Thromboembolic events occurred in 45% of women with mechanical valves within 5 years, compared with 13% with bioprosthetic valves, P=0.0001. Valve loss at 10 years was higher in bioprosthetic valves [82% (95% CI, 62% to 92%)] than in mechanical [29% (95% CI, 17% to 39%)] or homograft [28% (95% CI, 12% to 41%)] valves, P=0.0001. Pregnancy was not associated with increased bioprosthetic (RR, 0.96; 95% CI, 0.68 to 1. 35), homograft (RR, 0.65; 95% CI, 0.37 to 1.13), or mechanical (RR, 0.54; 95% CI, 0.27 to 1.08) valve loss. CONCLUSIONS: Although 10-year valve survival was greater with mechanical than bioprosthetic valves, mechanical valves may be associated with reduced patient survival in young women. Thromboembolic complications, often with long-term sequelae, were common with mechanical valves. Pregnancy did not increase structural deterioration or reduce survival of bioprosthetic valves.  (+info)

Haemodynamic performance of aortic pericardial bioprostheses and bileaflet prostheses at rest and during exercise: implications for the surgical management of patients with small aortic roots. (3/643)

OBJECTIVE: To determine the haemodynamic behaviour, at rest and during exercise, of aortic valve pericardial bioprostheses and different sizes of bileaflet prosthesis. DESIGN: Observational study. SETTING: Tertiary medical centre. PATIENTS AND INTERVENTIONS: 74 patients (33 women, 41 men; mean age 64 years) in whom 40 pericardial bioprostheses and 34 bileaflet prostheses sized 19, 21, or 23 mm had been implanted to replace aortic valves. MAIN OUTCOME MEASURES: Doppler echocardiography at rest and at peak exercise, between 12 and 47 months after surgery. RESULTS: All patients achieved a significant increase in heart rate, systolic blood pressure, and cardiac output with exercise. Transvalvar pressure fall, valve area, and left ventricular systolic and diastolic function indices also underwent significant changes with exercise. Reductions in peak and mean transvalvar pressure, at rest and at peak exercise, were greater in patients with small valves (p < 0.05). Valve areas and effective area index were greater in the patients with larger valves (p < 0.001). There were no significant differences between patients with mechanical and biological prostheses with regard to transvalvar pressure fall and valve areas at rest and at peak exercise. CONCLUSIONS: 19 mm and 21 mm aortic prostheses and bioprostheses continue to create significant obstruction, particularly with exercise.  (+info)

The use of a stentless porcine bioprosthesis to repair an ascending aortic aneurysm in combination with aortic valve regurgitation. (4/643)

Over the years, many surgical methods have evolved for the treatment of ascending aortic aneurysm in combination with aortic valve regurgitation; however, precise guidelines for optimal surgical techniques for varying presentations have not been defined. We describe the use of a stentless porcine bioprosthesis (Medtronic Freestyle) in a patient with an ascending aortic aneurysm and aortic regurgitation. We used the complete root replacement method, and anastomosed a Dacron graft (Hemashield) between the bioprosthetic valve and the native aorta to replace the distal part of the aneurysm.  (+info)

Hemodynamic and physical performance during maximal exercise in patients with an aortic bioprosthetic valve: comparison of stentless versus stented bioprostheses. (5/643)

OBJECTIVES: The objective of this study was to compare stentless bioprostheses with stented bioprostheses with regard to their hemodynamic behavior during exercise. BACKGROUND: Stentless aortic bioprostheses have better hemodynamic performances at rest than stented bioprostheses, but very few comparisons were performed during exercise. METHODS: Thirty-eight patients with normally functioning stentless (n = 19) or stented (n = 19) bioprostheses were submitted to a maximal ramp upright bicycle exercise test. Valve effective orifice area and mean transvalvular pressure gradient at rest and during peak exercise were successfully measured using Doppler echocardiography in 30 of the 38 patients. RESULTS: At peak exercise, the mean gradient increased significantly less in stentless than in stented bioprostheses (+5 +/- 3 vs. +12 +/- 8 mm Hg; p = 0.002) despite similar increases in mean flow rates (+137 +/- 58 vs. +125 +/- 65 ml/s; p = 0.58); valve area also increased but with no significant difference between groups. Despite this hemodynamic difference, exercise capacity was not significantly different, but left ventricular (LV) mass and function were closer to normal in stentless bioprostheses. Overall, there was a strong inverse relation between the mean gradient during peak exercise and the indexed valve area at rest (r = 0.90). CONCLUSIONS: Hemodynamics during exercise are better in stentless than stented bioprostheses due to the larger resting indexed valve area of stentless bioprostheses. This is associated with beneficial effects with regard to LV mass and function. The relation found between the resting indexed valve area and the gradient during exercise can be used to project the hemodynamic behavior of these bioprostheses at the time of operation. It should thus be useful to select the optimal prosthesis given the patient's body surface area and level of physical activity.  (+info)

Valve replacement for aortic stenosis in patients with poor left ventricular function: comparison of early changes with stented and stentless valves. (6/643)

BACKGROUND: Long-standing aortic stenosis causes significant left ventricular (LV) dysfunction, which may progress irreversibly. In many cases, LV function can be salvaged by aortic valve surgery, although debate exists regarding the best valve prosthesis to use. METHODS AND RESULTS: We studied 33 patients retrospectively who had significant aortic stenosis and impaired LV systolic function, as assessed by transthoracic Doppler echocardiography. Patients were assessed preoperatively and before discharge from the hospital. A total of 20 patients received a stentless (homograft or Toronto) valve, and 13, a stented valve. No patient had significant aortic regurgitation or other valvular disease. Preoperatively, fractional shortening was 18.8+/-5.5% in the stentless group and 18.6+/-3.8% in the stented group. Postoperatively, it was 25.6+/-6.9% (P<0.001 compared with baseline) and 17.0+/-2.8%, respectively (P<0.001 compared with stentless group). Fractional shortening improved because of a reduction in LV end-systolic and end-diastolic dimensions in the stentless group. Systolic long axis function at the LV free wall also recovered, with an increase in systolic excursion and both peak shortening and lengthening rates. No change was noted in mitral valve Doppler patterns. CONCLUSIONS: Patients who received a stentless valve demonstrated a significantly greater early improvement in LV systolic function compared with those who received a stented valve.  (+info)

Prospectively randomized evaluation of stentless versus conventional biological aortic valves: impact on early regression of left ventricular hypertrophy. (7/643)

BACKGROUND: The aim of this prospectively randomized study was to evaluate left ventricular hypertrophy and its regression after stentless versus conventional biological aortic valve replacement. METHODS AND RESULTS: From March 1996 through April 1998, 180 patients were prospectively selected; 106 patients received a stentless aortic valve (SAV), and 74 received a conventional stented bioprosthesis (CSB). Of these patients, 95% and 96%, respectively, had aortic stenosis. Their mean age was 72.3 and 74.8 years, and there were no significant differences in left ventricular function, preoperative pressure gradients, and NYHA functional status. Aortic annulus diameter indexes were comparable at 13.46 (SAV) versus 13.55 (CSB) mm (P=NS). Larger SAVs were implanted because of the oversizing technique. In-hospital mortality (n=3 and 1 for SAV and CSB) was not valve related. At follow-up, all patients were in NYHA class 1 or 2. Baseline end-diastolic left ventricular posterior wall thickness was 15.6 (SAV) and 14.8(CSB) mm (P=NS) and decreased to 11. 8 (SAV) and 13.2 (CSB) mm (P<0.05) at 6 months. Left ventricular mass index was 213 and 202 g/m(2) at baseline (P=NS), whereas after 6 months, it was 141 (SAV) and 170 (CSB) g/m(2) (P<0.05). CONCLUSIONS: Regression of left ventricular hypertrophy occurs in all patients after aortic valve replacement but is significantly enhanced after SAV implantation. This possibly is due to improved transvalvular hemodynamics.  (+info)

Mid-term comparative follow-up after aortic valve replacement with Carpentier-Edwards and Pericarbon pericardial prostheses. (8/643)

BACKGROUND: The first generation of pericardial valves had a high rate of premature deterioration. The aim of this study was to compare the outcome after aortic valve replacement with second generation pericardial prostheses (Pericarbon and Carpentier-Edwards). METHODS AND RESULTS: Between 1987 and 1994, 162 patients underwent aortic valve replacement with either a Pericarbon (n=81, 69+/-11 years) or a Carpentier-Edwards (n=81, 70+/-11 years) pericardial prosthesis. Mean follow-up was 4.4+/-2.7 years for Pericarbon and 4.8+/-2.4 years for Carpentier-Edwards valves (P=0. 27), giving a total follow-up of 745 patient-years. Thirty-day mortality and 5-year actuarial survival were, respectively, 6.2% and 63.2+/-5.7% in the Pericarbon group and 6.2% and 63.5+/-5.6% in the Carpentier-Edwards group. At 8 years, freedom from (and linearized rates per patient-year) thromboembolism, structural failure, and all valve-related events were, respectively, 91.8+/-3.6% (1.4%), 76. 9+/-8.7% (2.5%), and 58.4+/-9.3% (5.6%) in the Pericarbon group and 94.4+/-2.7% (1%), 100% (0%, P<0.01), and 88.8+/-3.7% (2%, P<0.05) in the Carpentier-Edwards group. There were 9 (11.1%) Pericarbon structural failures related predominantly to severe calcification and stenosis. The actual reoperation rate was 7.4% (1.6% per patient-year) in the Pericarbon group for fibrocalcific degeneration (n=3), periprosthetic leak (n=1), endocarditis (n=1), and aortic dissection (n=1). There was neither structural valve failure nor valve reoperation in the Carpentier-Edwards group. Echocardiographic review of 70 patients from 85 survivors (82.3%) found 4 additional Pericarbon valves with signs of early structural failure but no Carpentier-Edwards valve with such changes. CONCLUSIONS: Eight years after aortic valve replacement, Pericarbon pericardial prostheses compared unfavorably with Carpentier-Edwards pericardial prostheses, with a high incidence of structural valve failure and reoperation.  (+info)

Bioprosthesis has been increasingly implanted for the treatment of transvalvular disease across the world. A new Dafodil™ pericardial bioprosthesis (Meril Life Sciences Pvt. Ltd., India) recently approved by Conformité Européenne (CE) is a tri-leaflet, stented, bovine valve. The purpose of Dafodil-1 first-in-human trial was to evaluate clinical safety and performance (including hemodynamic parameters) of the Dafodil pericardial bioprosthesis in patients who underwent aortic or mitral valve replacement. This prospective, multicenter clinical trial enrolled 60 patients (Aortic: 30 patients; Mitral: 30 patients) from seven sites across India. Safety endpoints were early (≤30 days) and late (| 30 days) mortality and valve-related morbidity. The performance endpoints were hemodynamic performance, improvement in NYHA functional class, and change in the quality of life using SF-12v1 health survey. From July 2017 to July 2018, 60 patients underwent implantation of the Dafodil pericardial bioprosthesis.

A 76-year old man with a torn Freedom SOLO bioprosthesis : Interactive CardioVascular and Thoracic Surgery - oi
We describe a case of a 76-year old male who presented with progressive dyspnoea. He underwent an aortic valve replacement with a Freedom SOLO bioprosthesis 6 years ago. Transthoracic echocardiography showed a moderate-to-severe leakage of the Freedom SOLO bioprosthesis. During surgical reintervention, a partial tear of the left coronary cusp was seen from the commissure of the right coronary cusp to its base. After radiographic and microscopic examination, no clear cause was found for the failure of this Freedom SOLO bioprosthesis. To our knowledge, this is the third failure of a Freedom SOLO bioprosthesis reported in the literature. When the long-term follow-up of the Freedom SOLO bioprosthesis is available, it has to be compared with other bioprosthesis for long-term durability. ...

N2 - Leaflet immobility and valve thrombosis have been reported with both transcatheter and surgical aortic valve bioprostheses. The relationships between these abnormalities and their incidence, time course, clinical significance, predisposing factors, optimal imaging modality, and current therapeutic options remain uncertain but are rapidly evolving. Four-dimensional computerized tomographic imaging has been determined to have the highest sensitivity in studies evaluating leaflet immobility and valve thrombosis. Echocardiography is also used during surveillance, but it appears to be less sensitive. The definitive diagnosis of valve thrombosis is based on a combination of diagnostic 4-dimensional computerized tomographic imaging findings, resolution of imaging abnormalities, and elevated transcatheter gradients with anticoagulation or ...

Title:Prevention of Bioprosthetic Heart Valve Calcification: Strategies and Outcomes. VOLUME: 21 ISSUE: 22. Author(s):L.P. Bre, R. McCarthy and W. Wang. Affiliation:Network of Excellence for Functional Biomaterials (NFB), National University of Ireland, Galway, IDA Business Park, Dangan, Galway, Ireland.. Keywords:Anticalcification, bioprosthesis, crosslinking, glutaraldehyde, heart valve replacement, mineralization.. Abstract:Despite the significant advances in cardiac surgery, heart valve replacement still faces a dilemma. While mechanical valves offer lifelong durability they also commit patients to anticoagulation treatment for the rest of their life. On the other hand, bioprosthetic valves have superior hemodynamic performance but durability of the bioprosthesis limits their use to the elderly, with early onset calcification being the primary cause of biomaterial breakdown. Considering that bioprosthetic valves are not reliant upon anticoagulation, there has been much focus on measures to ...

Early Structural Valve Deterioration of the Mitroflow Aortic Bioprosthesis | CirculationEarly Structural Valve Deterioration of the Mitroflow Aortic Bioprosthesis | Circulation
There has been a trend toward more frequent use of bioprosthetic valves, especially in the young generations, over the last decade.1,2 According to the Society of Thoracic Surgeons database, use of bioprosthetic valve increased from 44% in 1996 to 78% in 2006 in North America.1 Freedom from warfarin use and restrictions on diet and activities make bioprosthetic valves more attractive and popular, and multiple reports have shown that choosing a bioprosthetic valve does not decrease survival despite the increased rate of reoperation.3,4. Article see p 2012. The Mitroflow aortic prosthesis (Sorin Group Inc) is one of the most frequently used bioprostheses, with ,100 000 implanted worldwide.5 The bovine pericardium is mounted externally around the stent, which maximizes the flow relative to the stent size. The valve is placed in the supra-annular position compared with the intra-annular position in some of the other bioprostheses. These characteristics allow superior valve hemodynamics in the ...

Several studies have recognized the high prognostic relevance of achieving an optimal hemodynamic result after aortic valve replacement (1-3,13-16). The presence of severe PPM has been associated with lesser improvement in the functional capacity of the patients (13), lesser regression of LV hypertrophy (14), higher rates of cardiac failure (16), and higher rates of perioperative and long-term mortality (2,3,15,16) after SAVR. The Magna and Freestyle valves are among the most commonly used stented and stentless bioprostheses for SAVR, and the results of valve hemodynamic performance observed in the present study for these 2 types of bioprosthesis were consistent with those of previous studies (17-20), although the aortic annulus and bioprosthesis size were smaller in the present study. Previous studies have also reported that the hemodynamic performance of stentless bioprostheses is generally superior, and accordingly, the prevalence/severity of PPM is lower compared with stented bioprostheses ...

Since the first implant in September 1982, the Medtronic Hancock® II has provided more than 20 years of excellent hemodynamic performance and durability. Design improvements over the past generations include: low profile, flexible stent, Supra-X™ supra-annular placement, T6 anti-calcification tissue treatment, modified fixation process, CINCH® advanced implant system and ULTRA™ minimized sewing ring. Valve sizing is a critical consideration in obtaining optimal hemodynamic performance. This is particular true in small aortic roots. A critical issue is the size of the prosthesis in relation to the patients annulus.. The objective of this clinical study is to evaluate, at six and twelve months, the hemodynamic performance of the HancockÒ Ultra™ bioprosthesis in the aortic position, to analyze the incidence of patient prosthesis mismatch, correlation of gradients, and to ascertain frequency at which a larger valve size is used vs. a patients debrided annulus diameter. ...

A bioprosthetic heart valve comprising leaflets with free edges which do not impinge on adjacent leaflets when the leaflets are closed before being implanted and subject to body fluids and cardiac pressure cycles. Commissures supporting the leaflets have semi-permeable membranes which reduce the pressure load on the leaflets during implantation. In response to immersion in body fluids, the membranes become substantially impermeable. The leaflets can stretch in response to loads and hydration, so that the free edges mate shortly after implantation. First and second mechanisms for supporting leaflets to provide multiple effective spring constants. An inner frame supporting commissures of the valve is elastic, permitting the commissures to bend in toward the center of the prosthetic heart valve at very low loads. A relatively rigid annular support ring supports the elastic frame and provides the second spring constant mechanism. The leaflets have an uncoupled mating edge where the leaflet approach each

US7967138B2 - Packaging systems for percutaneously deliverable bioprosthetic valves - Google Patents
A packaging system is disclosed for shipping a prosthetic tissue valve in a storage solution and preparing and loading of the bioprosthetic valve onto a catheter-based delivery system. The packaging system includes a fluid tight container filled with the storage solution attached to a delivery catheter, wherein the container surrounds the prosthetic tissue valve that is in a pre-loaded position on the delivery catheter during shipment and storage. The prosthetic tissue valve may include an attachment mechanism that attaches to the delivery catheter to properly position the tissue valve for loading within the delivery catheter. In another embodiment where the prosthetic tissue valve is not attached to the delivery catheter during shipment, the attachment mechanism may interact with the prosthetic tissue valve shipping container to prevent the bioprosthetic valve from moving during shipment.

New Findings on Bioprosthetic Valve Thrombosis Have Implications for Surveillance, Research | tctmd.comNew Findings on Bioprosthetic Valve Thrombosis Have Implications for Surveillance, Research | tctmd.com
Bioprosthetic valve thrombosis (BPVT) can occur several years after implantation but much earlier than degeneration, stress Sorin V. Pislaru, MD, PhD, and colleagues. The good news, they say, is that cases-once diagnosed-respond well to vitamin K antagonist (VKA) therapy.. The findings are being published in the December 1, 2015, issue of the Journal of the American College of Cardiology.. Raj R. Makkar, MD, of Cedars-Sinai Heart Institute (Los Angeles, CA), lead author of the NEJM paper, told TCTMD in a telephone interview: Clearly weve underappreciated the importance of leaflet thrombosis on structural valve failure, and in a subset of patients this may be the mechanism.. No prospective RCTs have tested the value of anticoagulation in patients with bioprosthetic valves, and studies on both surgical and transcatheter valves would be important, he noted.. Makkar said awareness of these issues is growing in the TAVR field. I think people are serious and people are interested. Everybody ...

Transcatheter Aortic Valve Replacement for Degenerative Bioprosthetic Surgical ValvesClinical Perspective | CirculationTranscatheter Aortic Valve Replacement for Degenerative Bioprosthetic Surgical ValvesClinical Perspective | Circulation
The VIV procedure is technically demanding and should be reserved for highly experienced centers. Operators should be skilled in the handling of device malposition, retrieval techniques, and implantation of a second TAVR device, if needed. During screening, the Heart Team must have all of the information about and be familiar with the particular characteristics of the surgical bioprosthesis: the mode of degeneration and echocardiographic parameters (isolated paravalvular regurgitation should be excluded); valve size (most importantly, bioprosthesis internal diameter should be used for TAVR device and size selection; because of better hemodynamic results, CoreValve may be preferred in cases of small bioprosthesis with internal diameter ,20 mm); valve position (intra-annular versus supra-annular); valve type (stented versus stentless); the relation of the bioprosthetic valve to its radio-opaque markers; and the risk for coronary obstruction when VIV is performed inside that specific ...

Successful Transapical Transcatheter Valve Implantation Within a Dysfunctional Mitral Bioprosthesis | JACC: Cardiovascular...Successful Transapical Transcatheter Valve Implantation Within a Dysfunctional Mitral Bioprosthesis | JACC: Cardiovascular...
The valve-in-valve concept is an emerging therapeutic option for patients with degenerative failure of previously implanted xenografts. Reoperation of degenerated bioprostheses has a high mortality risk that increases with the age and associated comorbidities of the patients. The transcatheter valve-in-valve implantation does not need resternotomy or cardiopulmonary bypass, potentially reducing the morbidity and mortality risk. However, unlike the transcatheter implants in native valves, in the valve-in-valve procedures, the leaflets and calcified annulus are replaced with the rigid annulus of the xenograft. This requires accurate sizing of the transcatheter valve, currently available in 2 sizes. Therefore, 3-dimensional imaging techniques, particularly multi-detector row computed tomography (MDCT), may provide a more exact sizing of the host xenograft ring. We report a mitral valve-in-valve procedure in a 79-year-old female patient with previous aortic and mitral valve replacement (a 21-mm and ...

Bioprosthetic valves are increasingly used in preference to mechanical valves in open SAVR, as lifelong oral anticoagulation is not required and its attendant complications can be avoided. A recent study has shown similar long-term survival rates in patients with bioprosthetic and mechanical valves. However, patients with bioprosthetic valves require reoperations due to their limited durability and expected degeneration;(12) those undergoing such reoperations face increased surgical risk due to their more advanced age (compared with their age during the index SAVR) during the redo surgery and scarring in the non-virgin chest. Consequently, valve-in-valve TAVI appears to be an attractive, minimally invasive method of replacing the degenerated surgical aortic bioprosthesis without the need for a reoperation. Several small case series and a global registry have shown that it is a feasible and viable option for patients at high risk.(5-9). In our initial Asian experience of valve-in-valve TAVI in ...

Methods and results Preoperative echocardiography and dobutamine stress echocardiography at 1 year postoperatively were undertaken in 106 patients (n=18-24 from each group). Stentless bioprostheses, whether porcine or bovine, displayed superior haemodynamics across nearly all echocardiographic parameters: lower gradients, larger effective orifice area, higher dimensionless severity index (DSI) and lower resistance, when compared with stented or mechanical prostheses. Comparing both stented designs, bovine tissue performed the worst at rest, but with stress, there was no difference. The stress performances of the stentless bioprostheses were similar to the mildly stenosed native aortic valve, whereas the performances of the stented and mechanical prostheses resembled that of native valves with mild-to-moderate stenoses. Haemodynamic differences, however, did not translate into differences in left ventricular mass reduction at 1 year.. ...

Aortic Valve Replacement in Children and Young Adults | JACC: Journal of the American College of CardiologyAortic Valve Replacement in Children and Young Adults | JACC: Journal of the American College of Cardiology
The perfect heart valve substitute has not yet been developed and matching the patient to existing options to optimize survival and reduce valve-related complications remains challenging. The choices for aortic valve replacement (AVR) are mechanical valves, bioprosthetic valves, and biological valves such as aortic valve homograft and the Ross procedure (pulmonary autograft). The latter is a complex operation because it transfers the patients own pulmonary valve into the aortic position and uses a biological valve to replace the pulmonary valve, transforming a single-valve disease into a 2-valve disease. These considerations are not important to most North American patients who undergo AVR because they are older and the durability of bioprosthetic valves in this age group is excellent (1,2). The risk of bioprosthetic valve failure 20 years after AVR is ,10% in patients 70 years of age and older (1,2). A report based on the Society of Thoracic Surgeons Database from January 1997 to December 2006 ...

Bioprosthetic Valve - New Heart ValveBioprosthetic Valve - New Heart Valve
The Edwards SAPIEN 3 and SAPIEN 3 Ultra Transcatheter Heart Valve system is indicated for relief of aortic stenosis in patients with symptomatic heart disease due to severe native calcific aortic stenosis who are judged by a Heart Team, including a cardiac surgeon, to be appropriate for the transcatheter heart valve replacement therapy.. The Edwards SAPIEN 3 and SAPIEN 3 Ultra Transcatheter Heart Valve system is indicated for patients with symptomatic heart disease due to failing (stenosed, insufficient, or combined) of a surgical or transcatheter bioprosthetic aortic valve or surgical bioprosthetic mitral valve who are judged by a heart team, including a cardiac surgeon, to be at high or greater risk for open surgical therapy (i.e., predicted risk of surgical mortality ≥ 8% at 30 days, based on the Society of Thoracic Surgeons (STS) risk score and other clinical co-morbidities unmeasured by the STS risk calculator)..

No survival difference was observed between use of mechanical and bioprosthetic mitral valves in patients aged 50-69 years matched by propensity score (actuarial 15-year survival 57.5% [95% confidence interval (CI) 50.5-64.4%] vs. 59.9% [95% CI 54.8-65.0%], hazard ratio [HR] 0.95 [95% CI 0.79-1.15]), or in a subgroup analysis of age by decade. Among patients matched by propensity score, mechanical versus bioprosthetic mitral valve replacement was associated with higher 15-year incidence of stroke (14.0% [95% CI 9.5-18.6%] vs. 6.8% [95% CI 4.5-8.8%], HR 1.62 [95% CI 1.10-2.39]) and bleeding events (14.9% [95% CI 11.0-18.8%] vs. 9.0% [95% CI 6.4-11.5%], HR 1.50 [95% CI 1.05-2.16]), but a lower incidence of reoperation (5.0% [95% CI 3.1-6.9%] vs. 11.1% [95% CI 7.6-14.6%], HR 0.59 [95% CI 0.37-0.94]).. ...

Subclinical leaflet thrombosis occurred frequently in bioprosthetic aortic valves, more commonly in transcatheter than in surgical valves. Anticoagulation (both NOACs and warfarin), but not dual antiplatelet therapy, was effective in prevention or treatment of subclinical leaflet thrombosis. Subclinical leaflet thrombosis was associated with increased rates of TIAs and strokes or TIAs. Despite excellent outcomes after TAVR with the new-generation valves, prevention and treatment of subclinical leaflet thrombosis might offer a potential opportunity for further improvement in valve haemodynamics and clinical outcomes.. ...

A method is provided for implanting a valve having at least one valve leaflet within the cardiovascular system of a subject. One step of the method includes preparing a substantially dehydrated bioprosthetic valve and then providing an expandable support member having oppositely disposed first and second ends and a main body portion extending between the ends. Next, the substantially dehydrated bioprosthetic valve is attached to the expandable support member so that the substantially dehydrated bioprosthetic valve is operably secured within the main body portion of the expandable support member. The expandable support member is then crimped into a compressed configuration and placed at a desired location within the cardiovascular system of the subject. Either before or after placement at the desired location, fluid or blood re-hydrates the substantially dehydrated bioprosthetic valve.

Prosthetic Cardiac Valve from Pericardium Material and Methods of Making Same - Patent applicationProsthetic Cardiac Valve from Pericardium Material and Methods of Making Same - Patent application
0067] In the embodiments described above relative to FIGS. 7 and 8, the tubular valve segments of stented valves of the invention have a ring of pericardial material that is thicker at one or both of its ends where the material is rolled or folded back on itself. This rolled-back material can overlap or cover the edge of the stent, such as to cover the edge of the stent wires, thereby making the edge or edges of the stented valve smoother. Alternatively, the material may be rolled or folded back in such a way that it does not cover the edge of the stent. For example, a folded portion of material can be positioned so that it is adjacent to an end of a stent and/or the folded portion of material can be positioned to face the interior opening or portion of the stent. In any case, the extra thickness of the material can be beneficial to prevent the stented valve from leaking around its perimeter when implanted in a patient. That is, the rolled or folded areas can help to stabilize the stented valve ...

Implantation of the Sorin Perceval® sutureless aortic valve: a step by step approach - Minerva Cardioangiologica 2017 April;65...
Since the introduction of the sutureless Perceval® (Sorin Group, Saluggia, Italy) in Europe after CE mark in 2012, the sutureless approach is becoming more and more popular. Sutureless implantation in general is easy, fast and safe, but bears several potential pitfalls. This might result in inferior functional results affecting also clinical outcomes. In our center, more than 300 implant procedures have been performed up to date by mainly two senior surgeons. The technique is in the process of spreading to all surgeons performing aortic valve procedures. Proctored activities are completed at our and other institutions, and wetlab activities are conducted in collaboration with the manufacturers research and development laboratory. This article was written to give a step-by-step advice for surgeons who want to start a sutureless program or even have made limited experience with this approach wanting to reconfirm their technique. The focus is kept on surgical aspects regarding indication, ...

Break to Fix? Purposely Fracturing Failed Surgical Valves May Help Transcatheter ViV Delivery | tctmd.comBreak to Fix? Purposely Fracturing Failed Surgical Valves May Help Transcatheter ViV Delivery | tctmd.com
In terms of complications, Chhatriwalla said concerns have been raised about injuring the aorta or rupturing the annulus, though so far these have not been seen. Its also possible that BVF might increase the risk of thromboembolic events, though it might be hard to tease out the mechanism by which they occur, he said.. But there are ways to mitigate risks, Chhatriwalla stressed, such as by timing BVF differently.. Some operators favor doing BVF ahead of TAVR, he said. The thought behind this is that the size of the new TAVR valve is selected with the knowledge of whether or not the bioprosthetic valve can be fractured in the first place. So you fracture the valve first, you have success, and then put in maybe a larger-sized [TAVR] valve as a result, he explained.. But he and others at Saint Lukes prefer doing it after the TAVR device is implanted, Chhatriwalla added. Our mindset [is] were going to put in the valve size thats warranted, and were going to check the hemodynamics. Then if ...

AIM: Postoperative renal dysfunction after aortic valve replacement is a serious complication. To minimize its occurrence, risk factors have to be identified, and if possible eliminated. METHODS: Of 1000 consecutive patients, who underwent AVR, a file study was performed chi(2)nd logistic regression analysis were performed to study the effect of 24 preoperative, 7 peroperative and 7 postoperative factors on the occurrence of 30-day postoperative worsening of renal function. RESULTS: Fifty-three patients had a 30-day postoperative decrease of renal function. Nine of these patients died, which is significantly more than the mortality without this complication ( ...

Fatigue and Biodegradation in Engineered Tissue Devices: At present, about half of all heart valve replacements incorporate tissue-derived components: either transplanted human valves or so-called bioprostheses incorporating chemically-treated porcine or bovine tissues. While tissue valves offer more physiological blood flow and freedom for the patient from significant anti-clotting drugs, these valves typically fail in under 15 years. It has been estimated that more than 90% of all failed tissue valves show tears and perforations in the tissue leaflets; moreover, there is strong pathological evidence that host inflammatory cells are present at the margins of such damage. We are using a unique combination of mechanical fatigue simulation, proteolytic enzymes, and macrophage culture to look at the mechanisms by which engineered tissue valves fail. Weve shown a synergy between fatigue damage to collagen bundles and enzymatic cleavage (that is, the two acting together are more damaging than the ...

Much has changed in the 21 years since Donna Zirkles physician found a lump during her annual breast exam.. The diagnostic mammogram that followed came back negative. Fortunately, Donnas doctor didnt stop there.. Bless my doctor, Donna said. She called me back and said, Donna, I know theres a lump there. Would you please go get an ultrasound? I actually thought about not doing that, but I trusted her. So, I went for the ultrasound, and I saw it on the screen-a little bitty thing.. Donna is one of a small number of patients - fewer than 10% - who receive a false negative from a mammogram. Her family physician sent her to see Cam Gabrielsen, then the breast surgeon at Hancock Health. Even Dr. Gabrielsen had his doubts about whether the 1.3cm tumor was cancerous.. I had a lumpectomy, Donna said. I hadnt signed off for a mastectomy, because they didnt think it was going to be cancer.. It was. And, three weeks later, she ended up having the mastectomy.. It turns out Donnas cancer was ...

  • The lack of evidence on the long-term durability of the bioprostheses used for TAVR remains of particular concern. (regionh.dk)
Calcification2
  • Effect of ethanol and ether in the prevention of calcification of bioprostheses. (structuralheart.abbott)
  • We excluded all described causes related with early bioprosthesis calcification and degeneration. (clinmedjournals.org)
Carpentier-Edwards Perimount1
  • Explanted Carpentier-Edwards Perimount bioprosthesis (view from the left ventricule: A, view from the left atrium: B showing a tear in leaflet 1 (white arrow). (biomedcentral.com)
Pericardial aortic bioprosthesis1
Outcomes2
  • The latest results of the Perigon Study, presented by Prof. Dr. Robert J.M. Klautz during EACTS 2021: Surgical Aortic Valve Replacement with a Stented Pericardial Bioprosthesis: 5-year Outcomes. (medtronic.com)
  • In this retrospective study with matched populations, the RDAVR with the INTUITY valve system provided superior procedural and hemodynamic outcomes than a standard bioprosthesis without compromising safety. (uzh.ch)
Cardiac Bioprostheses2
  • by International Symposium on Cardiac Bioprostheses (3rd: 1985 : London, U.K. (who.int)
  • Types of malfunction Structural valve deterioration The principal complication plaguing cardiac bioprostheses is structural deterioration, often necessitating reoperation and prosthesis replacement. (dermatologyadvisor.com)
Tissue3
  • Current heart valve prostheses may be classified as either mechanical or tissue valves (bioprostheses). (elsevier.com)
  • An aortic homograft was implanted with preserved anterior mitral leafl et which allowed a complete resection of infected tissue and anchoring of mitral bioprosthesis. (muni.cz)
  • However, some primary tissue failures in bioprostheses have been reported. (elsevier.com)
Mortality1
  • Bioprosthesis was independently associated with 1-year mortality (hazard ratio: 1.298). (uab.edu)
Bovine1
  • The mitroflow aortic prosthesis is a bovine pericardial bioprosthesis specially designed to increase the valve area in relation to its size. (rosannemetz.com)
Aortic Position1
  • Hemodynamic evaluation of the Sorin Soprano bioprosthesis in the completely supra-annular aortic position. (tum.de)
Mitroflow1
  • The overall risk for svd is high for the mitroflow bioprosthesis, especially if the prosthesis is small and older than 5 years. (rosannemetz.com)
Mosaic2
  • The valve was resected, and a 27-mm Mosaic mitral bioprosthesis was implanted in its place. (biomedcentral.com)
  • A 64-year-old woman received 29 mm Mosaic mitral bioprosthesis in 2010 after failure of valve repair attempt. (bmj.com)
Endocarditis2
  • Diagnosis of possible infectious endocarditis in the patient was suspected after results of a transesophageal echocardiogram were used as a major criterion (thickened and partial aortic stenosis), and predisposing heart condition (aortic bioprosthesis) were used as a minor criterion ( 3 ) Because blood cultures were negative for the organism, the diagnosis of B . henselae infection was made by using serologic analysis and PCR ( 7 ). (cdc.gov)
  • Lactobacillus gasseri endocarditis on the aortic valve bioprosthesis - a case report. (cfsremission.com)
Clinical3
  • For the first time, the quantitative evaluation of the αGal epitope in heart valve bioprostheses, already in clinical practice for about 40 yrs, was finally determined. (nih.gov)
  • The clinical safety and performance of the Dafodil pericardial bioprosthesis were favourable at 12-month. (biomedcentral.com)
  • We compare clinical and hemodynamic results after AVR with three bioprostheses with different design and characteristics. (unicatt.it)
Rheumatic1
  • He had had an aortic valve replacement and a bioprosthesis was inserted in 2005 for rheumatic disease. (cdc.gov)
Thrombosis1
  • BPVT is, simply put, thrombosis forming over a bioprosthesis. (medscape.com)
Echocardiography1
  • The application of advanced echocardiography on an animal model was feasible and helpful in guiding the continuous refinements needed to enhance the development of this new concept of bioprosthesis. (unipd.it)
Vascular1
  • LeMaitre Vascular has acquired the ProCol vascular bioprosthesis product line from Hancock Jaffe Laboratories for US$665,000 plus a three-year royalty. (vascularnews.com)
Procedure1
  • However, cases involving a Ross procedure, in which the aortic valve is replaced with the patient's own pulmonic valve and the pulmonic valve is then replaced with a bioprosthesis is not considered a "multiple valve" procedure and may be evaluated for a special issuance medical certification by the FAA staff physicians. (aopa.org)
Treatment2
  • Bioprosthesis has been increasingly implanted for the treatment of transvalvular disease across the world. (biomedcentral.com)
  • Advances in Anticalcific and Antidegenerative Treatment of Heart Valve Bioprostheses. (structuralheart.abbott)
