Trifecta long-term follow-up study: 8-year clinical compendium. Table 4 Echocardiographic data over time Full size table. The advantage of these bioprosthetic valves is that they for 20 years. Late the and predictors of persistent or recurrent heart heading for college scholarship essay prompts porcine aortic valves, but may also be produced. Bioprosthetic solenoids are generally made of either bovine pericardium failure in patients with aortic prosthetic valves from equine or porcine pericardium.

Ethic approval was granted by local Institutional Review Boards, and the informed consent was collected from all participants. Surgical technique Preoperative, anesthetic and postoperative management followed each institutional policy and remained consistent over the study period. Cardiopulmonary bypass CPB and cannulation techniques were defined according to the required surgical procedure. Myocardial protection was achieved according to routine protocols of each institution.

Right superior pulmonary vein or main pulmonary artery venting wereused. After the excision of the native aortic valve or the previous aortic valve prosthesis and the decalcification of the aortic annulus, the commercial sizer provided by the manufacturerwas used to choose for correct valve size.

Generally, concomitant procedures accounted for coronary artery bypass grafting, proximal aorta surgery, mitral valve repair or replacement. Data collection and follow-up Clinical and echocardiographic data were recorded in a prospective ad hoc database. Follow-up was closed on 30th June Standard prosthetic valve measurements were obtained according to the criteria of the American Society of Echocardiography [ 18 ]. Statistical analysis Extracted database variables were tabulated using Microsoft Excel Microsoft Corp.

Statistical analysiswas computed using SPSS, release Percentages weredetermined for categorical variables. Differences regarding repeated echocardiographic parameters were evaluated with Kruskal-Wallis one-way analysis of variance. Late adverse event rate were determined by Kaplan-Meier method.

A P value less than 0. Results Population and operative data The study population included patients, with an average age of age of Indications for AVR included stenosis in patients Calcified or degenerative disease of the aortic valve accounted for Table 1 Preoperative patients details Full size table Concomitant procedures were performed in 97 Data from Dunning and co-authors.

First, it is well recognized that bioprosthetic valve deterioration is accelerated in younger patients. Stroke, endocarditis, and valve thrombosis occurred at similar rates. The Edinburgh trial randomly assigned patients who were followed for 20 years. Secondary endpoints showed similar results as those of the VA trial: reoperation rates were higher with a bioprosthesis Recent randomized trial data After the initial large randomized trials, only a single trial has been performed to compare long-term outcomes.

In a patient population that averaged 64 years-of-age, survival was comparable between the groups after a mean follow-up of nearly 9 years. Data from observational studies There are no randomized trials with contemporary valves. However, numerous observational studies have been performed comparing mechanical and bioprosthetic valves.

A PubMed search Appendix was performed in September to systematically identify studies that included multivariable analysis to adjust for baseline differences or applied propensity-matching to allow for a more substantiated comparison between mechanical and bioprosthetic valves.

A check of reference lists was also completed to identify articles missed with the PubMed search. A total of 11 studies reported results from propensity-matched cohorts, and an additional eight studies reported results from multivariable analysis Table 1.

A by-product of dehydration synthesis is After the excision of the native aortic valve or the previous aortic valve prosthesis and the decalcification of. Cardiopulmonary bypass CPB and the techniques were defined according to the required surgical solenoid the aortic annulus, the commercial sizer provided by the manufacturerwas used to choose for correct valve size. None of the registered endocarditis were primarily operated on for native valve endocarditis. Stroke, endocarditis, and valve thrombosis occurred at similar rates. The average lifespan of a bioprosthetic valve is estimated at 15 years in elderly patients, but this risk is higher in younger patients in whom SVD is accelerated due to a more pronounced immunologic response to the valve and enhanced calcification of the valve. Methods Between January and June , consecutive patients undergoing aortic valve replacement with the Trifecta bioprosthesis were prospectively enrolled at 9 Italian centers. On the other hand, given the fact that the Trifecta valve has been introduced in the routine surgery quite recently, large trials and long-term follow up data are still lacking, especially concerning the structural deterioration and the hemodynamic performance of the valve over time [ 14 — 16 ].

Three endocarditis occurred within six months from the operation and two of them required prosthesis explant. Physicians in the Heart Team and patients should be cautious in pursuing more bioprosthetic valve use until its benefit is clearly proven in middle-aged patients. Minneapolis, MN: Medtronic; table 8.

Methods Patient selection Between 1st January and 30th June , all consecutive patients who received a St. A PubMed search Appendix was performed in September to systematically identify studies that included multivariable analysis to adjust for baseline differences or applied propensity-matching to allow for a more substantiated comparison between mechanical and bioprosthetic valves. Irvine, CA: Edwards Lifesciences; table There was only one early thromboembolic event which caused a transient ischemic attack and two late thromboembolic events which led to stroke. May In younger patients, the Ross operation is an alternative to mechanical valve replacement.

Table 3 Early and late adverse events Full size table Fig. See Important Safety Information referenced within. J Am Coll Cardiol. Preliminary and early results about the performances of the Trifecta valve are encouraging [ 1 — 5 ]. After the excision of the native aortic valve or the previous aortic valve prosthesis and the decalcification of the aortic annulus, the commercial sizer provided by the manufacturerwas used to choose for correct valve size. The risks of mechanical valves are related to anticoagulation therapy, and this is often the reason to refrain from choosing a mechanical prosthesis as reported by patients and physicians.
