Avatar n tn Abstract Although most of the available prosthetic heart valves function remarkably well, the variety of available choices attests to the inability of any single one to fulfill the requirements of the ideal valve substitute. The mechanical prostheses include the caged-ball, tilting-disc, and bileaflet valves. Tissue valves available in the United States are the Carpentier-Edwards and Hancock porcine heterograft valves and the Carpentier-Edwards pericardial valve.

Avatar n tn The use of a metallic valve requires the long-term use of anticoagulation without ever stopping. Those valves tend to last longer. Tissue valves do not require long-term anticoagulation but have a limited lifespan (typically 10-15 years). Most of the patient's I see end up getting a tissue valve because of the anticoagulation issue. Also, if a new valve is required in the future, percutanous options will likely be available while that will not be an option with a mechanical valve.
Avatar n tn Certain heart valves require anticoagulation(blood thinning) with coumadin to lessen an increased risk of blood clot formation. These are usually the mechanical, or metal, valves. Now, if your father received a bioprosthetic valve which is made from animal tissue, you are correct in your understanding that coumadin would not typically be required. However, it is possible that he suffers from another condition that would necessitate anticoagulation.
Avatar n tn If you would like to make an appointment at the Cleveland Clinic Heart Center, please call 1-800-CCF-CARE or inquire online by using the Heart Center website at www.ccf.org/heartcenter. The Heart Center website contains a directory of the cardiology staff that can be used to select the physician best suited to address your cardiac problem.
Avatar n tn What is the expected longevity of the different types of prosthetic heart valves? What are the factors to be considered when choosing a valve? How much patient input is appropriate in making the determination as to which valve to use?
Avatar n tn 21 Dear Todd, thank you for your input to the heart forum. Aortic valves that are stretched and leaking due to aortic aneurysms can sometimes be repaired, but stenotic aortic valves cannot be repaired and must be replaced. I agree with your thoughts on an aortic homograft, as my response indicates.
Avatar n tn I am wondering how long the St Judes Valves are lasting in general. I have the mitral and the aortic valves. What are the main factors in general health contributes to re-replacement. Thank you Kathy Dear Kathy, thank you for your question. St. Jude's valves are known to be very durable and can last for 20 - 30 years.
Avatar n tn ) Is there a website or other forum you are familiar with where I can find more information about Coumadin, and also talk with young people who have mechanical heart valves so I can get a better understanding of the impact on my lifestyle this surgery will have? 4.) Could you recommend books that will help in determining the amount of vitamin K are in certain foods? 5.
Avatar n tn You are correct in stating that porcine valves are not as durable as mechanical valves but do not require anticoagulation other than aspirin. The typical duration of a porcine valve is 10-15 years, but is less in someone with renal failure that is not relieved with transplantation.
Avatar n tn Aortic homografts are from cadavers and also do not require anticoagulation and may last longer than other types of tissue valves. No one really knows how long but it is probably more than 10 years. The chief disadvantage of the homograft is availability. I hope you find this information useful. Information provided in the heart forum is for general purposes only. Only your physician can provide specific diagnoses and therapies. Please feel free to write back with additional questions.
Avatar n tn t repairable, I had chosen the homograft for replacement - the risks of reoperation were better than the risks of anticoagulation. Although many people have no problem with anticoagulation, there are risks and quality of life issues that you need to inform yourself about. Good Luck.
Avatar f tn Should i go with a mechaical valve or a tissue valve? I am 38 yrs old. I had open heart Dec. 2008, and now one yr later I must go in again. I have a tissue valve now.
Avatar n tn Putting in a tissue valve sounds good, but these do not grow with the child and are often damaged by the immune system. Mechanical valves don’t grow, either, and require lifelong anticoagulation to prevent clots from forming on the valve. A Ross procedure, in which his pulmonary valve is used as the replacement aortic valve, and then a pulmonary homograft (a cadaveric pulmonary valve and artery) replace the native pulmonary valve, is not a great option, either.
Avatar n tn m 33 and had an aneurysm and aortic valve repair in September 98. There is good information on tissue valves (both porcine and homograft) availble at http://hsf.cjp.com/, then select Links, then select On-line Journals, then select Annals of Thoracic Surgery. The December Supplement is devoted to tissue valves - the very latest information.
Avatar f tn Coumadin pre-operatively, as you state one considers the risks of hemorrhage or thromboembolism versus the benefit from the operation. When considering noncardiac surgery, these factors and the need to weigh the risk of hemorrhage against that of thromboembolism must analyzed on an individual patient basis. Certain procedures such as a bunion that are not procedure that threatens limb or life are easy analysis.
