The present study highlighted the technical feasibility to produce polymeric bioresorbable functional heart valves by means of electrospinning.[ncbi.nlm.nih.gov]
Further study in this area should concentrate on the impact of valve type on left ventricular recovery post-implantation to provide additional information to the surgeon when selecting a valve from the plethora of choices available.[ncbi.nlm.nih.gov]
Morbidity occurred in 10 patients (20.8%), including reexploration for bleeding in two (4.2%), wound infection in two (4.2%) and pneumonia in two (4.2%), endocarditis in one (2.1%), renal failure in one (2.1%), hepatic failure in one (2.1%) and refractory hiccup[jtd.amegroups.com]
BACKGROUND: In this study, we present a single center experience with Bicarbon bileaflet valve in 307 patients with rheumatic heartdisease.[ncbi.nlm.nih.gov]
Stenosis - when the valve doesn't open enough and blocks blood flow Valve problems can be present at birth or caused by infections, heart attacks, or heartdisease or damage.[icdlist.com]

The main sign of heart valve disease is an unusual heartbeat sound called a heartmurmur. Your doctor can hear a heartmurmur with a stethoscope. But many people have heartmurmurs without having a problem.[icdlist.com]
Symptoms The main symptom of heart valve disease is a heartmurmur. Yet some people may have heartmurmurs without having heart valve disease.[verywell.com]
On auscultation, valve clicks may be diminished or absent with additional systolic or diastolicmurmurs. Detection of the “double click” may be useful for early diagnosis of dysfunction of bileaflet prostheses.[jtd.amegroups.com]
The frequency analysis to identify different valves was unsatisfactory, but louder frequencies did correspond with hearing-impaired patients' audiograms.[ncbi.nlm.nih.gov]
A patient with a mechanical valve prosthesis, in the first trimester of pregnancy, stopped taking her warfarin because of personal fears about teratogenicity. Prosthetic valve thrombosis developed, and she required redo mitral valve replacement.[ncbi.nlm.nih.gov]
Six women with mechanical heart valve prosthesis, who were admitted with persistent severe vaginalbleeding between 2003 and 2010, were evaluated.[ncbi.nlm.nih.gov]
CONCLUSIONS: Our results emphasize the need for valve design changes, preoperative education about the sound, and inclusion of routine hearing tests into the preoperative workup.[ncbi.nlm.nih.gov]
[…] implantation (TAVI)/transcatheter aortic valve replacement (TAVR), except those in whom CT is contraindicated, [3, 4] and that the CT images should be interpreted with a member of the TAVI/TAVR team or reviewed with the operator before the procedure See Workup[emedicine.medscape.com]
Because of the twin problem of heart disease and anticoagulant therapy, treatment of abnormal vaginal bleeding in these women is extremely challenging.[ncbi.nlm.nih.gov]
Outlook (Prognosis) The success rate of heart valve surgery is high. The operation can relieve your symptoms and prolong your life. Mechanical heart valves do not often fail. However, blood clots can develop on these valves.[leehealth.org]
Long-term prognosis is generally benign in patients with mild paravalvular regurgitation identified by perioperative echocardiography, with progression of regurgitation requiring reoperation in 1 to 2 years. 78 Hence, closer follow-up appears justified[circ.ahajournals.org]
The mortality rate with a fungal etiology is 93%. The mortality rate for staphylococcal infections is 86%. PVE due to Staphylococcus has a mortality rate of 25-40%. [13, 14] Fatal anticoagulant-induced hemorrhage occurs in 0.5% of patients per year.[emedicine.medscape.com]

Epidemiology Frequency United States Prosthetic valve thrombosis is more common in mechanical valves. With proper anticoagulation, the rate of thrombosis in all valves is within the range of 0.1-5.7% per patient-year.[emedicine.medscape.com]
No significant differences were seen in major embolism or endocarditis. [11] Pathophysiology Valve failure Primary valve failure may occur abruptly from the tearing or breakage of components or from a thrombus suddenly impinging on leaflet mobility.[emedicine.medscape.com]
Abstract This study evaluated the advantage of an anticoagulation clinic in terms of the improvement of the clinical quality of oral anticoagulation (i.e. prevention of thromboembolism and low rate of hemorrhagic complications).[ncbi.nlm.nih.gov]
