Presentation
The present study highlighted the technical feasibility to produce polymeric bioresorbable functional heart valves by means of electrospinning. [ncbi.nlm.nih.gov]

- Collapse
It is believed that they were the result of the collapse of cavitation bubbles. The strong HPO did not appear in the flexible mounting signals. [ncbi.nlm.nih.gov]

It has shown excellent results in terms of durability. 37,22 Collapsing, Not Crimping Examination of the results after collapsing and deployment revealed optimal cusp cooptation and absence of tears, perforation or folding. 32 Reduced Physiologic Impact [livanova.sorin.com]
- Congestive Heart Failure
When one of these valves malfunction, it can cause the heart to enlarge and lead to other complications, including congestive heart failure and death. [heart-valve-surgery.com]
These events result in the slowly progressive failure of the valve. The presentation is usually that of gradually worsening congestive heart failure, with increasing dyspnea. [emedicine.medscape.com]
Mitral PPM is independently associated with persisting pulmonary hypertension, increased incidence of congestive heart failure, and reduced survival after MVR. 28,29 Prevention of PPM In light of data published in the literature, the surgeon should attempt [circ.ahajournals.org]
- Falling
Medical News Today recently reported that cardiovascular risk falls in patients with rheumatoid arthritis. [medicalnewstoday.com]
The main reason for applying restraints, usually sheets or body binders, was to prevent the patient from falling out of, or slipping from chairs, rather than to stop them from rising out of them. [ima.org.il]

Respiratoric
- Dyspnea
In patients with dyspnea, the New York Heart Association functional classification was 2.7 +/- 0.8 preoperatively versus 1.3 +/- 0.6 postoperatively. In patients with angina, it was 2.6 +/- 0.6 preoperatively versus 1.03 +/- 0.2 postoperatively. [ncbi.nlm.nih.gov]
In one patient who had an aortic valve replacement 10 years ago and suffered from dyspnea for 2 months, one leaflet of the previously implanted bileaflet prosthesis was found to be missing during reoperation. [jtd.amegroups.com]
Presentations may include the following: Acute prosthetic valve failure: Sudden onset of dyspnea, syncope, or precordial pain Acute aortic valve failure: Sudden death; survivors have acute severe dyspnea, sometimes accompanied by precordial pain, or syncope [emedicine.medscape.com]
Patients were referred to AVR, if they suffered from isolated severe AS (peak velocity ≥4 m/s and mean pressure gradient ≥40 mmHg in the presence of normal left ventricular function, calculated valve area 2 ) and presented with symptoms (exertional dyspnea [journals.plos.org]
Diagnosis Valve thrombosis should be suspected in any patient with any type of prosthetic valve who presents with a recent increase in dyspnea or fatigue because valve thrombosis can develop gradually and insidiously over several days or weeks. 9 Suspicion [circ.ahajournals.org]
Cardiovascular
- Heart Disease
BACKGROUND: In this study, we present a single center experience with Bicarbon bileaflet valve in 307 patients with rheumatic heart disease. [ncbi.nlm.nih.gov]
Heart Valve Diseases Also called: Valvular heart disease Your heart has four valves. Normally, these valves open to let blood flow through or out of your heart, and then shut to keep it from flowing backward. But sometimes they don't work properly. [icdlist.com]
Valve replacement; Valve repair; Heart valve prosthesis; Mechanical valves; Prosthetic valves Heart valve surgery is used to repair or replace diseased heart valves. [stlukes-stl.com]
- Heart Murmur
The main sign of heart valve disease is an unusual heartbeat sound called a heart murmur. Your doctor can hear a heart murmur with a stethoscope. But many people have heart murmurs without having a problem. [icdlist.com]
Yet some people may have heart murmurs without having heart valve disease. [verywell.com]
- Diastolic Murmur
[…] prosthetic valves: Low-grade systolic murmur (caged ball valves); short diastolic murmur (bioprostheses and, occasionally, St. [emedicine.medscape.com]
On auscultation, valve clicks may be diminished or absent with additional systolic or diastolic murmurs. Detection of the “double click” may be useful for early diagnosis of dysfunction of bileaflet prostheses. [jtd.amegroups.com]
- Systolic Murmur
[…] prosthetic valves: Low-grade systolic murmur (caged ball valves); short diastolic murmur (bioprostheses and, occasionally, St. [emedicine.medscape.com]
Psychiatrical
- Fear
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]
Neurologic
- Headache
100°F(38.4°C) Sweats or chills, particularly night sweats Skin rash Pain, tenderness, redness or swelling Wound or cut that won't heal Red, warm or draining sore Sore throat, scratchy throat or pain when swallowing Sinus drainage, nasal congestion, headaches [my.clevelandclinic.org]
Workup
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]

Treatment
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]

Prognosis
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. [stlukes-stl.com]
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]
Etiology
Mechanical valve dysfunction can be classified as endogenous and exogenous according to the etiology. [jtd.amegroups.com]
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
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]
Pathophysiology
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]
Prevention
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]
