Older patients generally receive bioprosthetic valves because these valves are less prone to clotting and bleeding complications. (jwatch.org)
For bioprosthetic valves, the risk of repeat surgery was greater but the incidence of major bleeding was lower. (medscape.com)
In propensity-matched comparisons, actuarial 15-year mortality rates were 60.6% with the bioprosthetic aortic valve and 62.1% with the mechanical valve. (medscape.com)

Pre-operative echocardiographic measurements of the annulus and computed tomography measurements of valve calcium were made. (duke.edu)

For these peculiarities and the higher rates of paravalvular leak (PVL), new permanent pacemaker (PPM), need for a second transcatheter heart valve (THV), risk of annulus rupture or aortic dissection, and brain injury ( 13 - 15 ) BAV patients have been initially excluded from the randomized trials. (frontiersin.org)
CONCLUSIONS: These data suggest that measuring AIBP during balloon aortic valvuloplasty in tricuspid valves is an important adjunctive measurement of the aortic annulus and may help in determining the appropriate THV size. (duke.edu)
They relate to size of aortic annulus and blood flow through the heart. (diagnosticdetectives.com)
What remains uncertain is if the commissural fusion would be "split", as with mitral valvuloplasty, or if the annulus would merely be stretched to accommodate the new valve. (heartvascularcentre.com)

Signs and symptoms of prosthetic heart valve malfunction depend on the type of valve, its location, and the nature of the complication. (medscape.com)
In patients receiving first‐generation valves, ≈12% of patients experienced a major vascular complication and 16% a life‐threatening bleed, as defined by the Valve Academic Research Consortium criteria. (ahajournals.org)

Both patients were in New York Heart Association functional class IV heart failure with depressed left ventricular ejection fraction and additional comorbidities. (researcher-app.com)
Acutely, post-procedural echocardiograms demonstrated excellent prosthetic valve function with a low transvalvular gradient and no paravalvular leak and left ventricular outflow tract obstruction. (researcher-app.com)

More information on the American Heart Association's Target: Aortic Stenosis program can be found at www.heart.org/TargetAS . (beckershospitalreview.com)
When there is stenosis or tightening of the aortic valve and the flow of blood is hindered, this causes symptoms of fatigue, chest pain, shortness of breath on minimal exertion or even fainting. (portugalresident.com)
A patient presenting with uncontrolled heart failure should be treated supportively with oxygen, cardiac and oximetry monitoring, intravenous access, loop diuretics, nitrates (remembering the potential nitrate sensitivity of patients with aortic stenosis), morphine (as needed and tolerated), and noninvasive or invasive ventilatory support (as indicated). (medscape.com)
Patients with severe heart failure due to aortic stenosis that is resistant to medical management should be considered for urgent surgery. (medscape.com)

Unlike valves with a conventional cavity pivot hinge design, Medtronic Open Pivot valves have no recesses or cavities where potential thrombogenesis can occur. (medtronic.com)

AOA treatment is Medtronic's biochemical approach to mitigating calcification in the wall and leaflets of tissue valves. (medtronic.com)
Balloon-expandable valves have been considered not suitable for native aortic regurgitation because of the lack of calcification to anchor the prosthesis," the researchers noted, but they concluded that their preliminary evidence suggests it might be safe for selected patients. (medpagetoday.com)
Multi-detector computed tomography (MDCT) plays a central role in procedure planning by providing high spatial resolution of the valve morphology, dimensions, and pathological characteristics such as calcification, deployment angle, and anatomy of the peripheral arteries [ 3 ]. (springeropen.com)
