Prosthetic heart valve.
A 55-year-old invasive/clinical cardiologist worked full time, exercised regularly, and was asymptomatic. Two weeks previously, he had new onset of angina on exertion. Echocardiography/Doppler and cardiac catheterization confirmed the clinical assessment of severe aortic stenosis with a valve area of 0.5 cm/m. The aortic valve was tricuspid; left ventricular ejection fraction was 0.60. Coronary...
متن کاملSound spectroanalytic diagnosis of malfunctioning prosthetic heart valve.
Sound spectroanalysis was carried out for diagnosis of malfunctioning prosthetic heart valves in 50 cases, which consisted of 31 mitral, 14 aortic, 4 mitral+aortic and 1 tricuspid valve replacements with the age ranging from 17 to 57 years. Types of prosthetic valves used in this series were Starr-Edwards silicon ball valves, metal ball valves, disc valves, Kay-Shiley valves, Smeloff-Cutter val...
متن کاملFabrication and characterization of nanofibrous tricuspid valve scaffold based on polyurethane for heart valve tissue engineering
Objective(s): Tissue engineering represents a new approach to solve the current complications of the heart valve replacements by offering viable valve prosthesis with growth and remodeling capability. In this project, electrospinning and dip coating techniques were used to fabricate heart valve constructs from medical grade polyurethane (PU). Methods: Fir...
متن کاملTreatment of obstructive thrombosed prosthetic heart valve.
Obstructive thrombosed prosthetic heart valve (OTPHV) is a serious complication of heart valve replacement. There are no generally accepted criteria for management of these patients. Therefore, in September 2012, a literature survey of studies published after 1995 was performed to analyze the data regarding clinical outcomes of patients with OTPHV treated with thrombolytic agents and with surge...
متن کاملProsthetic valve endocarditis: state of the heart
Prosthetic valve endocarditis (PVE) is a rare but serious complication of cardiac valve replacement surgery and is associated with high rates of morbidity and mortality. Despite significant advances in our understanding of the pathogenesis and management of this disease process, the rates of undesirable outcomes, including mortality directly attributable to infection, remain unacceptably high. ...
