The initial experience with the ATS Medical mechanical cardiac valve prosthesis. Objectives We describe our experience with a new mechanical valved conduit, the Carbomedics Sinus of Valsalva composite graft. Early clinical experience with the On-X prosthetic heart valve. The number is useful to epidemiologists because it is a measure of the risk of disease.It is called "Carbon-12," which is abbreviated "C." The fact that the atom has six protons is what makes it carbon.Most nitrogen atoms have seven protons and seven neutrons, so their atomic mass is 7 7 = 14.Your continued use of our website constitutes understanding and acceptance of these changes. Clinical experience and Doppler echocardiographic assessment of the first one hundred ATS AP (advanced performance) prosthetic valve in the aortic position. The current Food and Drug Administration (FDA) heart valve guidance document uses an objective performance criteria (OPC) methodology to evaluate the clinical performance of prosthetic heart valves. J Cardiovasc Surg.1999;7-81 Butterfield M, Fisher J, Davies GA et al. Four-year experience with the Carbo Medics valve: the North American experience.The results demonstrate that after a minimum of 10 years, Carbomedics valves show outstanding quality values. Fifteen years of clinical and echocardiographic follow up with the Carbomedics heart valve. Study M Emery RW, Van Nooten GJ, Tesar PJ; Investigators for the ATS Clinical Open Pivot Heart Valve Food and Drug Administration Study. The OPC are derived from the average complication rates of all approved heart valves. Comparative study of the hydrodynamic function of the Carbo Medics valve. North American team of clinical investigators for the Carbo Medics prosthetic heart valve.
Transesophageal echocardiography has emerged as the imaging study of choice in patients with a suspected prosthetic valve complication.
INR 2-3 for 3 months following implantation; anticoagulation may then be discontinued unless the patient has another indication, such as atrial fibrillation or development of prosthetic valve thrombosis.
An overpenetrated anteroposterior chest radiograph helps to delineate the valvular morphology and whether or not the valve and occluder are intact.
Conclusions Despite the degree of complexity of operations in this study, this valved conduit is a very acceptable prosthesis for a modified Bentall procedure.
It can be used for a variety of aortic pathology, both electively and in emergent settings.
