Abstract
As an alternative to stented valves, the Freestyle aortic valve—a bioprosthetic valve produced from pig tissue with limited polyester fabric coverings—is utilised to replace the aortic valve. They may be implanted using one of three methods: 1.) sub coronary, 2.) modified sub coronary, or 3.) transluminal Embedding the roots or completely changing them out are options number 2 and 3, respectively. All three leaflets are ready for use after undergoing a low-pressure glutaraldehyde fixation procedure (less than 2 mm Hg).
Without regard to age restrictions, it is utilised to replace a natural aortic valve that has become sick or a prosthetic valve that has developed a serious infection.
Echocardiography and CT scanning are two of the approaches that might be used to evaluate the valve’s anatomy and function. There are benefits to using any of them.
Because it is bioprosthetic, the patient does not need to take an oral anti-coagulant for the rest of his or her life, as would be the case with a metallic valve.
Our research seeks to determine how common subclinical leaflet thrombosis is and to what extent it represents a genuine problem in such valves.
To complement echocardiography’s other benefits, such as its capacity to evaluate functioning valves and estimate the effective orifice area, we employed MDCT in our research due to its excellent spatial resolution.
Results
We included 83 patients who’d had aortic valve replacement with the Glide bio prosthetic valve that had MDCT scans at the Aswan Heart Centre to look at the valves, measure thrombus development, function, aortic valve area, and coronary artery health.
A total of 30 individuals were found to have acquired subclinical thrombus. In addition, calcification of the annulus, a marker of valve degradation, increased during the course of the follow-up period. There were only four confirmed cases of LVOT aneurysm, and neither a reduction nor an increase in the orifice’s effective size had any appreciable influence on the disease’s prevalence.
Recommendations
Finally, subclinical leaflet thromboembolism is a typical consequence of the Freestyle bioprosthetic valve. A typical secondary consequence is degenerative calcification.
