Why the study?
The combination of aortic regurgitation, rheumatoid aortitis, and subaortic stenosis is rare in rheumatoid arthritis, and surgical treatment can be challenging with non-adequate results.
Aortic valve reconstruction using bovine pericardium (Ozaki technique) can be a viable salvage surgical option for acute prosthetic failure in patients with severe rheumatoid aortitis and an inaccessible aortic root.
