Evaluation study of the size and function of mechanical heart valve replacement operations in Al Nasiriyah Heart Center

The size and function of mechanical heart valves were evaluated in this article. pathological cases that produce valve damage lead to the most well-known rheumatic illnesses have been investigated. They induce stenosis regurgitation valve, whether aortic or mitral, other diseases, such as degenerative, congenital, calcific valves. These occurred between 2015 2020, following are relevant characteristics include; patient's age, height, weight, kind operation, cause, size, before complications after procedure, cross-clamp time, Ejection Fraction (EF), New York Heart Association (NYHA) operation. All collected from database. Because is directly mainly connected surface area, height weight used extract area correlate it size. It was also noticed mitral more significant than because profound aorta. often replaced (51%), followed by (31%) double (18 %). number patients who a replacement procedure fluctuates yearly, depending on severity damaged valve. In some instances, might be fixed without needing replacement. Despite difficulties there relatively few deaths, data show only two deaths five years due failure during operation cerebrovascular accidents.
