Conclusion
Our data illustrates that the use of PAR, such as the Freestyle, can be
used to replace the diseased aortic root at the time of repair of TAAD
with acceptable intra- and post-operative mortality & morbidity.
Mid-term survival are satisfactory echocardiographic outcomes are more
favourable than CVG in the early phase. Especially in the elderly
population, PAR can be considered as a first line option when indicated.
More studies are required to confirm the durability, freedom from
structural valve degeneration, and long-term clinical outcomes of this
group of patients.
