Introduction Mitral valve diseases affect 18.1 million people every
year, and the increased life expectancy has led to increased
disability-adjusted life-years. Depending on the type of valve that is
used to replace mitral valves, the type of complications differs. While
a bioprosthetic valve has a lower bleeding risk than a mechanical valve,
the overall durability is generally lower. However, the novel
generations of valves are suggested to have better durability. This
study was conducted to assess the durability and complications of either
type of valve. Materials and methods This study is a retrospective
cohort study that assesses the risk factors, complications, performance
and durability of valves in short and long follow up. The cases of this
study included all patients who had undergone valvuloplasty from 2004 to
2014. Results The results show that the mortality rate and admission
duration is not significantly different between the two types of valves.
However, reoperation rates are higher among bioprosthetic valves by
three times. Cardiac tamponade, pleural effusion, and valvular
thrombosis rates are higher among mechanical valves in the short term,
while GI bleeding, valvular thrombosis, valvular thrombectomy rates are
more prevalent with mechanical valves in the long term. Conclusion While
bioprosthetic valves inflict more minor complications their overall
durability is less than mechanical valves.
