INTRODUCTION
Valvular heart diseases are quite common in developed countries and have
a high incidence rate. Among the heart surgeries performed in these
countries, heart valve surgeries rank second in number. [1]. In
recent years, the number of patients with advanced age and serious risk
profile undergoing cardiac surgery has been increasing. Despite this
negativity, surgery is a safe treatment method with low morbidity and
mortality for almost all patients, thanks to the progress in cardiac
anesthesia and surgical techniques [2]. In previous studies, the
mortality rate following heart valve replacement has been reported to be
between 4.3% and 14% [3].
The most important purpose in mitral valve surgery; It is the
preservation of left ventricular function by preventing left ventricular
dilatation before an irreversible damage occurs in the myocardium, and
if it is not possible, it is the replacement of the valve that has lost
its function before serious symptoms appear [4]. In the treatment of
valve diseases, the surgical treatment that will contribute the most to
the dimensions and functions of the left ventricle is the repair of the
valve without damaging the anatomical structure of the valve and using a
prosthetic valve. Prosthetic valve replacement is applied for valves
that are severely degenerated and not suitable for repair. Preservation
of the subvalvular structure consisting of the chordae and papillary
muscles, which are the elements of the functional apparatus of the
mitral valve, provides a positive effect on left ventricular function
and helps prevent left ventricular dilatation and left ventricular
segmental wall motion disorder [4,5]. However, the lack of
randomized studies comparing long-term results is evident. It is known
that heart surgeries performed with minimally invasive methods and
robotic surgery generally decrease the morbidity associated with surgery
and have good early results.
However, they must prove themselves within the framework of this
equation by showing that the long-term results of this technique are
also good. In this study we have done, we aimed to compare the results
of conventional mitral valve surgery performed with sternotomy for many
years and robotic mitral valve surgery, which continues to develop.
