The algorhythm of choosing the optimal access for mitral valve replacement in patients with high surgical risk

Aims: to compare the efficacy and safety of mitral valve (MV) prosthesis using different surgical accesses (median sternotomy and lateral thoracotomy) in overweight patients; to evaluate the influence of the choice of access on complications, quality of life, survival and cardiac function, as well as to determine the risk factors for complications in combined surgical treatment of coronary heart disease and MV prosthesis.
