Outcomes of complex mitral valve repair through right mini-thoracotomy using artificial chordae

Mitral regurgitation (MR) affects 2%–3% of the global population. The rising incidence of degenerative causes in developing countries leads to an increase in the number of surgeries for degenerative MR. In this study, we aimed to evaluate the safety, feasibility, and effectiveness of minimally invasive mitral repair (MIMR) using artificial chordae in complex cases of mitral valve regurgitation.
