Minimum incision techniques in cardiac surgery have been on the rise after their inclusion in videothoracoscopy. Video-assisted minimally invasive cardiac surgery is considered by many centers in the world to be the approach of choice for treatment of mitral and aortic valve diseases. The aim of this is study is to report a case of valve repair in a patient with mitral restenosis after surgical repair 12 years before. Through a minimally invasive and totally endoscopic procedure, it was possible to successfully perform a mitral commissurotomy with only videoscopic support, and without any incisions larger than those needed to introduce the trocars for instrumentation.
