Minimally invasive mitral valve surgery.
Minimally invasive mitral valve surgery (MIC-MVS) was introduced into clinical practice in the mid 1990s. Since then it has evolved as the standard technique at some specialized centers. The routine technique includes femoral access for extracorporeal circulation, a right lateral minithoracotomy and direct aortic clamping using special instruments. Different techniques leading to some variations have been described. There is no prospectively randomized trial comparing minimally invasive with conventional mitral valve surgery. However, several series including large patient numbers and up to 8 years of follow-up have been published. Literature results as well as different aspects of minimally invasive MVS are discussed in this review, including the development, the current technique and future perspectives. Regarding MIC-MVS the word is that it is a safe and effective operation. Lateral minithoracotomy access offers excellent exposure, visualization can be further enhanced when using endoscopic cameras. All different mitral valve repair procedures can be performed even in the presence of complex pathologies. The repair rate is excellent and reaches 75%. Patient recovery is fast leading to a significant improvement in individual quality of life. MIC-MVS can now be considered the standard approach and will reach more widespread clinical application.
