Minimally invasive surgery for valve disease

Abstract

Heart valve surgery evolved since the early 1960s toward routine clinical application with good patient outcome. Different surgical techniques and valve prostheses have been developed. Thus standard procedures were continuously established. The different surgical procedures have now gained widespread clinical acceptance with good patient outcomes. Aortic valve stenosis and mitral valve incompetence are the most frequently acquired heart valve lesions in the western communities. Usually such lesions reach clinical significance in patients during their fifth to eighth decade of life. Standard surgical techniques of aortic valve repair and mitral valve replacement or repair result in persistent cure of the disease. Surgical access was gained using conventional lateral thoracotomies in the early days and later on using median sternotomy. Minimally invasive techniques, mostly by a partial sternotomy for the aortic and a lateral minithoracotomy for the mitral position, have been increasingly applied to improve patient outcome since the mid 1990s. At specialized centers these techniques have evolved as clinical standard allowing all different valve procedures to be safely performed. Patient recovery is fast leading to a significant improvement in the individual's quality of life. Minimally invasive valve surgery can be considered the standard approach and will reach more widespread clinical application.
