From minimally invasive to percutaneous aortic valve replacement
The incidence of valvular heart disease (VHD) has steadily increased over the past few decades in western communities and is expected to continuously do so in the face of an aging population. The majority of valvular lesions in Europe and North America are of an acquired origin and occur in the fifth to eighth decade of life. Calcified aortic valve stenosis (AS) and degenerative mitral valve regurgitation (MR) are the two most frequent forms of acquired VHD and account for over 70% of cases in Europe . In Germany, about 98 000 cardiac surgical procedures are performed annually. In 2008, 33 400 cases included valve procedures with 12 300 patients receiving isolated aortic valve replacement (AVR). Mortality rates have been stable around 3 to 4% for single AVR in spite of the ever increasing average patient age and associated comorbidities. The choice of prosthesis in the aortic position has shifted with the majority of diseased valves being replaced by a bioprosthesis today . In contrast to coronary surgery where the decline in the number of operations has been accompanied by a rising procedural volume of percutaneous coronary interventions (PCI) since the late 1990s, valve surgery is still expanding.
