[Surgical treatment of aortic valve disease in old age].

In terms of long-term survival and quality of life, excellent results with aortic valve replacement (AVR) can also be achieved in patients older than 70 years of age. An indication for this procedure is given in symptomatic patients with significant aortic valve stenosis, patients with severe acute aortic insufficiency (AI), those with signs of cardiac insufficiency but still normal left ventricular function, and asymptomatic AI patients with an ejection fraction of less than 50% and/or an end-diastolic LV diameter (EDD) of more than 75 mm or an end-systolic diameter (ESD) of more than 55 mm. Many patients with a heart defect in need of surgical treatment also have CAD as well, in which case a bypass should be performed at the same time. For AVR, both mechanical and biological prostheses are available, the latter being regarded as the method of choice in patients aged over 70. The mechanical variant requires life-long anticoagulation therapy with phenprocoumon.
