Coronary and valvular surgery in elderly patients (greater than 70 years).
During 1949-1964 only 22% of our patients (n = 6807) undergoing cardiac surgery were older than 40 years. Up to 1970 no patients older than 60 years underwent open-heart surgery in our institution. Between 1970 and 1978 an open-heart procedure was performed in 174 patients older than 60 years (4.5%). The hospital mortality was 18.3%. During the following years the operative indication for aged patients became more liberal, and the operative risk decreased distinctly. Already in 1983 the percentage of aged people rose to 24.1% of our extracorporeal circulation group (n = 1111). In a retrospective study (1979 to 1985) a total of 6855 heart procedures using ECC were evaluated. In total 196 patients (2.9%) were 70 years and older. Valvular replacement was performed in 95 cases. (AVR n = 67, MVR n = 13, DVR n = 15) resulting in a hospital mortality of 10.9% (n = 10). Revascularisation for coronary heart disease including resection of ventricular aneurysms was necessary in 64 patients with an early mortality rate of 3.1% (n = 2). The highest risk group consisted of combined coronary and valvular procedures (n = 33) with a mortality rate of 12.1% (n = 4). There was one case each of ASD II, HOCM, left atrial myxoma, and massive pulmonary embolism with cardiogenic shock: only the latter patient died, from cerebral hypoxia postoperatively. Thus the hospital mortality in this age group (n = 196) was 9.1% (n = 17).(ABSTRACT TRUNCATED AT 250 WORDS)
