Cardiac reoperations in octogenerians.
OBJECTIVE
In recent years, satisfactory outcome of primary cardiac operation in octogenerians and increased ageing of cardiac surgical population in western hospitals have led to increased expectations and referrals for reoperation. Outcome of reoperation in this aged subset was analysed.


METHODS
Consecutive 18 octogenerians (mean age 81.2 years, 10 men, eight women) undergoing cardiac reoperations from November 1989 through August 1998 were retrospectively reviewed.


RESULTS
They represented 6.2% of all octogenerian cardiac surgical patients and 2.7% of all reoperations during the same period. Mean preoperative NYHA class was 3.4 and Parsonnet score was 29.4. The interval to reoperation was 114.5+/-11.96 (4-188) months. Priority was urgent in 11 and elective in seven patients. The procedures included four AVRs, five MVRs (including two associated TVAs), six CABGs and one each of MVR with CABG, AVR with CABG and AVR, MVR and CABG. Average graft/patient was 2.3. Mean ICU stay was 4.6+/-1.5 (1-28) days. There was one hospital death (5.5%) on 18 pod after MVR in an 83-year-old woman. Mean postoperative stay was 20.2+/-5.13 (8-93) days. There were three late deaths (17.6%)--at 32 months after MVR, at 44 and 63 months after CABG. Long-term survivors were 90% among men and 50% among women who were followed up for 42.7+/-6.9 (9-93) months. Mean Karnofsky score in survivors at 1 year of follow-up was 78.5+/-2.9. Despite continued medication in all survivors, mean current NYHA is 1.9 and most have improved lifestyle.


CONCLUSIONS
Satisfactory outcome may be expected after cardiac reoperations in highly selected octogenerians. However, increased procedural risks, complications, hospital stay and slower convalescence during early follow-up may be anticipated, and will indicate very careful screening. These results indicate a need to reconsider the treatment policy in primary operation with regard to choice of graft conduits and prosthetic valves in other elderly patients.
