The cases of 135 consecutive elderly patients 70 years old or older who had
valve replacement and related surgical procedures from October, 1977,
through April, 1982, were reviewed. There were 75 men and 60 women. The
mean left ventricular ejection fraction was 50.16 +/- 5%. The overall
operative mortality was 8% (11 patients). The early operative deaths were
related mainly to cardiac failure, low cardiac output, sepsis, and renal
and multiorgan failure. To assess the operative risk, these 135 patients
were compared with 312 younger patients (less than 70 years old) who had
undergone similar procedures during the same period. The operative
mortality in this group was 5.2% (16). In-hospital complications included
arrhythmia (13%), psychosis (7.4%), respiratory failure (6.7%), renal
failure (6.7%), cerebrovascular accident (5.2%), myocardial infarction
(4.4%), and reoperation for bleeding (2.2%). Wound dehiscence occurred in
1.5% of the patients, and pulmonary emboli and sepsis developed in 0.7%. Of
these complications, only the incidence of cerebrovascular accident
appeared to be more common in the elderly group (5.2% versus 2.8%), but it
had no statistical significance (p = 0.18). A follow-up of 3,892
patient-months was completed in 98.4% of the survivors. There were 8 late
deaths (6.4%). Six were related to the valve or to ongoing cardiovascular
disease. Thirty-four patients subsequently required medical attention: 4
had bleeding because of the anticoagulant; 3 required a blood transfusion;
and 27 were hospitalized. Six were admitted for related cardiac conditions
and 7, for observation of other conditions; 14 underwent surgical
procedures not related to the cardiovascular system.(ABSTRACT TRUNCATED AT
