Background. We ­review ­twelve-­year expe­ri­ence ­with cor­o­nary reop­er­a­tions so as to bet­ter iden­ti­fy indi­ca­tions, tech­niques and ­results.
Methods. Between January 1986 and March 1998, 240 cor­o­nary reop­er­a­tions (228 ­redux, 12 tri­dux) ­were per­formed. There ­were 223 ­male and 17 ­female ­patients, ­with a ­mean age of 63.6±7.9 ­years at the ­time of reop­er­a­tion. Mean ­time inter­val ­between oper­a­tions was 10±4.8 ­years. Symptomatology con­sist­ed of: ­stable recur­rent angi­na (40%), ­unstable (57%), or con­ges­tive ­heart fail­ure (3%). Pathological fea­ture of the pri­mary ­grafts was impli­cat­ed in 95% of cas­es and ather­o­ma ­sole pro­gres­sion ­over ­native net­work in 5% of cas­es. During reop­er­a­tions 521 (2.2±0.8/­patient) ­bypass [­venous (40%), arte­ri­al (60%)] ­were per­formed as ­well as 15 asso­ciat­ed pro­ce­dures.
Results. Operative mor­tal­ity rep­re­sent­ed 10% (n=24). Causes of ­death includ­ed ­infarct (7), ­left ven­tric­u­lar fail­ure (12), ­rhythm dis­or­ders (2), med­i­as­tin­itis (1) and mul­ti-­organ fail­ure (2). Mortality ­risk fac­tors ­were oper­a­tion ­date (16.6% ­before 1992 and 7.4% ­after, p=0.03), age (13.1% ­after 60 ­years old, 2.7% ­before, p=0.01) ­time inter­val ­between inter­ven­tion (12% ­after 8 ­years, 4% ­before, p=0.05) and ante­ro­grade car­di­o­ple­gia ­only (11.8% ver­sus 4.5% ­when a com­bined ante­ro­grade and ret­ro­grade ­access was ­used, p=0.06). Morbidity was 31% (71/240). Among the sur­vi­vors 169 ­patients (78%) did not expe­ri­ence any com­pli­ca­tion.
Conclusions. Thanks to a bet­ter med­i­co-sur­gi­cal man­age­ment, the mor­tal­ity ­rate of cor­o­nary reop­er­a­tions is stead­i­ly decreas­ing.
