Emergency redo surgery is rare, but may be required in patients with conditions such as endocarditis, unstable angina and acute aortic dissection. To date there are no published data on the outcome of these difficult patients. Prospective consecutive data were collected from a single institution on 65 patients (51 male) undergoing coronary artery bypass grafts (27), mitral valve replacement or repair (13), aortic valve replacement (7), aortic surgery (13), and other (combined procedures) (5). Indications for surgery were unstable angina (12), endocarditis (11), resuscitation/catheter lab complications (11), torn prosthetic leaflet (6), aortic dissection (4), paraprosthetic leak (2), other (19). Mean ITU stay was 45 h (0–284) and hospital stay was 13.3 days (0–68). There were 14 intra-operative deaths and 14 further in-hospital deaths (overall mortality 43%). Predicted mortality rates were 26% (Parsonnet), 11% (EuroSCORE) and 31% (EuroSCORE logistic). Mean hospital cost per patient was euro18,299 (or Euro32,147 per hospital survivor). In conclusion, the mortality in these difficult patients is very high, however, often no other treatment option is available. More sophisticated models, such as EuroSCORE logistic, may allow better prediction of risk in very high risk cases.
