ObjectivesAlthough rare, life-threatening complications requiring emergency cardiac surgery do occur after diagnostic and therapeutic cardiac catheterization procedures. The operative mortality has been persistently reported to remain high. The purpose of this observational study was to evaluate and report the outcomes, with particular emphasis on early mortality, of these risky operations that were performed in a single highly specialized cardiac centre.MethodsBetween June 1997 and August 2007, 100 consecutive patients, 13 after diagnostic complicated cardiac catheterization (0.038% of 34,193 angiographies) and 87 after crashed percutaneous coronary intervention (PCI; 0.56% of 15,544 PCIs), received emergency operations at the Feiring Heart Center. In the same period, 10,192 other patients underwent open cardiac surgery. Early outcome data were analysed and compared between the cohorts. Follow-up was 100% complete.ResultsThe preoperative status of the 100 patients was that 4 had ongoing external cardiac massage, 24 were in cardiogenic shock, 32 had frank enduring ST-segment infarction but without shock and 40 had threatened acute myocardial infarction. There was 1% (1 patient) 30-day mortality in the study group, which is equal (0.9%, P=0.60) to that of all other operations. Postoperative myocardial infarction and prolonged ventilator use were significantly higher in the crash group, whereas the rate of stroke, renal failure, reopening for bleeding and mediastinitis were similar between the groups.ConclusionsWith rapid transfer to an operation room, minimizing the time of warm myocardial ischaemia, and by performing complete coronary revascularization, it is possible to obtain equally low operative mortality in patients with life-threatening cardiac catheterization-associated complications, as is the case with open cardiac operations in general.
