Background: The study aim was to identify factors affecting early mortality in valvular reoperations.

Methods: Between January 1993 and December 2011, a total of 693 patients who had undergone valvular reoperations due to problems with previously implanted mechanical and biological valves, new valve degeneration or valve failure after a reconstructive procedure was included in the study. Factors affecting early mortality were identified by the examination of preoperative and perioperative data, using multivariate analysis.

Results: The average age of the patients was 44.9 years. For all patients, overall hospital mortality was 15.9%, while hospital mortality rates were 12.9% and 35.3% for elective operation and urgent/emergency treatment, respectively. Factors affecting early mortality in the multivariate analysis were longer total perfusion time (>120 min, p = 0.001), emergency or urgent treatment (p = 0.001), and the presence of preoperative renal failure (p = 0.001).

Conclusions: Mortality for elective patients in valvular reoperations was within an acceptable range. Total mortality was dependent on a high mortality level of emergency/urgency of the cases. The use of a well-defined protocol in valvular reoperations may decrease hospital mortality.
