HEart Surgery In Atrial Fibrillation and Supraventicular Tachycardia (HEIST)

Atrial fibrillation is the most common cardiac arrhythmia, the incidence of which increases drastically with age. As more and more elderly patients undergo heart surgery, the proportion of patients in this population will increase. Atrial fibrillation has been shown to be a poor prognostic factor in several surgical situations. The aim of our study was to assess long-term mortality among patients with preoperative AF under various cardiac surgery settings, with a particular emphasis on the strategy of coronary revascularization.
