The average length of the postoperative stay was 7.8 ± 3.7 days. The 30-day and in-hospital mortalities were 0%. Complete atrioventricular block occurred in three cases (so permanent pacing was needed), complete left bundle branch block in 44, intraventricular conduction delay in 18, complete right bundle branch block (RBBB) in two, transient renal dysfunction in two (so hemodialysis was needed) and transient intra-aortic-balloon-pumping was needed in two. No other severe complications were observed during hospital stay.
