Objectives: Patients with ischemic ventricular arrhythmia (IVA) in the form of
fibrillation or tachycardia represent a surgical challenge. Evidence in the
literature suggests that ventricular arrhythmia threatens survival even after
cardiac surgery. We aim to review the results of our patients presenting with
IVA with regard to short and long term outcome following cardiac surgery.
Methods: This was a retrospective study of data entered prospectively into our
cardiac surgical database between January 1999 and September 2015. A total of
9609 patients underwent Cardiac Surgery which included 54 patients after
surviving IVA. The short-and long-term outcomes were compared to a propensity matched group.
Actuarial survival was calculated using Kaplan Meier analysis. Results: The 54 study group patients were propensity matched on a 1:2 basis with
a control group of non-IVA (n=108). The baseline preoperative
characteristics and risk factors were similar between the 2 groups and all
cases underwent CABG only. Univariate analysis showed pacing postoperatively
