Why the study?
What is the incidence and what are the predisposing factors for perioperative ventricular arrhythmias in patients undergoing cardiac surgery for acquired valvular diseases?
Population
71 consecutive patients undergoing cardiac surgery for acquired valvular diseases
Design
Cohort
Follow-up
4 to 10 weeks after operation

Monitor closely for arrhythmias on operative day after valvular surgery; magnesium cardioplegia was associated with fewer early VPCs but leaves open need for RCTs.
What is the incidence and what are the predisposing factors for perioperative ventricular arrhythmias in patients undergoing cardiac surgery for acquired valvular diseases?
Perioperative ventricular arrhythmias peak on the day of valvular surgery and correlate with preoperative arrhythmias and postoperative LV dysfunction, while magnesium-containing cardioplegia may reduce their incidence.
Shigemitsu et al. (1991) studied this question.
