Observed Mortality and Postoperative Outcomes
Table 3 indicates that the 30-day mortality rate was higher
(p = 0.01) in the MVR group, consistent with their increased
preoperative risk profile (Table 1). In patients undergoing
replacement, the prevalence of sepsis (p = 0.03), pulmonary
complications (p = 0.0008), and surgical re-exploration (p = 0.04), was
higher than in the repair group. There was no difference between groups
concerning perioperative MI, pacemaker insertion, atrial fibrillation,
acute kidney injury, sternal wound infection, or permanent neurological
events (Table 3). However, MVR patients had significantly
higher resource utilization, including higher duration of mechanical
ventilation (p < 0.0001), longer intensive care unit stay (p =
0.03), and hospital stay (p < 0.0001) than the repair group
(Table 3).
