3.3 Early outcomes
No inpatient deaths occurred in both the groups. The hospital stay was significantly longer in group N than in group Y (19±32.1 days vs. 12.1±9.3 days, p=0.04). However, the incidence of any complication, including the need for pacemaker implantation, paravalvular leakage, cerebral infarction, and acute type B dissection, was equivalent in the two groups (Table 3).
We assessed postoperative cardiac function using transthoracic echocardiography (Supplemental Figure 1). The aortic valve area was significantly increased in both groups. Peak systolic velocity and mean pressure gradient were significantly decreased in both groups. There were no significant differences in echocardiographic findings between the two groups.
