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.
