Surgical aortic valve replacement cohort
Baseline patients’ characteristic and post-operative results for SAVR
cohort (n=8340) are given in Table 2. Similar to the mitral
cohort, patients in the MetS group (n=887), when compared to the no-MetS
(n=7453) were older, with higher proportion of female sex and with
greater burdens of comorbidities.
There was no difference in term of proportion of patients operated with
minimally invasive approach (47.2% vs. 51.1%, p=0.20). Both
cardiopulmonary bypass (79 (33) min vs. 75 (35) min, p=0.005) and cross
clamp time (62 (27) min vs. 60 (28) min, p=0.07) were longer in the MetS
than in the no-MetS.
Mets group, compared to no-MetS, had increased number of patients who
received at least two units of RBC (40.2% vs. 27.7%,
p<0.001) and experienced post-operative renal failure (10.1%
vs. 5.6%, p<0.001). ICU stay (2 (2) days vs. 2 (1) days,
p=0.007) was longer in the MetS group.
Overall LOS was also longer in the MetS group (10 (6) days vs. 10 (5)
days, p=0.002) (Figure 1 A/B/C ). However, in-hospital mortality
did not differ between the two groups (1.8% vs. 2.1%, p=0.65)
