Patient characteristics and operative data
The mean age of the patients was 65.0±14.2 years, and 92 (52.9%) men
were included in the study. Moreover, six (4.0%) patients had a history
of stroke (Table 1).
The procedures comprised single valve surgeries (n=143, 81.3%), double
valve surgeries (n=20, 11.5%), and other cardiac surgeries (n=11,
6.3%). Single valve surgeries comprised aortic valve replacements
(n=66, 37.9%) and mitral valve procedures (n=77, 44.2%). The mitral
valve procedures included mitral valve repairs (n=69, 39.6%) and mitral
valve replacements (n=8, 4.6%). The double valve procedures comprised
aortic and mitral valve surgeries (n=4, 2.3%) and mitral and tricuspid
valve surgeries (n=16, 9.2%).
The median times taken to perform aortic cross-clamping and CPB were
102.9±37.5 and 132.7±38.6 min, respectively (Table 2).
