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).
