3.2 Operative parameters
Operative procedures and intraoperative findings are shown in Table 2.
In this study, 75% of patients underwent TAVI through the trans-femoral
approach, 19% through the trans-apical, 3%, through the
trans-subclavian, and 2% through the ascending aorta. A
balloon-expandable valve was implanted in 72% of patients, while a
self-expandable valve was implanted in 28%. The interventional
approach, type of prosthetic valve, procedure time, and blood
transfusion rates were statistically equivalent between the two groups.
