Introduction: The aim of this study is to compare various modifications of Bentall procedure for early complications and long-term follow-up results.
Patients and Methods: One hundred forty-nine patients underwent proximal aortic root replacement with composite valve-conduit graft between 1995 and 2014. Bentall procedure and its modifications (Cabrol procedure and hemi-inclusion) were evaluated for short- and long-term outcomes. Patients with concomitant procedures, arch repair, or valve-sparing procedures were excluded from the study.
Results: In this study, 64 patients have met the inclusion criteria: 20 patients were included in the button Bentall group, 32 patients in the hemi-inclusion Bentall group, and 12 patients in the Cabrol group. Preoperative patient demographics were similar in all groups. The hemi-inclusion technique had better early outcomes, including less intraoperative blood transfusion, short cardiopulmonary bypass, and better in-hospital mortality rates (p< 0.05). However, the long-term all-cause mortality rates did not differ between the groups (p> 0.05).
Conclusion: The hemi-inclusion Bentall technique might be used as a safe alternative approach for various aortic root diseases due to better hemostatic properties and lesser in-hospital mortality rates.
