Article Abstract
Objective: To evaluate the early outcomes of a modified bio-Bentall operation using a rapid deployment valve (RDV) in high-risk patients, focusing on procedural efficacy, survival rates, and complications.
Methods: A retrospective review of 11 consecutive patients who underwent the modified bio-Bentall operation with an RDV between January 2018 and December 2022 was conducted. Kaplan-Meier survival analysis was used to determine survival rates. Patients' baseline characteristics, operative details, and postoperative outcomes were reviewed.
Results: The median patient age was 71 years. Most patients presenting with high-risk conditions and significant comorbidities, including inflammatory conditions, chronic lung diseases, and advanced cardiac dysfunction. The median EuroSCORE II was 10.03%. The median aortic cross-clamping and cardiopulmonary bypass times were 73.0 minutes and 99.0 minutes, respectively. No early mortalities or reoperations occurred. Two patients (14.3%) required extracorporeal membrane oxygenation support because of low cardiac output and arrhythmias, and 3 patients (23.1%) required permanent pacemaker insertion. No paravalvular leakage or valve detachment was observed during follow-up. The 1-year survival rate was 90.9%, and the 3-year survival rate was 54.5%. Six patients died during a median follow-up of 35 months, from causes including respiratory complications, gastric cancer, and undetermined factors.
Conclusions: Our initial experience with the modified bio-Bentall operation using an RDV shows favorable early outcomes in relatively high-risk patients. Further validation with larger datasets and long-term follow-up is needed to validate these results.

Mitral-aortic intervalvular fibrosa pseudoaneurysm is a rare but potentially fatal complication, most commonly arising from infective endocarditis or a prior cardiac operation. Rupture of a mitral-aortic intervalvular fibrosa pseudoaneurysm constitutes a surgical emergency and presents considerable technical challenges, with reported early mortality rates between 20% and 30%. We report the case of a high-risk 72-year-old man with a history of two prior cardiac operations who presented with a contained rupture of a mitral-aortic intervalvular fibrosa pseudoaneurysm and an aortic root abscess.

A 59-year-old male underwent Bio-Bentall + total arch replacement with a frozen elephant trunk for acute type A aortic dissection before at another hospital. He was diagnosed as mediastinitis and previous graft infection, followed by wound closure with omental flap installation. However, the recurrent graft infection from the aortic root to the FET in the descending aorta was diagnosed by 18-fluorodeoxyglucose positron emission tomography.

Objectives: To evaluate the early and late outcomes of the modified Bentall procedure with the flanged technique.
Methods: We reviewed the medical records of 63 patients who had undergone root replacement by the modified Bentall procedure at our institute between January 2001 and December 2018. In most cases, we adopted a composite graft constructed with a mechanical valve or bioprosthesis and a Dacron graft by the flanged technique.

The present study evaluated our modified technique for placing a valve one size larger for Biological Bentall (Bio-Bentall) with a stented valve using a double sawing ring technique with a comparison to classical Bio-Bentall with a stent-less valve. Between December 2001 and July 2017, 44 patients (10 stent-less and 34 stented) with Bio-Bentall were included in this study. The early and mid-term surgical outcomes and re-operation free rates, including the structural valve deterioration (SVD) rate, were investigated.
