Objective: To evaluate the early postoperative morbidity, mortality, and prosthetic conduit function of patients who underwent aortic root replacement using a prefabricated bioprosthetic aortic valved conduit.
Methods: Single-center retrospective review of 124 consecutive adult patients who underwent aortic root replacement with a certified prefabricated bioprosthetic aortic valved conduit from 2021 to December 2023.
Results: Indications for operation were aortic aneurysms (n = 92), endocarditis (n = 12), deterioration of prior valve prosthesis (n = 13), and aortic dissection (n = 6).

Although generally considered harmless commensals or beneficial probiotics, species can act as opportunistic pathogens under certain clinical conditions. We describe a case of high-grade bacteremia in a 59-year-old man with a history of aortic root dilation status post Bentall procedure and bioprosthetic aortic valve replacement. The suspected source was recent dental instrumentation.

Introduction: Prosthetic valve endocarditis following aortic root replacement (ARR) typically necessitates redo-ARR, which involves complete graft removal, extensive aortic root dissection, and coronary reimplantation. This highly invasive procedure carries substantial surgical risk, including high operative mortality. In select high-risk patients without evidence of prosthetic graft infection, alternative surgical strategies may reduce procedural complexity and improve outcomes.

Kommerell's diverticulum (KD) combined with a right-sided aortic arch (RAA) and an aberrant left subclavian artery (ALSA) is a rare congenital vascular anomaly causing significant compressive dysphagia. Treatment options, including open surgery, thoracic endovascular aortic repair and hybrid approaches, are debated due to anatomical complexities. We report a 48-year-old female with dysphagia from symptomatic KD, RAA and ALSA, clearly delineated by preoperative computed tomography angiography.

Complete detachment of the aortic root following a Bentall procedure is an exceptionally rare complication. The vast majority of reported cases are secondary to prosthetic valve endocarditis or underlying vasculitis. Currently, the most reliable treatment for aortic root dehiscence-particularly in the context of prosthetic valve endocarditis-is repeat root replacement, typically via a second Bentall procedure or with the use of a homograft or allograft.
