Background: Transfusion in acute aortic syndromes has been studied in a limited fashion. We sought to describe contemporary transfusion practice for root replacement in acute (Stanford) type A aortic dissection.
Methods: The Society of Thoracic Surgeons Adult Cardiac Surgery Database was interrogated to identify patients who underwent primary aortic root replacement for acute (Stanford) type A aortic dissection (July 2014 to June 2017). Patients (n = 1558) were stratified by type of root replacement. Multivariate regression was used to determine those variables associated with transfusion and postoperative morbidity.
Results: Transfusion was required in 90.5% of cases (n = 1410). Operative mortality for all patients was 17.3% (261 deaths). Intraoperative red blood cell transfusion portended reduced short-term survival (odds ratio [OR] 2.00, P = .025). Massive postoperative transfusion was associated with prolonged ventilation (OR 13.47, P < .001), sepsis (OR 4.13, P < .001), and new dialysis-dependent renal failure (OR 2.43, P < .001). Women were more likely to require transfusion (OR 3.03, P < .001), as were patients who had coronary artery bypass (OR 1.57, P = .009), and those in shock (OR 2.27, P < .001). Valve-sparing aortic root replacement was associated with reduced transfusion requirements vs composite roots. Institutional case volume was not appreciably correlated with transfusion.
Conclusions: Most patients undergoing root replacement for aortic dissection require blood products. Composite root replacement is associated with a greater likelihood of transfusion than a valve-sparing operation. Transfusion independently foreshadows greater operative mortality.

Objective: Valve selection in acute type A aortic dissection (ATAAD) requiring aortic root replacement is challenging given the clinical acuity, unknown patient preferences, risk of surgical bleeding, and limited life expectancy. We sought to identify long-term outcomes of mechanical versus bioprosthetic aortic root replacement in young patients with ATAAD.
Methods: Retrospective review of our institution's database of ATAAD was conducted to identify patients aged 65 years and younger who underwent mechanical Bentall (mech-Bentall) or bioprosthetic Bentall (bio-Bentall) for ATAAD from 2002 to 2022.

Objectives: Loeys-Dietz syndrome comprises genetically discrete subtypes of varying clinical severity. This study integrates longitudinal Loeys-Dietz syndrome clinical outcomes after aortic root replacement with transcriptomic analysis of aortic smooth muscle cell dysregulation to investigate mechanisms governing this subtype-specific aortic vulnerability.
Methods: Single institutional experience with aortic root replacement for nondissected aneurysm in patients with Loeys-Dietz syndrome was reviewed for midterm survival and distal aortic events (subsequent aortic intervention, aneurysm, or dissection).

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.
