Revisiting ascending aortic resection in the elective valve-sparing root replacement: assessing the benefits and necessity of hemiarch replacement at three centres.
Eur J Cardiothorac Surg
January 2025
Division of Cardiovascular Surgery, Department of Surgery, University of Pennsylvania, Philadelphia, PA, USA.
Objectives: The aim of this study was to determine the indication and optimal timing for performing a hemiarch procedure in patients undergoing valve-sparing root replacement (VSRR).
Methods: We conducted a retrospective study on 986 patients undergoing VSRR at three tertiary care centres. Inclusion criteria were all patients undergoing elective VSRR.
Valve-sparing versus bio-Bentall aortic root replacement in patients aged 60-75 years: Survival, Reintervention and Aortic Regurgitation.

Department of Cardiac Surgery, IRCCS Policlinico San Donato, Italy.
Background: Valve-sparing root replacement(VSRR) with the David technique is an established therapy for aortic root pathology in young patients. The aim of this study was to evaluate short and long-term outcomes between VSRR and aortic root replacement(ARR) with a biological-valved conduit in sexagenarians.
Methods: A multicenter retrospective review from 2002-2022 identified 299-sexagenarians undergoing aortic root surgery, among whom 82(27.

Background And Objective: In clinical practice, valve-sparing aortic root replacement surgery primarily addresses left ventricular dysfunction in patients due to severe aortic regurgitation, but there is controversy regarding the choice of surgical technique. In order to investigate which type of valve-sparing aortic root replacement surgeries can achieve better blood flow conditions, this study examines the impact of changes in the geometric morphology of the aortic root on the hemodynamic environment through numerical simulation.
Methods: An idealized model of the aortic root was established based on data obtained from clinical measurements, including using the model of the aortic root without significant lesions as the control group (Model C), while using surgical models of leaflet reimplantation with tubular graft (Model T), leaflet reimplantation with Valsalva graft (Model V), and the Florida sleeve procedure (Model F) as the experimental groups.
Transcatheter aortic valve replacement for aortic regurgitation following valve sparing root replacement: a case series.
Eur Heart J Case Rep

Institute of Cardiovascular Sciences, University of Birmingham, Birmingham B15 2TT, UK.
Background: Valve sparing aortic root replacement (VSARR) is a treatment for aortic root dilatation and aortic regurgitation (AR), which preserves the aortic valve. However, AR may recur, and redo surgery often carries high risk. Transcatheter aortic valve replacement (TAVR) can be performed but there is a paucity of literature to guide procedural planning.

Objectives: While valve-sparing aortic root replacement (VSRR) has demonstrated satisfactory outcomes, its utility in a reoperative sternotomy setting remains uncertain. This study evaluates the perioperative safety and long-term durability of reoperative sternotomy VSRR.
Methods: All consecutive VSRR at two centers from 2005-2020 were included.
