FORTUNATO, Germán A. et al. Multinational and Cross-Sectional Survey on Valve-Sparing Aortic Replacement Controversies. Rev. argent. cardiol. [online]. 2023, vol.91, n.2, pp.125-137. ISSN 1850-3748.


: The valve-sparing aortic root replacement (VSAR) has been established as a successful procedure for aortic root aneurysms, Marfan's syndrome, bicuspid valves, and aortic dissections. However, there is a need for a consensus opinion regarding key aspects of VSAR.


: A literature review was performed regarding the most frequent debates and controversies in VSAR. An online survey was developed based on this information, and sent to surgeons with known expertise in VSAR regarding their opinion on patient-related factors, technical aspects, echocardiography, research, training, and the future of VSAR.


: Twenty surgeons completed the survey. The reduction of left ventricular ejection fraction was considered a contra indication to VSAR when severe by 14/20 surveyed. The aortic annulus diameter cutoff point for the remodeling was heterogenous among participants. All of them felt that VSAR is safe for the Marfan´s syndrome population and bicuspid valves. For type A dissections, 11/20 preferred this procedure only in young patients. Regarding to graft sizing, the height of the interleaflet triangle (8/20) and the sino-tubular diameter (7/20) were the more frequent considered parameters. Surgeons reported a 7% of failure rate, leading to conversion to Bentall surgery, and a 26% change of strategy intraoperatively. A minimally invasive approach was not considered to improve results. Most of the surgeons agreed that VSAR should be performed by high-experienced surgeons.


: The VSAR has been accepted as a treatment option for the aortic root´s aneurysms, and even though there is still not possible to reach a final consensus, a valuable experience from the most relevant surgeons in the field is presented.
