Aortic Valve-Sparing Surgical Techniques

Aortic valve-sparing surgery encompasses a range of operations designed to address aneurysmal and degenerative disease of the aortic root while conserving the patient’s native valve leaflets and sub-valvular apparatus. The two principal strategies are reimplantation, in which native leaflets are secured within a synthetic graft, and remodelling, which reshapes the root to restore physiological geometry. Contemporary techniques often incorporate geometric annuloplasty rings and tailored leaflet repair, permitting precise correction of coaptation deficits, particularly in bicuspid valve pathology. External support devices, such as personalised mesh sleeves, offer less invasive reinforcement for root aneurysms, whereas the Florida Sleeve procedure simplifies root restoration without complete valve excision. Refinements in preoperative imaging, three-dimensional modelling and intraoperative echocardiography have enhanced patient selection, procedural planning and quality assurance. Minimally invasive access approaches, extending the benefits of the David reimplantation procedure, reduce surgical trauma without compromising durability. Outcomes data demonstrate excellent long-term survival, low reintervention rates and superior quality of life relative to prosthetic replacement, underpinning the global adoption of valve-sparing strategies as a durable and patient-centred standard in aortic root surgery. As populations age and the demand for durable, anticoagulant-free solutions grows, valve-sparing techniques have assumed central importance across surgical centres worldwide, driving ongoing research into device innovation and reproducibility of outcomes.

Recent comparative analyses have demonstrated that personalised external aortic root support and valve-sparing root replacement yield equivalent mid-term survival and functional valve competence, offering tailored options for patients with connective tissue disorders and root aneurysms. In a multicentre propensity-matched study, valve-sparing root replacement was associated with superior five-year survival and fewer valve-related adverse events than composite valve-graft replacement, reinforcing its role where durable repair is feasible. Additionally, minimally invasive reimplantation via a reduced sternotomy has shown early and mid-term outcomes comparable to full sternotomy, highlighting the importance of meticulous haemostasis and patient selection to extend valve-sparing benefits with reduced surgical trauma.

Technical terms

Aortic root: The section of the ascending aorta to which the aortic valve leaflets attach.

Valve-sparing root replacement (VSRR): A procedure preserving the native valve by reimplanting or remodelling the root within a graft.

Personalised external aortic root support (PEARS): A custom-made mesh device applied externally to reinforce a dilated root and prevent aneurysm expansion.

Aortic regurgitation: A condition in which the aortic valve fails to close fully, allowing reverse flow of blood into the left ventricle.

Annuloplasty: The surgical reinforcement or resizing of the valve annulus to restore leaflet coaptation and valve competence.
