Key Points

To review surgical principles, anatomical geometry, and standardized reconstructive techniques for aortic valve repair and valve-sparing interventions in aortic regurgitation.
Reviewed surgical management strategies for aortic regurgitation linked to leaflet pathology and aortic root dilation.
Assessed anatomical normalization at the basal ring, sinotubular junction, and aortic cusps.
Aortic valve competence is restored by systematically normalizing the geometry of the basal ring, sinotubular junction, and leaflets.
Aortic root remodeling and valve reimplantation represent standard surgical options for managing dystrophic root enlargement.
Valve preservation avoids long-term complications typically associated with prosthetic valve replacement.

Structured PICO

P

Population

Patients with aortic regurgitation and/or significant dilation of the ascending aorta.

I

Intervention

Aortic valve repair and valve-sparing aortic root replacement (VSARR) procedures, including aortic root remodeling and aortic valve reimplantation.

Aortic valve repair and valve-sparing procedures are recommended alternatives to valve replacement for suitable patients, offering good long-term outcomes and avoiding the need for lifelong anticoagulation.

Limitations

Lack of randomized controlled trials comparing these procedures with aortic valve replacement and the Bentall operation.
Available retrospective studies are highly heterogeneous regarding inclusion criteria, surgical techniques, and follow-up duration.
The procedures are technically demanding and associated with a longer learning curve, requiring specialized centers.
Lack of randomized studies comparing these procedures with aortic valve replacement
Available retrospective studies are highly heterogeneous regarding inclusion criteria, surgical techniques, and follow-up duration

Implication

May support valve repair in aortic regurgitation; leaves open need for randomized confirmation.

Abstract

ZĂĄchovnĂŠ operace a plastiky aortĂĄlnĂ chlopnÄ pĹedstavujĂ moĹžnost chirurgicky obnovit kompetenci nedomykavĂŠ aortĂĄlnĂ chlopnÄ a vyhnout se rizikĹŻm, kterĂĄ provĂĄzejĂ nemocnĂŠ v pĹĂpadÄ nĂĄhrady chlopnÄ. ĂspÄĹĄnĂŠ provedenĂ rekonstrukce vyĹžaduje plnĂŠ porozumÄnĂ statickĂŠ i dynamickĂŠ geometrii aortĂĄlnĂ chlopnÄ a aortĂĄlnĂho koĹene. AortĂĄlnĂ regurgitace vychĂĄzĂ z malpozice patologicky zmÄnÄnĂ˝ch chlopennĂch cĂpĹŻ, souÄasnÄ je velmi Äasto spojena s dilataÄnĂm postiĹženĂm aortĂĄlnĂho koĹene a vzestupnĂŠ aorty. Technika chirurgickĂ˝ch intervencĂ pro aortĂĄlnĂ nedomykavost proĹĄla historickĂ˝m vĂ˝vojem a v souÄasnĂŠ dobÄ spÄje ke zjednoduĹĄenĂ a standardizaci jednotlivĂ˝ch krokĹŻ aortĂĄlnĂ plastiky. ZĂĄkladnĂm principem je normalizace morfologickĂŠho nĂĄlezu na Ăşrovni bazĂĄlnĂho prstence, sinotubulĂĄrnĂ junkce a vlastnĂch cĂpĹŻ aortĂĄlnĂ chlopnÄ. Remodelace aortĂĄlnĂho koĹene a reimplantace aortĂĄlnĂ chlopnÄ zĹŻstĂĄvajĂ standardem rekonstrukce v pĹĂpadÄ dystroficky dilatovanĂŠho aortĂĄlnĂho koĹene.
