Aortic valve performance after remodelling versus reimplantation in a propensity-matched comparison. Eur J Cardiothorac Surg 2024; 66:ezae234. [PMID: 39102871 DOI: 10.1093/ejcts/ezae234] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 05/09/2024] [Accepted: 06/10/2024] [Indexed: 08/07/2024] Open
Abstract
OBJECTIVES Both aortic root remodelling and aortic valve (AV) reimplantation have been used for valve-sparing root replacement in patients with aortic root aneurysm with or without aortic regurgitation. There is no clear evidence to support one technique over the another. This study aimed to compare remodelling with basal ring annuloplasty versus reimplantation on a multicentre level with the use of propensity-score matching. METHODS This was a retrospective international multicentre study of patients undergoing remodelling or reimplantation between 2010 and 2021. Twenty-three preoperative covariates (including root dimensions and valve characteristics) were used for propensity-score matching. Perioperative outcomes were analysed along with longer-term freedom from AV reoperation/reintervention and other major valve-related events. RESULTS Throughout the study period, 297 patients underwent remodelling and 281 had reimplantation. Using propensity-score matching, 112 pairs were selected and further compared. We did not find a statistically significant difference in perioperative outcomes between the matched groups. Patients after remodelling had significantly higher reintervention risk than after reimplantation over the median follow-up of 6 years (P = 0.016). The remodelling technique (P = 0.02), need for decalcification (P = 0.03) and degree of immediate postoperative AV regurgitation (P < 0.001) were defined as independent risk factors for later AV reintervention. After exclusion of patients with worse than mild AV regurgitation immediately after repair, both techniques functioned comparably (P = 0.089). CONCLUSIONS AV reimplantation was associated with better valve function in longer-term postoperatively than remodelling. If optimal immediate repair outcome was achieved, both techniques provided comparable AV function.

Abstract
Aortic root aneurysms are one of the most common aortic root diseases, involving the aortic valve, aortic sinus, bilateral coronary arteries, and part of the ascending aorta. It is a life-threatening aortic disease with a high mortality rate of approximately 90%, due to aortic aneurysm rupture. Aortic valve insufficiency is one of the most common complications of aortic root aneurysms that can lead to acute left heart failure. The etiology of aortic root aneurysms is not yet completely clear and is mainly related to genetic diseases, such as Marfan syndrome and atherosclerosis. It can also occur secondary to aortic valve stenosis or a bivalve deformity. Surgery is the primary treatment for aortic root aneurysms, and aortic root replacement is a classic surgical method. However, the incidences of perioperative complications and mortality are relatively high, particularly in high-risk patients. In recent years, the anatomical structure of the aortic root has been gradually refined, and an in-depth understanding of root aneurysms has led to individualized treatment methods. Conservative drug therapy (ß-receptor blockers, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers), Bentall and modified Bentall surgeries (Button technology, Cabrol surgery, and modified Cabrol surgery), valve-sparing aortic root replacement (David and Yacoub), personalized external aortic root support, and endovascular intervention therapy have significantly improved the perioperative and long-term survival rates of patients with aortic root aneurysms. However, different treatment methods have their own advantages and disadvantages. This review aimed to summarize the current research progress and treatment of aortic root aneurysms.

[PMID: 37640626 DOI: 10.1016/j.acvd.2023.07.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 07/25/2023] [Accepted: 07/31/2023] [Indexed: 08/31/2023]
Abstract
BACKGROUND Although, valve sparing is commonly performed in patients with Marfan syndrome, feasibility and results of cusp repair for aortic insufficiency have not been studied. AIM To report on the outcomes and durability of aortic cusp repair in valve sparing in patients with Marfan syndrome. METHODS All consecutive adult patients with Marfan syndrome who underwent remodelling and annuloplasty with aortic valve repair for aortic insufficiency between May 2005 and December 2020 were included. Patients with Marfan syndrome treated for aortic aneurysm, but without aortic insufficiency, were excluded. Data were collected prospectively and reviewed retrospectively from the Aorticvalve repair International Registry (AVIATOR). RESULTS During the study period, 71 patients with Marfan syndrome were referred to surgery. Fifty-five patients with connective tissue disease and aortic insufficiency with aorta aneurysm were treated: 46 underwent aortic valve repair and nine underwent aortic valve replacement (five mechanical aortic valve replacements and four biological aortic valve replacements). The mean age was 42.9±15.4 years, and the mean EuroScore II was 2.5±2.2. No patient died, and no patient had significant aortic insufficiency (grade≥II) at discharge. The 5-year survival rate estimate was 94.4%, which seems statistically similar to that of the age- and sex-matched general population. At 5 years, freedom from reoperation was 94.6%, and the incidence of infective endocarditis was 2.6%. No valve thrombosis, aortic dissection, major bleeding events, thromboembolic events (stroke) or myocardial infarctions were noted during follow-up. CONCLUSION Remodelling and aortic valve repair showed excellent durability at 5 years, even in connective tissue disorders.

Abstract
The clinical outcome of severe aortic regurgitation (AR) remains suboptimal, but surgery has been shown to have survival benefit over medical therapy. Postoperative survival is inferior in patients with reduced left ventricular function, and therefore early surgical intervention is recommended. Aortic valvuloplasty (AVP) is an attractive option to avoid the major drawbacks of prosthetic valves but has not been widely adopted. The etiology of AR is classified functionally into three groups: normal leaflet motion (type I), cusp prolapse (type II), and restriction (type III). Type I with dilatation of the sinus of Valsalva (type Ib) can be repaired by aortic valve reimplantation or aortic root remodeling with similar valve stability. Type I with dilatation of the aortic annulus (type Ic) can be managed by annuloplasty. Type II can be corrected by plication or resuspension techniques. Pericardial patch is necessary in AVP for type Id (perforation/fenestration) and type III but is associated with risk of recurrence. Bicuspid aortic valve is classified according to commissure angle: symmetrical, asymmetrical, and very asymmetrical. Tricuspidization is recommended for repair of very asymmetrical valves to avoid postoperative stenosis. Recent progress has achieved similar reoperation rates between bicuspid and tricuspid aortic valve repair. For Marfan syndrome, valve-sparing root replacement is advantageous compared to Bentall operation regarding late survival, thromboembolic and hemorrhagic events, and endocarditis. Similar findings have been reported in acute aortic dissection. Both remodeling and reimplantation procedures provide similar favorable outcomes in these settings. Recent advances in AVP are summarized by quantitative assessment of cusp configuration (effective height and geometric height), graft size decision, use of template to cut the graft, and videoscopic assessment of post-repair cusp configuration. Due to these advances, AVP shows superior results to replacement surgery. Further concrete evidence with larger case volumes and longer observation periods are necessary to popularize AVP.

Abstract
INTRODUCTION Conventional aortic root and valve-sparing root replacement surgery are two current surgical treatments for aortic dilatation syndromes. This review article aims to review the current literature surrounding these two established techniques. AREAS COVERED This review article will address the current indications for valve-sparing root replacement surgery, technical considerations in surgical planning and a comparison of clinical outcomes between these two surgical techniques. EXPERT OPINION Valve-sparing root replacement surgery is a safe and established treatment for aortic syndromes. Valve-sparing surgery procedure avoids the inherent risk of prosthetic valve dysfunction and prosthesis infection by preserving the native aortic valve compared to conventional aortic root surgery. This has been demonstrated in various observational studies and should be considered in clinically and anatomically appropriate patients. Other technical considerations, such as reimplantation versus remodeling technique and aortic cusp repair in select patients, may impact in short-term procedural and long-term clinical success with valve-sparing surgery.

Fifteen-Year Outcomes After Valve-sparing Aortic Root Remodelling or Exclusion of the Non-Coronary Sinus: When to Preserve the Sinuses of Valsalva? Heart Lung Circ 2022; 31:1291-1299. [PMID: 35662487 DOI: 10.1016/j.hlc.2022.04.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 03/24/2022] [Accepted: 04/02/2022] [Indexed: 11/21/2022]
Abstract
BACKGROUND Isolated exclusion of the non-coronary sinus (NCS) is an attractive strategy in valve-sparing aortic root surgery, which avoids the mobilisation and re-implantation of coronary ostia. However, the long-term durability of aortic valve repair and the fate of remnant sinuses of Valsalva remain unclear. METHOD From January 2006 to December 2013, 29 patients underwent replacement of the ascending aorta extending to the NCS (group NCS) and 56 patients underwent a modified Yacoub procedure (group MY) in our centre by a single surgeon. Significant difference of preoperative parameters was observed between two groups in the presence of bicuspid aortic valve (41.4% vs 12.5%, p=0.002) and the diameter of the sinus of Valsalva (47.3±4.7 mm vs 51.5±4.9 mm, p=0.01). RESULTS The group NCS, as compared to the group MY, was associated with significantly shorter cardiopulmonary bypass time (106.6±40.5 min vs 138.4±37.5 min, p=0.001) and aortic cross clamping time (69.0±21.8 min vs 105.4±27.8 min, p<0.01). The mean follow-up was 11.5±2.8 years. No surgical re-intervention was performed for aortopathies of the aortic root; the neo-sinus were not dilated in either groups (38.2±4.2 mm vs 34.0±4.0 mm, p<0.01). The 10-year freedom from aortic valve-related re-operation was estimated to be 96.6±3.4% and 94.5±3.1% (p=0.58), and the cumulative 10-year survival rates were 95.2±4.6% and 85.6±4.7% (p=0.61) in the group NCS and the group MY, respectively. CONCLUSIONS Aortic valve-sparing isolated NCS replacement can be safely performed in selected patients; its early outcomes, overall survival and long-term freedom from aortic valve-related or aortopathy-related re-intervention were comparable to those obtained with the Yacoub procedure.

Abstract
PURPOSE OF REVIEW The purpose of this article is to review the contemporary evidence supporting valve-sparing aortic root replacement as the best option for patients with aortic root aneurysms and preservable aortic valves as well as to review the technical variations and modern adjuncts of these operations that impact both short and long-term durability. RECENT FINDINGS In patients with an aortic root aneurysm, with or without aortic valve regurgitation, valve-sparing aortic root replacement provide excellent clinical outcomes and stable valve function over several decades. Successful execution of this operation depends on careful patient selection and a thorough understanding of the anatomical and physiological relationships between the various components of the aortic root. Echocardiography remains the mainstay of imaging to determine the feasibility of valve-sparing root replacement. SUMMARY Valve-sparing aortic root replacement is an excellent alternative to composite valve graft replacement in nonelderly patients with aortic root aneurysms. Dedicated aortic root surgeons perform several technical variations of valve-sparing procedures aimed at matching the specific aortic root disorder with the optimal operation.
