Aortic Root Replacement: A Comparison of Valve- Sparing Procedures With Mechanical Valve Replacement in Patients With Marfan Syndrome
نویسنده
چکیده
Background: Historically, surgical replacement of the aortic root in Marfan syndrome patients involved replacing the native valve with a mechanical valve resulting in the need for life-long anticoagulation. Recently, surgeons have developed procedures that spare, rather than replace the aortic valve during aortic root replacement. The goal of this systematic review is to compare valve-sparing aortic root replacement with traditional aortic root replacement with mechanical valves, and evaluate the evidence using the GRADE system. Methods: An extensive review of the literature was conducted using Medline-Ovid, PubMed, and Cinhal. Three articles that met the inclusion criteria were included in the review. Results: Similar intraoperative and early mortality rates were demonstrated between aortic root replacement with AVR and AVS. Two studies showed increased late morbidity of thromboembolic events associated with AVR compared to AVS. Follow-up times between the two groups in each study differed drastically, making it difficult to draw final conclusions regarding long-term outcomes. Conclusions: Although aortic root replacement with either AVR or AVS provides a low risk of early mortality, there are insufficient long-term data on late mortality that support recommending valve-sparing (AVS) procedures over valve-replacing (AVR) procedures at this time. After applying the GRADE system to the review, the overall quality of the evidence was determined to be low.

Objective: To evaluate the results of two operations, aortic valve-sparing and aortic root replacement, in patients with aortic root aneurysm and the Marfan syndrome. Methods: A retrospective review of 78 consecutive patients with aortic root aneurysm and the Marfan syndrome according to the Gent criteria indicated that 42 patients with normal aortic cusps had an aortic valve-sparing operation,...
متن کاملValve-sparing aortic root replacement in Marfan syndrome.
Marfan syndrome is the most common inherited connective tissue disorder, affecting approximately 1 in 10,000 live births. The cardinal features of Marfan syndrome are the abnormalities of the skeleton (tall stature, arachnodactyly, and joint hyperelasticity), eye (lens subluxation), and aorta (root aneurysm with proclivity toward rupture and dissection). Aortic catastrophe accounts for most of ...
متن کاملValve-sparing aortic root replacement in Loeys-Dietz syndrome and a novel mutation in TGFBR2
BACKGROUND Loeys-Dietz syndrome (LDS) is a recently recognized aggressive aortic disorder characterized by root aneurysm, arterial tortuosity, hypertelorism, and bifid uvula or cleft palate. The results of prophylactic root replacement using valve-sparing procedures (valve-sparing root replacement [VSRR]) in patients with LDS is not known. METHODS We reviewed all patients with clinical and ge...
متن کاملPreventative valve-sparing aortic root replacement and pregnancy outcome in Marfan syndrome.
In Marfan syndrome, with dilatation of the aortic root secondary to an underlying connective tissue defect, pregnancy can cause hemodynamic stress leading to the development of an aortic aneurysm and even a fatal aortic dissection. In the presence of existing aortic root enlargement and a family history of aortic dissection, preventative elective surgery is suggested. Aortic root replacement wi...

BACKGROUND Cardiac manifestations of Marfan syndrome include aortic root dilation and mitral valve prolapse (MVP). Only scant data exist describing MVP in patients with Marfan syndrome undergoing aortic root replacement. METHODS AND RESULTS We retrospectively analyzed data from 166 MFS patients with MVP who were enrolled in a prospective multicenter registry of patients who underwent aortic r...
