Background: We analyzed our early and midterm results with aortic valve reimplantation surgery to determine the influence of Marfan syndrome and bicuspid valves on outcomes with this technique.
Methods: Between March 2004 and December 2015, 267 patients underwent aortic valve reimplantation operations. The mean diameter of the sinuses of Valsalva was 50 ± 3 mm and moderate/severe aortic regurgitation was present in 34.4% of these patients. A bicuspid aortic valve was present in 21% and 40% had Marfan syndrome.
Results: Overall 30-day mortality was 0.37% (1/267). Mean follow-up was 59.7 ± 38.7 months. Overall survival at 1, 3, and 5 years was 98 ± 8%, 98 ± 1%, and 94 ± 2%, respectively. Freedom from reoperation and aortic regurgitation >II was 99 ± 5%, 98 ± 8%, 96.7 ± 8%, and 99 ± 6%, 98 ± 1%, 98 ± 1%, respectively at 1, 3, and 5 years follow-up, with no differences between Marfan and bicuspid aortic valve groups. (p = 0.94 and p = 0.96, respectively). No endocarditis or thromboembolic complications were documented, and 93.6% of the patients did not receive any anticoagulation therapy.
Conclusions: The reimplantation technique for aortic root aneurysms is associated with excellent clinical and functional outcomes at short and mid-term follow-up.

Background: Evidence regarding the incidence of prosthesis-patient mismatch (PPM) and long-term mortality after transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS) is scarce.
Objectives: This study sought to assess the incidence and prognostic impact of PPM after TAVR for bicuspid AS compared with that for tricuspid AS.
Methods: In total, 7,393 patients who underwent TAVR were prospectively enrolled in the OCEAN-TAVI (Optimized Catheter Valvular Intervention Transcatheter Aortic Valve Implantation) registry, an ongoing Japanese, multicenter registry.
Revisiting the Neuropsychological and Clinical Profile of Mosaic Turner Syndrome With a Ring X Chromosome.

Determining karyotype-phenotype correlations for individuals with Turner syndrome ("TS individuals") is a longstanding research endeavor. The limited literature on Turner syndrome (TS) with a ring X chromosome hinders counseling about the neuropsychological and clinical features. To further characterize these phenotypes, we compared 27 TS individuals with 46,X,r(X)/45,X ("ring X") to 50 non-mosaic 45,X, and 27 mosaic 45,X/46,XX ("mosaic 45,X") individuals.

Background: The human microbiome is crucial in regulating intestinal and systemic functions. While its role in cardiovascular disease is better understood, the link between intestinal microbiota and valvular heart diseases (VHD) remains largely unexplored.
Methods: Peer-reviewed studies on human, animal or cell models analysing gut microbiota profiles published up to April 2024 were included.

Severe mitral regurgitation (MR) following surgical repair of the mitral valve poses a significant clinical challenge. Patients who have undergone surgery are typically at high risk for a second operation. This report details the case of a 54-year-old male who underwent aortic valve replacement and mitral valve repair using a 34-ring, 14 years prior.
