Published: June 2023

Aortic stenosis in patients with previous valve-sparing root replacement represents a challenge, given the substantial morbidity and mortality rates in case of reoperation. Here, we present the case of a patient with late severe aortic stenosis 12 years after valve-sparing aortic root replacement. He was successfully treated by transapical aortic valve implantation. External ring annuloplasty, by reducing the native annuloaortic ectasia, allows transcatheter aortic valve replacement in case of stenotic deterioration of the native valve after valve-sparing aortic root replacement.

Aortic regurgitation is a common valve disease and can be caused by delineated findings such as fenestrations or hardly discernible alterations of the aortic root geometry. Therefore, aortic regurgitation can be a challenging diagnosis during an autopsy. Cardiac surgeons, however, are confronted with comparable problems during surgery and have developed a refined knowledge of the anatomy of the aortic root including its geometry.

Background: Calcific aortic valve disease is the pathological remodeling of valve leaflets. The initial steps in valve leaflet osteogenic reprogramming are not fully understood. As TERT (telomerase reverse transcriptase) overexpression primes mesenchymal stem cells to differentiate into osteoblasts, we investigated whether TERT contributes to the osteogenic reprogramming of valve interstitial cells.

Background Patients undergoing transcatheter aortic valve implantation (TAVI) are often elderly, and perioperative and long-term risk assessments should primarily consider cognitive function, comorbidities, and procedural complexity. This study investigated the association between cognitive function and mortality in patients with severe aortic valve stenosis (AS) who underwent TAVI. Methodology This single-center, retrospective cohort study consecutively registered patients who underwent TAVI between December 2014 and December 2018.
