This study sought to compare the morbidity and mortality of redo aortic valve replacement (redo-AVR) versus valve-in-valve trans-catheter aortic valve implantation (valve-in-valve TAVI) for patients with a failing bioprosthetic valve. A multicentre UK retrospective study of redo-AVR or valve-in-valve TAVI for patients referred for redo aortic valve intervention due to a degenerated aortic bioprosthesis. Propensity score matching was performed for confounding factors. From July 2005 to April 2021, 911 patients underwent redo-AVR and 411 patients valve-in-valve TAVI. There were 125 pairs for analysis after propensity score matching. Mean age was 75.2±8.5 years. In-hospital mortality was 7.2% (n=9) for redo-AVR vs 0 for valve-in-valve TAVI, p=0.002. Surgical patients suffered more post-operative complications, including IABP support (p=0.02), early re-operation (p<0.001), arrhythmias (p<0.001), respiratory and neurological complications (p=0.02 and p=0.03) and multi-organ failure (p=0.01). The valve-in-valve TAVI group had a shorter intensive care unit and hospital stay (p <0.001 for both). However, moderate aortic regurgitation at discharge and higher post-procedural gradients were more common after valve-in-valve TAVI (p<0.001 for both). Survival probabilities in patients who were successfully discharged from hospital were similar after valve-in-valve TAVI and redo-AVR over the 6-year follow-up (log-rank p=0.26). In elderly patients with a degenerated aortic bioprosthesis, valve-in-valve trans-catheter aortic valve implantation provides better early outcomes, as opposed to redo surgical aortic valve replacement, although there was no difference in mid-term survival in patients successfully discharged from hospital.
Few cases of true superior gluteal artery (SGA) aneurysms have been described in the English-language literature. This is the twenty-second reported case. SGA aneurysms can pose diagnostic problems, specifically when they are non-pulsatile and also therapeutic challenges when they are large. Although more aneurysms are being subjected to endovascular therapies, SGA aneurysmectomy or aneurysmorrhaphy still remain valid therapeutic options, especially in resource-poor settings. Surgery provides quick symptom resolution and still is the only means by which tissue for definitive histological diagnosis can be obtained.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
