Ever since the first hybrid prosthesis was used for a total aortic arch replacement, many other techniques have been developed to comply with the need for the treatment of a wide spectrum of patients and their clinical pictures. We hereby provide an overview of the most popular surgical techniques to perform a frozen elephant trunk, including our tailored approach revolving around the antegrade deployment of a Gore C-TAG endovascular stent graft sutured to a four-branched vascular prosthesis. This technique was applied to three cases of acute type A aortic dissection. Although our small series of patients consists of acute aortic dissections only, this technique could be applied to any other aortic arch pathology, such as chronic dissections or aneurysms. Moreover, we believe that, because of the individually tailored approach and widespread availability of the necessary materials, this technique can reveal itself useful in many different operative scenarios.

Background: Transcatheter aortic valve implantation (TAVI) is becoming the most important treatment strategy for aortic valve disease. With its dramatic increase, the rate of major complications and the impact of TAVI on long term outcomes is becoming a pressing issue, especially in terms of comparison with surgical aortic valve replacement (SAVR). PVE is a severe complication that can arise post-procedure, leading to significant morbidity and mortality. The aim of this meta-analysis is to compare the incidence of PVE and 30-day mortality rates between TAVI and SAVR. Methods: A comprehensive literature review was conducted, identifying studies that reported the incidence and outcomes of PVE in patients undergoing TAVI and SAVR. The selected studies were assessed for heterogeneity using the χ² test and I² statistic. A random effect model was applied to account for variability among studies. The Odds Ratios (ORs) for 30-day mortality and the incidence of PVE were calculated. Funnel plots were utilized to assess the reliability of the data and potential publication bias. Results: The analysis showed no significant difference in 30-day mortality of PVE in TAVI and SAVR, with an OR of 1.29 (CI 0.98–1.69). However, there was a significant difference in the incidence of PVE (HR 0.76, CI 0.61–0.96), with TAVI demonstrating a protective effect attributed to its lesser invasiveness and shorter procedural times. The funnel plots indicated high reliability of the data, with low standard errors and minimal publication bias. Conclusions: TAVI and SAVR carry similar 30-day mortality rates for patients with PVE; on the other hand, TAVI shows a lower incidence of PVE due to its minimally invasive nature. These findings suggest that TAVI might be a preferable option for certain patient populations, though further randomized clinical trials are needed to confirm these results and address the limitations of the current study.
