Background: Preprocedural computed tomography (CT) workup with assessment of virtual transcatheter heart valve-to-coronary ostia (VTC) distance and transcatheter heart valve-to-sinus (VTS) distances is recommended to assess the risk of coronary obstruction following valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR).
Objectives: The authors sought to investigate the agreement of predicted VTC and VTS distances and observed post-TAVR anatomy on CT and their relationship with transcatheter heart valve (THV) expansion and deployment conditions.
Methods: Fifty-one patients who underwent a balloon-expandable ViV procedure were included in this study.
Article Synopsis
- The cusp-overlap (CO) technique is a new method for placing heart valves in patients and is becoming more popular.
- This study looked at how well this method works, how deep the valves are placed, and the results after one month for older patients receiving a specific heart valve called SAPIEN 3.
- The CO technique was found to be safe and helps to place the heart valve better, but more research is needed to see if it can lower complications like needing a pacemaker.
Background: Transcatheter heart valve (THV) dysfunction with an elevated gradient or paravalvular leak (PVL) may be documented late after THV implantation. Medical management, paravalvular plugs, redo THV replacement, or surgical valve replacement may be considered. However, late balloon dilatation is rarely utilized because of concerns about safety or lack of efficacy.

Objective: To conduct a patient-level economic analysis of the RAPID-TnT randomised trial in patients presenting with suspected acute coronary syndrome (ACS).
Methods: An economic evaluation was conducted with 3265 patients randomised to either the 0/1-hour hs-cTnT protocol (n = 1634) or the conventional 0/3-hour standard-of-care protocol (n = 1631) with costs reported in Australian dollars.
Article Synopsis
- Surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) are both treatments for aortic stenosis, and this study aimed to compare TAVR performed on failed transcatheter valves (TAV-in-TAV) versus surgical valves (TAV-in-SAV).
- Data from 434 TAV-in-TAV and 624 TAV-in-SAV procedures were analyzed after matching 330 patients from both groups, focusing on procedural success, safety, and 30-day and 1-year mortality rates.
- Results showed that TAV-in-TAV had higher procedural success rates (72.7% vs. 62.4%) and better aortic valve area and
Objective: Many meta-analyses have provided synthesised likelihood ratio data to aid clinical decision-making. However, much less has been published on how to safely combine clinical information in practice. We aimed to explore the benefits and risks of pooling clinical information during the ED assessment of suspected acute coronary syndrome.

Despite significant advances, it remains unclear which modality results in better outcomes. This meta-analysis of randomized controlled trials (RCT) and observational studies was undertaken to compare the techniques in terms of effectiveness and safety.
