Feasibility of transcaval access TAVI in morbidly obese patients: A single-center experience.

Objectives: We report a single-center experience in utilizing the transcaval-access transcatheter aortic valve implantation (TAVI) as an alternative approach in morbidly obese patients.

Background: Morbidly obese patients present frequently for TAVI. Transfemoral arterial access TAVI in these patients is technically challenging due to deep arterial access, resulting in a higher risk of vascular complications.

The impact of learning-curve-experience on transcatheter aortic valve replacement outcomes: Insights from the United Kingdom and Ireland all-comers second-generation ACURATE neo™ transcatheter aortic heart valve registry.

Background: The ACURATE neo™ is a novel, second-generation self-expanding supra-annular transcatheter heart valve (THV). The objective of this multi-centre registry is to assess the safety, clinical utility, and impact of 'learning-curve-experience' (LCE) on transcatheter aortic valve replacement outcomes in the United Kingdom (UK) and Ireland.

Methods: We prospectively collected data from seven ACURATE neo™ THV implanting centres (n = 484) between February 2016 and November 2020.

Procedural Mortality With Transcatheter Aortic Valve Replacement - Balloon Inflation is Associated With Increased Risk.

Objectives: To assess the impact of balloon use for predilation, valve implantation, or postdilation on in-hospital mortality among patients undergoing transcatheter aortic valve replacement (TAVR).

Background: TAVR utilizes self-expanding, mechanically expanding, or balloon-expandable valves. Balloon inflation is inherent to deployment of balloon-expandable valves.

Valve-in-Valve Transcatheter Aortic Valve Implantation for the Failing Surgical Perceval Bioprosthesis.

Introduction: The Perceval Valve has been increasingly used in Surgical Aortic Valve Replacement (SAVR) recently due to ease of implantation. However, we have seen some cases of relatively early haemodynamic failure of the Perceval valve and these patients may then present for valve-in-valve transcatheter aortic valve implantation (ViV-TAVI). Experience of ViV-TAVI in the Perceval valve is limited.

Elective versus urgent in-hospital transcatheter aortic valve implantation.

Background: Transcatheter aortic valve implantation (TAVI) is maturing as a treatment option and is now often undertaken during an unscheduled index hospital admission. The aim of this study was to look at procedural and mid-term outcomes of patients undergoing elective versus urgent in-hospital transcatheter aortic valve implantation.

Methods: We identified a total of 1,157 patients who underwent TAVI between November 2007 and November 2019 at the Sussex Cardiac Centre in the UK.

Amplatzer device closure of femoral pseudoaneurysm after transcatheter aortic valve implantation: An alternative to surgical repair.

Iatrogenic femoral artery pseudoaneurysm is an infrequent but troublesome complication of vascular access during transcatheter aortic valve implantation. There are non-invasive, percutaneous and surgical treatment options for management of this complication. This case series report demonstrates a novel technique using an Amplatzer Duct Occluder II closure device to successfully treat iatrogenic common femoral pseudoaneurysm following transcatheter aortic valve implantation.
