The Influence of the Learning Curve on Clinical Outcomes in Balloon-Expandable versus Self-Expandable Transfemoral Transcatheter Aortic Valve Implantation.

Introduction: Balloon-expandable (BE) and self-expandable (SE) prostheses are the main types of devices currently used in transcatheter aortic valve implantation (TAVI). Despite the different designs, clinical practice guidelines do not make any specific recommendation on the selection of one device over the other. Most operators are trained in using both BE and SE prostheses, but operator experience with each of the two designs might influence patient outcomes.

Practical Approaches to Transvenous Lead Extraction Procedures-Clinical Case Series.

Transvenous lead extraction (TLE) is regarded as the first-line strategy for the management of complications associated with cardiac implantable electronic devices (CIEDs), when lead removal is mandatory. The decision to perform a lead extraction should take into consideration not only the strength of the clinical indication for the procedure but also many other factors such as risks versus benefits, extractor and team experience, and even patient preference. TLE is a procedure with a possible high risk of complications.

The effect of the learning curve on paravalvular aortic regurgitation and mid-term mortality in transfemoral transcatheter aortic valve implantation.

Objective: Paravalvular aortic regurgitation is an important independent mortality predictor in transcatheter aortic valve implantation (TAVI). Our study evaluated the association between paravalvular aortic regurgitation and mid-term mortality in relation with the learning curve, in patients with severe aortic stenosis who underwent transfemoral TAVI in the first 3 years since the establishment of the program.

Methods: Patients with severe aortic stenosis who underwent transfemoral TAVI between 2017 and 2020 were included in the analysis.

Giant ascending aortic aneurysm after aortic valve replacement.

Giant ascending aortic aneurysms are rare clinical entities and are accompanied by a high annual risk of rupture. We present the imaging, intraoperative, and pathology findings of such a case.
