Acute Occlusion of Right Coronary Artery During Transcatheter Aortic Valve Replacement of a Bicuspid Valve Open
When transcatheter aortic valve replacement is performed in the setting of a bicuspid aortic valve, coronary artery-related complications may be at increased risk for failed percutaneous bailout procedures. When assessing the risk of coron…

Outcomes after transcatheter mitral valve implantation in valve‐in‐valve, valve‐in‐ring, and valve‐in‐mitral annular calcification Open
Aims We aimed to evaluate transcatheter mitral valve implantation (TMVI) using predominantly balloon‐expandable transcatheter heart valves (THV) in patients with a landing zone for a percutaneously delivered prosthesis. Background Patients…

Procedural and clinical outcomes of patients undergoing a TAVI in TAVI procedure: Rationale and design of the multicentre, prospective, observational ReTAVI registry Open
Background Transcatheter aortic valve implantation (TAVI) is increasingly being used in younger patients and those with lower peri‐procedural risk, meaning more patients will live long enough to experience structural valve deterioration (S…

Endovascular repair in patients with aortic dissection and aortic aneurysm: A retrospective cohort study. Open
Background Therapeutic options in patients with aortic diseases include medical treatment, surgical and percutaneous intervention. The latter has been proved to be safe in patients with aortic aneurysm (AA) and aortic dissection (AD), but …

Implantation depth of balloon‐expandable transcatheter heart valves and risks for permanent pacemaker implantation and midterm adverse events Open
Background Permanent pacemaker implantation (PPI) remains a relevant complication after transcatheter aortic valve implantation (TAVI) and its impact on outcome remains controversial. Aims This study aimed to analyze the effects of implant…

Coronary artery restenosis treatment with plain balloon, drug-coated balloon, or drug-eluting stent: 10-year outcomes of the ISAR-DESIRE 3 trial Open
Aims The best interventional strategy for the treatment of drug-eluting stent (DES) in-stent restenosis (ISR) is still unclear and no data from randomized trials beyond 3-year follow-up are available. We aimed to define 10-year comparative…

Iliofemoral artery predilation prior to transfemoral transcatheter aortic valve implantation in patients with aortic valve stenosis and advanced peripheral artery disease Open
Objectives To investigate the feasibility and safety of percutaneous transluminal angioplasty (PTA) of the iliofemoral arteries (IFA) before transfemoral transcatheter aortic valve implantation (Tf‐TAVI) in patients with advanced periphera…

ACURATE neo2 versus SAPIEN 3 Ultra for transcatheter aortic valve implantation Open
Short-term outcomes after TAVI using the Neo2 or Ultra THV were excellent and, overall, comparable. However, transvalvular gradients were lower with the Neo2, which translated into higher rates of device success. Rates of mild PVL were sig…
