We sought to evaluate the clinical and hemodynamic outcomes of the CoreValve porcine pericardial self-expanding bioprosthesis at 12-year follow-up.

Methods: 882 inoperable or high-risk patients were treated with the CoreValve bioprosthesis in 8 Italian high-volume centers between 2007 and 2011.

Use of cangrelor for complex percutaneous coronary intervention in the context of concomitant severe aortic stenosis: a case series.

Background: There is a growing need for percutaneous coronary intervention (PCI) to be performed within the same transcatheter aortic valve implantation (TAVI) procedure. In such cases, cangrelor, a fast-acting intravenous P2Y12-inhibitor with a short offset, is potential clinical utility to minimize bleeding and vascular complications during large-bore arterial access (LBAA) as well as the thrombotic risk associated with concomitant PCI.

Case Summary: We report two cases of TAVI with an indication to concomitant, high-risk PCI.

Impact of balloon post-dilation on valve durability and long-term clinical outcomes after self-expanding transcatheter aortic valve implantation.

Background: Balloon post-dilation (BPD) is a widely adopted strategy to optimize acute results of TAVI, with a positive impact on both paravalvular leak and mean gradients. On the other hand, the inflation of the balloon inside prosthetic leaflets may damage them increasing the risk of structural valve deterioration (SVD). Furthermore, the impact of BPD on long-term clinical outcomes and valve hemodynamics is yet unknown.

Impact of Pacemaker Implantation After Transcatheter Aortic Valve Replacement on Long-Term Survival in Patients With Bicuspid Aortic Valve.

Limited data are available about the impact of permanent pacemaker (PPM) implantation on long-term survival in patients with a bicuspid aortic valve (BAV) and severe aortic stenosis (AS) treated with transcatheter aortic valve replacement (TAVR). We aimed to evaluate the long-term clinical outcomes of patients with BAV with AS who underwent periprocedural PPM implantation after TAVR with a self-expandable prosthesis. Data from patients with BAV and severe AS who underwent TAVR between April 2009 and January 2022 and followed in the framework of the One Hospital ClinicalService-CoreValve Project were collected.

Outcomes of Patients With Very Severe Aortic Stenosis Treated With Transcatheter Aortic Valve Implantation.

Symptoms of aortic stenosis (AS) are not proportional to its severity and patients with very severe AS (VSAS) remain asymptomatic for a long time. The appropriate time for intervention in patients with VSAS and the effects of transcatheter aortic valve implantation (TAVI) on left ventricular hypertrophy (LVH) remain debated. Our aim was to compare the procedural and 30-day outcomes of TAVI between patients with VSAS and patients with severe AS (SAS) and the changes in LVH.

Bi-Caval Valve Implantation to Palliate Symptoms in a Case of Massive Tricuspid Regurgitation.

Mechanical Hemolysis Complicating Transcatheter Interventions for Valvular Heart Disease: JACC State-of-the-Art Review.

Mechanical intravascular hemolysis is frequently observed following procedures on heart valves and uncommonly observed in native valvular disease. In most cases, its severity is mild. Nevertheless, it can be clinically significant and even life threatening, requiring multiple blood transfusions and renal replacement therapy.

Permanent Pacemaker Implantation Following Valve-in-Valve Transcatheter Aortic Valve Replacement: VIVID Registry.

Background: Permanent pacemaker implantation (PPI) remains one of the main drawbacks of transcatheter aortic valve replacement (TAVR), but scarce data exist on PPI after valve-in-valve (ViV) TAVR, particularly with the use of newer-generation transcatheter heart valves (THVs).

Objectives: The goal of this study was to determine the incidence, factors associated with, and clinical impact of PPI in a large series of ViV-TAVR procedures.

Methods: Data were obtained from the multicenter VIVID Registry and included the main baseline and procedural characteristics, in-hospital and late (median follow-up: 13 months [interquartile range: 3 to 41 months]) outcomes analyzed according to the need of periprocedural PPI.

Percutaneous RVAD with the Protek Duo for severe right ventricular primary graft dysfunction after heart transplant.

Right ventricular primary graft dysfunction after heart transplant is a serious life-threatening condition. The severe form, refractory to maximal medical therapy, has traditionally required temporary mechanical support through veno-arterial extracorporeal membrane oxygenation or central right ventricular support. The Protek Duo is a dual lumen cannula recently introduced in the market, which allows for the institution of a percutaneous right ventricular support.
