BACKGROUND AND OBJECTIVE: With aging, the progression of atherosclerosis in the coronary arteries is expected. The Medtronic™ self-expandable aortic bioprosthetic valve is deployed in the supra-annular position, and it has been challenging to selectively engage coronary arteries post-transcatheter aortic valve replacement (TAVR) even though there are diamond-shaped spaces in the mesh frame within the valve. Given the scarcity of data, we analyzed angiographic and clinical data from all patients requiring coronary angiography (CA) or intervention post-TAVR...

Background: We assessed whether a near-infrared spectroscopy (NIRS)-based algorithm for the personalized optimization of cerebral oxygenation during cardiopulmonary bypass combined with a restrictive red cell transfusion threshold would reduce perioperative injury to the brain, heart, and kidneys. Methods: In a randomized controlled trial, participants in three UK centres were randomized with concealed allocation to a NIRS (INVOS 5100; Medtronic Inc., Minneapolis, MN, USA)-based 'patient-specific' algorithm that included a restrictive red cell transfusion threshold (haematocrit 18%) or to a 'generic' non-NIRS-based algorithm (standard care)...

Transcatheter aortic valve replacement (TAVR) has become the standard of care for the treatment of severe aortic stenosis in individuals who are at prohibitive surgical risk and presents a viable alternative to surgery in selected patients who are at high operative risk. To date, outcomes from the PARTNER (Placement of AoRtic TraNscathetER Valve) and Medtronic CoreValve® US Pivotal trials continue to show the benefits of TAVR in these high-risk subgroups out to 5 and 3 years, respectively (as reported by Mack et al...

Background  Transcatheter heart valve (THV) therapies have shown to be an alternative to surgical valve replacement, especially in high-risk patients requiring redo surgery. However, reports of transcatheter-based interventions in tricuspid valve position are scarce. Case Description  Here, we report a case of successful concomitant transcatheter aortic valve-in-valve (ViV) and tricuspid valve-in-ring (ViR) procedures using a 23-mm CoreValve Evolut R THV (Medtronic, Inc., Minneapolis, Minnesota, United States) in aortic position and a 29-mm SAPIEN3 (Edwards Lifesciences, Inc...

The goal is to inform in depth on transcatheter aortic valve replacement (TAVR) prosthesis mechanical behavior, depending on frame type, design, and size, and how it crucially impacts the oversizing issue in clinical use, and ultimately the procedure outcome. Transcatheter aortic valve replacement is an established therapy for high-risk patients suffering from aortic stenosis, and the indication for TAVR is progressively expanding to intermediate-risk patients. Choosing the optimal oversizing degree is crucial to safely anchor the TAVR valve-which involves limiting the risks for embolism, aortic regurgitation, conductance disturbance, or annulus rupture-and to increase the valve prosthesis performance...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with severe aortic stenosis and high surgical risk. Currently, various prosthesis types are available. Atrioventricular block (AVB) requiring pacemaker (PM) implantation is a typical complication after TAVI. This study investigated the recovery of AV node conduction and mid-term outcome of patients with or without PM implantation after TAVI according to prosthesis type. METHODS: From July 2008 to May 2015, 856 transcatheter heart valves were implanted at our center (age: 80...

BACKGROUND: Surgical aortic valve replacement (SAVR) is the treatment of choice in severe symptomatic aortic valve disease. New techniques and prostheses have been recently developed to facilitate the procedure and reduce aortic cross-clamp time (AOx). The aim of this study was to analyse the different procedural steps in order to identify the most time-consuming part during aortic clamping time and to compare impact of experience on procedural aspects. METHODS: AOx during SAVR was divided into five consecutive steps...

Aims: Leadless cardiac pacing has recently been proposed as alternative to conventional right ventricular (RV) pacing. With this approach, devices are directly screwed or fixed with tines in the RV wall, but the possible consequences on RV and tricuspid valve (TV) structure and function remain unknown. We thus conducted a study to evaluate this potential impact in chronically implanted patients. Methods and results: Repeated echocardiographic studies were performed prior to implantation, at discharge, and 2 months thereafter on all consecutive patients implanted with a leadless pacemaker at our centre between October 2014 and end-December 2015...

BACKGROUND: Nowadays the prognostic role of gender as a relevant factor after transcatheter aortic valve implantation (TAVI) is still unfair, since available data in the literature are few and uneven. The aim of this survey was to collect acute and 30-day safety and efficacy clinical data in high- and intermediate-risk women, who underwent TAVI with new-generation devices, in the Campania Region. METHODS: All medium and high-volume TAVI centers in Campania have been invited to fulfill an online, ad-hoc questionnaire, collecting pre-, peri- and post-procedural data concerning female patients, treated between January and December 2016...

With new surgical techniques, more and more complex congenital heart defects are treated requiring sometimes right ventricle to pulmonary artery conduit implantation. In order to extend RV to PA conduit lifespan, 15 years ago a valved stent was developed. The implantation technique was progressively standardized to decrease risks of procedural complications. Medium and long-term hemodynamic results of the stent were so good that indications were broadened to native or complex right ventricular outflow tracts...

Transcaval aortic access has been used for deployment of transcatheter aortic valves in patients in whom conventional arterial approaches are not feasible. This access can be vital in other situation when large bore access is needed. We described a case of 65-year-old man who had large thoracic descending aortic aneurysm with diffuse bilateral iliac disease precluding the arterial access required for the procedure. The patient underwent successful transcaval access with placement of 22-Fr balloon expandable sheath followed with successful deployments of 32 mm × 32 mm × 150 mm Valiant stent graft (Medtronic, Minneapolis, MN)...
