INTRODUCTION AND OBJECTIVES: The SAPIEN 3 (S3) valve and the Medtronic Evolut R (EVR) are second-generation transcatheter valves, designed to further reduce the rate of paravalvular aortic regurgitation (AoR). The aim of this study was to compare the 2 devices in terms of valve performance in a case-matched study with independent echocardiographic analysis. METHODS: Of a population of 201 patients who underwent transcatheter aortic valve implantation, 144 patients (S3, n = 80; EVR, n = 64) were matched according to aortic annulus diameter and aortic valve calcium score, as assessed by computed tomography...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) using a self-expanding valve has been shown to be superior to an open operation in high-risk patients. Extensive iliofemoral peripheral vascular disease can prohibit femoral access. In these cases, direct aortic (DA) implantation may be a suitable option. METHODS: The current analysis compared outcomes in patients undergoing TAVR with the self-expanding CoreValve prosthesis (Medtronic, Minneapolis, MN) by direct aortic (DA) access vs iliofemoral (IF) access...

The relationship between adherence to the recommended CoreValve sizing parameters and clinical outcomes is not well known for the recently released 34 mm valve, which is currently the largest available transcatheter valve. There is a presumed temporal reduction in paravalvular regurgitation in patients who receive an in-range valve, however, certain patients possess annular dimensions that are too large. We therefore describe two patients with annular dimensions larger than the manufacturer recommended range for the 34 mm CoreValve, who despite this underwent transcatheter aortic valve replacement with excellent clinical outcomes...

The aim of this study was to investigate the incidence, predictors and outcome of prosthesis-patient mismatch (PPM) following transcatheter aortic valve replacement (TAVR). A total of 30 articles incorporating 4,691 patients were identified. The pooled incidences of overall, moderate and severe PPM following TAVR were 33.0%, 25.0% and 11.0% respectively. Medtronic CoreValve (MCV) had lower incidence of overall (32% vs: 40%, P < 0.0001) and moderate (23% vs 32%, P < 0.0001) than Edwards Sapien (ESV)...

BACKGROUND: While transcatheter aortic valve implantation (TAVI) has traditionally been supported intraprocedurally by transoesophageal echocardiography (TOE), transthoracic echocardiography (TTE) is increasingly being used. We evaluated echocardiographic imaging characteristics and clinical outcomes in patients who underwent TTE during TAVI (TTE-TAVI). METHODS AND RESULTS: A select team of dedicated sonographers and interventional echocardiographers performed TTE-TAVI in 278 patients, all of whom underwent TAVI through transfemoral access...

BACKGROUND: Iliofemoral arterial disease can preclude transfemoral (TF) transcatheter aortic valve replacement (TF-TAVR). Transthoracic access by direct aortic or a transapical approach imparts a greater risk of complications and death than TF access. We hypothesized that subclavian/axillary arterial (SCA) access offers equivalent risks and outcomes as TF access. METHODS: The outcomes of 202 patients from the CoreValve (Medtronic, Minneapolis, MN) United States Pivotal Trial Program treated with SCA access were propensity matched with patients treated with TF access and analyzed...

Transcatheter aortic valve replacement (TAVR) has become standard therapy for patients with severe aortic stenosis who are deemed at least intermediate risk for surgical valve replacement. Over the past decade, several technological advances have taken place to improve the quality and safety of these devices. The current commercially available valves are broadly grouped into balloon expandable and self-expandable valves. The latest iteration of the self-expandable valve is Medtronic's repositionable valve known as the Evolut PRO system...

We present a case of successful bicaval Melody valve implantation to treat severe mitral regurgitation in a 44-year-old man with d-transposition of the great arteries, repaired via a Mustard operation. The patient sustained injury to the anterior mitral valve leaflet during laser extraction of a ventricular pacing lead resulting in acute, severe, symptomatic mitral regurgitation. The presence of systemic venous baffles of similar caliber to right ventricular outflow tract conduits allowed for implantation of Melody valves within each baffle...

Transcatheter aortic valve implantation (TAVI) has emerged as a viable treatment modality for patients with severe aortic valve stenosis and multiple co-morbidities. More recent indications include the use of transcatheter heart valves (THV) to treat degenerated bioprosthetic surgical heart valves (SHV), which are failing due to stenosis or regurgitation. Valve-in-valve (VIV) procedures in the aortic position have been performed with a variety of THV devices, although the balloon-expandable SAPIEN valve platform (Edwards Lifesciences Ltd, Irvine, CA, USA) and self-expandable CoreValve platform (Medtronic Inc...

The hemodynamic performance of artificial aortic valves (AVs) and the probability for structural valve deterioration can be linked to the valve kinematics. Comparability among different studies is limited because of variations in the experimental setups and physiologic boundary conditions. This study presents results of kinematic measurements of bioprosthetic and mechanical AVs that were tested in an identical experimental setting such that they can be directly compared with each other. The kinematics of AVs is typically presented in the form of the geometric orifice area and its temporal evolution...

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...

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...
