Comparison Between the Acurate Neo and the Acurate Neo 2 Transcatheter Heart Valve System: Impact of Midframe Under‐Expansion

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) with the Acurate Neo has been linked to a significant incidence of paravalvular leakage (PVL), addressed by the Acurate Neo 2 incorporating an active sealing skirt. Recent findings suggest that midframe under‐expansion is associated with worse outcomes.

Echocardiography Aided by Computed Tomography to Diagnose Obstructive Masses in Patients with Prosthetic Heart Valves

, 2020
To the Editor: We appreciate Kealhofer and colleagues’ report on their beneficial use of cardiac computed tomography (CT) for evaluating prosthetic aortic valve dysfunction.1 We want to contribute further by drawing attention to the role of cardiac CT in

Gutter Rotation Technique for Percutaneous Ipsilateral Retrieval of a Ruptured SAPIEN‐3 Balloon

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Balloon rupture during transcatheter aortic valve replacement (TAVR) with balloon‐expandable valves is a rare but potentially serious complication that may result in incomplete valve expansion, difficult device retrieval, and vascular injury.

Mechanisms and Management of Acquired Aseptic Intracardiac Communications After Transcatheter Aortic Valve Implantation: Single‐Center Case Series Insights

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Acquired aseptic intracardiac communications (AICCs) are rare but clinically relevant structural complications following transcatheter aortic valve implantation (TAVI), typically resulting from mechanical injury to the aortic annulus, interventricular septum, or adjacent structures.

Early Experience With Evoque Transcatheter Tricuspid Valve Replacement in Carcinoid Heart Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Tricuspid regurgitation (TR) is nearly universal in carcinoid heart disease (CHD), but surgical replacement carries significant risk, and CHD was excluded from the landmark TRISCEND II trial. We present seven patients with CHD undergoing Evoque transcatheter tricuspid valve replacement (TTVR) at two tertiary centers.

Transthoracic three-dimensional echocardiography for the assessment of straddling tricuspid or mitral valves [PDF]

, 2000
Background The advent of 3D echocardiography has provided a technique which, potentially, could afford significant additional information over conventional cross-sectional echocardiography in the assessment of patients with straddling atrioventricular ...
