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

open access: yesCatheterization 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.

Natural Progression of Low-Gradient Severe Aortic Stenosis With Preserved Ejection Fraction [PDF]

open access: yes, 2014
Because the natural progression of low-gradient aortic stenosis (LGAS) has not been well defined, we performed a retrospective study of 116 consecutive patients with aortic stenosis who had undergone follow-up echocardiography at a median interval of 698

Clinical Impact of Adherence to Fractional Flow Reserve Guidance in Acute Coronary Syndrome

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Fractional flow reserve (FFR) is established to guide revascularization in stable coronary disease and non‐culprit lesions in acute coronary syndromes (ACS). However, real‐world adherence to FFR guidance across the spectrum of ACS presentations, including ambiguous culprit scenarios, remains incompletely characterized.

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

open access: yesCatheterization 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.

Investigations on non-invasive hemodynamics after transcatheter aortic valve replacement considering low-gradient aortic valve stenosis

open access: yes, 2023
Ziel dieser Arbeit war es die kurzfristigen Veränderungen der Hämodynamik nach Implantation eines transfemoralen Aortenklappenersatzes, mit besonderem Fokus auf die Unterschiede zwischen Low Gradient Aortenstenose und Non Low Gradient Aortenstenose ...

Spatial Mismatch Between Angiographic Obstruction and Plaque Destabilization in Acute Coronary Syndromes: A Conceptual Narrative Review

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The identification of the “culprit lesion” in acute coronary syndromes (ACS) traditionally relies on coronary angiography, assuming that the most severe stenosis, abrupt occlusion, or largest filling defect marks the site of plaque destabilization.

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

open access: yesCatheterization 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.

Invasive Hemodynamic Characteristics of Low Gradient Severe Aortic Stenosis Despite Preserved Ejection Fraction [PDF]

open access: yes, 2013
ObjectivesThe study sought to compare echocardiographic with invasive hemodynamic data in patients with “paradoxic” aortic stenosis and in patients with conventionally defined severe aortic stenosis.BackgroundControversy exists whether low gradient ...

Diagnostic Agreement and Threshold Correspondence Between Resting Full‐Cycle Ratio and Nicorandil‐Based Fractional Flow Reserve in Intermediate Coronary Stenosis: A Prospective Single‐Center Registry

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background RFR has shown good aggregate agreement with FFR, including in prior Asian cohorts using intracoronary nicorandil. Where RFR‐FFR disagreement is concentrated relative to the FFR 0.80 decision boundary, and how the two binary thresholds correspond, remain incompletely characterized. Methods In a prospective single‐center registry, 300
