CORONARY PERFUSION:IMPACT OF FLOW DYNAMICS AND GEOMETRIC DESIGN OF TWO DIFFERENT AORTIC PROSTHESES OF SIMILAR SIZE [PDF]

, 2012
BackgroundAortic valve replacement leads to improvement of coronary flow but not to complete normalization. Coronary hypoperfusion contributes to higher left ventricular mass persistence, arrhythmias, congestive heart failure and sudden death.

The International TrifectaTM and EpicTM Valve‐in‐Valve Registry: Insights Into Clinical & Hemodynamic Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Little is known about the clinical and hemodynamic outcome of valve‐in‐valve transcatheter aortic valve replacement (ViV‐TAVR) for failed Trifecta surgical aortic bioprotheses. Aims We aimed to compare outcomes of valve‐in‐valve transcatheter aortic valve replacement (ViV‐TAVR into failed TrifectaTM vs.

Modeling the Mitral Valve [PDF]

, 2019
This work is concerned with modeling and simulation of the mitral valve, one of the four valves in the human heart. The valve is composed of leaflets, the free edges of which are supported by a system of chordae, which themselves are anchored to the papillary muscles inside the left ventricle.

Emergent Cardiac Surgery After Transcatheter Structural Heart Procedures: Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Transcatheter structural heart procedures have become standard therapy for elderly patients with high surgical risk. Over time, these procedures have significantly increased worldwide, accompanied by a concomitant reduction of major complications, including those requiring emergent cardiac surgery (ECS).

Replacement of pulmonary artery trunk in sheep using tubular valved heterograft in non-aldehydic preservation [PDF]

, 2012
INTRODUCTION: The cardiac bioprostheses are related to thromboembolic events, infectious and degenerative diseases. Wear is mainly attributed to the denaturation of collagen. Glutaraldehyde, the predominant method of preservation of bioprostheses, favors

Impact of Elevated Preprocedural Left Ventricular Filling Pressure on Prognosis of Mild Paravalvular Regurgitation Following Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Paravalvular regurgitation (PVR) following transcatheter aortic valve replacement (TAVR) is a complication linked to poor outcomes. The prognostic impact of mild PVR, particularly in patients with elevated preprocedural left ventricular (LV) filling pressure, remains uncertain.
