Influence of Preoperative Anatomical Characteristics on the Direction of Inflow Cannula in HeartMate 3

Artificial Organs, EarlyView.
The IC direction in HM3 was influenced by the mitral valve height from the LV apex, distance between the LV apex and chest wall, and thoracic depth from the LV apex. Moreover, the IC direction in HM3 had little influence on the flow, PAWP and the survival rate of patients.

Management of giant left atrial thrombus late after transcatheter mitral valve-in-ring replacement using a transcatheter aortic valve: a case report

BMC Cardiovascular Disorders
Background In symptomatic high-risk patients with severe mitral valve regurgitation (MR), who are not eligible for surgery, Transcatheter edge-to-edge repair (TEER) or transcatheter mitral valve replacement (TMVR) may be an option, especially when ...

Image-based immersed boundary model of the aortic root [PDF]

arXiv, 2017
Each year, approximately 300,000 heart valve repair or replacement procedures are performed worldwide, including approximately 70,000 aortic valve replacement surgeries in the United States alone. This paper describes progress in constructing anatomically and physiologically realistic immersed boundary (IB) models of the dynamics of the aortic root and

Coronary Artery Bypass Grafting on Microaxial Flow Pump Support in Patients With Severely Reduced Left Ventricular Ejection Fraction

Artificial Organs, EarlyView.
Coronary artery revascularization with microaxial flow pump support in patients with severely reduced left ventricular ejection fraction is an emerging technique in cardiac surgery. In this manuscript, we present early results, highlight the advantages, and discuss the key limitations of this approach.

2025 Guidelines for direct oral anticoagulants: a practical guidance on the prescription, laboratory testing, peri‐operative and bleeding management

Internal Medicine Journal, EarlyView.
Abstract Direct oral anticoagulants (DOACs) are widely prescribed to prevent and treat venous and arterial thromboembolism, supported by published evidence, and are preferred over warfarin in many guidelines. Although the risk of major bleeding, in particular intracranial haemorrhage (ICH), is decreased with DOACs, gastrointestinal bleeding is ...

Fluid-structure interaction simulations of venous valves: a monolithic ALE method for large structural displacements [PDF]

arXiv, 2018
Venous valves are bicuspidal valves that ensure that blood in veins only flows back to the heart. To prevent retrograde blood flow, the two intraluminal leaflets meet in the center of the vein and occlude the vessel. In fluid-structure interaction (FSI) simulations of venous valves, the large structural displacements may lead to mesh deteriorations and
