Increased Risk of Surgical Aortic Valve Replacement After Prior Transcatheter Versus Surgical Aortic Valve Replacement with Concomitant Valve Disease.
Ann Thorac Surg
January 2025
Department of Cardiac Surgery, University of Michigan, Ann Arbor, MI.
Background: The etiology of increased risk for reoperation after transcatheter aortic valve replacement (TAVR) versus prior surgical aortic valve replacement (SAVR) is poorly understood. This study evaluated the impact of concomitant mitral and tricuspid valve disease on associated risk of TAVR explant.
Methods: Patients undergoing aortic valve replacement after prior SAVR or TAVR were extracted from the Society of Thoracic Surgeons Adult Cardiac Surgery Database (2011-2021).
Impact of measurement location on direct mitral regurgitation quantification using 4D flow CMR.
J Cardiovasc Magn Reson
January 2025
Department of Radiology, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA. Electronic address:
Background: Four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) shows promise for quantifying mitral regurgitation (MR) by allowing for direct regurgitant volume (RVol) measurement using a plane precisely placed at the MR jet. However, the ideal location of a measurement plane remains unclear. This study aims to systematically examine how varying measurement locations affect RVol quantification and determine the optimal location using the momentum conservation principle of a free jet.

Department of Cardiology, Hospital of Lithuanian University of Health Sciences Kauno Klinikos, Lithuanian University of Health Sciences, 2 Eivenių Str., LT-50009 Kaunas, Lithuania.
: Transcatheter aortic valve implantation (TAVI) has emerged as a pivotal intervention for managing severe aortic stenosis in high-risk surgical patients. : This study aimed to evaluate the impacts of procedural factors and patient characteristics on TAVI outcomes, with a focus on survival rates, cardiac mortality, and associated complications. : A retrospective, single-center study involving 224 patients who underwent TAVI at the Lithuanian University of Health Sciences from September 2021 to April 2023 was conducted.

Diagnostics (Basel)
January 2025
Department of Human Science and Promotion of Quality of Life, San Raffaele Open University, 00163 Rome, Italy.
Marfan syndrome (MFS) is a genetic disorder affecting connective tissue, often leading to cardiovascular complications such as aortic aneurysms and mitral valve prolapse. Cardiovascular multimodality imaging plays a crucial role in the diagnosis, monitoring, and management of MFS patients. This review explores the advancements in echocardiography, cardiovascular magnetic resonance (CMR), cardiac computed tomography (CCT), and nuclear medicine techniques in MFS.

Egypt Heart J
January 2025
Intensivista Pediátrico, Fundación Clínica Infantil Club Noel, Cali, Colombia.
Background: The mitroaortic intervalvular fibrosa is an avascular structure near the left ventricular outflow tract, between the mitral and aortic valves. Mitroaortic intervalvular fibrosa complications, such as tamponade, hemopericardium, and abscesses, are rare and often diagnosed postmortem. On the other hand, the COVID-19 pandemic notably impacted pediatric patients with congenital heart diseases, who frequently presented cardiac complications including arrhythmias, elevated troponins, myocarditis, and heart failure.
