Maternal and Fetal Outcomes of Anticoagulation in Pregnant Women With Mechanical Heart Valves

open access: yesJournal of the American College of Cardiology, 2017
Background Anticoagulation for mechanical heart valves during pregnancy is essential to prevent thromboembolic events. Each regimen has drawbacks with regard to maternal or fetal risk. Objectives This meta-analysis sought to estimate and compare the risk

Fatores de risco em operações valvares: análise de 412 casos

open access: yesBrazilian Journal of Cardiovascular Surgery, 1997
O tratamento cirúrgico das valvopatias é muito freqüente e sua mortalidade ainda não se aproxima de zero. Neste estudo, procuramos identificar diversos fatores que poderiam aumentar o risco cirúrgico nestes procedimentos.

An investigation of the anisotropic mechanical properties and anatomical structure of porcine atrioventricular heart valves.

open access: yesJournal of The Mechanical Behavior of Biomedical Materials, 2018
Valvular heart diseases are complex disorders, varying in pathophysiological mechanism and affected valve components. Understanding the effects of these diseases on valve functionality requires a thorough characterization of the mechanics and structure ...

Optimization of anticoagulant therapy in patients undergoing mechanical heart valve replacement

open access: yesФундаментальная и клиническая медицина, 2023
Acquired heart defects have a high prevalence among patients of different age groups and represent a significant social problem. To date, surgery remains the only effective option to treat acquired heart disease, and replacement of the dysfunctional ...

Prosthetic Heart Valves

open access: yesInternational Journal of Clinical Practice, 2014
Heart valve replacements improve symptoms and life expectancy but may have potential problems. Biological replacements have limited durability but do not require anticoagulation and are usually used for the relatively elderly. Mechanical valves have a virtually zero primary failure rate but require anticoagulation and are usually used for the ...

Recellularization of decellularized heart valves: Progress toward the tissue-engineered heart valve

open access: yesJournal of Tissue Engineering, 2017
The tissue-engineered heart valve portends a new era in the field of valve replacement. Decellularized heart valves are of great interest as a scaffold for the tissue-engineered heart valve due to their naturally bioactive composition, clinical relevance

Study on the Accuracy of Structural and FSI Heart Valves Simulations

open access: yesCardiovascular Engineering and Technology, 2018
The performance of heart valves, either native or artificial, can be evaluated by means of finite element analyses, either from a structural or a fluid–structure interaction (FSI) point of view. The latter captures the coupling between the valve leaflets

Evaluation of the Utility of Baseline Echocardiogram in Patients With Standard Risk Precursor B‐Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
Abstract Background A routine baseline echocardiogram is often obtained prior to anthracycline administration in children with cancer. The utility of baseline echocardiogram is unclear in patients with standard risk B‐cell acute lymphoblastic leukemia (SR B‐ALL) as their anthracycline cumulative dose is low.

Upacicalcet: A Novel Intravenous Calcimimetic Agent for Patients Undergoing Hemodialysis With Secondary Hyperparathyroidism

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.
