Warfarin faring better: Vitamin K antagonists beat rivaroxaban and apixaban in the INVICTUS and PROACT Xa trials
J Thromb Haemost. 2023 Jul 8:S1538-7836(23)00523-8. doi: 10.1016/j.jtha.2023.06.036. Online ahead of print.ABSTRACTAlthough guidelines give preference to the direct oral anticoagulants (DOACs) over vitamin K antagonists (VKAs) for stroke prevention in most patients with atrial fibrillation (AF), DOACs are not recommended in those with rheumatic heart disease or mechanical heart valves. The results of the INVICTUS trial (Investigation of Rheumatic AF Treatment Using Vitamin K Antagonists, Rivaroxaban or Aspirin Studies), which compared rivaroxaban with a VKA in patients with rheumatic heart disease associated AF, and the PR...

Rheumatic Heart Disease Echocardiogram Screening by Nonexperts: A Review
Rheumatic Heart Disease occurs when heart valves are damaged by Rheumatic Fever. Young First Nations Australians aged between 5 –14 years are at high risk of developing Rheumatic Fever. Complications of Rheumatic Heart Disease include atrial fibrillation, endocarditis, heart failure, and stroke. Early disease detection is essential as Acute Rheumatic Fever is easily treatable if detected early.

Early safety and feasibility of a first-in-class biomimetic transcatheter aortic valve - DurAVR
CONCLUSIONS: Preliminary results from the FIH study with DurAVR THV demonstrate a good safety profile with promising haemodynamic performance sustained at 1 year and restoration of near-normal flow dynamics. Further clinical investigation is warranted to evaluate how DurAVR THV may play a role in addressing the challenge of lifetime management in AS patients.PMID:37334801 | DOI:10.4244/EIJ-D-23-00282

The effect of treatment strategy on long-term follow-up results in patients with nonvalvular atrial fibrillation in Turkey: AFTER-2 subgroup analysis
CONCLUSION: It was found that rhythm control strategy is preferred in AF patients in Turkey. We found a lower rate of ischemic CVD/TIA in patients in the rhythm control group. Although no difference was observed in mortality rates, we found a higher rate of hospitalization in the rhythm control group.PMID:37329474 | DOI:10.1007/s40520-023-02467-y

Sociodemographic disparities in concomitant left atrial appendage occlusion during cardiac valve operations
by Ayesha P. Ng, Nikhil Chervu, Yas Sanaiha, Amulya Vadlakonda, Elsa Kronen, Peyman Benharash BackgroundSociodemographic disparities in atrial fibrillation (AF) management and thromboembolic prophylaxis have previously been reported, which may involve inequitable access to left atrial appendage occlusion (LAAO) during cardiac surgery. The present study aimed to evaluate the association of LAAO utilization with sex, race, and hospital region among patients with AF undergoing heart valve operations. MethodsAdults with AF undergoing valve replacement/repair in the 2012 –2019 National Inpatient Sample were identified and str...

Effect of multicomponent rehabilitation on independence and functioning in elderly patients with common age-associated diseases: protocol for a scoping review (REHOLD)
Introduction Elderly patients after hospitalisation for acute events on account of age-related diseases (eg, joint or heart valve replacement surgery) are often characterised by a remarkably reduced functional health. Multicomponent rehabilitation (MR) is considered an appropriate approach to restore the functioning of these patients. However, its efficacy in improving functioning-related outcomes such as care dependency, activities of daily living (ADL), physical function and health-related quality of life (HRQL) remains unclarified. We outline the research framework of a scoping review designed to map the available evide...

Efficacy and safety of carbon dioxide insufflation for brain protection for patients undergoing planned left-sided open heart valve surgery: protocol for a multicentre, placebo-controlled, blinded, randomised controlled trial (the CO2 Study)
Introduction Brain injury is common following open heart valve surgery. Carbon dioxide insufflation (CDI) has been proposed to reduce the incidence of brain injury by reducing the number of air microemboli entering the bloodstream in surgery. The CO2 Study will evaluate the efficacy and safety of CDI in patients undergoing planned left-sided open heart valve surgery. Methods and analysis The CO2 Study is a multicentre, blinded, placebo-controlled, randomised controlled trial. Seven-hundred and four patients aged 50 years and over undergoing planned left-sided heart valve surgery will be recruited to the study, from at lea...

Extreme preterm neonate with fetal warfarin syndrome
A 25+3 week gestation male infant weighing 493 g was delivered via caesarean section for intrauterine growth restriction and abnormal Dopplers. The mother was on long-term thromboprophylactic warfarin 5 mg/day due to her prosthetic mechanical heart valve following childhood rheumatic fever. Once pregnancy was diagnosed, at 4+0 weeks’ gestation, warfarin was discontinued and low-molecular-weight heparin was started. Warfarin was recommenced at 12+1 weeks’ gestation after a small maternal stroke. Neonatal dysmorphic facial features were noted, most obviously nasal hypoplasia (figure 1). The hypoplastic upper airw...

Sensors, Vol. 23, Pages 3829: First Ex Vivo Animal Study of a Biological Heart Valve Prosthesis Sensorized with Intravalvular Impedance
In this study, for the first time, we investigate ex vivo the IVI sensing applied to a BHV when it is surrounded by biological tissue, similar to a real implant condition. A commercial model of BHV was sensorized with three miniaturized electrodes embedded in the commissures of the valve leaflets and connected to an external impedance measurement unit. To perform ex vivo animal tests, the sensorized BHV was implanted in the aortic position of an explanted porcine heart, which was connected to a cardiac BioSimulator platform. The IVI signal was recorded in different dynamic cardiac conditions reproduced with the BioSimulato...

Is There a Role for Vitamin K Antagonist in the Management of Atrial Fibrillation in 2023?
AbstractPurpose of ReviewTo address the following question: Are vitamin K antagonists (VKA) obsolete as stroke prevention therapy for patients with atrial fibrillation (AF) and thromboembolic risk factors?Recent FindingsA patient-level meta-analysis of the pivotal phase III randomized trials confirmed the favorable treatment effect of direct oral anticoagulants (DOAC) over VKA in multiple key patient subgroups. Among patients with AF and rheumatic heart disease (85% of whom had mitral stenosis), a randomized trial showed that rivaroxaban was not superior to VKA for stroke prevention. Caution should be exercised when prescr...

Stroke and Noninfective Native Valvular Disease
AbstractPurpose of ReviewEmbolic stroke of undetermined source is a challenging clinical entity. While less common than atrial fibrillation and endocarditis, many noninfective heart valve lesions have been associated with stroke and may be considered as culprits for cerebral infarcts when other more common causes are excluded. This review discusses the epidemiology, pathophysiology, and management of noninfective valvular diseases that are commonly associated with stroke.Recent FindingsCalcific debris from degenerating aortic and mitral valves may embolize to the cerebral vasculature causing small- or large-vessel ischemia...
