Refining the Detection of Systemic Congestion in Severe Tricuspid Regurgitation: Echocardiography May Be the Key
A growing number of studies have shown the independent prognostic value of tricuspid regurgitation (TR) and the direct link between TR severity and adverse outcomes.1-4 However, TR not only affects prognosis but has also a negative impact on quality of life,5-7 decreasing functional capacity and increasing systemic congestion.7,8 The systolic blood backflow through the incompetent tricuspid valve reduces the forward stroke volume and cardiac output of the right ventricle (RV). Therefore, as TR worsens, pulmonary perfusion decreases, as does the venous return of oxygenated blood from the pulmonary circulation into the left ...

Treatment of patients with multiple organ dysfunction syndrome (MODS) with an electromagnetic field coupled to biorhythmically defined impulse configuration: the MicrocircMODS study
ConclusionPVT treatment was feasible and safe and could be performed without obstruction of standard patient care. An increase in microcirculatory blood flow, a rapid reduction in vasopressor use, and an improvement in global haemodynamics paralleled PVT treatment. Findings of this pilot study allowed forming a concept for a randomized trial for further proof.Graphical abstract

Ketone body 3-hydroxybutyrate elevates cardiac output through peripheral vasorelaxation and enhanced cardiac contractility
AbstractThe ketone body 3-hydroxybutyrate (3-OHB) increases cardiac output and myocardial perfusion without affecting blood pressure in humans, but the cardiovascular sites of action remain obscure. Here, we test the hypothesis in rats that 3-OHB acts directly on the heart to increase cardiac contractility and directly on blood vessels to lower systemic vascular resistance. We investigate effects of 3-OHB on (a) in vivo hemodynamics using echocardiography and invasive blood pressure measurements, (b) isolated perfused hearts in Langendorff systems, and (c) isolated arteries and veins in isometric myographs. We compare Na-3...

Predictive utility of stress tests in the detection of asymptomatic coronary artery disease in atherosclerotic stroke patients
CONCLUSION: Myocardial ischemia and CV events were infrequent and both strongly associated with ECG signs of necrosis, suggesting a low yield of stress tests and the potential for a more straightforward algorithm in the choice of patients eligible to coronary angiogram or other coronary imaging in post-stroke setting.PMID:37567133 | DOI:10.1016/j.jstrokecerebrovasdis.2023.107290

Left ventricular assist device implantation combined with hemiarch replacement for severe aortic atherosclerosis
J Thorac Dis. 2023 Jul 31;15(7):3979-3983. doi: 10.21037/jtd-23-255. Epub 2023 Jul 6.ABSTRACTImplantation of the left ventricular assist device (LVAD) has emerged as a widely employed therapeutic approach for specifically chosen individuals suffering from severe heart failure. Stroke is a well-known complication of LVAD implantation. Concomitant aortic surgeries in patients requiring LVAD implantation to avoid outflow graft anastomosis to a severe atherosclerotic aorta are unknown. We illustrate a successful LVAD implantation with hemiarch replacement for severe aortic atherosclerosis to decrease the risk of postoperative ...

Perioperative Brain Injury in Children with Aortic Arch Anomalies: A Retrospective Study of Risk Factors and Outcomes
This study examines the incidence, risk factors, and outcomes of perioperative brain injury in children undergoing aortic arch repair who had aortic arch anomalies. A total of 145 children with aortic arch anomalies in our center undergoing aortic arch repair between January 2014 and December 2022 were enrolled. There were 129 (89.0%) with coarctation of the aorta (COA) and 16 (9.7%) with interrupted aortic arch (IAA). Risk factor analysis of brain injuries was done using perioperative imaging and included symptoms of hemorrhagic stroke, arterial ischemic stroke, white matter injury, cerebral sinus venous thrombosis, and o...

Differences in symmetrical low-frequency oscillations among healthy subjects, and those with stroke or peripheral arterial disease
Conclusions: LFOs can serve as vascular perfusion biomarkers to differentiate types and degrees of vascular lesions. Therefore, LFOs have the potential to provide valuable patient information to assist researchers and clinicians in identifying specific peripheral circulatory damage subgroups.PMID:37484434 | PMC:PMC10361110 | DOI:10.1016/j.heliyon.2023.e17015

Rightward imbalanced pulmonary perfusion predicts better exercise stroke volume in children after Fallot repair
CONCLUSION: In addition to right ventricular ejection fraction, pulmonary regurgitation fraction and Fallot variant with pulmonary atresia, right pulmonary artery perfusion is a predictor of pSVi, in that rightward imbalanced pulmonary perfusion favours greater pSVi.PMID:37422422 | DOI:10.1016/j.acvd.2023.06.002
