  • Hemorrhagic pericardial tamponade in a peritoneal dialysis patient. [Journal Article]
    J Chin Med Assoc. 2021 Apr 12 [Online ahead of print]Chou YH, Lin TY, … Lin CC
  • Uremic pericarditis and pericardial effusion are possible complications among patients with end-stage renal disease. The accumulation of toxic metabolites may contribute to the pathogenesis of uremic pericarditis. Bleeding diathesis in peritoneal dialysis patients raises the risk of hemorrhagic pericardial tamponade, which is a fatal complication of peritoneal dialysis. We report a case of hemorr…
  • Genetic Complexity of Sinoatrial Node Dysfunction. [Review]
    Front Genet. 2021; 12:654925.Wallace MJ, El Refaey M, … Mohler PJ
  • The pacemaker cells of the cardiac sinoatrial node (SAN) are essential for normal cardiac automaticity. Dysfunction in cardiac pacemaking results in human sinoatrial node dysfunction (SND). SND more generally occurs in the elderly population and is associated with impaired pacemaker function causing abnormal heart rhythm. Individuals with SND have a variety of symptoms including sinus bradycardia…
  • Idiopathic right ventricular pseudoaneurysm presenting with ventricular tachycardia: a case report. [Journal Article]
    Gen Thorac Cardiovasc Surg. 2021 Apr 18 [Online ahead of print]Kumar R, Halder V, … Dahiya N
  • Right ventricular (RV) pseudoaneurysm is very rare and is seen after penetrating chest trauma, cardiac surgery, infective endocarditis, myocardial infarction, syphilis, endomyocardial biopsy, lead extraction. Idiopathic right ventricular pseudoaneurysm is even rarer. They have varied presentations depending on the etiology. Diagnosis is usually made by echocardiography. We present a case of 21-ye…
  • Autonomic dysfunction following COVID-19 infection: an early experience. [Journal Article]
    Clin Auton Res. 2021 Apr 16 [Online ahead of print]Shouman K, Vanichkachorn G, … Singer W
  • CONCLUSIONS: Abnormalities on autonomic testing were seen in the majority of patients but were mild in most cases. The most common finding was orthostatic intolerance, often without objective hemodynamic abnormalities on testing. Unmasking/exacerbation of preexisting conditions was seen. The temporal association between infection and autonomic symptoms implies a causal relationship, which however cannot be proven by this study.
  • Cardioneuroablation for Cardioinhibitory Vasovagal Syncope. [Case Reports]
    J Cardiovasc Electrophysiol. 2021 Apr 14 [Online ahead of print]John LA, Mullis A, … Winterfield JR
  • CONCLUSIONS: We performed CNA in a patient with VVS by utilizing a novel approach of combined use of high density mapping and fractionation mapping software. With this approach, we were able to detect fractionation in all GP sites and demonstrate acute vagal response. This workflow may allow for a new, standardized technique suitable for widespread use.

  • Type 1 narcolepsy without cataplexy and treatment progress: a case report. [Journal Article]
    Ann Palliat Med. 2021 Mar; 10(3):3491-3494.Huang R, Ding X, … Chen X
  • Narcolepsy is a sleep disorder with the main manifestations of excessive daytime sleepiness, cataplexy, sleep paralysis, sleep hallucinations, and nighttime sleep disturbance. It is still not fully recognized by clinicians, and many patients are often misdiagnosed with epilepsy, syncope, or mental disorders. In the present study, we report the first case of narcolepsy diagnosed at the district, w…
  • Vasovagal reactions following venepuncture result in aberrant stress-induced cortisol levels. [Journal Article]
    Psychoneuroendocrinology. 2021 Apr 03; 128:105220.Dalile B, Verbeke K, Van Oudenhove L
  • Venepuncture is recognized as a potent stressor and, by activating the hypothalamic-pituitary-adrenal (HPA) axis, can interfere with measuring subsequent HPA axis indices such as cortisol. A resting period of 110 min is recommended between venepuncture and the commencement of psychosocial stress induction or cortisol measurement to allow cortisol levels to return to baseline first. In experiment …
  • Potential Neurologic Manifestations of COVID-19. [Review]
    Neurol Clin Pract. 2021 Apr; 11(2):e135-e146.Nordvig AS, Fong KT, … Elkind MSV
  • Neurologic complications are increasingly recognized in the coronavirus disease 2019 (COVID-19) pandemic. COVID-19 is caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This coronavirus is related to severe acute respiratory syndrome coronavirus (SARS-CoV) and other human coronavirus-related illnesses that are associated with neurologic symptoms. These symptoms rais…
  • Deciphering Genetic Variants of Warfarin Metabolism in Children With Ventricular Assist Devices. [Journal Article]
    Pediatr Cardiol. 2021 Apr 10 [Online ahead of print]Baban A, Iodice FG, … Amodeo A
  • Warfarin is prescribed in patients with ventricular assist devices (VADs). Dosage depends on several factors including the underlying genotype. These include polymorphisms of genes encoding cytochrome P450 enzymes, the main ones being CYP2C9, VKORC1, and CYP4F2. The objectives of this study were to evaluate the prevalence of CY2CP9 1*2*3*, VKORC1, and CYP4F2 in children with VADs and the time to …
  • Novel dilated cardiomyopathy associated to Calreticulin and Myo7A gene mutation in Usher syndrome. [Case Reports]
    ESC Heart Fail. 2021 Apr 09 [Online ahead of print]Frustaci A, De Luca A, … Russo MA
  • We report a novel cardiomyopathy associated to Usher syndrome and related to combined mutation of MYO7A and Calreticulin genes. A 37-year-old man with deafness and vision impairment because of retinitis pigmentosa since childhood and a MYO7A gene mutation suggesting Usher syndrome, developed a dilated cardiomyopathy with ventricular tachyarrhythmias and recurrent syncope. At magnetic resonance ca…
  • Adenosine and neurohumoral syncope. [Journal Article]
    Minerva Med. 2021 Apr 09 [Online ahead of print]Deharo JC, Brignole M, Guieu R
  • Either central or peripheral baroreceptor reflex abnormalities and/or alterations in neurohumoral mechanisms play a pivotal role in the genesis of neurally mediated syncope. Thus, improving our knowledge of the biochemical mechanisms underlying specific forms of neurally mediated syncope (more properly termed 'neurohumoral syncope') might allow the development of new therapies that are effective …
  • Aortic Intimo-intimal Intussusception: A Pooled Analysis of Published Reports. [Review]
    Ann Vasc Surg. 2021 Apr 05 [Online ahead of print]Wu ZY, Miao YQ, … Li YJ
  • CONCLUSIONS: AoII is a rare form of aortic dissection with high mortality. Antegrade orientation of the intima flap was more accompanied with neurological disorders and asymmetric blood pressure, while retrograde orientation mostly manifested with aortic regurgitation. Application of multiple imaging examinations may detect this rare entity in time.
  • [Crossed eyes on arterial blood pressure in sitting position]. [Case Reports]
    Rev Med Liege. 2021 Apr; 76(4):221-223.Scheen AJ, Marchand M, Philips JC
  • Prolonged standing or even sitting position can induce a fall in arterial blood pressure because of gravity that provokes a blood volume sequestration in lower limbs. Such a phenomenon may be associated with orthostatic dizziness or sometimes syncope. We present the image of a continuous monitoring using a Finometer® of systolic blood pressure and heart rate. Crossing legs while in sitting positi…
